The coastal region of southern California has a climate found in only four other areas of the globe. Because the southern California region is virtually free of frost damage, crops can be harvested up to five times a year. In addition, the soil of the region has a high mineral content which makes it ideal for growing crops. Home gardeners will delight in the choices available for planting and harvesting their own fresh vegetables.
Artichoke should be planted in southern California from May through July on the coast and in July in the interior region of southern California. Varieties of artichokes which do well are Emerald, Green Glove and Imperil Star. Artichoke growers should take precautions against gophers eating these vegetables. They do well when they do not receive any water for two to three weeks during the summer.
