New Phalaenopsis Loses All Flowers in Two Weeks: Ethylene Gas Suspect

Your white moth orchid (4 blooms, 3–4 buds) lost all flowers and buds in days. Stem is green. It's by a shaded window, 60s°F, in moss (still damp). You ask what happened.

Prime Suspect: Ripening Fruit Nearby

Ethylene gas from ripening fruit kills orchid flowers and buds. Move fruit or orchid immediately.

Stem Still Green? Wait and Watch

If tip doesn't brown, it may rebranch. Cut only when tip browns: go down to lowest flower node, down further to a bump (node), up 1 inch, cut. Secondary spike may appear in 3–6 weeks, bloom in 2–3 months.

Moss Is a Risk

Moss holds water too long, rots roots. Replace every 6–12 months. Repot in bark mix after bloom.

Follow-Up: Clivia Neighbor Unlikely Cause

Unless Clivia flowers are fragrant (ethylene source), it probably didn't cause blast. Good move separating them anyway.
