Hibiscus Yellowing Lower Leaves: Sunlight and Watering Fixes

Large potted hibiscus on east-facing patio (morning sun) drops yellow lower leaves daily despite reduced watering. New growth healthy, many buds. Monthly Miracle-Gro. Last year buds dropped before opening.

Key Factors

Drainage: Pot must have drain hole; empty saucer after watering.
Watering: Water thoroughly, drain excess, allow soil to dry significantly between waterings. Hibiscus prefer drier conditions.
Sunlight: Needs 6+ hours direct sun. Morning-only light likely insufficient—causes both leaf yellowing and bud drop.

Solution

Move to sunnier location (6+ hours). Adjust watering to thorough-but-infrequent. Bud drop should resolve with increased light. Monitor for pests if issues persist.
