Pumpkin-terarrium-lead-spooky: Find a unique container like this black pumpkin to build a festive Halloween terrarium!

Forget the typical glass bowl this time of year and make a Halloween terrarium. My daughter and I were browsing at Michael’s a few weeks ago and came across this black ceramic pumpkin. It has just enough room for a few plants and a couple of the Halloween themed ornaments they carried. It’s super easy to put this terrarium together — add cactus potting mix, plant the succulents and top it off with black sand, a sprinkling of glow in the dark pebbles and ornaments. Here are a few tips from my experience to help ensure your sucess:

Put your Halloween terrarium together

  • When you’re shopping for plants look for a mix of different shapes and foliage colors to get the most interesting arrangement. For this container avoid dark green and deep purple foliage though, they’ll disappear against the black background.

  • Give the succulents a good soaking before planting and premoisten the potting mix to helps the plants settle in more quickly.

  • Don’t be afraid to brush off some of the potting mix or break a root ball down a bit, if needed.This pumpkin has a shallow base that doesn’t hold a lot of potting mix. Fortunately most cacti and succulents are shallow rooted.

  • When trick or treating is done plan on givng your plants a brighter home that’s better suited for long-term growth.Though the wide opening allows a lot of light in when it’s facing a bright window This isn't a permanent home for them.

  • If you do need to water use a large eye dropper or watering can with a narrow spout and apply it lightly and carefully near each plant. This will help minimize washing any sand or pebbles away.
