Most gardeners in USDA Zone 7 or higher could easily have a set up like this.
For our Winter garden this year I went with all container plantings. It was a good thing too–when the bomb cyclone hit in December, and our temps went down to 8.9 degrees F, I just wheeled three cart loads of plants into our 60 degree basement, left them there for a couple of days, and then brought them back out. We will now have fresh greens until spring planting, which actually begins this week.
Pictured is a mixed planting of lettuces, spinach, boy choy, radishes, onions, chard, collards, kale, and one container with a mesclun mix that includes arugula. The potting soil is 95% composted chicken manure, a by product of our egg layers, that produce a more than steady supply of it. The spinach quiche we made was the perfect combination of their products.
Grand total of the expenses for this garden was $20 for seeds. I’m going to splurge and spend $40 on the summer version, which will easily be double this size. You won’t hear any complaints about the price of lettuce from me.
