Sweetgum Ball Control: Limited Options for Large Trees

25-30 yr old sweetgum produces thousands of spiky balls. Owner asks about topping, heavy pruning, or spraying to stop seeding.

Pruning Backfires

Flowers form on new growth; pruning stimulates more growth and more flowers.

Florel (ethephon): Hormone spray at full bloom, precise temp/dosage. Risk of damage. Full canopy coverage hard on large tree.
Snipper: Micro-injection at bud stage. Professional only.

No practical complete prevention for large trees. Cost of treatment may exceed cleanup annoyance. Consult certified arborist for estimates.
