Spring Tree Care: What to Do in March

March on Long Island is a critical time for your trees. The ground is thawing, buds are forming, and the growing season is just around the corner. Here's what you should be doing right now to set your trees up for a healthy year.

1. Inspect Your Trees for Winter Damage

Walk your property and look up. Winter storms can leave cracked branches, split trunks, and hanging limbs that are dangerous. Look for branches that are broken but still attached — these "hangers" can fall without warning. If you see damage high in the canopy, call a professional. Don't try to climb up there yourself.

2. Prune Before the Leaves Come In

Late winter and early spring — right now — is the best time to prune most deciduous trees. Without leaves, you can see the branch structure clearly. Pruning now promotes strong spring growth and reduces the risk of disease, since most fungal spores aren't active yet. Focus on removing dead wood, crossing branches, and any limbs that are rubbing against each other.

3. Mulch Your Trees (the Right Way)

A 2-3 inch layer of organic mulch around the base of your trees helps retain moisture, regulate soil temperature, and suppress weeds. But don't pile it against the trunk — that's called "volcano mulching" and it causes rot. Keep mulch 3-4 inches away from the trunk and spread it out to the drip line.

4. Check for Signs of Disease

Look for cankers (sunken, discolored areas on bark), fungal growth like shelf mushrooms at the base, and oozing sap. These can indicate serious problems. Early detection is key — many tree diseases can be managed if caught early, but become fatal if ignored.

5. Plan Any Removals Now

If you have a tree that needs to come down, spring is the time to schedule it. The ground is firm, access is easier without full foliage, and you'll beat the busy summer season. Plus, removing a dead or dying tree before hurricane season protects your home and family.
