When Are Butternut Squash Ready To Be Picked

Butternut squash are ready to be picked when they’ve reached full maturity, which typically means about 90 to 110 days after planting.
 
You’ll know your butternut squash are ready to be picked when the skin has turned a uniform, deep tan or beige color with no green streaks remaining.
 
But timing isn’t the only clue, so let’s dig into the visual, tactile, and stem-based signs that tell you exactly when butternut squash are ready for harvest.
 
In this post, we’ll explore how to tell when butternut squash are ready to be picked, what happens if you pick them too early, and the best ways to cure and store them after harvest.
 
Let’s get into it so you can enjoy that sweet, nutty flavor at its absolute peak.
 

How to Know When Butternut Squash Are Ready to Be Picked

Knowing when butternut squash are ready to be picked isn’t complicated once you know what to look for.
 
Here are the most reliable indicators that your squash have reached that perfect harvest window.
 

1. Check the Skin Color for a Uniform Tan

The very first sign that butternut squash are ready to be picked is the skin color.
 
A mature butternut squash has a smooth, hard skin that’s a consistent, pale tan or light beige all over.
 
If you still see any green patches or faint stripes, your butternut squash are not ready to be picked yet.
 
Give them more time on the vine because those green areas indicate the flesh underneath hasn’t fully ripened or sweetened.
 
The color change from green to tan is your squash telling you it’s storing up those natural sugars that make it taste so wonderful.
 

2. Test the Hardness of the Rind

Another excellent way to determine when butternut squash are ready to be picked is by pressing your thumbnail against the skin.
 
If the rind is so hard that your thumbnail can’t easily pierce it, then your butternut squash are ready to be picked without question.
 
An immature squash will have a tender rind that scratches or dents with just light pressure.
 
That softness means the squash is still actively growing and absorbing water, so it hasn’t developed that dense, sweet flesh yet.
 
You want that crisp, unyielding shell because it protects the squash during storage and signals complete maturity.
 

3. Look at the Stem for Signs of Readiness

The stem is another fantastic clue for when butternut squash are ready to be picked.
 
As the squash matures, the stem will begin to dry out and turn from a supple green to a woody, brownish-gray color.
 
Also, check where the stem attaches to the vine itself.
 
That attachment point often starts to crack or separate slightly when butternut squash are ready to be picked.
 
If the stem still looks green and moist, the squash is still receiving nutrients from the plant, so hold off on harvesting.
 
Pro tip: Always leave a few inches of stem attached when you cut the squash.
 
That stem stub helps prevent rot from entering the squash during storage.
 

4. Tap the Squash and Listen for a Hollow Sound

Listening to your butternut squash can also clue you in on when they’re ready to be picked.
 
Give the squash a gentle tap with your knuckles.
 
If you hear a deep, hollow sound, that means the flesh is dense and fully mature.
 
A dull, thudding sound usually indicates the squash still has too much water content and isn’t quite ripe.
 
While this method takes a bit of practice, it’s a fun and effective way to confirm whether butternut squash are ready to be picked alongside the other signs.
 

5. Count the Days Since Planting

Finally, mark your calendar because days to maturity are a key indicator of when butternut squash are ready to be picked.
 
Most butternut squash varieties need about 90 to 110 days from the moment you plant the seeds.
 
However, this number can shift based on your local climate, summer temperatures, and soil quality.
 
If you’re approaching that 90-day mark, start checking the color and hardiness more frequently.
 
But don’t rely solely on the calendar because weather variations can speed up or delay ripening by a couple of weeks.
 

What Happens If You Pick Butternut Squash Too Early

We all get a little eager sometimes, but it’s helpful to know what happens if you pick butternut squash before they’re ready.
 
Unlike tomatoes or peaches, butternut squash will not continue to ripen or sweeten after they’ve been removed from the vine.
 
So, when butternut squash are picked too early, they’ll have pale, watery flesh that lacks that rich, nutty flavor you’re craving.
 
The squash will also store poorly and tend to rot quickly because its skin hasn’t hardened into that protective layer.
 
That said, if you accidentally pick an immature one, don’t toss it.
 
You can still use it in soups or dishes where you’ll be cooking it down with other bold flavors, since the texture will be softer and less sweet.
 
But for the best eating experience and longest shelf life, patience really is key when deciding when butternut squash are ready to be picked.
 

The Best Time of Day and Weather for Harvesting

The timing of your harvest day also matters when figuring out when butternut squash are ready to be picked.
 
Aim to pick your squash on a dry, sunny day, preferably in the late morning after the dew has evaporated.
 
Harvesting when the squash and vines are dry minimizes the risk of introducing mold or bacteria through any small cuts you might make.
 
Also, if a heavy frost is forecast, that’s a strong signal that butternut squash are ready to be picked immediately, even if they haven’t fully colored up yet.
 
A light frost can damage the squash and ruin their storage potential, so always prioritize picking before that first hard freeze hits your garden.
 

How to Cure and Store Your Picked Butternut Squash

Once you’ve confirmed that your butternut squash are ready to be picked, the work doesn’t end there.
 
Curing is a crucial step that helps the skin harden fully and extends the shelf life for months.
 
To cure them, keep your harvested squash in a warm, dry, well-ventilated spot for about 10 to 14 days.
 
Aim for temperatures around 70 to 80°F (21 to 27°C) with good air circulation so the skin can toughen up properly.
 
After curing, move the butternut squash to a cool, dark, and dry place, like a pantry or basement, where temperatures stay between 50 and 55°F (10 and 13°C).
 
Properly cured and stored butternut squash can easily last for two to three months or even longer.
 
Just check them occasionally and remove any that show signs of soft spots or mold so they don’t spoil your whole harvest.
 

So, When Are Butternut Squash Ready to Be Picked?

Butternut squash are ready to be picked when their skin is a uniform tan color, the rind is too hard for a thumbnail to pierce, and the stem has dried to a woody brown.
 
You can also trust the hollow sound when tapped and confirm you’re at that 90-to-110-day mark from planting.
 
If any of those signs are missing, your butternut squash are not ready to be picked yet, so give them more time on the vine.
 
Remember that butternut squash will not ripen off the vine, so waiting for that perfect moment is essential for the best flavor.
 
Once you’ve verified that your butternut squash are ready to be picked, harvest on a dry day, cure them properly, and store them somewhere cool and dark.
 
Do that, and you’ll be enjoying sweet, creamy butternut squash soups, roasts, and purees all winter long.
 
Happy harvesting and enjoy every delicious bite of your perfectly timed squash.
