Red Kuri earns its name from the Japanese word for chestnut, and tasting the golden, smooth flesh reveals why: the flavor is rich and intensely nutty, with an almost creamy texture that's drier than most winter squashes. This Japanese heirloom originated within cultivation traditions that emphasize deep respect for growing practices, and its striking teardrop form and luminous red-orange skin make it as ornamental as it is delicious. The fruits store beautifully through winter, and the plant thrives across a wide hardiness range, making it accessible to gardeners from cool northern regions into warmer zones.
Red Kuri shines in fall and winter cooking, where its dense, sweet, chestnut-like flesh becomes the star in roasted preparations, soups, and purees. The dry texture and rich flavor make it exceptional for baking into squash pies, mashing into side dishes, or simply halving and roasting until caramelized. Its natural sweetness requires no added sugar, and the smooth texture purées beautifully for creamy soups or autumnal desserts.

Start seeds indoors 3 to 4 weeks before your last frost date, planting them in warm soil between 70 and 85 degrees Fahrenheit. Sow seeds approximately 1 inch deep and keep soil consistently warm; seedlings typically emerge within 7 to 10 days.
Harden off seedlings gradually over 7 to 10 days before moving them outside after all frost danger has passed and soil has warmed. Space transplants 24 inches apart, with rows 36 inches apart, in a location receiving full sun.
Direct sow seeds outdoors after soil temperature reaches 70 degrees Fahrenheit and all frost risk has passed. Sow seeds 1 inch deep and thin seedlings to 24-inch spacing once they've developed their first true leaves.
Harvest Red Kuri fruits when the skin has fully deepened to a vibrant red-orange color and the stem begins to brown and harden, typically around 92 days from planting. The fruits should feel firm to pressure, and the skin should resist puncture from a fingernail. Cut fruits from the vine with 2 to 3 inches of stem attached, which helps them store longer and keeps the fruit intact. Harvest all fruits before the first hard frost, as this frost-tender variety stops developing once frost arrives.
