Should fountain grass or pampus grass be cut down in winter or left to spring?

Answer 1

Fountain grass (Pennisetum) and pampas grass (Cortaderia) can both be left standing in winter to provide winter interest and habitat for wildlife. However, cutting them back in late winter or early spring, before new growth begins, is generally recommended. This timing helps promote healthy growth and prevents the accumulation of dead material. Ultimately, the decision can depend on your garden aesthetic and local climate conditions.
