How To Get A Green Pumpkin To Turn Orange

To get a green pumpkin to turn orange, you mainly need patience and the right conditions, because pumpkins change color as part of their natural ripening process.
 
When a pumpkin is green, it simply hasn’t finished maturing yet, and over time, it will develop that classic orange hue you’re looking for.
 
Whether it’s still on the vine or you’ve already picked it, there are several ways to help a green pumpkin turn orange, and knowing how the process works makes it much easier to get the results you want.
 
In this post, we’ll look at why green pumpkins turn orange, how to speed up the color change, and what you can do to make sure your pumpkin ripens properly.
 
Let’s dive in.
 

Why a Green Pumpkin Turns Orange

A green pumpkin turns orange because of the natural ripening process that happens as the fruit matures.
 
Here’s what’s going on beneath that green skin:
 

1. Chlorophyll Breaks Down Over Time

The green color in a pumpkin comes from chlorophyll, the same pigment that makes leaves green.
 
As the pumpkin ripens, chlorophyll starts to break down and fade away.
 
This is why a green pumpkin eventually loses that green tint and starts showing the colors hiding underneath.
 
It’s a totally natural process, and it happens whether the pumpkin is still connected to the vine or sitting on your porch.
 

2. Carotenoids Take Over

Once chlorophyll fades, carotenoids step in and become the dominant pigment.
 
Carotenoids are responsible for the orange, yellow, and red colors you see in pumpkins, carrots, and tomatoes.
 
As the pumpkin matures, these pigments build up and give the skin that deep orange color.
 
So getting a green pumpkin to turn orange is really just about letting the carotenoids do their job.
 

3. Ethylene Gas Speeds Things Up

Pumpkins naturally release ethylene gas, which is a plant hormone that drives ripening.
 
The more ethylene that builds up around the pumpkin, the faster it will turn orange.
 
This is why a green pumpkin often ripens faster when it’s near other ripe fruits, like apples or bananas.
 
You can use this to your advantage if you want your green pumpkin to turn orange a little quicker.
 

How to Get a Green Pumpkin to Turn Orange on the Vine

If your green pumpkin is still on the vine, the easiest way to get it to turn orange is to leave it alone and let nature do its thing.
 
But there are a few things you can do to help it along:
 

1. Give It More Time

The simplest answer to how to get a green pumpkin to turn orange is just to wait.
 
Most pumpkins need somewhere between 90 and 120 days to fully mature, depending on the variety.
 
If yours is still green, it may simply need another week or two on the vine.
 
Keep an eye on it and check for color changes every few days.
 

2. Reduce Watering

Cutting back on watering as the pumpkin nears maturity can encourage ripening.
 
Too much water late in the season can keep the pumpkin green and delay the color change.
 
Ease off the watering and let the soil dry out a bit between sessions.
 
This signals to the plant that it’s time to finish maturing the fruit.
 

3. Make Sure It Gets Plenty of Sunlight

Sunlight helps pumpkins ripen and develop their color.
 
If your green pumpkin is shaded by leaves or other pumpkins, it may take longer to turn orange.
 
Gently move leaves aside or rotate the pumpkin so it gets more sun exposure.
 
Just be careful not to break the stem, since that can stop the ripening process entirely.
 

4. Protect It from Frost

Cold weather can damage a green pumpkin and stop it from turning orange.
 
If frost is in the forecast, cover your pumpkin with a blanket or bring it indoors if possible.
 
Once a pumpkin is damaged by frost, it won’t ripen properly and may start to rot.
 

How to Turn a Green Pumpkin Orange After Picking

If you’ve already picked your green pumpkin, don’t worry.
 
You can still get a green pumpkin to turn orange off the vine as long as it was mature enough when you picked it.
 
Here’s how:
 

1. Keep It in a Warm, Dry Spot

Place your green pumpkin in a warm, dry area with good air circulation.
 
Temperatures around 70 to 80°F are ideal for ripening.
 
Avoid damp, cold spaces like basements, since those conditions can cause mold and slow down the color change.
 

2. Use a Paper Bag to Trap Ethylene

If you want to speed things up, put your green pumpkin in a paper bag.
 
The bag traps the ethylene gas the pumpkin releases, which helps it turn orange faster.
 
You can also add a ripe apple or banana to the bag for an extra boost of ethylene.
 
Check on it every day so it doesn’t get too soft or start to rot.
 

3. Turn It Regularly

Rotate your pumpkin every few days so all sides get equal exposure to air and light.
 
This helps the color develop evenly and prevents flat, soft spots from forming.
 
It also gives you a chance to spot any signs of rot early.
 

4. Be Patient

Getting a green pumpkin to turn orange off the vine can take one to two weeks, sometimes longer.
 
If the pumpkin was picked too early, it may never fully turn orange, but it will still ripen enough to use for cooking or decorating.
 
Give it time and check it daily.
 

So, How Do You Get a Green Pumpkin to Turn Orange?

To get a green pumpkin to turn orange, you need to let the natural ripening process run its course, whether that’s on the vine or off it.
 
Chlorophyll needs to break down, carotenoids need to build up, and ethylene gas helps move things along.
 
With warmth, patience, and a little attention, your green pumpkin will turn orange and be ready for carving or cooking.
