Spaghetti squash is a member of the Cucurbitaceae family, which includes pumpkins, cucumbers, and melons. It's an oblong, yellow fruit that can range in size from 2 to 5 pounds. When cooked, its flesh separates into strands that look remarkably like spaghetti, hence the name.
I remember the first time I cooked spaghetti squash. I had heard a lot about it but was skeptical about whether it would really resemble spaghetti. One evening, with a little trepidation, I decided to give it a try. As I scraped the flesh with a fork, it transformed into perfect spaghetti-like strands right before my eyes. The real magic happened when I tasted it—it was delicious, light, and paired wonderfully with my homemade marinara sauce. Since that day, spaghetti squash has become a staple in my kitchen, a go-to for a healthy and satisfying meal.
In this article, we will explore everything you need to know about spaghetti squash—from its characteristics to planting, growing, and harvesting, as well as how to store it and handle common pests and diseases.
Characteristics of Spaghetti Squash

Size: Spaghetti squash fruits typically range from 8 to 12 inches in length and 4 to 6 inches in diameter. These dimensions allow the squash to produce a substantial amount of flesh inside, making them ideal for use in various recipes that require a vegetable substitute for pasta.
Plant Type: Spaghetti squash grows on a sprawling vine that can extend up to 20 feet in length. This vining nature requires ample space in the garden or a trellis system for support. The vines produce large, lobed leaves and yellow flowers, which eventually develop into the squash fruits.
Days to Harvest: From planting to harvest, spaghetti squash requires approximately 90 to 110 days. This period includes the time needed for the seeds to germinate, the vines to grow and spread, and the fruits to mature fully. The specific number of days can vary based on growing conditions such as climate, soil quality, and care practices.
Flesh: The flesh of spaghetti squash is pale yellow and transforms into spaghetti-like strands when cooked. This unique characteristic makes it a popular low-carb alternative to traditional pasta. When baked, boiled, or microwaved, the flesh softens and can be easily separated into long, thin strands using a fork.
Skin: The skin of mature spaghetti squash is hard and yellow, with a tough outer shell that effectively protects the flesh inside. This durability makes the squash suitable for storage over several months, provided it is kept in a cool, dry place. The tough skin needs to be cut or pierced before cooking to allow steam to escape and ensure even cooking.
Planting Spaghetti Squash
Planting spaghetti squash can be a rewarding endeavor, especially if you enjoy its unique texture and flavor. Here’s a detailed guide to help you successfully plant and grow spaghetti squash:
When to Plant
Spaghetti squash should be planted in late spring to early summer, once all danger of frost has passed and the soil has warmed to at least 70°F (21°C). This temperature ensures that the seeds will germinate successfully and the young plants will thrive. In most regions, this optimal planting time means sowing seeds outdoors in late May to early June. For gardeners in warmer climates, planting may occur a bit earlier, while those in cooler regions might need to wait until early June. It’s crucial to monitor local weather patterns and soil temperatures to determine the best planting time.
How to Plant
Choose a Site:
Select a sunny location that receives at least 6 to 8 hours of direct sunlight per day. Spaghetti squash vines are vigorous growers and need plenty of space to spread out, so ensure there is ample room for them to grow. The site should have well-drained soil to prevent waterlogging, which can lead to root rot.
Soil Preparation:

Prepare the soil by enriching it with organic matter such as compost or well-rotted manure. This improves soil structure, fertility, and moisture retention. Spaghetti squash prefers slightly acidic to neutral soil, with a pH range of 6.0 to 6.8. Conduct a soil test to determine the pH level and amend the soil accordingly if needed.
Planting Seeds:

After the last frost date and once the soil has warmed, plant the seeds directly in the ground. Create small mounds or "hills" of soil, spacing them 4-6 feet apart to allow for the extensive growth of the vines. Sow 2-3 seeds per hill, planting them about 1 inch deep. The hills will provide good drainage and encourage strong root development.
Thinning:
Once the seedlings have developed two sets of true leaves, it's time to thin them. True leaves are the second set of leaves that appear and are different from the initial seed leaves (cotyledons). Choose the strongest, healthiest seedling in each hill and remove the others by cutting them at the soil line. This thinning process reduces competition for nutrients and water, allowing the remaining seedling to grow more vigorously.
Growing Spaghetti Squash
Growing spaghetti squash can provide you with a delicious and nutritious vegetable to enjoy. Here’s a comprehensive guide to help you successfully grow spaghetti squash:
Germination

Seeds should germinate within 7-10 days if conditions are optimal. During this period, maintain a consistently moist soil environment to facilitate sprouting. Avoid waterlogging, as overly wet soil can lead to seed rot. A gentle misting or light watering can help achieve the right moisture level.
Seedling Care
As the seedlings emerge and start to grow, it's important to continue regular watering to support their development. Apply mulch around the young plants to help retain soil moisture and reduce weed growth, which can compete with seedlings for nutrients and water. Organic mulch, such as straw or wood chips, works well for this purpose.
Supporting Vines

Spaghetti squash vines are quite vigorous and can be allowed to sprawl on the ground. However, using a trellis, cage, or other support structures can save garden space and improve air circulation around the plants. This setup helps prevent diseases and makes it easier to manage and harvest the squash. Secure the vines gently to the supports to avoid damage.
Watering

Water your spaghetti squash plants deeply and regularly, ensuring they receive about 1-2 inches of water per week. Deep watering encourages the roots to grow deeper into the soil, providing better support for the plant. Always water at the base of the plants to keep the foliage dry, which helps prevent fungal diseases. Early morning watering is ideal to allow any moisture on the leaves to dry quickly.
Fertilizing
Once the plants are established, begin a regular fertilizing routine with a balanced fertilizer, such as 10-10-10 (nitrogen-phosphorus-potassium). Apply the fertilizer every 3-4 weeks throughout the growing season. Be careful not to over-fertilize, as this can lead to excessive foliage growth at the expense of fruit development. Follow the manufacturer’s instructions for application rates.
Pruning
Pruning spaghetti squash plants is not strictly necessary but can be beneficial for managing plant size and directing energy towards fruit production. Remove any dead or diseased leaves promptly to maintain plant health. If the vines become overcrowded, thin them out by cutting back some of the excess growth. This helps improve air circulation and sunlight penetration, reducing the risk of disease and promoting better fruit development.
Storing Spaghetti Squash
Properly storing spaghetti squash can extend its shelf life and ensure you can enjoy it throughout the winter.
Curing
To effectively cure the squash, initiate the process by carefully harvesting mature specimens with intact stems. Ensure they are free from any damage or blemishes. Place the squash in a single layer, allowing ample space for air circulation, in a warm environment with temperatures ranging between 70-80°F (21-27°C). Optimal humidity levels should be maintained, ideally around 70-80%, to facilitate proper skin hardening without promoting mold growth.
During the curing period of 1-2 weeks, periodically inspect the squash for signs of decay or soft spots, promptly removing any affected specimens to prevent the spread of spoilage. As the curing progresses, you'll notice the skin developing a tougher texture, which is indicative of successful curing and readiness for storage.
Storage Conditions
Once the curing process is complete, transfer the cured squash to an appropriate storage location. Choose a cool and consistently cool environment, ideally within the recommended range of 50-55°F (10-13°C). It's essential to maintain low humidity levels, aiming for a relative humidity of 50-70%, to prevent moisture buildup that could lead to rot or mold formation.
Select a storage area that is well-ventilated and devoid of direct sunlight, as exposure to light can cause premature deterioration. Avoid storing squash near ethylene-producing fruits, such as apples or bananas, as ethylene can accelerate ripening and lead to premature spoilage.
Shelf Life
With vigilant adherence to proper storage conditions, spaghetti squash can maintain its quality for an extended period. When stored under optimal conditions, expect a shelf life ranging from 3 to 6 months. Periodically inspect stored squash for any signs of decay or softening, promptly removing any affected specimens to prevent the spread of spoilage and maximize the longevity of your squash harvest.
