General Care and Maintenance

Watering

• Provide consistent watering to keep the soil evenly moist. In Colorado’s dry climate, it’s important to monitor soil moisture and water regularly.
• Water at the base of the plants to reduce the risk of leaf wetness and fungal diseases.

Fertilizing

• Incorporate a balanced fertilizer at planting time, especially one high in phosphorus to promote strong root development. Adding compost can also improve soil quality.

Pest and Disease Management

• Keep an eye out for pests such as aphids, slugs, and pea weevils. Since Colorado is typically drier, pest pressure can vary, but vigilant monitoring is key.
• Utilize organic pest control methods and practice crop rotation to prevent disease buildup in the soil.

Harvesting

• Harvest sugar snap peas when they are plump and still tender, typically 60-70 days after planting. Regular harvesting encourages the plant to produce more pods.

Facts about Sugar Snap Peas

Sugar snap peas are a delicious variety of edible pea that combines the sweetness of garden peas with the crunch of snow peas. They are high in vitamins A, C, and K and are known for their crisp texture and sweet flavor. They are typically eaten whole, pods and all, and are a great addition to salads and stir-fries.

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”.
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.
