I really struggle to grow coriander in my garden. I once grew a different type that only had small thin leaves and produced a lot of seeds but all subsequent attempts have slowly disappeared until completely dead.
I have tried more and less sun, the same with water and always properly drained soil.
I recently tried to grow some plants from seed. They all germinate and grow to about 8cm high but along the way get all spindly. Then they start to die off. They're not infected and the leaves actually look healthy, except the plant doesn't grow enough of them.
What is wrong?
