Min qty: 30 seeds

Blue Hubbard Squash is known for its distinctive blue-gray color and large size, weighing in at 10-40 pounds. It is a hard-skinned variety, typically weighing between 10 to 20 pounds, and is grown in North America, particularly in New England.

The history of the Blue Hubbard Squash is believed to have been developed by early Native American cultivators. The squash was likely selected for its high yield and long storage ability, which allowed it to be a valuable food source during the winter months. Over time, the Blue Hubbard Squash became popular among settlers in New England, who adopted it as a staple in their diets.

Today, the Blue Hubbard Squash is still widely grown and consumed, particularly in the Northeast of the United States. It is highly valued for its sweet and nutty flavor, and can be used in a variety of recipes, from soups and stews to baked goods and purees. It's great baked or steamed with brown sugar and butter on top or with maple syrup.

Select a location: Choose a sunny spot in your garden with well-draining soil. Squash plants require plenty of sunlight and good drainage to thrive.

Prepare the soil: Prior to planting, amend the soil with compost or well-rotted manure to improve fertility and water retention. The soil should have a pH between 6.0 and 7.0.

Start seeds indoors: Blue Hubbard Squash is usually started from seed. Sow seeds indoors 4-6 weeks before the last expected frost date in your area. Plant the seeds 1 inch deep in seed starting trays or pots and keep them warm (75-85°F) and moist.

Transplant seedlings: When the seedlings have at least two leaves, transplant them into the garden. Space them 4-6 feet apart, with 8-10 feet between rows.

Water and fertilize: Squash plants require consistent moisture, especially during dry periods. Water deeply once or twice a week, avoiding getting water on the leaves to prevent disease. Fertilize with a balanced fertilizer every 2-3 weeks.

Provide support: As the vines grow, they will need support to keep them off the ground and prevent disease. You can use trellises, cages, or stakes.

Harvest: Blue Hubbard Squash is ready to harvest when the skin is hard and the color is uniform. Cut the fruit from the vine with a sharp knife, leaving a few inches of stem attached. Store in a cool, dry place for up to several months
