Kabocha
Winter Sweet Kabocha Squash is an F1 hybrid that delivers unparalleled eating quality with exceptional storage longevity, a rare combination that makes it a standout choice for gardeners who want both flavor and season-long harvests. This bush-type squash reaches maturity in 95 days from seed, producing the dense, sweet flesh kabochas are prized for, but with the added bonus of keeping up to six months in proper storage conditions. The compact growth habit means you can tuck it into smaller garden spaces without sacrificing yield, and the reliable hybrid vigor ensures consistent, productive plants even in variable growing seasons.

What sets Winter Sweet apart is the marriage of exceptional flavor with truly impressive storage life. Unlike many kabocha varieties that peak fresh from the field, Winter Sweet actually gets sweeter over a few weeks of storage, deepening its already rich taste. The six-month storage window lets you enjoy peak-season harvests well into winter, and the bush growth habit means you're not wrestling with sprawling vines across your entire garden bed.
Winter Sweet Kabocha is grown for its dense, sweet flesh, which is ideal for roasting, pureeing into soups, or using in baking where you need a reliable, flavorful squash base. The flesh's natural sweetness and creamy texture when cooked make it perfect for both savory and slightly sweet preparations, from simple roasted wedges to more elaborate gratins and filled dishes.
Sow 2–3 seeds per 2-inch container or plug flat about 3 weeks before your intended transplant date. Once seedlings emerge, thin to one plant per container using scissors to minimize root disturbance. Harden plants for 4–7 days before moving them outdoors, gradually exposing them to outdoor conditions to avoid transplant shock.
After all danger of frost has passed and soil has warmed, transplant hardened seedlings outdoors at 6-inch spacing. Handle seedlings with care and minimize root disturbance during the transplanting process, as squash plants are sensitive to rough handling.
Harvest Winter Sweet after approximately 95 days when the skin has hardened and turned its mature color. Squashes are ready when they feel solid to pressure and cannot be easily pierced with a thumbnail. Cut the fruit from the vine using a sharp knife, leaving a short stem attached to improve storage life and reduce moisture loss.
