When you do harvest, don’t be a barbarian with a knife. Grasp the stalk near the base, give it a slight twist, and pull gently to the side. It should pop right off with a satisfying snap. This method encourages the plant to grow more stalks, like a vegetable version of “you pull one, I’ll send two friends.” If you cut with a knife, you leave a stump that rots and invites pests—basically leaving the door open for garden vampires.
Always leave at least half the stalks on the plant. You’re a forager, not a conqueror. If you strip the plant naked, it will be too weak to store energy for next spring. Think of it like not eating all the snacks at a party—you want to leave some for the next guest, and that guest is Future You.

The Late Season Surprise: A Second Chance
For the truly adventurous, there is a second harvest window in late summer or early autumn, after it’s cooled down. Some plants will put out a few more tender stalks, but they’re never quite as sweet as the first batch. It’s like finding a forgotten candy bar in your glove compartment—better than nothing, but the wrapper is a little greasy. I once tried this and got exactly three usable stalks, which I used to make a single, very proud-serving-sized crumble. It was delicious, but it was also a lesson in managing expectations.
