Cover-All Fall Garden Cover Crop Blend has been mixed specifically for gardens and flower beds. The legumes, brassicas and grains will add nitrogen, keep the soil loose and permeable, promote beneficial microbes and earthworms, fight root nematodes and protect the soil until your next crop of vegetables or flowers is ready to be planted. This 4 lb bag will cover up to 500 square feet. Broadcast and cover seed to just under the soil surface. Before next planting, mow/shred the cover crop and till under. All legumes in this blend are coated and pr-inoculated; no additional inoculation is needed. This seed is non-treated and non-GMO.
