As the temperature drops and the snow settles across Wisconsin, yard work is likely the last thing on your mind. However, if you are looking to maintain a healthy, safe, and beautiful landscape, the dormant season — specifically late winter — is actually the best time to prune your trees and shrubs.

While it might seem counterintuitive to cut back branches when everything looks dead, "dormant pruning" sets your landscape up for success when spring finally arrives.

Why Prune in the Winter?

According to the experts at the Chicago Botanic Garden, heavy pruning should be performed when the tree is dormant, preferably in late winter before active growth begins.

Here is why we recommend scheduling your pruning services now rather than waiting for the green leaves of spring:

1. Disease Prevention

One of the biggest risks of pruning during the growing season is the spread of disease. Fresh cuts on a tree can attract insects that carry harmful fungi and bacteria.

Oak Wilt & Dutch Elm Disease: These serious diseases are spread by beetles that are active in spring and summer. Pruning in winter, when these pests are inactive, significantly reduces the risk of infection.

2. Better Visibility

It is much easier to see the "skeleton" of a tree when it is naked. Without lush foliage blocking the view, we can easily identify:

Dead, diseased, or damaging wood.
Crossing branches that are rubbing against each other.
Structural issues that could become hazards in a storm.

3. Less Stress on the Plant

Pruning acts as a shock to the system. Doing it while the plant is "sleeping" (dormant) minimizes this stress. Additionally, the wounds from the cuts will heal much faster once the plant’s energy surges in the spring.

Note: Certain trees like Maples bleed sap heavily if pruned while active. Winter pruning avoids this messy problem.

The Hidden Security Risk: Unruly Vegetation

Beyond the health of the plants, winter pruning is essential for the safety and security of your home or business. Overgrown vegetation is more than just an eyesore—it can be a security vulnerability.

Blocked Security Cameras: A single wind-blown branch can obscure the lens of your security cameras, rendering them useless. Even if it doesn't block the view, moving branches can constantly trigger motion recording, filling your storage with hours of "footage of a tree."
Interference with Motion Sensors: Overgrown shrubs can block the field of view for motion-detected floodlights and alarm sensors. If the sensor can’t "see" the intruder because of a wayward branch, your lights won’t turn on.

Taking care of your trees and shrubs now ensures they will be lush, healthy, and structurally sound when the warm weather returns.
