When Are Peas Ready to Pick?

Garden peas have the shortest window of peak quality of almost any vegetable. The sugars that make a freshly-shelled pea sweet begin converting to starch within hours of the pod reaching maturity. This is why shop-bought peas never taste the same as those eaten straight from the garden — supermarket peas have already lost much of that sugar. Getting the timing right at home makes all the difference.

Shelling Peas: Feel the Pod

For traditional shelling varieties — Alderman, Hurst Green Shaft, Kelvedon Wonder — the pod should feel well filled but not stretched tight. Run your fingers along the outside; individual peas should be distinct but not pushing hard against the pod skin. Pop one open: the peas inside should be bright green, plump, and round. If they are pale and starchy-looking, wait another day. If the pod is beginning to yellow or the peas have flattened where they press together, harvest immediately — you are at the edge of the window. Taste one. That sweetness tells you everything.

Mangetout: Harvest While Flat

Mangetout — meaning "eat all" — are harvested when the pod is flat and the peas inside are just beginning to form tiny bumps. At this point the pod is tender and sweet. Once the peas swell to more than pea-sized, the pod becomes fibrous and loses its characteristic snap. Check mangetout plants every two days and pick all pods that show any visible pea development. A mangetout left to mature fully is not wasted — it can be shelled as a small but perfectly good pea.

Sugar Snap Peas: Between the Two

Sugar snap peas are harvested when the pod is fully rounded and plump, but still bright green and crisp. Unlike mangetout, you want the peas inside to be fully developed — the pod itself stays sweet and edible even when round. Press on the pod: it should snap with a crisp sound, not bend. If the pods have started to yellow or the pod strings are tough, you have waited too long. Sugar snaps are eaten whole, pod and all, so sweet crunchiness in the pod is the primary goal.

How to Pick Peas Without Damaging the Plant

Support the vine gently with one hand and use the other to snap or cut the pod at the point where it attaches to the stem. Pulling hard risks dislodging the tendril supports and tearing the main stem. Scissors or small snips make the job faster on a productive vine. Pick from the bottom of the plant upward — lower pods mature first. Regular picking keeps the plant producing; once seed sets are left to mature and dry, the plant reads its job as done and slows or stops flowering.
