Here is how I assemble them:
Choose succulents and container
Add layer of pea gravel to bottom
Next add layer of sand (These are both to help with drainage)
Then I place a small amount of potting soil (cacti soil) is best. This is found at garden centers.
I then place the succulents (some stepables will work as well. I prefer short plants)
Last but not least I add the mini decorations
Succulents need a lot of light, but they need little water. If placing your succulents outside, water about once a week or when soil is completely dry. Also, bring inside when outside temperatures are below 40 degrees. If keeping your mini garden indoors, water only about once every three weeks or so, and keep in the sunlight. I love miniatures, so I believe one of the best parts is finding all of the tiny decorations to place inside.
