10 Tree Care Myths That Could Kill Your Athens Trees

Bad tree advice spreads fast. Here are 10 common myths we hear from Athens homeowners — and the real science behind tree care.

Myth 1: Topping trees makes them safer

Truth: Topping makes trees MORE dangerous. The weak regrowth that follows is poorly attached, fast-growing, and prone to failure within a few years. Properly thinned crowns are safer.

Myth 2: Pruning wounds should be sealed with paint

Truth: Wound paint actually traps moisture and promotes decay in most cases. Trees seal their own wounds through natural compartmentalization. ONE exception: oak wounds during oak wilt season should be sealed.

Myth 3: 'Mulch volcanoes' help trees

Truth: Mulch piled against the trunk holds moisture against the bark, invites disease, and encourages girdling roots. Keep mulch a few inches away from the trunk, spread in a ring.

Myth 4: Trees need fertilizer like lawns do

Truth: Established trees in Athens almost never need fertilizer. Lawn fertilizer can actually harm trees by causing rapid weak growth. Soil testing first is essential before any fertilization.

Myth 5: All ivy will kill trees

Truth: English ivy can be problematic if it gets into the canopy, but ivy on the trunk alone doesn't directly harm the tree. The bigger issue is that it hides decay and pests from view.

Myth 6: Big trees should be staked permanently

Truth: Stakes should come off within 1–2 years of planting. Permanent staking weakens trunk development.

Myth 7: A leaning tree will fall soon

Truth: Many trees lean their whole lives without falling. A NEW lean is concerning; an old lean usually isn't.

Myth 8: Removing one side of a tree balances it

Truth: Asymmetric pruning destabilizes trees. Pruning should always maintain balanced structure.

Myth 9: Climbing spurs are fine for pruning

Truth: Spurs leave permanent wounds that invite decay. Spurs are appropriate ONLY for removals, never for pruning.

Myth 10: Tree roots are as deep as the tree is tall

Truth: Most tree roots are in the top 18 inches of soil and extend 2–3 times the canopy width. This matters a lot when planning construction near trees.
