Summer squash like zucchini and yellow crookneck are picked immature, while winter squash like butternut and acorn are picked fully mature.
 
The simplest way to know when to pick a squash is to check the skin’s firmness and the stem’s condition, as these are consistent across all varieties.
 

1. Summer Squash: Pick Them Young and Tender

For summer squash, you know when to pick a squash when it’s about six to eight inches long for zucchini, or four to six inches for pattypan types.
 
You know when to pick a squash of this type because the skin will still be glossy and soft enough to pierce with a fingernail.
 
If you wait too long, the seeds get tough and the flesh becomes watery and bitter.
 
Check your plants every couple of days, because summer squash grow shockingly fast and can go from perfect to overgrown in just three to four days.
 
Grab the fruit and give it a gentle twist, and if it comes off with little effort, that’s another sign you know when to pick a squash.
 

2. Winter Squash: Wait for Full Maturity

With winter squash, you know when to pick a squash only after the vines have started to die back and the rind has hardened.
 
You know when to pick a squash of this type when you can’t easily dent the skin with a fingernail, as that signals a fully cured rind.
 
The color should be uniform and deep, with no green patches, and the stem should look dry and corky rather than green and moist.
 
Another clue to know when to pick a squash for winter types is the sound test, so give it a thump and listen for a hollow sound.
 
That hollow ring means the flesh inside has thickened and the sugars have developed, so you know when to pick a squash for the best storage life.
 
If frost is predicted, though, harvest immediately even if not fully mature, because frost damages the fruit’s quality.
