Japanese Blood Grass in March: monthly care

Japanese blood grass requires minimal pruning, but an annual tidy-up in March keeps it looking sharp and encourages fresh, vibrant growth. By late winter the previous season's foliage will have faded to straw-coloured or brown, and cutting it back makes way for the new red-tipped blades that emerge in spring. Use a pair of sharp garden shears or secateurs to cut the entire clump down to about 5–10 cm above ground level. Work through the clump systematically, gathering handfuls of old stems and slicing through them cleanly. The foliage is fairly soft compared to some ornamental grasses, so the job is straightforward. Rake up and compost the trimmings, or bin them if they show any signs of disease. Timing matters: prune too early in winter and you remove the structure and subtle winter interest the dried foliage provides; leave it too late into April and you risk damaging emerging new shoots. March offers the sweet spot when the worst frosts have passed but new growth is only just beginning. Japanese blood grass doesn't need deadheading because it rarely flowers in our climate—its appeal lies entirely in the foliage. If any flower spikes do appear, you can remove them, though they're uncommon. Throughout the growing season, simply pull away any dead or damaged leaves by hand to keep the clump tidy. This grass doesn't require shaping or thinning; the annual spring cut-back is all the pruning it needs to perform well year after year.
