FAQs
How long does it take for Coriander 'Calypso' to grow?
Germination typically takes 7-14 days. You can start harvesting young leaves about 4-6 weeks after sowing, with mature harvests following soon after.
Can I grow this indoors?
Yes, Coriander 'Calypso' can be grown indoors in pots on a sunny windowsill. Ensure it receives at least 6 hours of sunlight per day and adequate watering.
What is 'bolting' in coriander?
Bolting refers to when a plant prematurely sends up a flower stalk, which often leads to a bitter taste and cessation of leaf production. 'Calypso' is bred to resist this.
How do I ensure a continuous supply of leaves?
Make successive sowings every 2-3 weeks. Harvest regularly by picking outer leaves, which encourages the plant to produce more.
What is the difference between 'Calypso' and other coriander varieties?
'Calypso' is specifically bred to be slow to bolt and have a cut-and-come-again habit, offering a longer and more reliable harvest than many standard varieties.
Can I eat the flowers if it does bolt?
Yes, coriander flowers are edible and have a milder flavour than the leaves. They are also attractive to pollinators.
Troubleshooting
Plants bolting too quickly
Ensure consistent moisture and avoid planting in excessively hot conditions. Provide some shade during peak heat if necessary.
Yellowing leaves
This can indicate overwatering or lack of nutrients. Check soil moisture and consider a light feed if necessary.
Pests on leaves (e.g., aphids)
Remove pests manually or use a gentle insecticidal soap. Encourage beneficial insects like ladybugs.
Seeds not germinating
Ensure seeds are sown at the correct depth and the soil is kept moist. Check for freshness of seed packet.

Setup, Compatibility & Care
Sowing:

- For a continuous harvest, sow seeds every 2-3 weeks.
Compatibility:
- Thrives in most garden soils and is compatible with standard potting mixes for container gardening.
- Can be grown alongside other herbs or vegetables that have similar light and water requirements.
Care:
- Watering: Keep the soil consistently moist, especially during dry periods. Avoid letting the soil dry out completely.
- Sunlight: Prefers a sunny location but can tolerate partial shade. In very hot climates, some afternoon shade can be beneficial.
- Feeding: Generally, no extra feeding is required if planted in fertile soil. If growth appears weak, a balanced liquid feed can be applied sparingly.
- Harvesting: Begin harvesting leaves when the plant is about 10-15 cm tall. Cut outer leaves first, leaving the inner core to continue growing.
