It's way too early to plant tomatoes and peppers outside. Those are hot weather vegetables. The cool-season vegetables, however, must be planted soon. It's getting late. They need cool weather to develop properly. Plant seeds or use young plants.

Cool season vegetables that can be planted safely now include onions, leeks, shallots, peas, potatoes, lettuce, spinach, mustard, cilantro, cabbage, cauliflower, radish, carrots, beets, turnips, parsnips, parsley and artichokes.

Most are quite easy to plant and grow. Some need special effort.

Potatoes, for example, should be planted in trenches at least ten inches deep. Cut up the seed potatoes to one "eye" per piece. The eye is the sprout from which a new plant will grow. Cover these pieces two inches deep -- for now. As the plants sprout and grow, continue to fill in the trench. Potatoes will form along the buried stems.
