Pruning blue oat grass — FAQ
When should I prune blue oat grass?
Late winter to early spring, before new growth. Rake or pull out dead brown leaves from the clump by hand. Use scissors to cut spent flower stalks to the base. Do not shear the whole plant to ground level as this evergreen needs its foliage year-round.
How often does blue oat grass need pruning?
Annually (tidy); divide every 3–4 years. Blue Oat Grass (Helictotrichon sempervirens) is evergreen and resents hard cutting. In late winter or early spring, comb out dead leaves by hand or with a rake and remove spent flower stalks at the base. Avoid shearing hard to the ground — it can weaken or kill established clumps. Divide every 3–4 years to keep the centre vigorous.
