Worst Weeds in Landscape Plantings
Field Horsetail - Equisetum arvensis
Unlike the other weeds featured here, field horsetail,
at right, doesn’t have true leaves. Rather, it produces clusters of short,
needle-like branchlets at joints along the main stems. In areas heavily infested by horsetail it often appears as though
the ground is covered by evergreen seedlings, below left.
Like other weeds featured here, horsetail is invasive and persistent because of vigorous, wide-spreading rhizomes. When disturbed, pieces of rhizomes no more than one half-inch in length can send up new shoots from a foot or more beneath the soil surface!
