Rhododendron Watering Issues Near Daily-Watered Annuals

Balancing Moisture for Rhodies and Begonias

Daily watering for begonias likely oversaturates rhododendrons in northern Illinois. Check soil—if muddy and poorly draining, reduce frequency. Rhododendrons need deep weekly soakings, not daily light watering.

Correct Approach

• Water deeply once weekly without rain
• Ensure excellent drainage for rhododendrons
• Begonias also prefer moderate, not daily, moisture
• Mulch both to retain consistent moisture

Overwatering causes root rot and leaf browning in rhododendrons.
