Cactus are supposed to be easy to care for, right? I hope so, because I just finished building a little cactus garden that I’m planning on bringing to work to brighten up my boring cubicle. If my track record means anything, they will probably be dead by the end of the week, but my fingers are crossed that they will make it. Luckily, one of my cube mates is a master gardener, so I’m hoping she will give me tips on how to keep these cuties alive and well. 
I think they have a fair chance at surviving, because I did a lot of research on how to properly build a terrarium. I used three layers of organic material– a bottom layer of rocks, a middle layer of horticultural charcoal, and and a top layer of soil. The soil I used is specially formulated for cactus. I don’t really know what the difference between cactus soil and gardening soil is, but the man at the gardening store assured me that cactus soil was a safer bet. It was a little more expensive, and he might have just been trying to upsell me, but I’m a trusting gal, so I went with his suggestion.
I have high hopes for this little cactus garden. If I can keep it alive, then I might branch out and try to grow something else. Any suggestions for other easy to grow plants?
