Question 1

When is the best time to prune my apple and fruit trees?

Accepted Answer

The best time to prune apple and most other deciduous fruit trees is late winter to early spring — while the tree is dormant but before buds break roughly February through March in the upper Midwest, later north, earlier south. Why dormant pruning is ideal: - The branch structure is clearly visible without leaves - The tree isn't actively growing, so pruning wounds close efficiently as spring growth begins - Lower disease pressure than summer cuts - You can shape for sunlight penetration and air

Question 2

How do I prune a crape myrtle without committing "crape murder"?

Accepted Answer

"Crape murder" is the all-too-common practice of topping crape myrtles into ugly stubs each year. It's unnecessary and harmful — proper crape myrtle pruning is light and preserves the plant's beautiful natural form. Why topping is bad: - It produces a cluster of weak, spindly shoots from each cut, which flop under the weight of flowers - It creates knuckle-like scars and ruins the graceful branching habit - It does not make the plant healthier or bloom more — crape myrtles bloom on new growth re

Question 3

When can I safely prune my oak trees in Wisconsin?

Accepted Answer

In Wisconsin and throughout the Upper Midwest, the timing of oak pruning is critical because of oak wilt disease. The sap beetles Nitidulidae that spread the oak wilt fungus are most active during warm months, and they're attracted to fresh pruning wounds. Safe pruning window for oaks in Wisconsin: - November 1 through March 31 — this is the recommended safe pruning period when sap beetles are inactive - The Wisconsin DNR strongly advises against pruning oaks from April through October - Even du

Question 4

How much of my maple tree can I prune at once?

Accepted Answer

The general rule of thumb is to never remove more than 25% of a tree's canopy in a single growing season. For maples specifically, being more conservative — around 15-20% — is often advisable because maples are particularly prone to stress responses from heavy pruning. Why over-pruning is harmful: - Leaves are the tree's food factory. Removing too many reduces the tree's ability to photosynthesize and produce energy. - Heavy pruning triggers a flush of epicormic growth water sprouts — weakly att

Question 5

Should I seal or paint over pruning cuts on my trees?

Accepted Answer

This is one of the most common tree care myths. In most cases, NO — you should not apply wound sealant, tree paint, or pruning paste to cuts. Research conducted over the past 40+ years by Dr. Alex Shigo and others has conclusively shown that wound dressings do more harm than good. Why wound sealant is usually bad: - Trees compartmentalize wounds naturally through a process called CODIT Compartmentalization of Decay in Trees — they wall off damaged tissue rather than "healing" like animals do - W

Question 6

Can I prune dead branches off my tree at any time of year?

Accepted Answer

Yes — dead branches can and should be removed at any time of year. Since the wood is already dead, the timing restrictions that apply to live-wood pruning don't apply. In fact, removing dead branches promptly is a safety and tree health priority. Why prompt removal matters: - Dead branches are hazards — they can fall unpredictably, especially during storms, posing risks to people and property - Dead wood serves as an entry point for decay fungi that can spread into healthy tissue - Removing dead
