i-Tree is a website designed to help property owners decide which tree species they want to plant and where they should plant them in their home or commercial property landscape. I-Tree was developed by some of the big players in U.S. tree care as an educational and practical tool, and is FREE to use. Combining data points and technology, this website can tell you actual benefits of planting a tree in a specific spot in your yard.
Heartwood loves to plant trees, so getting top quality nursery stock is always important. In a typical year we order shade trees, evergreens, shrubs, and fruit trees from a variety of locations. We prefer to order from nurseries within Wisconsin, its keep the shipping costs down and the product is usually straight from the field. Below are the three that we are using this year to make up the spring plant sale offering.
We have posted before about using dynamic cabling to support smaller splits and/or limbs or branches that can use additional support. In the last year, we have been deploying a steel ring as a hub in static (metal/no stretch) cabling systems. This case study shows what we saw in a recent sugar maple and how we decided to install a hub with four legs (cables) to hold this large and valuable tree together.
The defined practice of forest bathing is relatively young, but the intuitive act of healing in nature is nothing new. We evolved in forests, and forest bathing has been shown to decrease levels of stress hormones, improve the immune system and mood, and increase creative problem solving. I am certainly not the first to write about the benefits of spending time outdoors. In the words of John Muir, “Thousands of tired, nerve-shaken, over-civilized people are beginning to find out that going to the mountains is going home. Wilderness is a necessity.”
Colorado blue spruce (Picea pungens) is an evergreen tree widely planted in residential gardens in Wisconsin. Its structural, columnar form is commonly used to build windbreaks or privacy screens in backyards throughout the United States. The year round blue-green coloration provides winter interest in the Midwest garden.
Have you ever gone down to do the splits and not be able to get yourself back up without help? Well, trees with structural deficiencies can actually split in a similar manner. Two arms of a trunk may stretch wide during a wind event, but they can't pull themselves back together afterward. The typical split we see is like this one below, with the drill and drill bit through the trunk.
To fix a splitting tree, we apply structural support in the form of cabling or bracing. This hackberry split about 7' up from the ground and we are drilling two holes through the trunk so we can install threaded rods to hold the split together. It's not an easy task. In the above photo, we are using a 4' long drill bit and a drill that weighs around 15 pounds. The hardest part is when the drill bit gets completely stuck in the tree! Its happens too often and can be a scary moment.
Here is a good profile shot of the two rods with the washers and nuts on the end. One of the braces goes through near the top of the split and the other is installed around 20" above the lower brace. The braces are around 30-35" long from end to end. The rods are cut as close to the trunk as possible and then the ends are pounded with a hammer to prevent the nut from backing off.
In most normal tree repairs to a split trunk, the work does not stop at the brace. The top of the tree is where all the leverage happens, and it also requires support in the form of a static steel cable. This cable helps to hold the tree crown together, reducing the forces being placed on the brace, and helps to hold the tree together.
The last picture shows a detail of a brace in a different tree, viewed from above. This brace is about 6 feet long and required lots of effort from many people to get installed. It was well worth it, for this tree a heritage burr oak on Lakeside in Madison. A truly incredible specimen, the back side of this tree was split and had been split for some time. We had to install two cables to hold the top together and then put two super long braces through the trunks.
Each time we do a brace there is a challenge that pops up. These challenges probably explain why this is an underutilized application. Cutting the branch off is usually easier, but often is not what is best for the tree.
In both the above trees, there was no decay present so the bolts and cables replaced the wood that is supposed to hold the trunks together. The combination of bracing and cabling can stabilize a split tree and be an alternative to tree removal. Unlike the braces on a teenager, tree braces and cables are permanent!
This is Big Bertha the fir tree. She lives south of Mt Horeb and was named by a tree loving 7-year-old. The mother of the boy called us and asked if we could stitch it back up after a summer storm. The possibility of cutting it down due to the split between the two halves was too much for the boy to manage and he pleaded with mom to call us.
The friendly guy at the bottom of the photo is Alex; he is standing in front of his handy work. He cleaned up the failed branch (see cut on trunk) and then took it upon himself to install the dynamic cables; you can see two cables there, installed as high as possible. These cables are more effective the higher up you put them in the tree.
Cables have a tensile strength of over 10,000 pounds making them very strong. The best feature of the support system is its stretch which allows the tree to move freely compared to rigid static steel cables. The other nice attribute of dynamic cables is there is no hardware installed or drilled into the tree. A simple knot is tied around the branch with room for future growth.
The one drawback to the dynamic cable is its lifespan. These cables need to be inspected every couple of years and replaced after 5-10 years due to potential wear and degradation over time. When compared to static cables the dynamic is a bit less expensive in the short term, but in the long run they would likely work out to be the same amount of investment depending on how long the tree remains on the property.
Over the years, dynamic cabling has allowed us to prune suspect branches aggressively to reduce risk and then install the cable to provide a bit more insurance against branch failure. This is a tool that can help keep trees safely in the landscape longer. Long live Big Bertha!
Paper Birch and its white chalky bark is well recognized across the state. In the last 20 to 30 years, landscapers and nurseries have strayed from the paper birch to whitespire birch or grey birch because paper birch has a reputation for being susceptible to bronze birch borer, a native pest. In reality, when properly placed, a paper birch can thrive and not succumb to bronze birch borer. Paper birch is an understory tree and should be planted in partial shade among other trees. Cool root zones are the key for this tree. Bring back that native yellow fall color to your yard!
I like the upright growth habitat favored by the paper birch. Fewer branches gives the paper birch an aesthetic advantage over the messy/super thick grey birch. We often prune grey birch to look like paper birch (doesn't that sound silly?) by removing or thinning the branching to clean up its appearance.
We plant single-stem paper birch each spring as a bare root tree. Go to our store or contact us today to inquire about purchasing a paper birch for your yard. If you are inclined to plant a paper birch yourself, AWESOME! Remember that birch is an understory tree and should be planted in partial shade. I have noticed that paper birch on the east and north side of homes do well because the house shades the root zone in our hot summer afternoons.
Here are some of the highlights of our recent log salvage adventures. I call them “adventures” because it would be much easier to chunk the log up into firewood and throw it in the back of the truck, but who likes to take the easy road? Although salvaging the trees we cut down can sometimes be an onerous task, it is a huge honor to turn the trees folks are “throwing away” into beautiful pieces of heirloom-quality furniture to be enjoyed for generations. We are proud to undertake this work.
This photo below shows a white oak log we had to cut in half the long way to get it out under a fence and around a house. A local small sawmill operator came out to rip the two logs in half and we loaded them up on his trailer for further processing. These guys has retrieved many of our logs and turned them into huge slabs, decking, and dimensional lumber.
There are endless uses for urban salvage wood if you are willing to put the extra effort into finding what you need and then likely paying a bit more for the material. After all, salvaging a log in a backyard is a lot harder than clearing a forest! In my mind, urban wood has a lot of interesting character to it and is worth the extra cost.
The next image shows a red oak log from a property off Nakoma that Jeff is milling into slabs. This tree was a perfect specimen with no structural issues whatsoever, but it died a quick death due to oak wilt. While it is sad to see perfect trees die quickly without warning, I am glad to see salvaged pieces put to good use. While writing this I returned to the yard and found Jeff and the gang milling the logs. They managed to get 15 gigantic slabs from the trunk. They were 12' long, 3-4' wide and 3.5" thick. Lumber this large can easy become a handsome dinner or banquet table for a very large dining room!
The stack of lumber below is another project we worked on with Jeff on the outskirts of Fitchburg. My daughter couldn't resist being in the photo, she is on top of a stack of oak and walnut boards. The client had a couple standing dead trees and a couple other walnuts that he wanted to thin out. We were able to do all the removals on a Thursday and by Saturday night, all the lumber was milled and ready for drying. We are not always this efficient and timely, but sometimes the stars align.
Lastly, pictured below is a stately white oak that perished in the Monroe Street neighborhood. Garrett is in the tree making the final cut to get the tree to a safe height to fell. Once on the ground, we could see the trunk base had a little rot, but nothing too bad considering the log was around 40" wide at the base and over 20' long! This seemed like another excellent candidate for salvage and we were able to get a number of large, healthy planks of wood out of this tree.
The people salvaging urban wood are important players in helping us create greater connections to our trees. When logs are diced up for firewood, we miss out on all those awesome tables and desks made from one slab of wood! While many tree services would rather get a tree out of a yard the fastest way possible, we think it's wasteful to simply cut big, old trees into chunks, to be burned as firewood. We are interested salvaging urban-sourced trees in the most responsible manner possible, even if it takes some (often a LOT of) extra effort.
This last photo is our clutch of logs from the winter. Amongst them, you will find oak, ash, elm, spruce, pine, maple and hickory trees. Believe it or not, we do more pruning than removing on an annual basis but even when you don't focus on removals you end up with a lot of logs!
If you are interested in purchasing salvaged urban wood for a project, there are a number of places you can look in Madison. The Wood Cycle of Fitchberg hauls and mills logs that end up for sale at Habitat for Humanity Restore on Monona Drive. Please inquire and we can help you locate a quality operator with expertise in whatever you are interested in.
Have you ever wondered about the big trees in Madison, Wisconsin? Towering oaks with gnarled branches and thick trunks are scattered throughout the city. If you think these trees are unusual, you are correct. Some of them are hundreds of years old and have witnessed many generations and historical events. These old oaks are also significant because they are the last remnants of the oak savannas that used to cover southern Wisconsin.
Southern Wisconsin looked very different 200 years ago. Today, when we drive around Dane County, we see forest patches in between farms and towns. Before European settlement, however, this area was a landscape of vast prairies with oak trees here and there. Treeless prairies and oak savannas are found in dry, sunny regions, and they used to cover millions of acres of land across the Midwest. These plant communities are fire-adapted: they rely on yearly low-intensity wildfires to burn up dead grasses, fertilize the soil, and kill most sprouting trees. Oaks have deep roots and thick bark that enable them to be the lone survivors of such fires. Grown in open savannas without competition from other trees, oak trees can stretch their limbs wide, forming the classic oak silhouette.
In the 1800s, settlers turned southern Wisconsin’s flat, fertile prairies into farms while suppressing wildfires to protect their crops and towns. In the absence of fire, trees like Red Maples eventually took over former oak savannas. Oaks don’t compete well in thick forests because other tree species are more effective at accessing water, soil nutrients, and sunlight.
Today, conservation groups like The Nature Conservancy try to promote oak savannas because they offer unique habitat for rare songbirds and because their acorns feed a variety of small mammals. Conservationists use controlled fires to burn off competing tree species to make room for oaks to grow. The savannas in the UW Arboretum and Picnic Point are great examples of such efforts. Unfortunately, it’s more difficult to support young oaks in urban areas where fire isn’t an option. The big oaks around Madison are slowly succumbing to age, disease, and storm damage. If you have oaks in your yard, make sure to give them the TLC they need. We strongly recommend careful pruning and inspection for decay pockets.
Do you have space for a new tree, or are you looking to replace a fallen one? There are lots of great planting options. Burr oak, white oak, pin oak, red oak, swamp white oak, and regal prince oak are attractive trees that can grow into majestic giants with the right care. At Heartwood, we’re passionate about helping you through all steps of the process, from safe removal of old trees to new planting, aerial inspection, and conservative pruning. We love old oaks, and we want to help you maintain these trees in your landscape for years to come. Contact us if you need help with your trees or if you simply have questions!
Oak Wilt is a tree disease caused by a non-native fungal pathogen which can afflict White and Red Oaks in the Eastern United States. The disease is more severe in Red Oak species, such as the Northern Red Oak and Northern Pin Oak. Red Oaks will die rather quickly from Oak Wilt, while White Oaks tend to contain the spread of the disease to infected branches.
Oak Wilt is prevalent in the southern Wisconsin counties of Wisconsin, but has not yet spread to some northern areas of the state. This article will introduce you to the signs and symptoms of Oak Wilt (Ceratocystis fagacearum), as well as management strategies we offer concerned homeowners.
One of the first symptoms homeowners notice is the "flagging" of branches in your beloved Oak tree. These are branches with dried and dead leaves occurring in the upper canopy of trees in full sun. These symptoms may occur following storm damage in the summer, because breaks in the tree bark make the tree vulnerable to disease. If you notice summer storm damage on an oak tree, calling an arborist immediately is a great pro-active step to avoiding Oak Wilt.
Another symptom of Oak Wilt is the brown discoloration of leaves starting from the tip of the leaf and progressing towards the midrib, though this may be irregular. This symptom can be accompanied by uncharacteristic leaf drop. As mentioned earlier, this disease progresses rather quickly in Red Oaks, leading to rapid death, while White Oaks may only show wilting leaves the first year with symptoms progressing more slowly over the next few years.
Symptoms are useful for leading to a disease diagnosis in plants. Symptoms area plants' reaction to a disease, while the signs discussed next are the causation. Be aware that symptoms can be shared across many tree diseases, which is a common cause of misdiagnosis. The best way to determine if a tree has oak wilt is to take a branch sample from the affected portion of the tree and ask an arborist or other tree professional to evaluate.
The Oak Wilt Fungus can spread through intersections of Oak roots, which can make its spread difficult to control. The fungal mats in the trees' cambium produce volatile compounds that attract the vector for this disease. (A vector is the transmission factor that causes new infections of Oak Wilt in healthy trees by entering wounds.) Two species of sap beetles are the culprits for overland Oak Wilt transmission. Signs of Oak Wilt would be either the fungal pressure pads found under the tree bark or presence of the beetle.
Oaks are particularly susceptible to Oak Wilt infection in the spring and summer, while the beetles are infecting fresh wounds. For this reason, you should only prune Oak trees between November (first hard frost is a good measure) and March if possible. Any wounding from storms occurring between the spring or summer months should still be pruned as soon as possible to prevent infection, and should also be treated with a pruning sealant.
If you have an existing Oak infected with Oak Wilt that needs to be removed, you should:
- Schedule a removal in the winter months to prevent further spread to neighboring trees.
- Some homeowners may also consider trenching around infected trees to prevent root spread of the fungus. This measure is not a guarantee because you do not know for sure if all the root grafts between trees will be severed, but is a good alternative to the fungal treatment.
- Another more effective preventative measure is to treat your trees with a systemic injection of propiconazole, a fungicide that can protect high value trees for up to two years. This treatment can slow the infection of White Oaks with less than 30% crown decay symptoms, but is not recommended for infected Red Oak trees.
We want to help protect your Oak trees and maintain the health of our urban canopy. Contact Heartwood if you need help managing or caring for your oaks ,or if you just have a question.
Every year, we "straighten up" quite a few trees for various reasons. Trees typically start leaning due to a high wind event, sometimes combined with heavy rains and wet soil. A leaning tree isn't necessarily unhealthy (it really depends on the root condition), but they do look funny in the context of a manicured suburban landscape. This learning spruce tree below made a great case study on straightening tipping trees.
This tree took the cake in terms of size for leaning trees straightened by Heartwood in 2016. This guy was 25-30’ tall, and as you can see it was tipping/leaning a lot. The wet weather in spring (which loosens soil and destabilizes roots systems), combined with strong winds later in the year (which levers trees strongly and pulls on their roots), proved too much for many shallow-rooted spruce trees like this one.
A leaning tree can be saved depending on the severity of the lean and the condition of the tree. Often if the roots are exposed or the lean is too great, there is little that can be done to save a tree. This customer really wanted to save the tree, so we gave it a shot. As far as we know the tree is still healthy!
The uprighting process is not too complicated, as you can see in the second photo. We rigged one rope through a pulley, attached one end to the spruce, attached the other to the poplar, and set up a 5:1 mechanical advantage system. The 5-to-1 is the short yellow rope above the drooping orange line. The mechanical advantage helps create super-human strength to pull the tree up straight, multiplying the force of the person hauling on the line roughly 5 times (though we lose some energy to the friction of the ropes through the pulleys and hardware).
Once straight, we install three poly cables (ropes) to hold the tree in place. In this case, two cables went to posts pounded into the ground to help provide stability on each side. The other cable was attached to the poplar trunk, which is the main support for the spruce.
The biggest concern with leaning trees is whether the roots are healthy and strong enough to attempt to straighten the tree. In this case, the roots were still intact and buried. Beyond the roots, the next concern is what to tether the tree to. In this case we had a sturdy tree that provided me confidence that this could be done. If we had to hold this tree up with only three metal posts, we may have reconsidered our options.
Once the tree is straight expect to leave the cables in for several years at a minimum, especially with a tree of this size. Each tree is unique so there is really no good way to know how long the tree might need support. Over time the cables will just need to be checked for proper tension. When checking the tension, you can always let out the cable a bit and see what happens; if the tree does not move at all when the cables are loosened, it may have reestablished enough root system to stand straight on its own. I wish there was a more exact science to this but there really is not!
We had many successes righting many "ships" last year, but we also had some failures. In any case, we forge on willing to straighten just about any tree out there if the owner wants to give it a shot. I mention this because tree straightening is not always successful, but why not try it if it’s a safe option?
We are always striving to keep as many felled logs in productive use as possible. By "productive use," I mean preventing good wood from becoming firewood or woodchips and instead becoming useful and/or beautiful products that will be treasured for decades or even centuries. Despite our best efforts, we still end up with lots of firewood and woods chips (both free for customers)!
Gene Delcourt of Humble Crossings located on the east side of Madison is the main destination of all of our spruce logs. Spruce is probably the most common tree removal we do and that means there are a lot of nice logs in need of a good repurposing. Gene happily takes them all and turns them into beautiful 100% wood caskets, just like in the old days.
I’m guessing Gene has picked up or we have delivered at least 30-40 logs this year for his projects. Gene can be contacted directly for inquiries into his creations at (608) 354-6923.
Before we found Gene, our spruce logs were destined for the tub grinder at the Madison city disposal center because few artisans or builders are interested in using spruce wood. Gene loves working with spruce because its readily available and usually involves removing a dying tree. The first question Gene asks is “Was it dead?” This basic question tells me Heartwood and Gene are operating with the same interests at heart.
We will continue striving to salvage as many logs as possible. With people like Gene as partners in this effort, I think we can find good homes for the lumber. If you have a need or desire for whole logs, please contact us to see if we might be a good fit.
Road salt is very effective at clearing ice from roadways and walks, but plants bear the brunt of the leftovers. Once the salts dissolves, it infiltrates the soil, creating a salty mess.
In the photo below are two black walnuts situated at the end of a parking lot. You can see the snow piles at the base of each tree and the salt-coated parking lot. The customer called because there have been dead branches falling from the trees. I looked at the trees after all the leaves were off and thought it would be a straightforward canopy cleaning... remove a few dead branches for safety.
Once we climbed up into the trees it became clear that salt was slowing killing these trees. Most of the branches in the upper canopy had dead tips. The branch tip is where the most vigorous growth occurs, and they were dying off. The salt build up in the soil was actually preventing the tree from transporting water to the tips of the tree.
If you do a quick internet search, you will find the many ways that salt harm woody plants. The biggest reason is salt’s ability to prevent plants from absorbing or taking up water, also known as physiological drought. Salt spray along roadsides is another common form of salt damage. The spray coats the dormant buds and essentially burns them, killing the buds or slowing their growth.
When using salt on your property:
- Use salt sparingly and clean up large spills or piles.
- Mix some sand into your salt to “stretch” the salt out bit more.
- Avoid piling snow with lots of salt on the root zone of trees and shrubs.
- Protect valuable plants with physical barriers to keep salt off of foliage and out of root zone.
Resources for preventing salt damage or minimizing it:
• Plant salt tolerant varieties of trees and shrubs. This is really good!
• If you have a pile of salt-laden snow at the base of your tree or shrub that you want to protect, you can flush the soil out with water before bud-break once the ground has thawed. Basically you would have to flood the root zone to purge all the built-up salts present.
• Use only sand or familiarize yourself with an ice scraper. My dad can attest to my extensive use of this tool as a kid, so I could shoot hoops all winter outside.
There is a lot of good info on the web about salt and the damage it can inflict on plants and trees. This is a only a starter to get you thinking about it. Educate yourself and others on the consequences of salt, so as a community we can keep our canopy as healthy as possible.
So as proof that we can learn and advance our skills, with great pride I want to show you our newest technique for cabling some autumn blaze maples. Cameron of Lundin Tree Care was not super impressed when I told him about our new technique. “I’ve been doing it that way for a while now.” Well, I'm glad we caught up!
Anyways, you can see the four sides of the cable that form a basket or loop in the upper 1/3 of the tree. We are moving towards this style because so often the tops of these type of maple are loaded with vertical growing trunks. Putting a basket around all the trunks helps to prevent any of them failing during a storm event. The conventional way would be to install cables between two trunks. Autumn blaze is notorious for many, many trunks (leaders) which means lots of cables going between the many leaders.
Installing the basket around all of the leaders solves this problem and protects the entire center of the tree. It might not be completely visible in the photo, but we did do a pretty extensive train prune on the tree before installing the basket. The last reason that this technique works is because the tree is relatively small at this point. In ten years the tree will be much bigger/taller and require a different system to hold it together.
This article distills our years of tree planting experience to illustrate the differences between bare root and “balled and burlapped” (aka “B&B") tree planting techniques.
Bare Root Planting
Planting a tree in the "bare root" style is very literal. If you look at the below photo, you'll see the tree is all plant: no soil included in the root mass, only roots and the trunk.
Balled and Burlapped Planting (aka "B&B")
The alternative to bare root planting is the a "B&B tree," which stands for balled and burlapped. The roots are enclosed in a ball of soil with a burlap bag and wire basket around the ball. This is the more conventional approach to planting trees, but requires more digging (typically using heavy equipment) to move the trees due to the shear weight of the soil. Below is a photo of a red bud tree with the burlap and basket removed for planting.
Now that you can picture the difference between the two options, let's discuss the pros and cons of each.
Pros of Bare Root Planting
Can be planted by hand (very light)
Correct planting depth every time
Planted with a larger root mass intact
Quicker establishment of tree in relation to B&B
Cons of Bare Root Planting
Limit on available species of trees
Limit on size to 2” diameter trees
Pros of B&B Planting
No limit on trunk size of tree transplanted
No limit on available species of trees
Cons of B&B Planting
Heavy, often requiring equipment
Can be planted too deep
More expensive v. bare root
Majority of roots are removed
Root Growth an Important Consideration
The photos below highlight some of the important advantages and disadvantages of each planting method, focused particularly on differences in root growth between the two methods.
This photo above is the root system from a 3” caliper (trunk) swamp white oak that died the first year after transplant. Notice the tape around the trunk? That was the planting depth, you can see the root flare (where roots meet the trunk) was around 4 - 5” buried. Also notice how small the root system is (approximately 16” across) for a tree that large.
Compare the previous root system with the root system of the bare root tree below. This is a 2” sugar maple that was planted later that day. This root system is exceptionally wide and is not the norm, but it does show you just how many roots that swamp white oak that died above lost in the transplant process.
The last series of photos show the planting process when a B&B tree is planted too deep at the nursery. This series features a 5-6’ red bud I planted last spring on a playground. The first shot is of the root ball exposed and in the hole. The next one shows the trunk partially excavated to expose the root flare or proper planting height. The third photo has a 7-8” tall wire cutters in the shot to show you just how deep this tree was, the top of the wire cutters represents the original soil height and the bottom shows the final planting height.
I don't want to discourage people from buying B&B trees, but I do want to educate people on potential downfalls of getting a B&B tree and just “plopping” it in a hole. If you are contracting tree planting, make sure that the company knows how to plant trees correctly. Planting depth will dictate the long-term survivability and vitality of your tree.
I encourage people to consider bare root trees for their future planting projects. Either way you can’t go wrong planting trees, just make sure it's done correctly so the benefits will outlive us all.
Root Depth Affects Tree Health
Have you ever noticed a tree that looks like a pencil stuck in the ground while walking down the street? Here in Madison these trees are not hard to find, just try looking around next time you are out walking around.
But how many trees in the forest look like pencils stuck in the ground? None. They all have formidable root flares, where the trunk gets wide and meets the soil line. From that soil line to 12 inches down is where you will find most tree roots. The roots stay close to the surface in order to facilitate oxygen exchange essential for the tree’s survival.
Now imagine throwing a 6” layer of soil over the top of the forest floor, drastically cutting the oxygen supply to the trees. This is essentially what happens when we plant trees too deeply. Not only do we cut off most of the root system (to facilitate transport and planting) during the digging, now we stuck the tree in the ground too deep to get the necessary oxygen. Good luck arborlito, it's going to be tough!
The following discussion addresses planting depth and what to look for when you are doing it yourself or reviewing others' work. I have no problem looking over someone’s shoulder when we are talking about the future of our urban canopy. Please read this and other discussions on tree planting to get a full and comprehensive understanding of how to complete the task correctly. I’m trying to emphasize the most important step of planting here, planting depth.
How to Determine Proper Root Depth When Planting a Tree
When planting with b&b (balled and burlapped) or container sapling stock, the first step is to locate the root flare (where the trunk get wider, near the bottom). Don’t assume the root flare is just below the soil surface; I have found flares as deep as 8” below the soil line in some balled and burlaped trees! Once you locate the flare, dig your hole accordingly. Please remember not to dig too deep! If in doubt, err toward making the hole too shallow.
Carefully place the tree in the hole. We almost always remove the entire basket and burlap material, but this takes practice and care. If you want to remove everything, just make sure not to disturb the root ball, as you don’t want to loosen the soil around the roots. If the root ball is already pretty soft or loose, don’t take the basket off.
Now you are ready to skim off the excess soil to expose the root flare. I like to use tools intended for other purposes here. My favorite tool is hand pruners for peeling soil away, maybe because I always have one nearby. Be careful not to skim off the bark of the roots; you won’t kill the tree if you do some light damage, but no damage is, of course, ideal. If the soil is really hard and difficult to remove, try adding some water. Spraying SOME water might help loosen the soil a bit... at a minimum you will get really dirty and appear to be working hard!
Now you are ready to backfill the hole, making sure not to cover the flare with any soil or mulch. Put down a 2-4” layer of mulch around the tree, right up to the root flare. Continuous mulching, year after year, tends to build up around the trunk, so keep the flare clear of soil and mulch as time goes on.
Correct planting depth is crucial for long-term vitality and healthy trees. Planting trees too deeply leads to many issues, such as decreased growth rates, slower establishment after transplant, girdling roots, and ultimately a tree removal bill due to the shortened life span. Give your tree some flare, and your attention will be well rewarded. We think the tree looks better like that anyways!
The Autumn Blaze maple tree is a hybrid species comprised of half red maple and half silver maple. The combination has been popular for 20 years in commercial and residential plantings thanks to the combination of gorgeous fall color and rapid growth - exactly what homeowners are seeking. In addition, the Autumn Blaze is very hardy and can withstand a wide range of climatic conditions.
The big drawback of the Autumn Blaze maple is its structural weakness. The tree tends to crack easily at branch unions, which leads to broken branches and property damage after even mild storms. To avoid problems with Autumn Blaze maple trees, property owners must invest in regular tree care.
Maintaining autumn blaze maples requires regular pruning every 3 to 5 years. Regular pruning helps keep the structure of the tree sound and prevent some of the issues discussed/illustrated below. I planted an Autumn Blaze at my parent’s house 15 years ago and I prune it every year! My dad is always amazed at how much wood I remove from the tree on a yearly basis.
The two major maintenance issues for this tree deal with the roots and the canopy. For a discussion on roots and root zones check out some of our other blogs related to that topic. We will discuss canopy management below.
Canopy Maintenance Prevents Broken Branches
If an Autumn Blaze maple tree has been in your landscape for more than five to tens years without any structural or upper canopy pruning, please contact a certified arborist ASAP because these trees require regular pruning. I’m not exaggerating here, they really do need regular care in order to stay in your landscape long-term. Unmaintained trees develop weak branch attachments (cracks) prone to failure, which ultimately can mean losing the entire tree.
This blog features a 14” diameter Autumn Blaze maple that has been growing for 15+ years (see below photos). Since the upper canopy has never been pruned, all its major branch unions (where they connect to the trunk) have developed significant cracks due to included bark. Included bark is bark wedged between a v-shaped branch union of co-dominant stems. In the photos above, the lower branches have strong open unions, while the upper branches that look like v's have included bark. These are branches are most susceptible to high-wind branch failure, also know as sail effect. So this tree needs some extra TLC in the form of dynamic support cables. The cables provide extra support for the weak v-shaped branch unions that are synonymous with Autumn Blaze maple trees.
Reduction Cuts Reduce Canopy Load
With this particular tree we will reduce (shorten) branches competing with the central trunk in order to encourage the central trunk or leader to assume the dominant position in the tree (see below photos). By reducing competing leaders you minimize the risk of branch failure and redirect energy from those branches by removing live tissue.
Dynamic Support Cables
This tree is very consistent in terms of (poor) form; without regular pruning from the time of planting it is almost certain to have structural problems. Because this tree had not been previously pruned, it requires more than just pruning; dynamic support cables will be necessary to provide extra support for the weak unions described above. These support cables are permanent fixtures in the tree. Please read Support Systems for more information on dynamic cabling.
The dynamic cables are placed in the upper canopy and are not very noticeable from the ground. They will provide added support for the tree making it more likely to withstand heavy weather events throughout the year. Now that the tree is pruned and the cables are installed it you can enjoy its ever-expanding shade and wonderful fall color.
Trees are amazing living things, but they grow and thrive on simple principals. Understand and proactively promote your trees’ health via 3 easy steps.
Customers ask often about what they can do with trees they have asked us to remove from their property. If you must take a tree down on your property, you often can make use of the wood by choosing one of a number of recycling options. Consider the following:
If you are a woodworker, or you have a close friend or family member who is, you won't have to think twice about what to do with a felled tree... you'll turn it into something beautiful, of course! But not everyone has the equipment or wherewithal to cut down, mill, and work large sections of wood into furniture, so we like to promote a local non-profit that can help.
Wisconsin Urban Wood is a Madison-based non-profit that connects property owners with salvageable wood with woodworkers who love recycling urban timber to make furniture or other goods. In this way, you can make sure you keep some of your cherished tree in your home as a chair, desk, table, or other piece of furniture, or allow someone else to have the same.
The tree pictured below serves as a prime example of a tree destined for a long second life. In the hands of local woodworkers and artisans, this tree will be turned into beautiful furniture and/or custom finishing wood. The branch union (where the trunk splits) can often be used to make interesting desks or other furniture, while the main trunk is often milled for flooring, boards, or other "straight" uses.
You or someone you know might enjoy using your felled tree as firewood. Firewood. The one major caveat to keeping firewood is to make sure the firewood does not harbor any contageous diseases that could infect remaining trees in your landscape. Some common diseases to be careful of are oak wilt and Dutch elm disease. If you do keep diseased wood, make sure to split all the wood and remove the bark. In some cases (as with oak wilt and Dutch elm disease) you may need to seal the wood pile for a season so the bugs that carry the fungus die in the wood pile and don't transmit the disease your living trees. Always make sure to know where your wood is coming from, especially green firewood (has not been dried or split).
NOTE: Dane County wood is under quarantine due to Emerald Ash Borer, so firewood should not travel more than 10-15 mies, if at all. Please do NOT transport wood from your Dane County home to a vacation home or campground up north, as you may bring EAB along with you!
If you or a neighbor would like woodchips for landscaping, we can leave a pile on your property from the wood we remove.
