Spinach! This 70-year-old person who has been gardening all his life has, for the first time raised spinach. This is thanks to the Tower Garden by Juice Plus+. "Your soil is to acid, Melvin. Grow the Swiss chard." "Don't try to grow spinach." Now we're harvesting mild-tasting baby spinach salad greens, fresh from the garden to the salad, no middle man.
