Growing directions
Press seeds 1 in deep into cool, well-drained soil and erect support netting before the vines need it. Snow peas are harvested when pods are flat, bright green, and the seeds inside are barely visible; even slight bulging means the pod is overripe for stir-fry use. Keep pods picked daily during peak production to sustain cropping. Avoid high-nitrogen fertilizers, which produce lush foliage at the expense of pods.
