Apples and Orchids: Ethylene Gas Kills Flowers

Ripening Apples Emit Ethylene—Fatal to Orchid Blooms

True: apples (and other ripening fruit) release ethylene gas, which kills orchid flowers and unopened buds. Plants survive but grow poorly.

Prevention

• Keep fruit ≥10 feet from orchids.
• Don't keep fruit in same closed room.
• Ventilate kitchen if orchids nearby.

Simple habit: fruit bowl far from orchid shelf.
