Know before you grow
The practical stuff.
Ready to pick when
Pods pencil-thick, smooth, and crisp enough to snap in half. Pick before the seeds bulge through the pod wall.
Don't wait: Bulging, lumpy pods are tough and stringy, and unpicked pods shut down new flowers.
Yield
About 0.75 lbs per plant over ~3 productive weeks (~0.75 lb). Re-sow every ~10 days for a steady supply instead of one glut.
