Planting Artichoke Seeds Or Transplants

Artichokes, scientifically known as Cynara scolymus, are perennial plants that belong to the thistle family. Native to the Mediterranean region, they have been cultivated for centuries for their tender and delicious flower buds. Artichoke plants require a long growing season, rich soil, and moderate temperatures. While they can be challenging to grow in regions with harsh winters, they thrive in areas with mild to warm climates.

When it comes to planting artichokes, you have two options: starting from seeds or using transplants. Starting from seeds allows you to have a wider selection of artichoke varieties, while transplants provide a head start and ensure a more consistent outcome. Let’s explore both methods in detail.

Starting From Seeds

If you choose to grow artichokes from seeds, it’s important to start the process indoors about eight weeks before the last expected frost date in your area. Here’s a step-by-step guide to help you get started:

Fill seed trays or small pots with a high-quality potting mix. Make sure the containers have drainage holes to avoid waterlogging.
Moisten the potting mix with water until it is evenly moist but not soaking wet.
Sow the artichoke seeds about ¼ inch deep into the potting mix. Space them at least 2 inches apart.
Cover the seeds with a thin layer of potting mix and gently press it down.
Mist the surface lightly with water to ensure good moisture contact.
Place the trays or pots in a warm and well-lit area, ideally near a south-facing window or under grow lights.
Maintain a temperature of around 70°F (21°C) for optimal germination.
Keep the potting mix consistently moist, but avoid overwatering, as it can lead to damping off or fungal diseases.
In about two weeks, you should start to see the seedlings emerge. Once they have developed their first true leaves, you can transplant them into larger containers or separate them into individual pots.
Continue to provide ample light and maintain a temperature of around 60°F to 70°F (15°C to 21°C) until it is time to transplant the seedlings outdoors.

Using Transplants

If you prefer a more straightforward and reliable method, using transplants is an excellent option. Transplants can be purchased from nurseries or garden centers, or you can grow your own from seeds and then transplant them. Here’s how to properly plant artichoke transplants:

Choose a planting location that receives at least 6 hours of direct sunlight per day. Artichokes thrive in well-drained soil with a pH between 6.0 and 7.5.
Prepare the planting area by removing any weeds or grass and loosening the soil to a depth of 12 to 15 inches. Incorporate organic matter such as compost or well-rotted manure to improve the soil’s fertility and drainage.
Dig a hole that is wide and deep enough to accommodate the artichoke transplant’s root ball. Space the holes about 3 feet apart to allow room for the plant to spread.
Gently remove the artichoke transplant from its container, being careful not to disturb the roots too much.
Place the transplant into the hole, ensuring that the top of the root ball is level with the surrounding soil.
Backfill the hole with soil, firming it gently around the base of the transplant to remove any air pockets.
Water the newly planted transplant thoroughly, making sure the soil is evenly moist.
Apply a layer of organic mulch, such as straw or wood chips, around the base of the plant, leaving a small space around the stem to prevent rotting.
