FAQs
When is the best time to sow Coriander Calypso seeds?
You can sow seeds directly outdoors from April to July for a continuous supply. For overwintering, sow in late summer.
How far apart should I space the coriander plants?
Sow seeds in rows 30cm (12") apart and thin seedlings to 23cm (9") apart once they are large enough to handle.
My coriander is flowering very quickly. What can I do?
Coriander can bolt if stressed by heat or lack of water. Ensure consistent watering and remove flowering stems immediately to prolong leaf production.
Can I grow this indoors?
While best grown outdoors, you can attempt to grow it indoors in a sunny windowsill, ensuring consistent moisture and light. However, outdoor cultivation generally yields better results.
How many seeds are in a packet?
Each packet contains approximately 150 coriander seeds.
What are the mature plant dimensions?
The plant typically reaches a height of up to 40cm (15.7in) and spreads up to 25cm (9.8in) when fully established.
Can I eat the flowers or seeds?
While the primary use is for foliage, the flowers are edible and can be used as a garnish. The seeds are the source of ground coriander spice, but this variety is optimized for leaf production, so seed yield may vary.
Troubleshooting
Seedlings not appearing
Ensure seeds were sown at the correct depth (1cm) and the soil is kept consistently moist. Check if the sowing conditions meet the light requirements.
Plants bolting (running to seed) too quickly
Ensure the soil is kept consistently watered, especially during dry or hot weather. Consider providing some light shade during the hottest part of the day if bolting is persistent.
Poor leaf growth or yellowing
Check soil fertility and drainage. Ensure the plants are receiving adequate sunlight (at least 6 hours daily). Consistent watering is also key.
Pests on leaves
Inspect plants regularly for common garden pests. Handpick larger insects or use an appropriate organic pest control method if necessary.

Setup, Compatibility & Care
Sowing:
- Prepare a light, well-drained, fertile soil in a sunny position. Rake to a fine tilth.
- Direct sow seeds thinly at a depth of 1cm (1/2") in rows spaced 30cm (12") apart.
- Sow outdoors from April to July for main season crops. For winter use, sow in late summer.
Thinning:
- Once seedlings are large enough to handle, thin them to stand 23cm (9") apart to allow adequate space for growth.
Watering:
- Keep soil consistently moist, especially during warmer periods, to prevent premature bolting.
Harvesting:
- Harvest outer leaves as needed once the plant is established.
- Remove any flower stems that appear to encourage continued leaf production.
Protection (for winter sowing):
- Use a cloche or cold frame to protect plants sown in late summer for winter harvests, ensuring they receive full light.
