🌱 How to Care for Russian Comfrey to Prevent Aphids?

Water deeply but infrequently, letting the top few centimetres of soil dry out between waterings. Established plants are quite drought tolerant thanks to their deep taproot, though consistent moisture during the growing season encourages lush leaf growth.

Prefers moderately fertile, moist, well-draining soil enriched with organic matter, with a pH between 6.0 and 7.5. Tolerates clay and poor soils once established, though it thrives with compost or well-rotted manure worked in.
