Your trees should enhance your property, not create problems. Unfortunately, bad tree trimming and bad tree pruning are more common than people think. Whether it’s cutting too much, using the wrong technique, or trimming at the wrong time of year, these mistakes can turn a healthy tree into a liability.
In this guide, we’ll explain how to avoid bad pruning cuts, understand the difference between tree trimming and pruning, explore the types of tree trimming, and offer tips on how to fix pruning mistakes, all to keep your trees beautiful and your property safe.
Proper tree trimming techniques, such as the three-cut method and crown thinning, promote healthy growth and prevent damage. Common mistakes, such as over-pruning, topping, or cutting in the wrong season, can harm your tree's structure and health. Knowing what to do (and what not to do) is key to keeping trees safe and beautiful.
One of the biggest mistakes is pruning during summer heat. Most trees are already stressed from dry conditions and high temperatures, and cutting into them now increases the risk of sunburn, disease, and slow recovery.
While a few species (like Juniper) tolerate tree trimming sessions in summer, most do better in late spring or winter. If you’re not sure when to prune your specific tree, don’t guess. Timing matters, and it’s often worth talking to a professional for clarity.
Pruning too much can weaken a tree dramatically. The general rule? Never remove more than 10 to 15% of a tree’s canopy at one time.
When you over-prune, you strip away the tree’s food-making ability, cause imbalance, and slow down healing. The tree may respond with erratic growth, dead limbs, or stunted development. If your tree looks lopsided or bare, there’s a good chance you’ve gone too far.
Using dull or dirty tools can leave ragged cuts that don't heal properly. Worse, they can introduce disease into the tree. One of the best ways to avoid bad pruning cuts is to use the three-cut method:
A small undercut prevents bark tearing.
A top cut removes the limb’s weight.
A final clean cut at the branch collar encourages natural healing.
Bad cuts aren’t just unattractive; they can weaken the tree permanently and invite decay. Show your trees some love and don't let this happen to them.
Many homeowners ask, “Can you top a tree without killing it?” Technically, yes, but it’s rarely a good idea. Topping removes the main canopy, leading to weak regrowth and vulnerability to disease and pests. Instead, crown reduction offers a healthier alternative that controls height and spread without destroying the tree’s natural structure.
We strongly discourage topping unless necessary, and if it is, it should be done by someone trained in tree topping tips and safety protocols.
Cutting a surface root that’s cracking your walkway might seem harmless, but root pruning is tricky. Cutting the wrong root can destabilize the entire tree, making it unsafe.
Cutting tree roots without killing the tree requires precise technique and knowledge of the tree's root system. In most cases, this is best left to a certified arborist.
Many people use the terms interchangeably, but tree trimming vs cutting comes down to intent. We've broken down the definitions so that they're easy to compare and contrast.
Both are important, but knowing when and how to apply each technique is key to longevity. That's why having an expert team by your side helps make these calls.
Different trees and goals call for different approaches. Understanding the types of tree pruning helps avoid costly mistakes. Let's take a look at the different types below:
Using the right type of trim or pruning, especially when timed well, helps the tree grow strong, balanced, and safe. Our team is ready to make the call on what sort of tree trimming or pruning your trees need.
If your tree has been over-pruned or poorly cut, don’t panic. Trees are resilient, and here’s what to do:

Do you have questions about tree pruning and trimming? Our FAQs break down everything you need to know, from the difference between trimming and pruning to when not to cut and how to fix common mistakes. Whether you're maintaining tree health or managing overgrowth, smart cuts lead to stronger, safer, and better-looking trees.
Bad techniques include removing too much at once, making flush cuts, trimming during hot or dry seasons, or using dull, unsanitized tools. These can stress the tree, leave open wounds susceptible to disease, or create long-term structural problems. Proper technique and timing are key to preserving tree health.
Examples include topping the tree (removing the main canopy), cutting into the branch collar, or stripping too many limbs from one side. These mistakes disrupt the tree’s natural growth pattern and can lead to decay, pest infestations, or lopsided regrowth that weakens stability.
To correct over-pruning or poor cuts, stop further trimming and support the tree’s recovery with regular watering, light fertilization, and mulching. Avoid additional stress, like soil compaction. In some cases, a certified arborist can reshape the tree gradually over several seasons.
Avoid pruning during early spring and summer when trees are actively growing. This is when they’re most vulnerable to pests, moisture loss, and disease. Trees heal more efficiently when pruned during dormancy in late fall or winter, depending on the species.
Recovery time depends on the tree species, age, and the extent of pruning. Light trimming may take one season to bounce back, while recovery from major pruning could take several years. With the right care, most healthy trees will restore themselves over time.
