Datura Bud Drop: Identifying and Treating Spider Mite Damage

Datura Bud Drop: Spider Mites Are the Likely Culprit

When datura (angel's trumpet) buds swell but fall off before opening, the cause is often spider mites feeding on the developing ovaries. These tiny arachnids are relatives of spiders and thrive in hot, dry conditions.

Diagnosis

• Check the undersides of leaves for fine webbing.
• Tap a bud or leaf over white paper; moving specks indicate mites.
• Buds may turn brown or black before dropping.

Treatment

Apply a miticide or horticultural soap (such as neem oil or insecticidal soap) thoroughly, covering leaf undersides. Repeat every 7–10 days for at least three applications to break the life cycle. Increase humidity around the plant by misting or using a pebble tray, as mites hate moisture.

With prompt treatment, new buds should develop normally.
