Bougainvillea Watering Secrets: Why Flowers Drop and How to Prevent It

Understanding Bougainvillea Bloom Cycles

In warm climates, bougainvillea sets flower buds every 4–6 weeks, especially after pruning. Overwatering suppresses flowering and causes root rot.

Proper Watering Technique: Deep and Infrequent

Let the soil dry out until the plant nearly wilts, then water thoroughly. Water again after a short interval to ensure the entire root ball is saturated. Repeat only when the soil is truly dry.

Sunlight Requirements for Maximum Blooms

Full sun from 11 AM onward is ideal. Afternoon-only sun (2 PM to sunset) may be insufficient for heavy flowering.

Fertilizing Without Burning Roots

Always water well before applying fertilizer. Use a balanced formula after pruning to encourage new growth and buds.
