Grow green manure seeds to quickly improve soil health, suppress weeds and boost fertility between crops. FAQ What are green manure seeds? Green manure seeds are cover crops sown to build soil organic matter, fix nitrogen, suppress weeds and protect soil between cash crops. When should I sow green manure? Sow late summer to early autumn for winter cover; sow spring or early summer for quick summer green manures like buckwheat or phacelia. How long before I dig in green manure? Incorporate most green manures before flowering to maximise nutrient return and avoid seeding; legumes are usually dug in when in full leaf but before heavy pod set. Can I sow green manure in containers? Yes. Use larger containers, allow room for root growth and cut or compost the crop before it sets seed. Will green manure become a weed problem? Only if allowed to set seed. Prevent this by cutting or digging in before flowering; choose species suited to your rotation and climate. Which green manure fixes nitrogen? Legumes such as crimson clover, red clover, field beans and forage pea fix nitrogen when incorporated while green. How do I sow on heavy or wet soil? Avoid sowing into waterlogged ground. Improve drainage first or choose a later sowing window when soil is drier; consider surface sowing and light rolling for small seeds. What are typical sowing rates? Sowing rates vary by species and bed size. Follow pack guidance; if unsure, we can provide pack-size to bed-area recommendations. Can I buy a ready mixed green manure seed blend? Yes.
