How to recognise it

Flower buds form apparently normally but then dry up, brown and fall before opening, without any sign of pest damage.

Life cycle and conditions

Usually triggered by a dry spell during the bud-forming period (commonly late summer for plants that flower the following spring), or by a sudden change in light, temperature or humidity, especially for houseplants.

Prevention

Keep watering consistent during a plant's known bud-forming period; avoid moving houseplants suddenly while they're in bud.

How to treat it

🌿 ORGANIC · RECOMMENDED

There's no way to save buds that have already dropped; focus on consistent watering and stable conditions ahead of the next bud-forming period.

🧪 CHEMICAL · IF YOU CHOOSE

Not applicable — no product prevents or reverses environmental bud drop; consistent care is the only lever.
