🌱 How to Care for Giant Filbert to Prevent Aphids?

💧 How to Water

Water deeply once a week during the growing season and any dry spells, more often for young or newly planted specimens. Established plants tolerate short dry periods but need consistent moisture while nuts are filling out in summer. Avoid waterlogging, which encourages root and crown rot.

☀️ Lighting

Plant in full sun for the best nut production, though it tolerates partial shade. At least 6 hours of direct sun daily encourages strong catkin and nut development.

🪴 Ideal Soil

Prefers moist, well-drained, organically rich loam with a slightly acidic to neutral pH (5.5-7.0). Tolerates average garden soil but struggles in heavy, waterlogged clay.
