How long can acorn squash stay on the vine before harvest?
Acorn squash can typically remain on the vine for about 70 to 90 days after planting. However, once the squash reaches maturity, they can stay on the vine for an additional 2 to 4 weeks. The determination of when to harvest depends on several factors, including the squash’s size, color, and the overall health of the plant.
It’s crucial to monitor the squash as it approaches maturity. The skin should be hard, and the color should change to a deep green or orange hue, depending on the variety. If the skin is too soft, the squash may not be ready for harvesting, and leaving them on the vine past maturity can lead to deterioration or pest issues.
What are the signs that acorn squash is ready to be harvested?
When acorn squash is ready for harvest, several indicators will be evident. The most noticeable sign is the hardening of the skin, which should be nearly impenetrable to your fingernail. Additionally, the color of the squash will shift toward its mature hue, typically a deep green or orange, depending on the variety.
Another sign of readiness is the presence of a dry stem. Once the stem turns brown and begins to wither, it indicates that the squash is mature. It’s also important to check for blemishes or soft spots, which can suggest the squash is overripe and starting to decay.
Can acorn squash ripen after being harvested from the vine?
Yes, acorn squash can continue to ripen after being harvested, although they should ideally be picked when they are fully mature.
