Butternut squash: the ultimate guide to frost resistance for bountiful harvests

Butternut squash is a hardy vegetable that can withstand some frost, but it is not as tolerant as other winter squashes like acorn or spaghetti squash. A light frost (temperatures between 29-32°F) will not harm butternut squash plants, but a hard frost (temperatures below 28°F) can damage or kill them.

How to Protect Butternut Squash from Frost

If you live in an area where frost is expected, there are a few things you can do to protect your butternut squash plants:

• Cover the plants with a blanket or tarp. This will help to insulate the plants and protect them from the cold.
• Water the plants deeply before a frost. This will help to keep the soil moist and prevent the plants from wilting.
• Mulch around the plants with straw or leaves. This will help to insulate the soil and keep the roots warm.
• Harvest the squash before a hard frost. If you know that a hard frost is coming, harvest the squash as soon as possible.
