Planting & Growing Tips
Plant coriander in well-drained soil and water regularly. Coriander prefers cooler growing conditions and tends to flower and go to seed more quickly during warm weather. Keep the soil reasonably moist without waterlogging it. Allowing coriander to become hot or dry can encourage premature flowering, commonly known as bolting. Replant coriander regularly if you want a continuous supply of fresh leaves. Successive plantings every few weeks can help extend the harvest over the cooler months.
Growing Coriander in Pots
Coriander can also be grown successfully in pots and containers. Choose a container with good drainage and position it where the plant receives plenty of light while avoiding excessive heat during warmer weather. Check container-grown coriander regularly for water, as potting mix can dry out more quickly than garden soil.
Companion Planting
Coriander can be planted with parsley, spinach and beans.
Frequently Asked Questions
How can I stop coriander from going to seed too quickly?
Coriander naturally tends to flower and set seed, particularly when conditions become warm or dry. Grow it during the cooler months, keep the soil consistently moist and avoid allowing the plant to become stressed by heat or lack of water. Planting new coriander every few weeks can also provide a continuous supply of fresh leaves.
Can you eat coriander after it starts flowering?
Yes. Coriander is still useful after it begins flowering. The leaves, stems, and roots can be used in cooking, while the plant can also be allowed to develop coriander seeds for culinary use. Flowering does change the plant's focus from producing leafy growth to producing seed, so the leaves may become less desirable if fresh foliage is your main goal.
