When & Why to Prune Trees in Late Spring

Many people think spring pruning ends in March—but that’s not always the case.

In late spring (May–early June), there’s still plenty you can do to improve tree structure, remove hazards, and keep ornamentals in great shape—as long as you know what to prune and when.

1️⃣ Trees You Can Still Prune in Late Spring

Not all trees respond the same way to pruning. Late spring is a good time to:

✂️ Remove dead or damaged wood missed earlier 🌿 Clean up ornamental shrubs like viburnum or lilac after they bloom 🛡 Thin interior branches to improve airflow and reduce pest risk 🌳 Train young trees to build good structure

💡 Avoid heavy pruning on stressed trees or species that bleed sap (like maples or birches).

2️⃣ Why Prune After Bloom?

Shrubs like forsythia, lilac, and viburnum bloom on last year’s growth. Pruning them after flowering helps:

✔ Preserve flower display ✔ Shape the plant before summer growth ✔ Prevent overcrowding next season

3️⃣ Late Spring Pruning for Health & Safety

It’s also a smart time to check for:

• Hanging or broken limbs

• Branches interfering with structures or walkways

• Overcrowded interior growth on ornamentals

Selective pruning helps reduce storm damage risk and keeps your landscape clean and manageable.

🌿 Final Thoughts

You don’t need to wait until fall—or rush to prune in February. If it’s done carefully, late spring pruning is a great tool to keep trees healthy, balanced, and beautiful.
