Starting Sugar Snap Peas Indoors

In Kansas (Zone 6a), start indoor sugar snap pea seed planting between March 1 and March 15. This timeframe allows for healthy seedlings ready for outdoor transplantation by mid-April after the last frost date.

Transplanting Sugar Snap Pea Seedlings

Transplant sugar snap pea seedlings outdoors from April 15 to April 30. Ensure the soil temperature is consistently above 50°F for optimal growth. Space seedlings 2-4 inches apart in rows that are 24-36 inches apart for adequate airflow.

General Care and Maintenance

Watering

  • Maintain consistently moist soil by watering deeply, especially during dry spells in Kansas. This practice helps to support the shallow root systems of sugar snap peas.
  • Avoid overhead watering to minimize leaf wetness, which can lead to disease issues.

Fertilizing

  • Apply a balanced organic fertilizer at planting time and again when the peas start to flower. Composting beforehand can improve soil structure and nutrient content.

Pest and Disease Management

  • Stay vigilant for common pests such as aphids and pea weevils, and watch for mildew, particularly in wetter conditions. Regular monitoring helps in early detection and management.
  • Utilize organic pest control methods to protect your plants while promoting a healthy garden ecosystem.

Harvesting

  • Harvest sugar snap peas when they reach about 3 inches in length and are still crisp. Frequent harvesting encourages continued production.

Sugar Snap Facts

Sugar snap peas are a type of edible pea that is consumed whole, pod and all. They are a cross between snow peas and garden peas, featuring a sweet flavor and crisp texture. High in vitamins A, C, and K, they are also a good source of dietary fiber. Sugar snap peas are typically planted in early spring and are one of the first crops ready for harvest, making them a favorite among gardeners.


In my garden, I try to compost as much as possible so I can mix in the nutrient-rich compost into my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”.
If you don’t have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.

If you are uncertain of the quality of your soil, you can get easy-to-use soil tests at Amazon for 17 dollars. Check latest prices here: Soil testing kit.

Also remember to check out how much sunlight your growing area gets, and that the rain drains well. If you treat your soil well and plan your crops according to your climate you will succeed with any plant you want.

The satisfaction when you harvest your own produce is well worth the time you put in 🙂
