Step-by-Step Planting & Propagation
To begin growing Blue Hubbard squash, consider starting seeds indoors about 3-4 weeks before the last frost date. Once seedlings have a few sets of true leaves, harden them off before transplanting them into the garden. Plant them in hills or mounds about 3 feet apart to allow for good air circulation and sprawling space.
- Seed Selection: Use certified seeds from a reputable supplier.
- Soil Preparation: Amend garden soil with well-rotted manure or compost before planting.
- Sowing: Direct sow ½ inch deep if temperature allows, or plant indoors in biodegradable pots.
- Spacing: Space hills about 3 feet apart in rows spaced 6 feet apart.
