Bolting. Heat hits a threshold and the plant switches from leaf to seed — no stopping it once the signal fires.

You don't lose cilantro to bad care. You lose it to the calendar you weren't reading yet.

Zone 7b, June — you're right in the window. Daytime highs in the 90s, soil temperature climbing. The plant reads that as "time is short, make seed."

Succession planting buys you a few more cuts. Shade cloth in the afternoon can delay the signal by a week or two. But the real answer is knowing the season has already turned and planting the next round before this one bolts.

You already know the rhythm. You just weren't naming it yet.

The bolt is the plant telling you it's done. The bitterness is the memory of the window you missed. Succession is the practice of staying ahead of that signal instead of mourning it.

Then the pattern held. No shame in that — the season doesn't negotiate.

What matters is that you see it now. Next year you'll be reading the heat accumulation before the plant commits to seed. That's the difference between losing cilantro and managing the window.

That's a real adjustment. Shade cloth or a building casting shadow in the hottest part of the day — either way, you're buying yourself time.

The plant still senses the day length and soil temp, but lowering the leaf temperature can delay the signal by a week or more. That's an extra cutting or two before the switch flips.

Did it make a difference this year?

That's a win. The shade bought you time — the plant still read the season, but it took longer to commit.

Now you know the lever works. Next year you can stack it: shade plus an earlier succession planting in a different spot, so the second round is already sizing up before the first one finishes.

That's the read.

Same plant, same season, same soil — but the relationship changes when you stop fighting the pattern and start working with the window it gives you.

You're not growing cilantro anymore. You're growing the timing.

I don't dislike anything.

But I can tell you this: a wasp on a watermelon flower is doing more for your fruit than you realize. They're pollinators. Not as efficient as bees, but they show up when it's hot and the bees have gone home.

Most people swat them. The ones who notice what they're actually doing get more melons.

That's the kind of noticing that turns a good grower into one who doesn't have to fight the system.

You're already looking. That's the hard part.

If you're after super hots specifically, call ahead — not every nursery carries them, and the ones that do move through them fast. Ask if they stock by phenology, not calendar. That's your filter.
