Long Island Cheese Squash Recipe: Sunny Garden Harvest in 60 Days

Growing Long Island Cheese squash delivers that sunny, golden harvest in just 60 days—the perfect summer squash for busy gardeners who want reliable, flavorful results. 🌱 I’ve grown this variety for years, and it’s become a staple in my garden because it thrives even when I forget to water (a little).

The secret lies in its compact growth habit and quick maturity, making it ideal for small spaces or containers. This variety loves warm soil and full sun, so time your planting after the last frost when temperatures consistently stay above 60°F.

Well-draining soil rich in compost ensures sweet, tender squash without the bitterness some varieties develop. Water consistently—about 1 inch per week—but avoid soggy soil, which can lead to blossom-end rot.

By mid-summer, you’ll be harvesting 3-5 inch squash with a creamy, buttery texture that’s perfect for grilling, stuffing, or sautéing. The plants produce prolifically, giving you a steady supply for 4-6 weeks of peak harvest.

Just watch for squash bugs and cucumber beetles, which love this variety—neem oil or row covers can help keep them at bay. Whether you’re a first-time gardener or a seasoned grower, Long Island Cheese squash is a foolproof choice.

It’s disease-resistant, productive, and forgiving—exactly what you need for a stress-free summer harvest. Let’s get those seeds in the ground!

Step-by-Step guide to growing Long Island Cheese squash

Here's how to grow these sweet, prolific squash from seed to harvest in just 60 days.

Fill 2-inch deep seed-starting cells with sterile potting mix and plant 2-3 seeds per cell at a depth of 1 inch. Cheese squash germinates best at 80-90°F, so use a seedling heat mat if your home runs cooler. Keep the soil consistently moist but never soggy—you'll see sprouts in 7-10 days.

Once seedlings emerge, remove the weakest one to leave the strongest plant per cell. Place under grow lights for 12-14 hours daily to prevent leggy growth. You'll know they're ready for transplant when they have 2-3 true leaves and sturdy stems.

Two weeks before your last frost date, begin hardening off by placing seedlings outside in partial shade for 1-2 hours daily, gradually increasing exposure. Cheese squash thrives in full sun and warm soil, so wait until soil temperatures reach 60°F before transplanting.

Choose a location with 6+ hours of direct sun and well-draining soil. Space plants 3-4 feet apart in hills—mound soil into small pyramids and plant 3-4 seeds per hill at 1 inch deep. Thin to the strongest plant per hill after 2 weeks when seedlings are 4 inches tall.

Water deeply 1-2 times weekly, keeping soil 1-2 inches moist at all times. Mulch with 2-3 inches of straw to retain moisture and suppress weeds. Cheese squash is heavy feeders, so side-dress with compost or balanced fertilizer when vines begin running.

Watch for yellowing leaves—this signals either overwatering or nutrient deficiency. If leaves curl upward, your plants need more water; if they wilt in heat, provide afternoon shade. You'll see male flowers first, followed by female flowers (with tiny squash forming at the base) in 4-5 weeks.

Harvest when squash reach 6-8 inches long and develop a smooth, creamy yellow skin. Use a sharp knife or pruners to cut stems, leaving 1 inch of stem attached to prevent rot. Check plants every 2-3 days—unharvested squash will grow rapidly and lose sweetness.

Store in a cool, dry place for up to 2 weeks or use immediately in recipes. The more you harvest, the more your plants will produce—expect 8-12 squash per plant under ideal conditions. Save seeds from your best specimens for next year's garden!

Tips & tricks for growing perfect Long Island Cheese squash

Here's what I've learned after growing these sweet, prolific squash for years—tricks that'll help you avoid common pitfalls and maximize your harvest.

Seed Starting: The 80-90°F germination temperature is critical—if your home runs cooler, invest in a seedling heat mat. I've found that pre-warming the potting mix in the microwave for 30 seconds before planting also gives those seeds a head start. And here's a pro move: label your seed-starting cells with the planting date—this helps track when to transplant.

Transplant Timing: Don't rush the hardening-off process in Step 2! Gradually increase outdoor exposure by 30 minutes daily after the initial 1-2 hours. I've seen seedlings shocked by sudden temperature changes, so take your time. Also, transplant on a cloudy day or in the late afternoon to reduce stress on young plants.

Soil Preparation: Before planting, mix 2-3 inches of compost into your hills—this gives those heavy-feeding squash an immediate nutrient boost. I like to add a handful of crushed eggshells for calcium, which prevents blossom-end rot. And here's a trick: water the hills thoroughly the day before transplanting to help roots establish faster.

Harvest Strategy: Those 6-8 inch squash grow fast, so set a reminder to check plants every 2-3 days—I've lost perfect squash to overgrowth in just 48 hours! Use a sharp knife to harvest, and always leave that 1 inch stem attached. This small detail prevents rot and extends storage life by up to 5 days.

Frequently asked questions

What’s the best time to plant Long Island Cheese Squash?

Plant seeds after the last frost when soil temperatures reach at least 60°F (15°C). For a head start, sow indoors 2–3 weeks before transplanting. This variety thrives in warm weather, so avoid early spring planting—it won’t germinate well in cold soil.
