Direct sow pea seeds into prepared, well-drained soil in early spring, typically 4-6 weeks before the average last frost date, as soon as the soil is workable (minimum 4°C/40°F). Plant seeds 2-5 cm (1-2 inches) deep and 5-10 cm (2-4 inches) apart. For fall crops, sow in late summer.

For most varieties (except dwarf bush types), provide support like trellises, netting, or twiggy branches at planting time or very soon after germination. Peas use tendrils to climb.

Maintain consistent soil moisture, especially crucial from flowering through pod development. Aim for about 2.5 cm (1 inch) of water per week, adjusting for rainfall. Avoid letting the soil dry out completely, but also prevent waterlogging.

Once seedlings reach about 10-15 cm (4-6 inches) tall, apply a layer of organic mulch (such as straw, shredded leaves, or compost) around the plants. Mulch helps conserve soil moisture, suppress weeds, and keep roots cool.

Keep the area around young pea plants free from weeds, which compete for water, light, and nutrients. Cultivate very shallowly to avoid damaging the peas' shallow roots, or rely on mulch for suppression.

Peas are legumes and fix atmospheric nitrogen, reducing the need for nitrogen fertilizer. Incorporating compost before planting is beneficial. If soil is very poor, a light application of low-nitrogen, high-phosphorus fertilizer might be helpful at planting time.

Keep an eye out for common pea pests like aphids and pea weevils, and diseases such as powdery mildew and root rot. Good air circulation and crop rotation are key preventative measures.

Begin harvesting based on the variety type: Shelling peas when pods are plump; Snow peas when pods are long but still flat; Snap peas when pods are plump and crisp. Pick pods frequently (every 1-3 days) to encourage continued production.
