[Sunshine (F1) Squash Seed - Johnny's Selected Seeds
Fruits are typically ready about 50-55 days after fruit set, and should be harvested before any hard frosts. Cut fruits from vines and handle carefully. Sun cure by exposing fruits for 5-7 days or cure indoors by keeping squash at 80-85°F/27-29°C with good air ventilation.
Store at 50-60°F/10-15°C, 50-70% relative humidity and good ventilation. Repeated exposure to temperatures below 50°F/10°C may cause chilling damage. Kabochas get sweeter with a few weeks of storage. Green varieties will keep up to 4–5 months in storage; Winter Sweet will keep up to 6 months. Sunshine is the exception and is delicious right out of the field, but will only last a maximum of 3 months.
