Whether you're growing butternut, acorn, or any other type, knowing when and how to harvest your squash can make a significant difference in taste and longevity.
Quick Answer
Harvest squash when the skin is hard enough that you can't pierce it with your fingernail, and the stem has turned brown and dry. This typically occurs in late summer to early autumn in the UK.
Understanding Squash Varieties
There are two main categories of squash: summer and winter. Summer squash, like courgettes, are harvested while still immature. Winter squash, such as butternut and acorn, are left to mature fully on the vine.
Summer vs Winter Squash
| Type | Harvest Time | Characteristics |
|---|---|---|
| Summer Squash | Mid to Late Summer | Soft skin, tender flesh |
| Winter Squash | Late Summer to Autumn | Hard skin, stores well |
When to Harvest Squash
The timing for harvesting squash depends largely on the variety. For winter squash, you want them to reach full maturity. In the Midlands, this often means waiting until late September or even October.
- Check the skin hardness; it should resist being punctured by a fingernail.
- Look for dry, brown stems as an indicator of maturity.
- Harvest before the first frost to avoid damage.
Signs of Ready-to-Harvest Squash
For both summer and winter squash, the colour of the skin is a good indicator. It should be rich and full with no green patches (unless the variety has green skin). The weight is another clue; they should feel heavy for their size.
How to Harvest Squash
When it comes to actually harvesting your squash, a few techniques can ensure the best results. Use a sharp knife or pruners to cut the stem, leaving a couple of inches attached to the squash. This helps prevent rot.
- Avoid twisting the squash off the vine, as this can damage the plant.
- Handle squash gently to avoid bruising the skin.
- Store winter squash in a cool, dry place to extend shelf life.
Post-Harvest Care
Once harvested, winter squash can benefit from a curing period. This involves leaving them in a warm, dry place for about 10 days. Curing helps harden the skin further, improving storage potential.
Storage Tips
Store your winter squash in a single layer, ideally in a garage or shed where temperatures remain steady. Avoid stacking to prevent pressure points that could lead to spoilage.
Frequently Asked Questions
How can I tell if my squash is overripe?
Overripe squash will often have softer spots and may start to lose their vibrant colour. They also might feel lighter than they should, indicating moisture loss.
Can I harvest squash early?
Yes, but it depends on the type. Summer squash can be picked early, but winter squash should be allowed to mature fully for best taste and storage.
What should I do with damaged squash?
Use damaged squash as soon as possible, as they won't store well. If the damage is minor, cut away the affected area and cook the rest.
