Starting Sugar Snap Peas Indoors

In North Dakota (Zone 4a to 4b), begin indoor sugar snap pea seed starting around March 15 to April 1. This timeline allows for sturdy seedlings that can be transplanted outdoors by mid to late April, after the danger of frost has diminished.

Transplanting Sugar Snap Pea Seedlings

Transplant sugar snap pea seedlings outdoors from April 15 to May 1, ensuring the soil is workable and moist but not overly saturated. Space the seedlings 2 to 3 inches apart in rows with at least 18-24 inches between rows for optimal growth and air circulation.

I have had great success sowing the sugar snaps peas directly in the ground When its warm temperature forcast of rain coming. I put the seeds about a half inch down in the soil. The plants will start growing fast about a week after.

General Care and Maintenance

Watering

  • Provide consistent and adequate watering to maintain evenly moist soil. Regular rainfall in North Dakota typically supports moisture needs, but supplemental watering may be necessary during dry spells.
  • Water at the base of plants to promote root health and prevent frogy soil conditions.

Fertilizing

  • Apply a light application of balanced fertilizer at planting time and again when the flowers begin to form. Incorporating compost into the soil can significantly boost nutrient levels.

Pest and Disease Management

  • Regularly inspect for common pests such as aphids and root maggots. Given the temperature fluctuations in North Dakota, vigilance against both pests and diseases is crucial.
  • Utilize organic gardening practices and crop rotation to manage pests and diseases effectively.

Harvesting

  • Harvest sugar snap peas when they are crisp, tender, and their pods are fully developed. Frequent harvesting encourages more pod production and keeps the plants healthy.

In my garden, I try to compost as much as possible, so I can mix in the nutrient-rich compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”.
