Carnival squash is just one variety of over 100 categorized types of these cucurbits. One of the most colorful squash varieties, the ‘field pumpkin’ (Cucurbita pepo) is a relative of pumpkins and gourds. Carnival acorn squash is a winter squash variety with a hard rind and pleasant flesh. Can you eat carnival squash? Yes, absolutely – and these plump beauties are amongst the most delicious common types of squash you can eat. Carnival squash is most often roasted, where the flesh becomes tender, and it’s a perfect side dish for meats and other main dishes.
Key areas of attention for cultivating successful carnival squash, as when growing other squash varieties, are space and support. Factor in ample growing room around individual cucurbit plants (a couple of feet works best), and ideally incorporate some form of climbing support for plants in the form of a trellis or a framework of stakes. When growing carnival squash, you then need to focus on the following for plants that thrive and crops that are as healthy, bountiful and robust as possible.

Light:
As you will find when growing winter squash, carnivals need at least six hours of full sun daily. A lighting range of eight-ten hours per day will result in more blossoms and therefore fruits. Plant seeds in a sunny location of the garden in prepared soil.

Watering:
Seeds and seedlings should be kept moist but not soggy. As the plant matures, it is best to water deeply but infrequently. This allows the plant to develop deep roots and makes them more drought-tolerant. Water when the top few inches (8cm) feel dry to the touch. As with butternut squash, water once or twice a week with two inches (5cm) of water. The best time to water is early morning. This reduces evaporation and allows the plant to uptake moisture. It will also cut down on fungal disease by allowing the leaves to dry quickly.

Temperature & Humidity:
The seed may be planted in soil that has warmed to 65°F (18°C) but a temperature of 70°F (21°C) will result in quicker germination. During the growing period, the ideal temperature range is 50-60°F (10-15.5°C) with a 50 percent humidity. Squash plants can tolerate a light frost for a few hours, but if temperatures drop below freezing they will need a blanket or frost-free fabric for protection.

Soil and Compost:
Fertile, loose, well-draining soil is a must. Sand, loam and light clay are all fine. A soil pH of 6-6.8 is perfect. Incorporate compost, leaf litter or other organic soil amendments prior to planting to loosen soil, help hold moisture, and enhance the nutrient level of the soil.

Fertilizer Needs:
Squash are heavy feeders and need plenty of nutrients to produce the heaithiest, sweetest squash fruits. Incorporate compost to the soil prior to planting or mix in a fertilizer with a ratio of 5-10-10. You can side dress with well-rotted manure, add compost to top the hills, or use compost tea every two-three weeks. If using a synthetic fertilizer, use a balanced ratio. After fertilizing, water the material in well to help release the nutrients and prevent foliage burn.
