For most trees in Tennessee, the best time to prune is the dormant season, from late fall through late winter. But there are important exceptions, and dangerous limbs should come off whenever you find them.
Why winter works best
- You can see the structure. With the leaves gone, it’s easy to spot dead, crossing and weak branches.
- Less disease and insect risk. Fewer insects are active to find fresh cuts.
- Faster recovery. The tree seals its wounds quickly once growth starts in spring.
- Easier scheduling. Crews around Chattanooga are often less busy in winter than in spring storm season.
Oaks: avoid spring and early summer
Oak wilt is present in Tennessee. The fungus is spread by sap beetles drawn to fresh pruning wounds, and they’re most active from spring through midsummer. Avoid pruning oaks during that window unless a limb is broken or dangerous. Winter is the safest time for oaks.
Flowering trees: prune after they bloom
Dogwoods, redbuds, azaleas and other spring bloomers set their flower buds the year before. Prune them right after they finish flowering, or you’ll cut off next year’s blooms.
Maples and birches: expect some sap
Maples and birches bleed sap when pruned in late winter. It looks alarming but doesn’t hurt the tree. If it bothers you, prune them in early summer once the leaves are fully out.
Times to avoid
Early fall. Heavy pruning in late summer and early fall can push new growth that doesn’t harden off before the first frost.
During drought. Trees stressed by a hot, dry Chattanooga summer don’t need the extra stress of heavy pruning. Wait for rain.
Any time of year
Dead, broken or hanging limbs over the house, driveway or a play area should come off whenever you notice them, regardless of season. So should limbs damaged in a storm.
Plan ahead for storm season
Chattanooga’s strongest storms usually come in spring. Having heavy limbs over the house reduced in winter is the cheapest way to avoid an emergency call later. Call (423) 275-4820 for a free written estimate on tree trimming.
