Cabbage...beets...turnips...Spinach...arugula...Mustard greens.
Thanks for those suggestions. I think I might even have some seeds from prior years for the beets, turnips, spinach and mustard greens.
I just got a 4 unit 2" soil block maker, so I think I'll try to start those older seeds in some soil blocks and transplant them if they germinate. With all the heat and little to no rain this year, lots of my direct in soil seed planting just did not take this year. I'm thinking that if I start the seeds in some soil blocks, I might be able to keep the blocks moist long enough for the seeds to germinate properly and then transplant the best plants.
