Coriander Problems, Pests and Diseases

The main problem facing anyone growing coriander is that coriander does have a tendency to bolt straight into flower.  This is where the plant forgets about growing leaves and jumps straight to the flowering stage.  Coriander is relatively fussy in that it doesn’t like to be stressed in any way.  If you fail to water it, or it gets too hot, or it is transplanted, it will bolt.  To be truthful, your coriander will flower reasonably early in it’s life.  This is an inevitability, but there are a few things that you can do to prolong the leaf production phase.  Keep the soil moist, and think about maybe planting in partial shade (although coriander does need a reasonable amount of sun to grow properly).  Coriander is an excellent plant for sowing successionally, so sow regularly every 2-3 weeks.

Coriander can suffer from root rot.  Coriander doesn’t like it’s roots to be too wet so make sure the soil is well-draining and don’t overwater the plants.  Water during the day, and avoid watering in the evening.

Coriander is a very aromatic plant, and as such it is usually free from pests, although slugs may have a chomp at the seedlings.
