How to Grow Purple Italian Globe Artichoke Seeds
When to Plant Artichokes
Artichokes are grown successfully in warmer climates, so January-March is prime planting time! Colder zones will need to start indoors under fluorescent lighting 2 months before the last frost.
Where to Plant Artichokes
Pick a spot that has loose and well-draining soil and is well fertilized. Artichokes thrive in partial to full sun.
How to Grow Artichokes
Carefully decide where you would like to plant your artichokes, as this will be considered your “perennial garden” that you will not be tilling up each year like you do for your annuals. Artichokes grow best where there are mild winters and long, frost-free, moist summers. They will need at least 100 frost-free growing days. Amend your soil with organic compost and keep it evenly moist, allowing soil to dry between watering. Sow seeds ½” deep and thin to 6’ apart. Where winters are cold, cut plants back to 10” and cover with a box or basket, mulching with straw or leaves to help maintain an even soil temperature. Artichokes bear best the 2nd year and should be started from new plants every 3-4 years.
How to Harvest Artichokes
The artichoke is an edible thistle flower bud which is eaten before it opens. If we wait until full maturity, it blooms a beautiful purple thistle. Harvest artichokes during the 2nd year, cut buds about the size of an apple before they open. Cut stems about 1 ½” below the bud.
**Artichokes are tender perennials that grow from 3-4 feet tall and 6 feet across. A nice companion plant to put with your artichokes is asparagus, as these are perennials as well and will come back for you year after year.
