🌱 How to Care for Hybrid Rhododendron to Prevent Aphids?

💧 How to Water

Water deeply once weekly during dry periods, preferably in the morning. Keep the root ball moist but not saturated - waterlogging is the primary cause of root rot. In hot climates, more frequent watering may be necessary. Reduce watering in winter when growth slows. Morning watering helps prevent fungal issues.

☀️ Lighting

Ideal location is filtered, dappled shade under tall tree canopies with some winter sun exposure for bud development and summer afternoon shade protection. Insufficient light reduces flowering; intense direct sun scorches leaves. North or east-facing positions are excellent choices.

🪴 Ideal Soil

Acidic soil is absolutely essential - pH 4.5-5.5 is ideal. Amend heavily with peat moss, composted pine needles, sphagnum moss, or well-aged compost. Never use lime or soil conditioners that raise pH. Well-draining but moisture-retentive soil prevents waterlogging and root diseases while maintaining consistent moisture.
