Frequently Asked Questions

What pest or disease most often affects Pisum sativum (garden peas) and how can I control it?

Watch for powdery mildew and pea aphids during warm, humid spells and as plants get dense. Remove badly affected leaves early and improve airflow by avoiding overhead watering; for aphids, blast them off with a strong jet of water and use insecticidal soap if numbers are increasing on new growth. If mildew becomes widespread, stop watering leaves and mulch to reduce soil splash, since spores spread easily from splashed dirt.

How often should I water Pisum sativum during the main growing phase?

During flowering and pod fill (roughly the middle of the season), keep soil evenly moist—about 1 inch (2.5 cm) per week total, split into smaller waterings as needed. Water deeply when the top 1–2 inches (2.5–5 cm) are dry, because peas develop poorly if they dry out and then are soaked again. Aim water at the soil line, not the leaves, to reduce mildew.

How do I tell when Laxton's Progress No. 9 garden peas are ready to harvest?

Harvest when pods are fully filled but still tender: pick when peas inside are about the size of a small marble and the pods feel firm, not bulging. Start harvesting once pods begin maturing (around 70 days from sowing) and pick every 1–2 days, because delaying harvest quickly turns peas starchy and less sweet. Use or shell the same day for the best flavor and texture.
