Plant lettuce, peas, cabbage (transplants), cauliflower (transplants), carrots, radishes and spinach. These vegetables can germinate and handle lower soil temperatures in the warmer parts of the garden (45F soil temperatures for germination). Prepare the soil by loosening it and applying a starter fertilizer high in phosphorus. Cover the seeds with a dark topdressing to help warm the soil. Activated carbon works great for transferring heat to the soil.
