So, the above is my sole attempt at the art of the succulent terrarium. I have long thought that the idea of planting succulents in a terrarium or other drainage-less container was rather poorly conceived, but when I received these tiny sedums, I could not resist the idea.
The main problem with succulents in terrariums is that succulents like it dry and are prone to suffer when over-watered, and terrariums are pretty much designed to hold in moisture. However, at least in this case I found that the succulent still seemed happy as long as I watered carefully and infrequently.
The downside is that the roots grew down visibly into the drainage rocks and green goop (algae?) grew on the inside of of the glass. Not quite picture-perfect, but most casual observers only notice the cuteness.
How I did it:
- Bought champagne glass from thrift store and disinfected it.
- Used rocks for drainage, putting in the largest rocks (3/4 inch) first, then medium rocks, then small rocks. Layering the rocks in this way preserves the drainage space by keeping the small rocks and dirt from slipping all the way down.
- Finished up the drainage layer by adding a layer of perlite.
- Filled the remaining space with cactus and succulent potting mix and planted the sedum.
