Pecan Tree Care in Tallahassee, FL

Pecans are Big Bend heritage. The old homesteads across Leon and Jefferson counties — Monticello styles itself pecan country for a reason — planted them a century ago, and the trees are still here: 80-foot giants shading half a backyard, still throwing nuts in the good years. In the deep red-clay and alluvial soils north and east of town, a healthy pecan can outlive everyone who ever picked under it.

They’re also, of all the big trees in Tallahassee yards, the one that earns the most mixed feelings. Pecan wood is brittle. The classic old-tree architecture — two or three massive co-dominant trunks with included bark in the crotch — is exactly the structure that fails in summer thunderstorms. And the species hosts a full cast of harmless-but-annoying tenants: scab fungus, honeydew-dripping aphids, webworms, and squirrels running a full-time nut heist. Knowing which problems are cosmetic, which are cultural, and which are structural is the whole art of pecan care here.

The annual pecan complaints — and what they actually mean

August leaf drop: pecan scab

A pecan raining blackened leaves in late summer almost always has scab — the fungal disease that defines pecan growing in the humid South. On susceptible old varieties it strips foliage and blackens shucks in every wet year. Orchards fight it with spray towers; that’s not realistic over a house, so residential management is cultural: rake and dispose of infected leaves and shucks, thin the canopy for airflow, and accept that an old susceptible tree will have ugly late summers. It stresses the tree over decades rather than killing it outright — and if you ever replant, scab-resistant cultivars like Elliott, Sumner, and Caddo make the whole problem optional.

June drip: aphid honeydew

The sticky film on cars and patios under a pecan is honeydew from black-margined and yellow pecan aphids feeding overhead — followed shortly by black sooty mold growing on the sugar. It looks terrible and hurts almost nothing. Where the mess is intolerable, a properly timed systemic treatment gives season-long control; where it’s tolerable, natural predators usually catch up by midsummer.

Late-summer webs: fall webworms

The silk tents at branch tips in August and September are webworms eating the leaves inside the web. On a mature tree it’s cosmetic — the season’s photosynthesis is mostly banked. A pole-pruner can pull reachable webs; spraying a whole 80-footer is rarely justified.

The every-other-year crop

Alternate bearing is built into the species: a heavy mast year drains reserves, the next year runs light. It’s biology, not a deficiency — though genuinely poor filling across multiple years can point to zinc deficiency, the classic pecan nutrition gap, which shows as bunched, undersized leaflets (“rosette”) and is fixable.

The conversation that matters: old pecans and storm risk

Here’s the honest part. Pecan wood is brittle, the limbs are enormous, and decades of nut-harvest pruning left many old trees with narrow, bark-included forks. In a July thunderstorm downburst — never mind a named storm — a loaded pecan limb over the roof is one of the higher-consequence failures in a Tallahassee yard. The pattern to respect:

• Co-dominant leaders with included bark — two trunks squeezing a seam of bark in the fork. The seam has no wood connection; it’s a pre-made crack.
• Long horizontal limbs over targets — pecan limbs run heavy and far; end-weight over a roof or driveway is leverage waiting on wind.
• Old topping wounds and cavities — decades-old cuts that never closed become hollow anchor points for exactly the limbs you least want failing.

None of this means every old pecan should come down — most shouldn’t. It means a mature pecan near a house deserves a real risk assessment and, where warranted, end-weight reduction, deadwooding, or cabling and bracing on the big forks — done in the dormant window, before June. That’s the highest-value money a pecan owner spends. See the hurricane tree prep guide for how it fits the pre-season calendar.

What drives the scope of a pecan job

The arborist you’re matched with scopes your specific tree and puts it in a written quote before any work starts. On pecans, these move the number:

When to prune a pecan in Tallahassee

Dormant season — December through February — is the pecan window: structure is visible with the leaves down, cuts seal ahead of the growing season, and the work lands before spring storms. Young pecans repay early structural pruning more than almost any tree; building one dominant leader in the first 15 years prevents the co-dominant fork problem the tree would otherwise carry for the next century. On old trees, dormant-season deadwooding and end-weight reduction — never topping — is the standard. A topped pecan regrows fast, weakly attached, and more dangerous than before; see why topping backfires.

Removal, permits, and what an old pecan is worth keeping for

When a pecan does reach the end — hollow main fork, major limb failures, more deadwood than crown — removal is a heavy-equipment day, and inside the city it generally needs a permit first; pecans aren’t on the protected list, but the ordinance’s size threshold catches essentially every mature one. Start with the Tallahassee tree permit guide, then scope the removal and the stump grinding together — pecan stumps are wide and sucker if left. But get the assessment before the removal quote: plenty of “scary” pecans are structurally sound trees having a normal scab year, and a good arborist will say so.
