It is time to start preparing for the vegetable growing season in earnest: asparagus, potatoes, onions and leeks can be set out now; in a few weeks, as the soil is workable and warms to about 45 degrees, we'll direct seed radishes, turnips, parsnips, beets, carrots, peas, spinach and other greens and lettuces.
Other cool season crops like broccoli, cauliflower, cabbage and Brussels sprouts do better set out in the garden as seedlings.
