During the last two or three years, I have grown very fond of cilantro in numerous dishes. About three years ago I planted some and was disappointed to find that my plants did not grow any leaves that resembled the herb I buy in the supermarket. I cut the stalks off (just like I do with basil) and to my surprise, instead of growning again they turned to sticks and didn't grow anymore. The next years I tried not cutting them but they just kept on growing taller - but did not grow any nice broad leaves. Then they bloomed but still didn't grow any nice leaves so I eventually threw them out. Any advice on how to grow and also, (very important) how to harvest?
It appears your cilantro is 'bolting' , flowerind and going to seed. Like parsley, cilantro has a tap root and needs a long growing season. Try sowing in late March. Good luck!
