Tromboncino Squash is a distinctive Italian heirloom from the Cucurbita moschata family, celebrated for its long, gently curved fruits and bulbous blossom end. Harvest the tender fruits young as summer squash for a mild, sweet, nutty flavor, or allow them to mature for a firmer winter-squash-style harvest. The vigorous vines perform especially well when trained on a sturdy trellis, bringing an abundant and eye-catching crop to the garden.

Why Choose Tromboncino Squash?

• Distinctive Italian Heirloom: Produces uniquely shaped, elongated fruits with a characteristic bulbous blossom end.
• Dual-Stage Harvest: Pick young for tender summer squash or allow fruits to mature for a firmer winter-squash-style harvest.
• Mild, Nutty Flavor: Young fruits have a delicate flavor that works well in fresh, grilled, sautéed, roasted, and stuffed dishes.
• Vigorous Vines: Productive plants can provide an extended harvest when given warmth, fertility, water, and regular picking.
• Trellis-Friendly Growth: Train the vines vertically to keep long fruits cleaner and make them easier to spot and harvest.
• Open-Pollinated Heirloom: A traditional variety valued for its unusual appearance, kitchen versatility, and seed-saving potential.
• Non-GMO Seeds: Produced through traditional breeding methods without genetic modification.

Planting Tips for Success

• When to Plant: Direct sow outdoors after the last frost when soil and weather are consistently warm. Squash does not tolerate cold soil or frost.
• Sunlight: Plant in full sun with at least 6–8 hours of direct sunlight each day.
• Soil: Choose fertile, well-drained soil enriched with compost or other organic matter.
• Planting Depth: Sow seeds approximately 1 inch deep and keep the soil evenly moist until seedlings are established.
• Spacing: Give plants generous room for their vigorous vines, or train them up a sturdy trellis to use vertical space.
• Support: Install strong support before the vines become large. Use soft ties or slings to support developing fruits if needed.
• Watering: Water deeply and consistently at the soil line, especially during flowering and fruit development. Mulch can help conserve moisture.
• Fertilizing: Incorporate compost before planting and apply a balanced fertilizer according to label directions. Avoid excessive nitrogen that encourages leaves over fruit.
• Harvesting: Pick young fruits regularly while they are tender and manageable. For a mature harvest, leave selected fruits on the vine longer and allow the skin to harden before harvesting ahead of frost.
