Phalaenopsis Bud Blast: Repotting, Light, and Fertilizer Fixes

Why Buds Yellow and Drop

Your white Phalaenopsis loses buds before opening. Likely causes:

1. Root damage from degraded potting mix (stays too wet).
2. Insufficient light—dark green leaves = not enough light for bloom hormones.
3. Wrong fertilizer—high nitrogen (e.g., 30-10-10) promotes leaves over flowers.

Action Plan

• Repot now in coarse fir bark mix if not done in past year. Remove mushy roots.
• Use balanced fertilizer (20-20-20) now; switch to bloom booster in a few months.
• Ensure leaves are yellow-green with slight red pigment for adequate light.
• Don't expect flowers until late winter—new roots need time.
