This is my second year to grow cilantro, and again, it is not doing well. Everyting else I plant does relatively well. Last year my sister helped herself and took some and after that, I did not have any more. This year, a little better luck, but not much. The leaves are small and thin. I snapped off the flowers, hoping to encourage growth, but it did not help much. Any suggestions? I do not know what it needs - wet or dry, hot or cool. I assume hot and maybe dry as I associate it with Mexico. Thanks.
