Drainage: If there will be live plants in the fairy garden, you might want to consider a container with drainage holes. If you’ve already fallen in love with a container without holes, don’t despair. A simple drainage layer will take care of the problem.Location: Where will be home to your fairy garden? The coffee table? The patio? If you’re planning to place your fairy garden on the patio in say full sun, don’t choose a glass terrarium for it. The terrarium will act as an oven and bake your plants the first day. On the other hand, a glass terrarium will work just fine for a shady outdoor area or coffee table in front of the couch.
