What is the difference between Cool Season Crops and Warm Season Crops?

California cool-season plants prefer a temperature range of 35-75°F. These cool-season plants consist of more leafy plants with large portions of their composition being water. Exposure to temperatures that are too warm can cause premature seed production in these plants, a process known as bolting, bitter flavor, inhibited growth, and sun scold.

Warm-season plants tend to be much larger and enjoy temperatures of 65-90°F. These plants must have six or more hours of sunlight to be healthy. This is why they grow in the long day summer months.

Lucky for Southern California gardeners, many cool-season plants can be planted year-round. We term this group of plants “San Diego Shade Crops”. These include Beets, Carrots, Leafy Greens, Kale, Mustards, and Radish. We call them shade crops since this means that by growing these plants under shade cloth or in a cooler area during the warmer months they can be grown year-round.
