I am in Southern Wisconsin, zone 5a. We have legendary soil here, "Black Earth," and relatively few pests, from what I understand. Lots of beetles but they're fairly easily trapped (I've not had to; they've left my yard alone), but plenty of
deer and
rabbits. A simple scarecrow of sweaty clothes can help keep them at bay (just hang the garments up around the garden) OR little mesh/thin cloth baggies of human hair from the hairbrush! Put them on stakes, cages, on the
fence if you have one, or wherever they can be hung up off the ground. One baggie of hair
should cover at least 3m radius of garden. The scent of hooman is what you're after to spook critters away. Cats & dogs are good at spookin', too.
Here are the easiest, most prolific plants I've had:
1. Kohlrabi, Brassica olearcea. It's radish-like, biggish, with edible leaves. Tasty both raw and cooked!
2. Black Mustard, Brassica nigra. (only variety with which I have
experience) I am so in love with this plant. Planted a Mesclun mix seed packet one year, and almost all the plants continued to self-seed, but the mustard was most robust! It will take the f*** over!! Leave them close together for leggy plants (bolted) with lots of seeds for your dhal, curry, prepared mustard, or
medicinal salve, poultice, or hot compress (can help fight winter illness), or give each plant a good meter radius of space for some serious leaves!! I s**t you not, each plant can grow to a meter wide at the base, and like 2m tall. The old leaves at the bottom get super large and the plant tapers up like a cone, with the mild young leaves near the top. Then the cute yellow flowers shoot up and it's rather majestic, if you ask me. The leaves are piquant, especially as they get mature and large. Beloved by
bees!
3. Beets, Beta vulgaris. (I just learned these are in the amaranth family! Redness!) Surprised no one has mentioned these beauties because they are a
staple in Wisconsin veggie gardens. Maybe other soils cannot support them? I love them raw, roasted (with a little oil or ghee and wrapped in its own leaf 😉), and pickled, and the greens are my favorite of them all, and they are huuuuge! I've never done so, but I'm sure a dye could be prepared from these, and also sugar!
Bonus herb (not a vegetable): Garden sage, Salvia officinalis. It is a hardy evergreen subshrub that actually survives Wisconsin's harsh winters! You can pluck aromatic leaves all year round!! It is such an impressive plant to me; I love the woody trunk and its gnarly forms. Also beloved by
bees!
