Starting Sugar Snap Peas Indoors

In New Hampshire (Zone 5a to 6a), start indoor sugar snap pea seed starting between March 15 and April 1. This timing enables robust seedlings ready for outdoor planting between April 15 and May 1, once any danger of frost has passed.

Transplanting Sugar Snap Pea Seedlings

Transplant sugar snap pea seedlings outdoors from April 15 to May 1, ensuring the soil temperature is consistently above 45°F. Space the seedlings 2-4 inches apart in rows with at least 18-24 inches between rows to encourage optimal growth.

General Care and Maintenance

Watering

  • Provide consistent watering to maintain evenly moist soil; New Hampshire’s rainfall can fluctuate, so additional watering might be necessary during dry spells.
  • Water at the soil level to avoid wetting the foliage, reducing the risk of fungal diseases.

Fertilizing

  • Apply a balanced fertilizer at planting and when flowering begins. Adding compost to the soil before planting can significantly improve soil fertility and structure.

Pest and Disease Management

  • Regularly check for common pests like aphids, pea weevils, and powdery mildew. Vigilance is critical, especially during humid summer months.
  • Utilize organic pest control methods and crop rotation to protect sugar snap pea plants from pests and diseases.

Harvesting

  • Harvest sugar snap peas when they are firm and plump, just before the seeds start to swell. Frequent harvesting encourages ongoing production and prevents over-mature peas.

In my garden, I ensure to plant sugar snap peas in well-drained, nutrient-rich soil for optimal growth. They thrive in cooler weather and can be planted early in spring, sometimes even late winter.
