How To Make A Concrete Pumpkin

To make a concrete pumpkin, you’ll need a few simple materials and a little patience, but the result is a charming decoration that lasts for years.
 
Whether you’re crafting a concrete pumpkin for your porch or making a whole patch of them for a fall display, this project is easier than it looks.
 
In this post, we’ll walk through exactly how to make a concrete pumpkin step by step, from gathering supplies to finishing touches, so your DIY concrete pumpkin turns out perfectly.
 
Let’s get started.
 

How to Make a Concrete Pumpkin Step by Step

Making a concrete pumpkin is a straightforward process, and once you’ve done it, you’ll want to make more.
 
Here’s how to make a concrete pumpkin from start to finish:
 

1. Gather Your Materials

Before you make a concrete pumpkin, gather everything you need.
 
You’ll need a bag of concrete mix (a fast-setting mix works great for small concrete pumpkins), water, a mixing bucket, a trowel, and something to use as a mold.
 
For the mold, a plastic pumpkin bucket from the dollar store or a pumpkin-shaped silicone mold works beautifully.
 
You’ll also want a pumpkin stem (real or faux) for the top.
 

2. Prepare Your Mold

If you’re using a plastic bucket, coat the inside with a release agent like cooking spray so your concrete pumpkin pops out easily.
 
For a silicone mold, no release agent is needed.
 
Set your mold on a flat surface where it won’t be disturbed, since concrete pumpkin projects need to cure without being moved.
 

3. Mix the Concrete

Mix your concrete according to the package directions until it’s the consistency of thick peanut butter.
 
When making a concrete pumpkin, you want the mix smooth enough to fill the mold’s ridges but thick enough to hold its shape.
 
Scoop the concrete into your mold, filling it to the top.
 

4. Add the Stem

While the concrete is still wet, insert your stem into the top center of the concrete pumpkin.
 
This is the key step that makes a concrete pumpkin look like a real pumpkin.
 
You can use a real pumpkin stem, a twig, or a faux stem glued in later.
 

5. Tap Out Air Bubbles

Gently tap the sides of the mold to release trapped air bubbles so your DIY concrete pumpkin cures smooth.
 

6. Let It Cure and Unmold

Let your concrete pumpkin cure for 24 to 48 hours before removing it from the mold.
 
Once cured, pop it out, and you’ll have a solid, beautiful concrete pumpkin ready to paint or display.
 

Tips for Making a Concrete Pumpkin Look Real

A concrete pumpkin doesn’t have to look like, well, concrete.
 
Here are some tips for making a concrete pumpkin look more realistic:
 

1. Add Pumpkin Ridges

If your mold doesn’t have natural ridges, carve shallow vertical lines into the concrete while it’s still wet.
 
This gives your concrete pumpkin that classic pumpkin shape.
 

2. Paint and Stain

Once your concrete pumpkin is dry, paint it with orange acrylic paint or stains.
 
A concrete pumpkin painted with warm oranges and golds looks surprisingly realistic on a porch display.
 

3. Seal the Surface

Sealing your concrete pumpkin helps it resist moisture and weather.
 
If your concrete pumpkin will live outdoors, a weatherproof sealer is a must.
 

4. Pair It With Real Pumpkins

One of the best tricks for making a concrete pumpkin look natural is to mix it in with real pumpkins on your porch.
 
Your guests may not even be able to tell which is the homemade concrete pumpkin.
 

Common Mistakes to Avoid With DIY Concrete Pumpkins

Getting a great result with a concrete pumpkin comes down to avoiding a few common slip-ups.
 

1. Mixing Concrete Too Thin

If your concrete pumpkin mixture is too watery, the details of your mold will blur and the pumpkin might crack.
 
Always follow the ratio on the bag for a solid concrete pumpkin.
 

2. Demolding Too Soon

A concrete pumpkin needs full cure time.
 
Remove it early, and you risk breaking the ridges or crumbling the edges.
 
Be patient and your concrete pumpkin will reward you.
 

3. Forgetting to Seal It

An unsealed concrete pumpkin will absorb moisture and crack in freezing temperatures.
 
A quick coat of sealer extends the life of your concrete pumpkin for years.
 

So, How Do You Make a Concrete Pumpkin?

You make a concrete pumpkin by choosing a pumpkin-shaped mold, mixing fast-setting concrete to a thick consistency, filling the mold, adding a stem, and letting it cure fully before unmolding and sealing.
 
Once you know how to make a concrete pumpkin, it becomes one of the most satisfying fall crafts you can do.
