Step-by-Step Growing Guide
Snap peas are a cool-season crop that must be timed carefully — they germinate in soil as cold as 4°C and perform best between 10–18°C, making them ideal for early spring planting 4–6 weeks before last frost. Direct sow seeds 2–3cm deep and 5–8cm apart along a trellis or netting at least 150cm tall — climbing types easily reach 180cm. Inoculate seeds with Rhizobium leguminosarum bacteria inoculant for improved nitrogen fixation. Snap peas prefer fertile, well-drained soil with pH 6.0–7.0 and require no supplemental nitrogen fertilizer — they fix their own. Phosphorus and potassium support: a light application of rock phosphate or wood ash at planting is beneficial. Water consistently at 2.5–4cm per week — irregular moisture causes peas to develop tough strings. Once temperatures exceed 24°C, production stops and vines decline.
