When to sow coriander?
- Botanical name
- Coriandrum sativum
- Family
- Apiaceae
Coriander is sown outdoors from April to September, 1 cm deep. It is harvested from June to October.
Coriander is an annual plant. The edible parts are the stems, leaves, flowers and seeds.
For leaves the plants are left at 10 centimetres, for seed they are thinned to 20 centimetres. The seed stays on the plant until it turns brown.
Coriander makes no new leaves after cutting. Fresh leaves through the whole season therefore come only from new sowings.
Too much water costs coriander its flavour, and in wet ground it grows poorly.

Pests and diseases
Listed here is every problem for which the sources name this plant as a host. The problems are not listed in order of how common they are.
- Signs
- Colonies of small aphids sit on the shoot tips and the underside of the leaves. The leaf curls and puckers, and sticky honeydew is left on everything below. The viruses they carry are more dangerous than the feeding itself.
- Prevention
- Go easy on nitrogen, because soft sappy growth is what aphids are looking for. Encourage the predators (ladybirds, lacewings, parasitic wasps). Use a reflective mulch, which puts them off settling, and a strong jet of water to knock the colony off the tips.
- What to do
- Potassium soap works on contact and only while it is wet, so it has to reach the underside of the leaf. On drought-loving plants and in heat it can scorch, so apply it in the evening.
- Signs
- Holes appear in the middle of the leaf rather than along the edge, young plants are eaten down to the ground, and there are slimy trails in the morning. On low-growing fruit there are gnawed pits.
- Prevention
- Remove the hiding places beside the bed: boards, stones, dense weeds. Water in the morning and not in the evening, so that the night is dry. Spread a band of coarse sand or gravel around the bed. Cover young plants with fleece. Pick them off at night, which is still the most effective measure.
- What to do
- Baits with iron phosphate are held to carry less risk for pets and children. Put them out in bands beside the bed, not scattered over the whole surface.
Check the registration and the label before use.
