There are many things to consider when it comes to growing artichokes, such as time, place, sowing, and maintenance. So, how to grow artichokes correctly?
The first step of growing artichokes is sowing. The best place to start seeding is indoors or in a greenhouse with controlled environment. You can seed the plants at least 8 weeks before the last frost date. When the seedlings are strong enough, harden them before transferring to soil. They need to experience chilly climate so you can put the plants outside in mid-spring for a week.
Gardener in cooler regions should plant in the early spring. After the last frost, you can transfer the seedlings in soil or in containers and overwinter the plants. They will produce buds in spring so it won’t be disturbed by chilly winter.
Before transferring the seedlings, choose fertile and well-drained soil. Artichokes can grow quickly so it needs a lot of water and nutrients. To plant the seedlings, prepare the soil with 2-inch compost and make holes 2 to 3 feet apart.
Once your artichokes are transferred, you should keep them from wet soil but giving sufficient water is also necessary to produce large buds. Too dry soil will result in fewer and smaller buds. Be sure the soil has well drainage as poor drainage can cause rotten roots.
How to grow artichokes is actually easy. The plants don’t need intense treatment as they don’t have many pests. You may only need to weed the area and put mulch to keep the soil moist. Fertilize the plants with organic fertilizer that contains high nitrogen for excellent harvests.

In warmer climate such as California or Mediterranean, the plants produce buds throughout the year but mostly they begin in summer. The buds can be harvested when it reaches 3 inches. Make sure to harvest the buds before blooming. To harvest the buds, cut them along with the stem.
After the buds are cut, the plants begin producing smaller buds. You can wait for the next harvest. Some gardeners cut the stalk an inch below the ground. This treatment helps encourage the development of new shoots for the next harvest.
A well-maintained artichoke plant can produce up to 15 years. But the gardeners need to remove the side shoots in order to prevent overcrowding that diminishes productivity. However, most gardeners replant the artichokes every 5 to 10 years for excellent harvests rather than pruning the stalks.
