Hmm.. it's been almost 3 weeks (21 days) since seeding and some of the radishes must be almost ready to harvest?
There are some spinach (not just the transplanted ones) that look like they can be picked in the next couple of days!
Have seeded more spinach and radishes in empty beds as well as radished between some tomato beds - companion plants, eh?
Read an article that said the Iroquois planted corn, then beans and squash all together which worked very well. Unfortunately, the present corn bed is too narrow - next year maybe?
