How often does blue oat grass need pruning?

As needed (light tidy annually; hard trim every 3–4 years if clump becomes tatty). Blue Oat Grass is evergreen and does not need an annual hard cut. Remove dead, brown, or tatty leaves by combing through the clump with gloved fingers in early spring. Every few years, a gentle trim to tidy the clump is enough. Over-cutting evergreen grasses can set them back significantly.
