Spooky Pumpkin Terrarium For Unique Halloween Decor

Learn how to make a spooky pumpkin terrarium for your Halloween decorating! This Halloween terrarium is easy to put together in minutes, even if you’ve never crafted before.

Skills Required: Beginner. You may be cutting out the front of a faux pumpkin if you can’t find a diorama version, and the rest is just simple cutting, taping, and placing items.

So I went to Michaels recently and stopped when I saw their big bin of pumpkins. Of course they had the standard pumpkins and even some different colors (teal, black, etc.). But what really caught my eye? Their 13″ diorama pumpkins.

I’m obsessed with fairy gardens and the precut opening gave me the potential to turn it into a pumpkin terrarium! What I also love is that it was really easy to grab some of the cute little Halloween fairy garden supplies because there is a whole section.

My point is, if you want to make a pumpkin terrarium (and who doesn’t?) for your Halloween decor, you can throw one together in just a few minutes using this tutorial.

Don’t forget: from playful pumpkins to spooky sights, Michaels has everything you need to MAKE it Spooky this fall!

putting sand and stone inside the pumpkin

Place a Base Layer

Step 1: Fill the bottom of the pumpkin with small rocks, even separating it into two sections with different colored rocks.

Step 2: Use charcoal or wood chips to separate sections and/or line the outside edge to add depth and give the appearance of a pathway.

Add Tea Lights and Accessories

Step 3: Carefully bury the tea lights into the rocks in various locations, turning them on beforehand.

Note, if using tea lights, they will remain ON at all times so as not to disturb the terrarium decor. Well, unless you get those tealights with a remote.

Step 4: Place Halloween-themed accessories like pumpkins, gravestones, skulls, etc. around the inside of the pumpkin, pressing into the rocks lightly to hold themselves up.

Step 5: Cut the stems off of fake succulents (2 – 3 for a large pumpkin) and place in open areas to appear like plants in a graveyard. Move other accessories as needed to make the scene appear cohesive.

Cutting out bat shapes from black paper using scissors

Make and Attach the Bats

Step 6: Cut small bat shapes out of black construction paper or cardstock either using a template or by drawing the shape. Cut 2-3 for a large pumpkin, about 2 inches wide.

Taping the bats inside the roof of the terrarium

Step 7: Cut a piece of fishing line about 4 inches long and tape to the back of a bat shape. Tape the other end to the top inside of the pumpkin and repeat with the other bats, varying the lengths slightly to achieve the appearance of bats flying in the night.
