Coriander: FAQs & Common Problems
Coriander FAQs
Harvest coriander leaves regularly once the plant reaches about 15cm tall, snipping leaves as needed. Frequent picking encourages bushier growth, but avoid removing more than one-third of the plant at a time. Leaves are best harvested before the plant flowers for peak flavour.
Coriander grows well in containers at least 20cm deep to accommodate its taproot. Use a peat-free multipurpose compost and ensure the container has good drainage holes. Avoid waterlogged conditions to prevent root rot.
Coriander benefits from a light feed of balanced liquid fertiliser every 2–3 weeks, especially if grown in pots. Avoid high nitrogen fertilisers, which can encourage leaf growth but may reduce flavour and aroma. Water before feeding to avoid root scorch.
Keep coriander soil consistently moist, particularly during hot, dry spells. Water when the soil is dry to the touch, but avoid soaking as plants dislike sitting in wet conditions. Mulching can help retain soil moisture.
