Many winter squash fruits can appear to be mature before they are actually ready to harvest, and some require time in storage after harvest for best eating quality. For the best-quality squash, wait to harvest all types until they are mature — at least 50–55 days after the fruit has set — and cure before storing and eating.
Curing Winter Squash
After cutting the fruits from the vine, sun-cure in the field for 5–7 days, or, cure indoors for 5–7 days at 80–85°F (27–29°C), in an area with good air ventilation.
As noted above, a good rule of thumb is to consume small-fruited types first. Read on for more tips on specific winter squash types.

Spaghetti squash, too, can be consumed right away after harvest, and will store only about 2½ months.
The fruits of these types, like acorn squash, often have a dark-orange "ground spot" when mature. Fruits can be consumed at harvest, and eating quality is best within 3 months of harvest.
Varieties such as 'Sunshine,' ,'Red Kuri,' and Shokichi types can be consumed at harvest, and will store up to 4 months. Dry, corky stems are a good indication of fruit maturity.
Fruits are best after 1–1½ months of storage, but will also store 4–6 months. Dry, corky stems are a good indication of fruit maturity.
Fruits are best after 1–2 months of storage, and will keep 4–6 months. (NOTE: Because of its smaller size, 'Butterscotch PMR' is an exception; it can be consumed at harvest, and is best within 3 months of harvest.)
