Gardenia Bud Drop and Leaf Damage: Temperature, Light, and Pest Management

Bud Drop Causes

Sue's month-old gardenia houseplant losing buds with brown bases. Primary triggers:

• High night temperatures
• Low light intensity
• Natural thinning: Some drop is normal

Water Management

• Keep soil uniformly moist, not wet during flowering
• Avoid fluctuations between bone-dry and saturated

Leaf Damage: Insect Feeding

Holes and ragged edges indicate chewing insects.

Treatment Sequence

1. First: Wash leaves with soapy dish water
2. If persists: Neem Oil Spray (Dyna-Gro) — organic, non-washing, indoor/outdoor safe

Environmental Optimization

• Bright light all day (good)
• Monitor night temperatures
• Consistent moisture
• Neem oil provides ongoing protection

Gardenias are sensitive; stable conditions and gentle pest management yield best results.
