Never grown anything that I can recall. But at Let Grow we have a very short explanation about growing “micro-greens” — a clever name for, basically, baby plants that you can harvest before they get bigger. It looks so easy even I — not only not a “green thumb” but basically a thumb-free person — am considering giving it a try. In 2 weeks you’ve got something edible!
Here’s the post with all the instructions. The video (made in conjunction with Birds & Blooms Magazine) is below. If you or your kids DO become micro-gardeners, let me know.
