Sowing and Growing Guide
Squash Waltham Butternut
Indoor Sowing
- Start seeds indoors 3-4 weeks before the last expected frost date.
- Fill seed trays with seed starting mix and sow seeds 1 inch deep, 2-3 seeds per cell.
- Keep the soil moist and maintain a temperature of 70-85°F for optimal germination.
- Seedlings should emerge in 7-10 days.
- Once seedlings have developed their first true leaves, thin them to one per cell.
- Transplant seedlings outdoors when all danger of frost has passed and soil temperature has reached 60°F.
Outdoor Sowing
- Sow seeds directly into the garden after all danger of frost has passed and soil temperature has reached 60°F.
- Choose a sunny location with well-draining soil.
- Sow seeds 1 inch deep and 3-4 seeds per hill, spacing hills 4-6 feet apart.
- Water well after sowing and keep the soil consistently moist.
- Once seedlings have emerged, thin them to the strongest plant per hill.
Growing
- Waltham Butternut Squash thrives in full sun and fertile, well-draining soil.
- Water deeply and regularly, aiming to keep the soil evenly moist but not waterlogged.
- Mulch around the plants to help retain moisture and suppress weed growth.
- Provide support for the vines, such as trellises or stakes, to keep the fruits off the ground.
- Fertilize the plants with a balanced fertilizer every 4-6 weeks.
- Harvest the butternut squash when the skin is hard and the fruit has turned fully tan.
