Know before you buy
Because of their hard, protective shells, these squash are excellent for long-term storage. When kept in a cool, dry environment between 50-55°F with moderate humidity, they can remain fresh for several months after harvest.
Blue Hubbard vines are vigorous and require significant room to spread. You should space your plants 36-48 inches apart to ensure they have enough airflow and soil nutrients to support their large fruit.
The flesh is firm, dry, and yellow, making it ideal for roasting, baking, or using in soups and pies. Its dense texture holds up well during cooking, so it is best suited for recipes that require a substantial, non-watery base.
Yes, these are certified organic seeds. They are grown and processed without the use of synthetic fertilizers or pesticides.
You should harvest your squash approximately 102 days after planting, ensuring you bring them in before the first heavy frost. Look for a hard, dull rind that resists puncture from a fingernail to confirm maturity.
While you can start them indoors, they thrive when direct-sown into warm, fertile soil once the danger of frost has passed. Ensure your soil temperature is consistently between 70-85°F for the best germination results.
