Why Topping Liquidambar (Sweetgum) Trees Is a Mistake

Don't Top Your 45-Foot Liquidambar – Here's Why

Topping – cutting the main leader or upper crown – is never recommended for liquidambar (sweetgum) or any shade tree.

The Science Against Topping

• Crown = food factory: The canopy produces carbohydrates stored in roots for next spring's growth. Removing it starves the tree.
• Meristem removal: The apical meristem (top growth point) regulates form and vigor. Its loss triggers weak, poorly attached water sprouts.
• Decay entry: Large stub cuts don't compartmentalize well, inviting fungi.
• Permanent disfigurement: The tree never regains its natural form.

Proportions Matter

A healthy tree's crown is 1/3 to 1/2 of its total height. Arbitrary height reduction destroys this balance.

Alternatives for Size Management

1. Crown reduction by a certified arborist: Selective cuts back to lateral branches ≥1/3 the diameter of the removed limb.
2. Crown thinning: Removes crossing/rubbing branches to reduce wind sail and weight.
3. Plant the right tree: If space is limited, replace with a smaller species.

Topping creates a hazardous, high-maintenance tree. Invest in proper pruning or replacement instead.
