Pruning oriental fountain grass — FAQ
When should I prune oriental fountain grass?
Late winter to early spring (March), once hard frost risk is past. Cut all stems to 3–4 inches above the ground with loppers or shears. In borderline-hardy zones, leave the old stems a little longer for crown insulation and cut back when you see new green shoots emerging at the base.
How often does oriental fountain grass need pruning?
Annually. Oriental fountain grass (Pennisetum orientale) is a graceful, soft-textured deciduous grass that needs an annual hard cut-back in late winter. Without it, dead canes smother new basal shoots and the clump becomes untidy. It is slightly less cold-hardy than P. alopecuroides, so wait until frost risk has eased before cutting to protect the crown.
