still can't cilantro cut - what am i doing wrong?

if it keeps bolting before you get a decent harvest, that's just cilantro. heat and long days send it to flower fast. pick the outer stems and never take more than about a third at once, give it some afternoon shade, and sow a new pinch of seed every few weeks so there's always a young batch coming. slow-bolt seed helps too. or did you mean it won't regrow after you cut it?
