I need some advice!! I've nurtured some coriander plants from seed and they're now in a pot on my kitchen windowsill. All was well, I'd been using it in curries etc, but now the plants are really tall (around 40cms?) and the leaves are changing shape with every new sprouting. They're not a lot more whispy and look 'ferny', and are not as pungent. I havent cooked with any of these new leaves yet. Also the stalks and leaves are growing more and more pale (yellow/whitish)
Now this afternoon I get home from work and there are flowers on the plant! small, white flowers. What's going on!? Please someone help!
My understanding (I've been gardening for a whole 8 months now) is that bolting can be caused by underwatering. But coriander has a limited lifespan when domesticated, so you have to re-seed every few months.
as Kathy says keep the bolted ones for seed, and sow some new ones for leaves. really organised radio presenters claim to sow things like coriander every couple of weeks so there is always fresh stuff on the go. The bolted ones sound as if they might appreciate some fresh compost as they are getting a bit pale and weedy, but they will probably hold out if you can't be bothered
wow you lot really know your stuff! Thanks again. I think I'll leave them be and keep the seeds... and grow some more in the meantime. I've just got through a new batch of herbs to sow so i'll do them all at the same time
