In these mild winter climates, you can grow artichoke as a perennial vegetable. The ideal growing zones for growing artichoke are zones 7-10. Sow 1-3 artichoke seeds 0.5 inches deep down the potting or garden soil.

Artichoke can be grown vegetatively and by means of seeds. You can grow from seeds, suckers, and root crowns. For the sale of this article, I’m going to only discuss how to grow artichoke from seeds and crowns.

Let us get started.

How to grow artichoke

The best way to grow artichoke successfully is from root crowns. This is because root crowns are already established and they grow fast. Unlike, seeds, which they need to pass all the four major Plant growth stages. Sometimes, artichokes that are grown from seeds do not grow true to their parents. They may be less adaptable to pests and diseases. Some may produce lower yields with less flavor.

How to grow artichoke from seeds

Here is a step by step guide:

1. Choose the best artichoke variety: the first is to find and buy good quality artichoke seeds. Buy artichoke seeds that are open-pollinated, heirloom, organic. These are pure original. They produce artichoke plants, which are true to their parents.

Artichoke varieties come in different shapes, colors, flavors, and sizes. The common two varieties that are widely cultivated are the globe and elongated artichokes. Green globe artichoke is a good variety that is widely cultivated by most artichoke growers.

Green globe artichokes are heavy producers which produce about 4-5 inches of artichokes. The artichokes have tender, creamy, and delicious flower buds. Green globe artichokes are open-pollinated and usually take 90-100 days from planting to harvest.

2. Choose a quality pot: if you are growing your artichokes in the garden ground, skip this step. Artichoke likes a well-drained and fertile environment. So, find and buy good pots. Use good ceramic pots such as terracotta pots. You can find these pots on Amazon.

Do not use black plastic containers. These types of containers absorb more heat and heat up the interior, and this may hinder your artichoke’s healthy growth.

If you find the right containers, fill them with a good potting mix. Find and buy a good potting mix from gardening stores or your local gardeners. Do not use garden soil because garden soil can contain weed seeds and pathogens. Both weed seeds and pathogens can affect the healthy growth of your artichokes.

However, you can also use garden soil, but you need to sterilize the garden soil in the oven. Then, you need to mix in compost, cocopeat, sand soil, dried leaves, and rabbit manure. Then, fill the pots with the prepared soil.

3. Choose a good garden spot: if you are planting the artichoke seeds in the ground, you need to locate a spot that receives partial sunlight. Artichoke plants love well-drained and fertile soil with a pH that is near neutral (6.5-7.0). The location should also be well-ventilated and free from rodents, snails, and slugs.

4. Prepare the garden spot: the next step after locating the good garden spot is to prepare and make the spot ready for planting artichokes. Use your garden rake and fork to loosen the top 10 inches of the soil. Remove large rocks, stones, roots, and other plants from the soil.

Prepare rows that are 8 inches deep. Leave at least 48-72 inches in between if you are planning to grow the artichokes as perennial plants. However, I do not recommend this space if you are just growing them as annual.

After you have finished making the rows, I recommend that you need about 4-5 inches of well-aged compost. Mix in the compost before planting and then spray gently the garden with water.

5. Plant the artichoke seeds: sow 2-3 artichoke seeds about 0.5 inches deep. Space them at least 8-10 apart if you are growing artichokes as annual. However, if you are growing as perennial plants, space plants about 24-35 inches apart. Thin out the less vigorous seedlings after germination and leave only one healthy seedling. The right time for planting in March or April.

And if you started the artichoke seeds indoors, you can transplant the seedlings to their permanent pots or garden spot when they grow at least the first five true leaves. Space the seedlings about 24-35 inches apart.

6. Keep the soil and seeds moist: immediately after you finish with the planting, water gently to keep the pot or ground and the seeds moist.

7. Take care of your garden: after planting, do not add fertilizer. This is if the soil is well fertile. However, if it is not, you can apply a slow-release liquid fertilizer. Water regularly to keep the soil moist so that germination can take place quickly. Then, after germination, water 1-3 times a week. You also need to apply nitrogen riched fertilizer every two weeks.

Weed the garden when needed. You need to cover your artichokes with mulch in late autumn if you are living in colder regions. And if you are living in warm climates, mulch the garden in spring. When the surface of your artichokes garden becomes warm and moist, apply high potassium general fertilizer.

How to grow artichokes from root crowns

Here is the step by step instructions:

1. Find artichoke root crowns: you can find these root crowns if you already have an artichoke plant. However, if you do not have them, they are also available at many garden stores and nurseries.

2. Prepare the garden spot: to prepare the garden spot, follow the procedure I mentioned above. But, in this case, you need to add potassium-rich fertilizer before planting the root crowns. Water the soil to wet the surface.

3. Plant the artichoke root crowns: dig about 6-8 inches of holes. Add in root booster that contains enough mycorrhiza and vitamins. This root booster helps quicken the growth of your root crowns. When you added the root booster, place the root crowns in the holes one per hole. Cover the root crowns with 6-8 inches of soil.

4. Water the surface of the soil after planting: water the surface of the garden. This watering can help dissolve nutrients and make the nutrients available to the root quickly.

5. Mulch the bed: you need to also mulch the surface of the soil where you planted your root crowns. This mulching helps prevent weeds’ growth, which in turn helps prevent competition.
