Ease of Cultivation and delicious flavor: Waltham Butternut squash is a beloved winter variety known for its sweet, nutty flavor and creamy texture. It is relatively easy to grow, making it an excellent choice for both novice and experienced gardeners. This variety thrives in warm temperatures and is ideal for baking, roasting, or pureeing, adding a delightful taste to soups, pies, and side dishes.

Direct Sowing: For direct sowing, plant Waltham Butternut squash seeds outdoors after the last frost date when the soil temperature has warmed to at least 70°F. Sow the seeds about 1 inch deep and 3-4 feet apart in rows that are 5-6 feet apart. Germination typically occurs within 7-14 days. Ensure the soil is consistently moist, and consider applying mulch to retain moisture and suppress weeds. The plants will require ample space to spread, so ensure proper spacing during planting.

Early Sowing for Seedlings: For an early start, sow seeds indoors 4-6 weeks before the last expected frost. Use seedling trays filled with high-quality potting mix, placing 1-2 seeds per cell. Maintain a temperature between 70-75°F for optimal germination. Once the seedlings have developed at least two sets of true leaves and the danger of frost has passed, transplant them into the garden, spacing them 3-4 feet apart. Water the transplants well after planting and apply mulch to help retain moisture and control weeds.

Harvesting: To determine when Waltham Butternut squash is ready for harvest, look for fruits that have turned a deep tan color and have hard skin, typically 90-100 days after sowing. The stem should also begin to dry and turn brown. Harvest the squash before the first frost, as cold temperatures can damage the fruits. Use a sharp knife or pruners to cut the squash from the vine, leaving a few inches of stem attached to enhance storage longevity.
