Raddish, Mustard, Lupines, Phacelia and a super high diversity insect friendly flower and grass mix.
The concept is to use these plants to enhance soil content and structure. Esp the raddish, daikon winter seed, promises to increase soil organic matter and deepen the aerobic layer.
This is a fascinating project Frank, both for horticulture and photography.
Have you ever tried Fenugreek (or as the Indians would say, Methi)? I used to sow this as a green manure, along with Mustard.
Was going to just dig them each in until I noticed the aroma - both are delicious, plus a free source of nutritious greens, ideal for a stir fry or when young maybe even straight into salads.
It might be just a little late for Fenugreek to produce much now, subject to when cold sets in. But tried in April, you'll get something delicious in a few weeks and actual pungent Fenugreek seeds if you leave them long enough
