From selecting varieties to harvesting a delicious crop, here’s how to grow coriander in pots.

How to sow coriander seeds in pots
Soak a handful of seeds overnight in a shallow dish filled with water. When you are ready to sow the coriander seeds fill a plant pot with good quality potting soil.
'It is best to use a premium, well-draining potting mix enriched with organic matter like compost or peat moss. Coriander is vulnerable to root rot, a fungal disease that can cause the roots to decay, making it essential to use a potting mix that promotes proper drainage,' says Josh Neville.
Sow the tiny coriander seeds thinly by sprinkling them at the top of the soil. Lightly press down so they are just covered in soil up to about 1cm deep. Water the soil so it is damp (not soggy).
Growing coriander herbs need at least 6 hours of daylight per day to thrive so place them in a light spot such as a kitchen window or a part-shaded patio.
'Germination takes between 14 and 21 days and the pots can be kept either inside or outside,' explains Fiona Jenkins at Myjobquote.co.uk.
'I've found that coriander thrives in cooler positions with some light shade. It's crucial to maintain well-drained soil and avoid direct sunlight, especially during the scorching summer months,' adds Ash Read from Indoor Plants.
How to care for growing coriander in pots
It’s important not to over-water coriander, however, you do need to keep the soil moist. Continue to water the pot once or twice a week as the soil begins to dry out.
'Each seed will germinate in about one to three weeks with moderate light, warmth and moisture. From that point it will generally take around 50-60 days to mature,' explains Tanya Anderson of Lovely Greens.
To encourage robust and healthy growth when growing coriander in pots apply a balanced liquid seaweed fertiliser every few weeks.
How to harvest coriander in pots
Once the pot has a healthy head of green coriander leaves you can pick or snip off the herb as needed for culinary dishes. Take mature leaves from the outside and snip off the coriander at the base of the stem. The stalks are edible and full of flavour too.
'With cilantro, you can also do the lawn mower technique,' says Kevin Espiritu from Epic Gardening. 'So take a nice and mature clump and lawn mower it down. Don’t go too low and just clump the whole thing off. It’s a good way to stop the flower stalks from even forming and get a nice continual harvest.'
FAQs
When is the best time to plant coriander in pots?
'If growing outside, direct sow small batches of seeds into containers of loam-based compost every two weeks from March until the end of August,' advises Thompson & Morgan horticultural expert, Annelise Brilli.
Indoors, the herb will last further into autumn and sometimes even winter.
How long will a coriander plant last?
According to the Royal Horticultural Society (RHS), coriander is an annual plant and so will die during winter. They stop producing edible leaves when they start to flower. Discourage flowering with regular picking. If doing a large harvest to store ensure you allow coriander in pots to recover for a few weeks before harvesting again.
'Cilantro has a short life because it bolts (flowers prematurely) in high heat. However, that can be prolonged by choosing a variety that handles high temperatures. Our favourite choices are Calypso, Marino and Santo varieties,' says Kevin Espiritu.
'For a continuous supply of coriander leaves sow seeds every 3 to 4 weeks,' adds Fiona Jenkins.
