When to Harvest Butternut Squash

Butternut squash is ready to harvest once fruits are fully developed and the skin becomes firm. Harvesting at the right time helps squash store well and maintain good flavour.

In the UK, butternut squash is usually harvested in autumn, often before the first frost.

Checking fruits regularly helps you harvest at the right stage.
