Preventing Fruit on Ornamental Plum: Florel Fruit Eliminator

Effective Product

Florel Fruit Eliminator (Monterey Chemical) — active ingredient ethephon. Breaks down to ethylene, causing bloom drop → no fruit set.

NAA (naphthalene acetic acid) — harder to find, trickier timing.

"Fruitless" plums often revert or are mislabeled. Florel works on any flowering Prunus.
