New varieties. Where winters dish up only a few frosty nights, plants will sometimes overwinter when pruned and mulched (zones 8 and 9). Some of the most popular types of artichoke include: While overwhelmingly hardy plants, gardeners should be on the alert for a few of the following common pests and diseases for artichokes. Artichoke has few problems. Mulch with an organic material, such as dry grass clippings, straw, aged manure, or a mixture of these. In spring, after the ground is no longer frozen and before growth begins, remove the winter covering and add a 1-inch layer of compost or well-rotted manure around the plant. Artichokes can also grow well in large containers. (Some gardeners have reported success at overwintering plants as far north as zone 5 using the techniques described for zones 6 and 7.). Artichokes grow pretty tall, so place them accordingly. Remove the outer 2 layers of leaves from around the stem. Identify your growing zone. Add a layer of mulch (straw is great at this point) over and around the bushel basket. Also be sure to keep soil moist throughout the growing season. Artichokes require just a bit of work after harvest to become edible. In such growing conditions, they are perennials, yielding harvests for up to 5 years. Transplants from indoor starts or dividing ensures you grow exactly what you want. If artichokes are perennial to your region, think long term about where to plant them because they’ll grow in that spot for up to 5 years. So much to grow, so little time. With their large, silvery-green leaves and thick stems topped with pinecone-like flower buds, artichoke plants add a strong architectural element to vegetable garden plantings. Harvest continues into mid-June. Plant artichokes 4 feet apart in an area with full sun to partial shade and nutrient-rich, loamy soil. When inspiration grows all around you, you can’t help but create masterpieces. The artichoke is a member of the thistle family and grows large stalks with edible buds that are widely used in culinary dishes around the world. When you see a Bonnie Harvest Select plant, you should know that it has success grown right into it-helping you get a head-turning harvest and mouth-dazzling taste. Otherwise, simply peel it with a paring knife. You’ll need at least 4 feet of spacing around each plant. As buds begin to form, remove mulch, and apply a 4-inch-thick layer of compost around each plant, extending from the base of the plant outward 12 inches. Water right after planting and provide consistent soil moisture throughout the growing season by watering when the top inch of soil is dry. Because harvest increases with plant age, it’s best to try to “overwinter” artichoke plants using one of the techniques below. If only a few leaves are infected by botrytris blight, remove and destroy them. Block weeds and retain soil moisture by adding a 4-inch layer of mulch made from organic material (such as straw, dry grass clippings, or aged manure) to prevent weeds. From the moment you pick it up, you’ll notice these nozzles are different. Most artichoke plants reach harvest in 85 to 100 days. The Moors were eating artichokes around 800 AD when they brought them to Spain and the Spanish were still eating them when they brought them to California in the 1600s. Two reasons artichoke plants fail are summer drought and winter soil that’s waterlogged. Artichoke seeds are usually only 80% true to their parent plant. Many people think of thistles as prickly weeds, and no gardener wants a weed in their vegetable garden.
