Walk your property and choose a location for planting the rushes. Use horsetails as a natural barrier between a water source and your home. Horsetails prefer growing in sandy soil close to wet areas, but not in them. Select a location that has any level of light, full, partial or shady.
Line a small portion of a koi pond or creek with the horsetails. Plant a barrier plant, like pampas grass, between your lawn and the horsetails to inhibit horsetail growth. Dig a small hole, 2-inches deep for each horsetail rush.
Trim back horsetail to a height of 6-inches, when growth begins to encroach past the landscaping barrier. Do this once in spring and then summer to control growth. Collect all cones from the ground after pruning to avoid growing more horsetails.
