Cover crops keep your soil rich in nutrients all year long! Grown as an alternative to bare land when most other crops are not growing, cover crops decrease soil erosion and control weeds and plant diseases in your garden. Organic Hairy Vetch Cover Crop is one of our most popular—it sets more nitrogen than any other variety. For excellent soil conditioning, try our fast-growing Organic Buckwheat Cover Crop. It can grow in adverse soil conditions and attracts honeybees when in bloom.
