Planting & Care

Sow Blue Hubbard squash seeds directly in the garden after the last frost date, when soil temperatures have warmed to at least 60°F. Plant seeds 1 inch deep in hills or rows, spacing them according to the recommended distance. Keep the soil evenly moist during germination, which typically takes 7-14 days. Once seedlings emerge, thin to the strongest plants.

Provide consistent water throughout the growing season, especially during flowering and fruit development. Mulching around plants helps retain moisture and suppress weeds. Harvest when the skin is hard and the stem begins to dry and turn brown. Cure the fruits in a warm, dry area for about 10 days before storing in a cool, dry place.
