Phalaenopsis Bud Blast: Yellow Buds, Then Yellow Leaves in Moss

New Phal in Bud: Buds Yellowing/Dropping, Then Leaves Yellow

Medium light, drying between waterings, in moss. Buds yellow/fall. Then leaves yellow. Moved to another east window away from other plants.

Bud Blast Causes

• Fruit nearby (ethylene).
• Sudden temp changes >10°F.
• Cold window proximity.
• Fresh paint, unvented heaters.

Leaf Yellowing + Moss = Root Rot Likely

• Moss stays wet inside → roots rot.
• Check leaf base for black sooty fungus (from wet leaves overnight).
• Water mornings only.

Action

• If moss: repot in bark mix after bloom (or now if dire).
• Remove dead roots.
• Morning watering, good airflow.
• Fungus on leaves: wipe with alcohol.

Shock from delivery 2 months ago possible, but current care (moss, watering) is sustaining the problem.
