The Q&A Archives: Winter Gardening

Question: I'm planning on trying a winter garden this year. I'm building a 6'x 3" insulated sun box which will be placed on a south-facing slope, sheltered from the north. I'm trying to figure out what plants can be grown in it. I heard there are some lettuces, spinaches, root crops, radishes, kales, and some oriental veggies that can be grown in a sunbox in my zone. I'm having trouble pinpointing exact varieties though. Do you have any suggestions?


Answer: The crops you mention are all good candidates for cool-season gardening. My favorites include the salad green Arugula (35 days), 'Chicago Red' beets (49 days), 'Simpson Elite', 'Mighty Red Oak' and 'Gourmet Blend' leaf lettuces (45-50 days), 'Baby Leaf Hybrid' spinach (42 days), 'Bright Lights' swiss chard (60 days) and 'Burpee White' radishes (25 days). You can order seeds online at or phone (800) 888-1447 to place your order.

Hope you have a terrific harvest!
