Organic soil blend formulated for Equisetum hyemale (miniature bamboo horsetail reed) & similar bog plants. Although Equisetum is a hardy & versatile plant that will grow in a variety of soils, we have found that a blend with organic sphagnum peat moss & perlite produces the fastest & most vigorous growth. This soil blend may be used as a stand-alone potting mix for horsetail reeds & other bog plants, or added to your existing potting mix as a soil amendment.
