Long regarded as a tasteless vegetable, modern chefs have raised the humble Brussels sprouts to almost cult status. Prices in the stores for organic sprouts will deter many people from even trying them, so consider growing your own. Honestly, you'll realize why these little cabbages are so expensive once you start tending to your own plants. These are not the fastest vegetable to harvest and you'll need to do battle with hungry bugs (row covers help immensely), but the effort will be well worth it.
Plant as soon as the soil is workable and consider using row covers for the entire growing season. These plants grow mostly up, so space transplants about 18" apart. The little heads will mature from the bottom up. Harvest each head by snapping off the leaf below the bud then use a sharp knife to remove the head. Yes, much more labor intensive than grabbing the already cut heads from the grocery store, but the taste will delight you.
