How to Grow Japanese Blood Grass
The Japanese blood grass plant is low maintenance and has few pests or problems. The biggest issue is when the plant is not sited correctly. It prefers cool, moist locations and tends to revert in full shade, which makes it a potential hazard to native plants. Gardeners that are growing Japanese blood grass in southern states may find it weedy.
When the plant is too wet, however, the roots can get a variety of rots. Amend your garden soil with some gritty material and compost and check the drainage before you install this grass.
It is tolerant of urban pollution and drought-resistant once established. For color and persistence, the Japanese blood grass plant is an ideal candidate for most cultivated gardens.
Care of Japanese Blood Grass
The better the sun exposure, the truer and deeper the red color becomes in this spectacular ornamental grass. Established plants can withstand low moisture situations, but for the best appearance, water once weekly. Water plants in containers at least once per week in summer but reduce watering in winter as the plant goes dormant.

As long as the Japanese blood grass plant is installed in well-draining soil, few problems exist. However, those in clay soils tend to have wet roots, which promote root rots and fungus. The blades of the grass may get eaten by snails and slugs and can also get rust disease, which disfigures the leaves. Avoid overhead watering and use an organic slug bait to keep the brilliantly colored foliage free of holes and damage.
