When cilantro goes to
seed it's called 'bolting'. Heat often makes it bolt. From what I've read, planting a lot of cilantro together helps to prevent from bolting. The most recommended solution is to
plant it in succession that way once one
plant has bolted, you have another
plant ready for picking. I'm not sure how to collect the
seeds, my cilantro is in a bad spot so I can't just let them fall. I was considering putting a brown bag over the dried
flower clusters and rubberbanding it to the stem. Then wait and see what falls off.
