Hi All,
Have grow some coriander but it seemsto have grown very stringy, have gron some in full sun some in semi shade but all are very stringy any ideas

Leggy usually means not enough light (the plant gets leggy trying to find light) or too warm (the plant spurts ahead of where it should be because of the favourable growing conditions). If you have grown in sunny and shady then presumably it is not the light. If you have grown indoors then it could be the warmth otherwise I am short on ideas.

Sometimes cutting back the growth can encourage new dense growth, but I would think twice before doing that – it could also kill it!

Either that or it's bolting - it seems to shoot up when it's about to flower.  How old is it?
