Dwarf Horsetail Care

In terms of moisture level in the soil, horsetail prefers a soil that is at least moderately wet. It can even grow in standing water up to a depth of about 4 inches. It's well-suited for rain gardens and other areas that may periodically flood.

Prune the horsetail if the stalks become damaged by cutting them off at ground level. If you cut mid-branch or higher the plant has a tendency to branch into multiple stems, making it top-heavy.

Regular fertilization of your Dwarf Horsetail Rush will keep it growing well all season long. CrystalClear Thrive Fertilizer Tablets can be pushed into the soil at planting time and from April through August, see label for fertilizer application rates.

Full Sun to Partial Shade.

The young plants are eaten cooked or raw, but considerable care must be taken. If eaten over a long enough period of time, some species of horsetail can be poisonous to grazing animals, including horses. The toxicity appears to be due to thiaminase, which can cause thiamin (vitamin B1) deficiency.
