Phalaenopsis Flowers Falling at 3 Weeks: Bud Blast Causes

Phalaenopsis Flowers Should Last Months—Not Weeks

A 3-week-old Phalaenopsis in glass vase with rocky media losing flowers on one of three stems.

Normal vs. Abnormal

• Normal: flowers last 2+ months.
• Early drop = stress: ethylene (fruit), temp shock, drafts, fumes.

Watering Error

Watered at 10 days despite wet media. Rule: water when nearly dry, not on a schedule. Rocky media in glass vases drains poorly—high rot risk.

Fix

• Repot after all flowers finish in standard bark mix.
• Drained pot, water when nearly dry.
• Remove fruit, avoid drafts/fumes.

Glass vases with no drainage are display pots, not growing pots. Repot to save the plant.
