Tree Trimming Basics: Topping Versus Crown Reduction

Overgrown trees create all sorts of problems on your property. The branches may interfere with power lines, scrape against your house, or crowd out all the sunlight from the yard. When the problem is an overly large tree with a too-big canopy, then you usually only have two options for controlling the size: topping or crown reduction.
Topping
Tree topping, sometimes called heading, creates a flat-topped tree because all of the vertical branches are removed in order to reduce the height of the tree.
Method
The method is straightforward: cut off all the lateral branches above a certain height so that the canopy isn't too tall. Sometimes, the lateral branches are also cut back to a prescribed length to further control the canopy.
Topped trees have an obvious flat top that many people find unattractive. In some cases, only part of the canopy may get topped, such as only on the side that has grown into the power lines.
Concerns
A topped tree has an unnatural form that can lead to several health and structural concerns. Scrubby, weak growth can result along topped branches as the tree tries to recover the lost foliage.
Topped trees can also collect heavy snow or ice loads in winter, which increases the chances of branch breakage or trunk splitting. Sun damage due to a too-thin canopy and insect infestations can also plague topped trees.
Considerations
You only have a few reasons to top a tree, since the negatives far outweigh any positives. The only exceptions are trees that can be trimmed into formal hedges, such as some evergreen trees. Even then, a slightly rounded or sloped top is preferred to a flat top that collects snow and moisture.
Further, when topping formally pruned shrubs, ensure the bottom is wider than the top so sun and moisture can reach the lower branches.
Crown Reduction
Crown reduction takes a more cautious approach than topping. Branches are selectively cut to reduce the overall size and density of the canopy.
Method
Crown reduction methods require assessing the length, position, and health of every main lateral and vertical branch in the canopy. Branches are then selectively cut back, typically by no more than a third of their length, to help control the shape and size of the canopy. Cuts are made near buds so that the ends of the branches leaf out, which helps prevent sun-scald on the newly cut branch tips.
Some interior branches are also removed to help open up the canopy so sunlight can filter in and to allow for air circulation. Generally crowded branches and those that are weak or damaged are chosen for interior reduction pruning.
Concerns
Most concerns center on how well the species of tree reacts to extensive pruning. Some species are more prone to rot or stress from cutting. Your tree service can alert you to which species shouldn't be extensively pruned in your area.
Trees can recover in a season or two from reduction pruning, so this type of pruning is an ongoing process that must be completed annually for the life of the tree.
Considerations
Consider crown reduction for any tree that can handle extensive pruning and that has grown larger than desired. Mature trees can benefit from reduction pruning, but the best method is to start when the tree is still young. The younger the tree when you begin reduction pruning, the fewer cuts that will need to be made as the tree matures since the canopy won't have a chance to become overgrown.
The best way to manage tree height is two-fold: create an annual pruning plan and stick to it, and only plant tree varieties with mature sizes that fit the planting site. If you do need to consider topping or crown reduction, contact a professional service like Baumann Tree for help.

A tree does not have to be falling over to become a concern. Sometimes the first warning is a branch scraping the roof. Other times, it is a canopy that has grown so thick it overwhelms the yard, a limb hanging above the driveway, or a tree that simply does not look as healthy as it did a few years ago. Knowing when a tree needs attention can help St. Louis property owners address problems before they become much harder to manage. Baumann Tree provides tree service, tree removal, and tree trimming in St. Louis, MO for homeowners and property owners who want to take care of troublesome trees safely and effectively. For professional tree care, call 636-375-2812. When Your Trees Start Competing With Your Property Trees and homes share the same space, and eventually that can create conflicts. A tree that was small when a home was built may now stretch across the roof, crowd a fence, block a driveway, or extend branches toward neighboring property. Mature trees can be one of the best features of a St. Louis yard, but they also require more attention as they grow. Professional tree service in St. Louis, MO can help you determine what needs to be trimmed, what should be monitored, and when removal may be the better long-term solution. Instead of treating every tree the same way, Baumann Tree can evaluate the situation and recommend an appropriate approach for the property. A Tree Doesn't Have to Be Dead to Need Removal Many people associate tree removal with completely dead trees, but there are other reasons a tree may need to come down. Its location may have become problematic, the trunk may have developed structural weakness, storm damage may have compromised major limbs, or the tree may be declining to the point that keeping it creates an unnecessary risk. With tree removal in St. Louis, MO , the surroundings matter just as much as the tree itself. Homes, garages, fences, landscaping, sidewalks, and neighboring properties can all affect how a tree should be removed. Baumann Tree can assess the tree and surrounding area before determining how to approach the job. Warning signs worth paying attention to include a new or increasing lean, large dead sections in the canopy, cracks in major limbs or the trunk, decay, broken branches that remain lodged in the tree, or noticeable changes following severe weather. If a tree on your property has you wondering whether it is still safe to keep, call 636-375-2812 and have Baumann Tree take a closer look. Tree Trimming Is About More Than Making a Tree Look Neat Trimming can dramatically change the appearance of a property, but good tree trimming should accomplish more than creating a tidy canopy. Strategic trimming can remove problematic branches, create clearance around structures, address damaged growth, and help prevent certain limbs from becoming larger concerns later. For example, you may need tree trimming in St. Louis, MO if branches are beginning to hang over your roof, interfere with a driveway or walkway, rub against one another, block visibility, or create too much weight in a particular part of the canopy. The goal is not simply to cut branches back. Trees respond to pruning, which is why knowing which branches to remove—and which ones to leave—is important. Professional trimming helps address the immediate issue while taking the overall tree into consideration. Take Another Look After a St. Louis Storm Take Another Look After a St. Louis Storm Strong winds and thunderstorms can reveal weaknesses that were easy to miss beforehand. After severe weather, take a look at the trees around your home from a safe distance. A branch may be partially broken without falling, the canopy may look noticeably different, or a tree may appear to be leaning more than it did before the storm. Damage high in the canopy can also be difficult to judge from the ground. If something looks different, having it evaluated can be a much better option than waiting to see what happens during the next round of bad weather. Give Your Trees the Attention They Need Call a certified arborist promptly if you notice sudden canopy dieback from the top down, D-shaped holes in ash bark, wilting spreading across connected trees, dark streaking under oak bark, or shepherd's crook tips on ornamental pears or crabapples. Even when symptoms seem minor, a professional inspection is worthwhile. Most tree pests target stressed trees first, making consistent care essential to prevention.
