Growing

Galeopsis pubescens thrives in well-drained sandy, loamy, or light clay soils with a pH between 6.0 and 7.5. It prefers open sunny locations and tolerates poor fertility better than rich soils. Direct sowing is recommended as it does not transplant well. Avoid deep cultivation in autumn to preserve seeds. No pruning is required; deadhead spent flowers to limit self-seeding.
