INTRODUCTION: Have you ever wondered, “What is the proper way to plant a tree?” and does it really matter?

Sometimes, it’s hard to imagine the “future tree” it has the potential to become, for example, how tall it will grow, how much shade it will produce, etc.

It’s kind of like buying a cute little puppy. It’s small, -doesn’t take up much room, and did we mention it’s cute?!! Before you realize it, it becomes a larger dog that eats more, poops more, and takes up more space. You still love your dog, but over time, your responsibilities in maintaining your pet have increased. You do more things to keep it happy, well-fed, healthy, and comfortable. Similarly, the change over time in addressing the needs of your trees will grow!

If you are thinking about planting one (or more) trees, how will you keep them “happy, well-fed, healthy, and comfortable?”

After removing excess soil around the trunk and checking for girdling roots, the rootball transport materials (twine, upper third to half of burlap and wire basket) are removed.

First, you have to plan for it! Why do you want to plant a tree? Are you planting it yourself, with family or friends, or for-hire? Have you had the soil tested? What kind of tree do you want? Are nearby utility lines a concern? From where will you purchase it? When is the best time to plant a tree? (See “Planting New Trees – Spring, Fall, or When?”) How much space is available for one? Will it hide your property as a natural barrier (a.k.a., privacy fence)? Will it kill your lawn from too much shade? Will you have time to care for its needs properly? Etc.

Yes… There is much to consider before planting a tree, but don’t let that stop you or discourage your desire to own one! Just keep in mind that for the best success in owning a tree and maximizing your enjoyment for decades to come, they do require your attention at times while doing their thing. Take some time to learn about them and seek expert advice before spending your hard-earned cash. Not every tree will grow well in every location. There’s a ‘right tree for the right place!’

 


 

BEFORE, DURING, and AFTER TREE PLANTING

We’ve put together a list of reminders on what we believe to be the most important things that MUST happen to provide a new tree the best chance for a long, productive life in its new home:

SOIL TESTING:

If you haven’t done so already, get a soil test FIRST to get an overview of your planting site’s soil condition. Even native trees can struggle in the wrong soil conditions. (See list of Indiana trees that tolerate high alkaline soil.)

Typically, when we order a soil analysis, we ask the laboratory to test for the following things: organic matter, available Phosphorus, exchangeable Potassium, Magnesium, Calcium, soil pH, buffer pH, cation exchange capacity (CEC), percent base saturation of cation element, soluble salts and Sodium, along with Sulfur, Zinc, Manganese, Iron, Copper, and Boron

 

While we may not need to use all of this data in every planting instance, it’s good data to have on hand. Our focus is primarily on existing trees on a property and potential new tree plantings, not necessarily the turfgrass. (We leave that to the lawn care guys!😉) However, it works in the best interests of the property owner and their trees when arborists and lawn care providers work in harmony with each other to avoid misaligned treatments!

 

LOCATION, LOCATION, LOCATION:

Choose locations on your property that are suitable for new trees. These planting sites should provide adequate sunlight and space before planting.

VERY IMPORTANT: You’ve probably heard or seen the expression, “Right tree, right place.” Before setting your heart on a tree species, be sure that it will be small enough or large enough for the site you wish to plant it into. Always research a tree’s growth potential statistics. How tall could this species get? How wide? Is it prone to surface roots? etc. Avoid trees that could grow tall enough to affect overhead power lines or that could obstruct traffic signs or block utility access points and right-of-ways. The wrong tree planted in the wrong place will likely result in conflicts and extra expenses for you in the future, including removal.

TREE SELECTION:

With your soil test results in hand and an ideal planting spot picked out, select a tree species that should do well at that location. In addition to knowing the soil condition, you need to be aware of your site’s USDA Hardiness Zone (if in Indiana, see the Indiana Hardiness Zone map). They are a guide to which trees can survive your area’s minimum winter temperatures. Choosing a tree within your zone ensures it has the necessary winter hardiness to withstand the cold, preventing damage or death. Conversely, selecting a tree from a zone with colder minimums than your own could lead to winter injury or failure.

Also, try to find a species or a species cultivar that shows natural resistance to pests and diseases. the term “resistant” should not be confused with the word “immune” because they are not the same thing. A tree that has resistance to a particular disease, for example, may last longer and potentially avoid getting ill as opposed to another tree of that same species that is more susceptible, but complete immunity can not be guaranteed. All transplanted trees will usually require some form of care and maintenance at some point in their life. Try to select a species that best fits your location and will meet your target maintenance goals and budget.

Be sure to inspect candidate trees before purchasing them to avoid receiving defective or poorly structured trees. The likelihood of higher maintenance is increased substantially by purchasing and planting a tree that already has significant defects or a problematic structure. Some dealers may try to sell you on a tree by calling their defects “unique” or saying it gives the tree “character,” but beware! True, it does offer uniqueness, but just like a topiary pruned shrub, it will require diligence and dedication to maintain and preserve that “character” you so love. Therefore, use caution. Never blindly buy a tree! Inspect it first or have a qualified arborist inspect it for you.

AVOID PURCHASING INVASIVE SPECIES!!! Purchasing invasive trees is detrimental because they damage local ecosystems, cause economic harm, and may create long-term problems for your own property. These non-native species outcompete native plants for resources and disrupt the food web, negatively impacting wildlife.

 

PROPER PLANTING:

Plant the tree properly. This should go without saying, but this basic principle is often neglected even by self-claimed “professionals.” It’s not simply a matter of digging a hole and plopping your new tree into the ground. You’ll witness this happen regularly in new residential and commercial developments. Frequently, specific preparation steps for the tree, including rootball inspection & preparation and digging a planting hole at the proper depth & width, are disregarded and skipped. This happens a lot when companies competitively underbid for a planting job, or the property owner doesn’t understand, nor appreciate, the importance of planting a tree properly, or doesn’t want to pay for the extra time and effort to have it planted correctly. This mindset, however, is short-sighted and puts the tree’s longevity at risk. You typically only get one shot at planting a tree correctly! If you skip tree preparation, you may regret it later when preventable problems become apparent years down the road that can’t be fixed. Trees are miraculously designed to adapt, but a poorly planted or sickly tree is more likely to decline and die sooner, eventually breaking down and returning to enrich the soil as food for other plants and organisms. Therefore, if you are planting your new tree with the purpose of it dying prematurely and becoming compost, then this advice on planting it properly for long-term enjoyment won’t apply to you.

Key steps to successful tree planting.

New trees may find it challenging to establish roots in highly compacted soil. Widening your planting hole may be necessary to reduce soil compaction when you backfill the hole.

Planting in Compacted Soil will require excavating a wider hole. Break up the backfill soil to make it less compacted and encourage root establishment.

 

GOOD CULTURAL PRACTICES:

Ensure the tree will be properly cared for to help them overcome transplant shock and establish strong roots. There are A LOT of initiatives to “Save the World” by planting a gazillion trees, but who’s taking care of them? Intending to save costs, the budgets allocated for these ‘green initiatives’ typically only pay for the trees and are planted by volunteer workers. Many of these events omit a program to manage ongoing care after the planting event. As a result, these trees are often not properly managed. Just take a drive and see the dying/dead trees that were planted en masse in prior years during a special Earth Day or Arbor Day celebration or following a widely-publicized urban canopy restoration initiative. Relying on the public, particularly in local impoverished neighborhoods, to care for such trees doesn’t always work out. So, on your property, if you desire to plant new trees that are successful, you will have to plan for their care and use good cultural practices. These practices are fundamental to the tree’s health and survival and are often necessary during the first three years of growth.

 

What do these practices include?

    • WATERING YOUR TREES ADEQUATELY: For one, trees need sufficient water to survive. It’s a basic, but an essential requirement.
    • MULCHING AROUND YOUR TREES PROPERLY: Trees also need to be protected from mechanical injuries such as mower damage, weed-trimmer damage, etc. This is a common problem that a few lawn mowing professionals neglect to give proper attention to. As far as landscape aesthetics go, if mulch is to be put around your trees it needs to be applied properly to benefit not just “curb appeal” but more importantly, plant health. (If you are unfamiliar with what proper mulching means and why that is important, then consider this a polite wake-up call.)
    • PRUNING YOUR TREES PROPERLY: Trees may eventually need some maintenance pruning. However, if pruning is not done properly, it can ruin a tree for life. Bad cuts and even tree topping are constantly being committed by individuals and small businesses who genuinely don’t recognize the harm done to trees, or they top trees deliberately and try to downplay the harm to trees. Hint: Science, research, studies, and evidence prove that trees don’t respond well to being topped and never will.
    • SUPPLEMENTING WITH VITAL NUTRIENTS, AS NEEDED: Occasionally, poor soil conditions may require you to intervene and provide your trees with supplemental nutrients. Use your soil test results to guide you or your arborist in selecting appropriate fertilizers to restore vigor and health to your trees.
    • MANAGING PESTS AND DISEASES: Addressing pests, particularly exotic pests, and diseases that harm the health and vigor of your trees must be managed. Some trees are more susceptible than others, and it may depend on the species on what problems they may face in the future, and the potential of how detrimental problems could become. Still, when life-threatening health issues arise, these must be addressed promptly, usually with the aid of a qualified, trained & experienced professional. Keep in mind that these professionals are not gods, and there are some diseases that scientific research has yet to cure. Dure or not, ALL trees will eventually die over time from any number of reasons, some undetectable.
Happy planting, and may your efforts prove successful!

 


WHAT TREES CAN I PLANT? [in Indiana]

Alkaline (High Soil pH) Tolerant Trees

Here is a list of trees that have shown tolerance to higher soil pH in Indiana, listed alphabetically (by Latin Name).
Note: We first highly recommend getting a soil test (soil analysis) performed by a reputable laboratory.
Native (Indiana) Species (Non-invasive)
(For a general list of Indiana native species that includes links for more information on each tree listed below, click TREE-search.

    • Ginkgo (Ginkgo biloba)
    • Black Spruce (Picea mariana)
    • Silver Linden (Tilia tomentosa)

 Trees to AVOID

High soil pH, especially in limestone-rich areas of Indiana, can cause iron and manganese to become chemically unavailable to plants. This can lead to visible problems, most commonly chlorosis, which is the yellowing of leaves and needles, particularly noticeable in the spring. Without the ability to take up these essential nutrients, the trees may experience stunting and poor overall health. (There may exist hybrid cultivars that are more tolerant of high pH soils. Please consult with your nursery representative to see if they stock any such varieties.)
    • Firs (Abies spp.)
    • Red Maple (Acer rubrum) requires more acidic conditions than what is typical in Indiana, and high pH can impact its growth, also beware of the Asian Longhorn Beetle! (Update: Redpointe Red Maple (Acer rubrum ‘Frank Jr.’ PP 16769) appears to do fairly well in high pH soils, and so this may be a welcome exception to the rule of ‘trees to avoid’. See more info about this introduced variety here.)
    • River Birch (Betula nigra), but beware of Asian Longhorn Beetle!
    • Dogwood (Cornus spp.)
    • American Sweetgum (Liquidambar styraciflua)
    • Spruces (Picea spp.)
    • Pines (Pinus spp.), especially white and yellow pines, require a pH of 5.2 to 6.0 and will show signs of stress, like yellowing needles, in higher pH soils
    • Pin Oak (Quercus palustris) is often cited as a species that struggles in high pH soils
    • Bald Cypress (Taxodium distichum)
    • Hemlock (Tsuga)

One more thing before you plant that new tree in Indiana…

Call before you dig!

DON’T TAKE CHANCES! Call 8-1-1 BEFORE you dig!

Knowing where underground utility lines are buried before each digging project begins helps to prevent injury, expense, and penalties. The depth of utility lines may vary, and multiple utility lines may exist in one area. Simple digging jobs can damage utility lines and disrupt vital services to an entire neighborhood, harm those who dig, and result in expensive fines and repair costs. Marked lines show those who dig the approximate location of underground lines and help prevent undesired consequences.
