How to grow Green Manure Spring/Summer Mix

Green manure is a type of cover crop grown specifically to till back into the soil thus adding organic matter and nutrients.  Spring mix green manure is one such blend of different annual plants to sown in spring then turn into the soil in late summer or early fall. The specific blend of plants in a spring mix green manure can vary, but typically includes a combination of legumes (such as clover, peas, and beans) and non-legumes (such as mustards, oats, and rye). Legumes are particularly valuable in green manure blends because they can fix nitrogen from the air and add it to the soil. To use spring mix green manure, you can simply sow the seeds in the spring in an area where you don't plan to grow anything else for the season. Once the plants are established and have grown for several months, you can till them into the soil in the late summer or early fall.  This will add organic matter and nutrients to the soil, improve soil structure, and suppress weeds. It's important to note that you should not till the green manure into the soil when it is in bloom or going to seed, because it will not be as effective in adding organic matter and nutrients to the soil.  Also, it is important to choose the appropriate time to turn in the green manure, depending on the specific crop you will be planting next.   Green manures are a great way to improve soil health, suppress weeds and pests, and add nutrients to the soil. They are a sustainable and environmentally friendly way to fertilise your garden.

When I started this journey in 2009, I found nothing existed commercially, that was reasonably priced and easy to use. There was a homemade system which I also found was not that user-friendly.

Then a friend of mine told me about a homemade method she used. However, when I tried her method, I found this also didn't suit my needs, as it too had flaws that I considered where important. It did not keep vermin out, did not have a lockable lid and (to me) looked unsightly in the garden.
