We moved to Madras, Oregon in May 2012. Our backyard has about 1 inch of top soil & under it is the builders trash, cement & rocks. There is not an inch where I can put a fork into the ground. My husband built a raised bed and tis summer we had lots of different kinds of lettuce, bok choy and got 1 small butternut squash and several zuccini. I would like to garden all year long if possible. I started seeds, in september, of Swiss chard, broccoli, kale, spinach and cauliflower but they are not doing very well, they took a long time to germinate and now seem to be stunted. Help!
