hey Ray ko where in central VA are you? i'm in Buckingham
I've got some sort of grass that hitched a ride in with some cow manure, and it grows about 8 ft tall without planting it, wherever i spread the manure i get that mulch crop (whether i want it or not)
But it does a terrific job at keeping out other weeds
Yes, a cover crop is the way to go for winter, or till you have an idea what to plant. i always look for nitrogen fixers, although if you have a specific deficiency you can look for the "weeds" that will mine those minerals and encourage them. comfrey for instance will mine calcium (and other nutrients)
while producing flowers for
bees, forage, chop and drop, and of course highly medicinal--avoid the early growth in spring if you're concerned about the pyrolizidine alkaloids.
We just went around gathering yarrow, chicory, misc things growing wild that we'd like to see more of in the garden.
I like poke- very medicinal-but a specialty plant, so for most folks it's either a spring green, or a succulent mulch plant that is easy to kill by chopping and dropping, or easy to control with judicious pruning, produces fall berries that the birds love, and if you do decide to kill the plant for the sake of others, it leaves a sort spongy hole in the hard clay where its tap
root has softened everything with a deep penetration.
people also talk about using mullein, also a very
medicinal herb, with many uses nice chop and drop, and magical besides, used in many formulas it is the original funeral or graveyard dust,
native americans kept a stalk or two next to the entrance as a protection (also i suspect to restart the fire if it went out).
also plantain, i like the broadleaf, it's so valuable and is growing so well i hate to move or disrupt it, guess finding a market for it would be the best of both worlds, but in the meantime it diversifies and occupies space where other weeds i don't like as much might be
i would also look for lambs quarters which should be producing seed right now, a green that is an easy wild forage replacement for lettuce or kale or spinach (probably has as many nutrients as all three), and comes back on it's own every year
I know this is a bit of a sidetrack , but if your garden looks too neat and under control, it'll give the rest of us a bad name. seriously though, a few easy volunteers Predesigned into the system can help distract insect pests, help diversify everything from soil microbes to available minerals when you start to chop and drop and provide seeds and other forage for wild critters of all kinds.
although my tomatoes hit about 7 ft, the weeds are taller than everything except the loofas which got to climb on a pergola, and i'll probably have to wait for the winter kill to see what is on all the different squashes i planted, cause it's all so overgrown---but i actually kind of like it that way
