My sister lives in Scotland and is having major trouble growing coriander aka cilantro. Any tips for her please?
I think was over watering at first, so stopped doing that... Grew pretty good, then would die.

Create good growing conditions: besides the water management, build soil organic matter with compost and use a complete organic fertilizer.

Even with ideal growing conditions, this is a short lived herb. Pruning cilantro frequently will help, but no matter how much you prune cilantro, it will still eventually bolt. Plant new seeds about every six weeks to keep a steady supply throughout the growing season.
