Garden Pea in May: monthly care

Garden peas thrive in full sun or partial shade and prefer loam or clay soil that is moisture-retentive but well-drained. Before sowing, prepare the bed by digging in well-rotted compost or manure to improve soil structure and fertility. Peas are legumes and fix their own nitrogen, so avoid overly rich soil which encourages leafy growth at the expense of pods. The soil pH should ideally be neutral to slightly alkaline. Sow peas directly outdoors from March through to May, once the soil temperature reaches at least 10°C. Earlier sowings in March may benefit from cloche protection or fleece if frost threatens. Create a shallow drill about 4–5 cm deep and space seeds 8 cm apart in the row. If you're planting in double rows for mutual support, space the rows about 20 cm apart, with 60–90 cm between each pair of rows depending on the variety's eventual height. After sowing, backfill the drill and firm the soil gently. Water the row thoroughly if the soil is dry, but avoid waterlogging. Peas germinate in 7–14 days depending on temperature. As soon as seedlings emerge, protect them from birds using netting or pea guards—pigeons are particularly fond of young pea shoots. Install support structures early: taller varieties (100–150 cm) need sturdy canes, netting, or pea sticks, while dwarf types (50–70 cm) manage with shorter twiggy branches or low netting. Mulch lightly around the base once plants are established to conserve moisture and suppress weeds.

Garden peas have moderate water needs and perform best with consistent moisture, especially once flowering begins in spring and during pod formation in early summer. Water at the base of plants during dry spells, aiming for a deep soak once or twice a week rather than frequent shallow watering. Mulching with compost or straw helps retain soil moisture and keeps roots cool. Avoid overhead watering in humid conditions, as wet foliage encourages mildew. Peas fix atmospheric nitrogen through root nodules, so additional feeding is generally unnecessary and can be counterproductive—excess nitrogen promotes lush leaves at the expense of flowers and pods. If your soil is very poor, a light application of a balanced general-purpose fertiliser at planting time is sufficient. There are no specific feeding months listed for peas, reflecting their low nutrient demands. Peas are hardy annuals tolerant down to zone 3a, so overwintering is not relevant for spring-sown crops. However, autumn-sown varieties (not covered here) can overwinter outdoors in milder zones with cloche protection. Common pests include pea moth, whose larvae tunnel into pods from June onwards—early sowing or using fine mesh netting during flowering can reduce damage. Aphids cluster on shoot tips and can spread virus diseases; squash small infestations by hand or use an organic soap spray. Pea weevil notches leaf edges but rarely causes serious harm. Powdery mildew is the most frequent disease, particularly in dry conditions or on late sowings; ensure good spacing, water adequately, and remove affected foliage promptly. Mice and birds are persistent problems at sowing and seedling stage—protect seeds with netting or traps as needed.
