You can tell if butternut squash is ready to harvest when the skin turns a deep, solid tan and the vine starts to dry out.
If you’ve been wondering how to tell if butternut squash is ready to harvest, the good news is that this winter squash gives you plenty of visual and tactile clues.
Unlike summer squash, which you pick while tender, butternut squash is ready to harvest when it’s fully mature and the rind has hardened.
When you know how to tell if butternut squash is ready to harvest, you’ll get squash that stores for months and tastes sweeter.
In this post, we’ll walk through the signs that tell you when butternut squash is ready to harvest, plus a few tips to make sure you pick it at the perfect time.
Let’s get into it.
How to Tell If Butternut Squash Is Ready to Harvest
Knowing how to tell if butternut squash is ready to harvest comes down to a few key signals.
Here’s what to look for.
1. The Skin Turns Deep Tan
The most obvious sign that butternut squash is ready to harvest is the color change.
When butternut squash is ripe, its skin shifts from pale green to a rich, deep tan or beige.
If you can still see green stripes or patches, that butternut squash isn’t ready to harvest yet.
Wait until the color is uniform all the way around before you pick it.
2. The Rind Is Hard and Can’t Be Pierced
Another reliable way to tell if butternut squash is ready to harvest is by testing the rind.
Press your fingernail into the skin.
If it leaves a dent, the butternut squash isn’t ready to harvest.
If your nail can’t puncture the skin, that butternut squash is ready to harvest and fully mature.
This hardness is what allows butternut squash to store well for months.
3. The Vine Dries Out and Turns Brown
The vine gives you a clear hint about when butternut squash is ready to harvest.
As the squash matures, the vine starts to wither and turn brown.
When the vine is dry and woody, that’s a strong signal that butternut squash is ready to harvest.
Don’t rush it, though.
If the vine is still green, the butternut squash is still growing and isn’t ready to harvest.
4. The Stem Turns Brown and Corky
The stem is another clue for how to tell if butternut squash is ready to harvest.
A ripe butternut squash has a stem that’s dry, brown, and slightly corky.
If the stem is still green and flexible, the butternut squash isn’t ready to harvest.
Leave it on the vine a bit longer.
5. The Squash Feels Heavy for Its Size
A butternut squash that’s ready to harvest feels surprisingly heavy.
Pick it up and compare it to its size.
If it feels dense and solid, that butternut squash is ready to harvest.
If it feels light, it may have been harvested too early or stored too long.
When Butternut Squash Is Ready to Harvest by Season
Timing matters just as much as the visual signs.
Butternut squash is usually ready to harvest in late summer to early fall, roughly 100 to 120 days after planting.
If you planted in late spring, expect butternut squash to be ready to harvest sometime between September and October.
In warmer climates, butternut squash may be ready to harvest a little earlier.
In cooler zones, it might take until the first light frost.
A light frost won’t hurt butternut squash, but a hard freeze will.
So if a hard freeze is coming, harvest your butternut squash right away even if it’s not fully ripe.
How to Harvest Butternut Squash the Right Way
Once you know how to tell if butternut squash is ready to harvest, the actual picking is easy.
Use a sharp knife or pruners to cut the stem, leaving about two inches attached.
Don’t yank or twist the butternut squash off the vine, as that can damage the stem and shorten storage life.
After harvesting, let the butternut squash cure in a warm, sunny spot for about a week.
This hardens the skin further and helps the butternut squash store longer.
Then move it to a cool, dry place, and your butternut squash will keep for several months.
So, How Do You Tell If Butternut Squash Is Ready to Harvest?
You can tell if butternut squash is ready to harvest when the skin is deep tan, the rind is hard, and the vine has dried out.
