Many winter squash varieties need a curing period after harvesting; while acorn 
squash can be eaten immediately after being picked up from storage, their flavor
becomes richer with time.

Harvesting acorn squash should occur between September and October in temperate 
climates. You can determine when an acorn squash is ready by inspecting its skin
texture, color and stem.

## The Color

Acorn squash’s color can tell a lot about when it’s ready to be harvested, as this
forest green variety often develops a deep orange spot near its base when mature–
this serves as an indicator of ripeness because winter squash prefers having tough
skins so that it keeps for an extended period unlike its summer cousin.

As it matures, an acorn squash will develop a hard outer shell. A good way to test
this is by puncturing its rind with your fingernail; if this proves challenging 
then your harvest could be imminent!

Harvest acorn squash when they are still green and flexible for optimal storage,
rather than when their skin turns yellow or orange – this will extend their shelf
life and help ensure longer storage time for this winter squash variety.

Use a sharp knife or garden pruning shears to cut the stem of an acorn squash, leaving
an inch attached to its main body of fruit. This will help retain moisture and protect
it from prematurely decaying. Store them in a dry area between 50-55 degrees Fahrenheit;
apples, pears or tomatoes could release ethylene gas which will shorten its shelf
life.

## The Rind

Ripe acorn squash skin typically displays a duller sheen than unripe fruit, while
remaining flexible and not rigid. A simple way to determine when your squash is 
ready for harvest is pressing its skin with your thumb; if it yields, allow additional
time for maturation.

When harvesting, use garden pruning shears or loppers with clean blades to cut acorn
squash from its stem rather than ripping it off, to avoid damaging or prematurely
rotting it. Ripe acorn squash should be stored in cool and dry environments such
as basements or garages for storage; they’ll last several months at this temperature
if stored single layer in this manner and regularly monitored for signs of spoilage
or any that show early signs of spoiling before discarding any that show any sign
of spoilage before discarding them altogether.

Acorn squash is a warm-season annual, and its harvest depends on which variety is
chosen. On average, an acorn matures within 80-100 days – to narrow down harvest
window look for “days to maturity” information on seed packets. Winter varieties
like kabocha and hubbard squash require curing post harvest but have longer storage
lives compared with acorn varieties; their ground spot turns dark-orange as an indicator
that they’re ready to store away for future use.

## The Stem

Acorn squash plants typically take 80-100 days from seed to maturity and it’s important
to wait until they’re fully ripe before cutting them from their vine. Gardening 
expert Rebecca Sears from Ferry-Morse advises against cutting squash before the 
fruits have reached harvest stage, which she considers an easily avoidable mistake.

She suggests looking at the color, rind and stem to determine when it is time to
harvest an acorn squash. Ripe ones typically feature dark green hues with orange-
tinged spots near where it touches the ground; additionally, the stem connecting
the squash should also appear dry and withered.

Ripe acorn squash will have a dull finish with solid resistance when gently pressed
by your thumb. The skin should be tough yet smooth while its flesh will likely be
heavier than normal.

Allowing winter squashes to fully mature before harvest is key, as they need time
to build tough skins before being harvested for longer storage life than summer 
varieties with thinner skins.

This year’s crop of acorn squash can be used in numerous recipes from soups to side
dishes and desserts. To achieve optimal results, this popular winter squash variety
should be grown in well-draining yet moderately fertile soil with ample drainage;
plant seeds outdoors after frost risk has passed in spring with 3-4 feet spacing
between seeds.

## The Weight

If you’re harvesting Acorn squash for cooking, one indicator of ripeness is weight.
When pressed with your thumb, the squash should feel heavy for its size and offer
solid resistance when pressed against. Furthermore, its firm texture should lack
soft spots or ridges. An easier way to determine its readiness is making sounds 
with its rind – gently tapping with your knuckles against it should produce a hollow
wooden sound as an indication that its skin has toughened.

Acorn squash nutrition includes an abundance of beta-carotene, an antioxidant with
powerful cancer-fighting capabilities. Furthermore, this nutritious fruit also serves
as an excellent source of vitamin A which promotes eye and skin health while supporting
immune system health.

As with other winter squash varieties, acorn squashes should be harvested when they
reach full maturity and have hardened rinds – typically during September or October
in temperate climates. They benefit from an ideal environment of warm days and cool
nights which increase sugar accumulation while simultaneously heightening nuttiness.
Try not to harvest them prematurely as this will impede storage potential; leave
them to mature on their vine until ready for harvest and be sure to do it before
frost arrives as this could damage its sweet nutty flavor as well as stringy texture!
