Growing Tips, Tricks, and FAQs

Growing Tips

Crespo Squash thrives in rich, well-draining soil with plenty of full sun. For maximum yield and flavor, feed plants monthly with balanced organic fertilizer and mulch heavily to retain moisture and suppress weeds. Watch for common squash pests and rotate planting areas annually to prevent soil-borne diseases. The warty texture is natural and beautiful—embrace it!

When to Grow

Start seeds indoors 3–4 weeks before your last frost date, or direct sow outdoors once soil temperatures consistently reach 65°F or higher. In warmer regions, a midsummer planting can yield a late-fall harvest. Not sure about your frost dates? Check our blog post “Our Experts Answer Questions, Share Resources” for easy local guidance.

How to Sow and Plant

Sow seeds 1 inch deep in nutrient-rich, loose soil. Space plants 36–48 inches apart to give vigorous vines room to spread. Mound planting improves drainage and warms the soil faster. Water thoroughly after planting and keep soil evenly moist (but not waterlogged) during germination and early growth.

How to Grow

Once seedlings are established, thin to the strongest plants. Train sprawling vines across the ground or up sturdy trellises to save space and improve air circulation. Water deeply and consistently, especially during flowering and fruit development. Harvest when the rind is firm, the stem begins to brown, and the fruit sounds hollow when tapped—perfect for storage and winter use.
