Make a Desert Terrarium
A Desert themed terrarium is a fun project to make and it is something that is relatively easy to care for. You are using a variety of cactii and succulents which don't require a lot of water and are very tolerant of sunlight. You also do this kind of terrarium in an open dish which is easier to make than in a closed container.
This tutorial take you through all the steps on how to make one of these terrariums.
I also have a video of this project here And Amazon.com has lots of nice Terra Cotta Planters and pots
Here is a list of materials you should have for this project: (Recommended but not all are necessary)
- A Container (terra cotta or arizona themed is perfect)
- Several plants, cactii or succulents (generally an odd number is best 3,5 or 7)
- 1 bag of sand, do not use sand you get at the beach - there are lots of contaminants
- Potting Soil, can be specifically for cactus or can be general potting soil
- A dozen stones in a variety of shapes and colors, go find them!
- Pebbles, Pearlstone or small rocks as drainage in bottom of container (1 or 2 cups is enough)
- Spanish Moss or Sphagnum Moss (Acts as a barrier so soil doesn't work its way down into the bottom of the dish or pot
- Arizona or desert themed ornaments

The Basic Layout
The illustration here on the left shows the basic layout for your desert terrarium. It is very similar to a regular terrarium but here are some things to note.
If you are using some large stones you should embed them rather deep into the soil. I put a couple of inches of soil in the dish, placed the stones then placed more soil.
The sand is also something not seen in a regular terrarium. I have put a thin layer of sand on the top of the soil. This was before placing the plants. Then after the plants were placed I touched it up with more sand.
Here is the basic Procedure:
- If there is a hole in your dish place a small piece of screen over it to protect from soil and stones falling out
- Place about an inch of pebbles or pearl stone in the dish
- Place a half inch to inch layer of activated charcoal (this purifies the water and soil and is totally optional in an open dish like this
- Place an inch thick layer of sphagnum or spanish moss (this prevents soil from seeping down into the bottom of the dish)
- Fill about half the intended final volume with soil
- Place your larger stones and arrange them in a pleasing manner
- Place the remainder of the soil
- Put your plants in an attractive arrangement and one nice way to do it is to try to get a plant or two between the stones and try to get one or two of them on a higher level. The whole arrangement is shaped like a volcano with the center of the dish being where the highest point is.
- Place some smaller colored stones in the dish
- Touch up the sand by adding more sand
- Add any ornaments or artistic touches (I have added a lizard)
Care of your terrarium
The plants have been shocked by being transplanted so for the first week you need to watch them carefully. Keep any tags or guidelines that came with the plants. These are valuable instructions that will help you in watering and sunlight needs.
Further Notes
I bought several different kinds of succulents and cactii from a local home improvement store. This kind of plant often has a plastic container that is full with a number of plants. i gently separated them and used them both as individuals and as small clusters. I also cut away a lot of the excess roots before I planted them in my terrarium.
