Hi, I'm preparing my lightly slashed, un-tilled (for the season) cover crops. I plan to sow them early in the year and try to win the war against agressive pioneers and/or get more useful organic material to live and die on my plot. My soil is heavy clay and I have no irrigation, hence all the roots. I'm doing several hugelculture patches (4-ish, 1 is done) and the total area is about 100-150 meters square (0.3 acre or less). I have free invasive black locust, but the people who own the place want them slashed, Oh, and I'll be doing much more with Sunchokes next year with this year's seeds.
Here's my current strategy. Any observations or suggestions are very welcome.
OT, but I'm pretty sure sunchokeseed's sterile, but you may mean the tubers. They are very much not sterile! I'd be wary of planting lemon balm (or any mint) actually in your beds as it's really rampant. I always suggest favas in the 'nitrogen fixing' camp. They also provide huge amounts of organic matter and bonus carbon if slashed when mature. And they're edible
Ah, permanent-ish stuff. NZ white/Dutch clover's great for a low-gowing thing. Sometimes walking on, rather than wading through makes a nice change Comfrey. Plantain (the forb, not the banana) if the soil's not really alkaline. My parsnips self-seeded and popped up everywhere. They can go down deep and the insects go nuts for the flowers. Achillea (yarrow) is really drought-resistant, a great compost activator, medicinal plant and insect food. Good thing it's amazing, since you couldn't get rid of it if you tried!
