The Growing Seasons

Vegetables are divided into two categories: warm-season and cool-season crops. Gardeners in cooler climates with short summers may find better luck growing warm-season vegetables (such as tomatoes, peppers and squash) in a greenhouse to extend the growing season. While nearly all vegetables prefer full sun (6 or more hours daily), some cool-season crops, such as lettuce and radishes, can get by with 4 to 5.
