Ease of Cultivation and deliciously sweet flavor: Waltham Butternut is a popular winter squash variety renowned for its sweet, nutty flavor and smooth, creamy texture. This vegetable is relatively easy to grow, making it an excellent choice for home gardeners. With its robust growth habit, it can yield a generous harvest, and the fruit can be stored for long periods, allowing for enjoyment throughout the winter months.

Direct Sowing: For direct sowing, plant Waltham Butternut seeds outdoors after the last frost date, once the soil temperature has warmed to at least 70°F. Sow seeds 1 inch deep and 3-4 feet apart in rows that are 5-6 feet apart. Germination typically occurs within 7-14 days. Keep the soil consistently moist, especially during dry periods, and consider using mulch to retain moisture and control weeds. As the plants grow, they will need adequate space to spread, so ensure proper spacing for healthy growth.

Early Sowing for Seedlings: For an earlier start, sow seeds indoors 4-6 weeks before the last expected frost date. Use seedling trays filled with a good-quality potting mix, placing 1-2 seeds per cell. Maintain a temperature of 70-75°F for optimal germination. Once seedlings have 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 mulch around them to conserve moisture and suppress weeds.

Harvesting: To determine when to harvest Waltham Butternut squash, look for fruits that have turned a deep tan color and have a hard skin, typically 75-100 days after sowing. The stems should be dry, and the squash should feel firm to the touch. It’s best to harvest before the first frost, as freezing temperatures can damage the fruit. Use a sharp knife or pruners to cut the squash from the vine, leaving a few inches of stem attached to improve storage longevity.
