You can definitely grow cardoon from seed! It’s a great way to start your cardoon plants and have a bountiful harvest of young leaf stalks. Here are some tips for successfully growing cardoon from seed:
1. Start indoors: Cardoon seeds should be started indoors about 6 weeks before the last frost date in your area. Fill seed trays or pots with a good quality seed starting mix, and sow the seeds about 1/4 inch deep.
2. Provide warmth and light: Cardoon seeds germinate best in warm temperatures, ideally around 70 to 75 degrees Fahrenheit. Place the seed trays in a warm and well-lit area, such as near a south-facing window or under grow lights.
3. Water regularly: Keep the seed starting mix moist but not waterlogged. Use a spray bottle or a gentle watering can to avoid disturbing the seeds.
4. Transplant outdoors: Once the danger of frost has passed and the seedlings have developed a few sets of true leaves, they can be transplanted into the garden. Choose a sunny location with well-draining soil for your cardoon plants.
5. Space them out: Cardoon plants can grow quite large, so make sure to give them enough space to spread out. Plant them about 3 to 4 feet apart to allow for their size and to provide good air circulation.
6. Provide support: As cardoon plants grow, they can become top-heavy. To prevent them from toppling over, it’s a good idea to provide some support. You can use stakes or cages to keep the plants upright and prevent them from bending or breaking.
7. Water and fertilize: Cardoon plants like consistently moist soil, so water them regularly, especially during dry periods. They also benefit from regular feeding with a balanced fertilizer to promote healthy growth and abundant leaf stalks.
8. Harvest time: Cardoon plants take about 120 to 150 days to reach maturity. Harvest the young leaf stalks when they are tender and about 8 to 12 inches long. Cut them off at the base of the plant using a sharp knife or pruners.
By following these tips, you should be able to successfully grow cardoon from seed and enjoy a delicious harvest of leaf stalks. Remember to provide them with the necessary care, and you’ll be rewarded with beautiful and tasty plants. Happy gardening!
