We had friends over recently, so I thought making terrariums would be a fun project to do together & it was!
Since it is a closed environment and creates its own ecosystem, a terrarium is perfect for someone who often travels or doesn't have time to attend to plants daily. It's not uncommon for a terrarium to be fine without water for 4 months or longer!
Here's what you need to make your own:
A clear glass container with lid. I snagged both of these glass jars for $3 from a local thrift store. You can choose all different shapes/sizes...the bigger the better.
Rocks for drainage (you can add decorative marbles, stones or gravel too). We used some colored glass pieces I had on hand from a stained glass project- mixed with some rock.Activated Carbon this helps keep the soil and air clean, also keeps any odor away. This is the same stuff you use in an aquarium and can be purchased at your local pet store.
Moss (Sphagnum), this is really optional. I like it for aesthetic purposes as it keeps the layers a bit separate.
Plants, we used air cleaning plants and ones that grow well in terrariums (fern, purple waffle). There are a variety of plants that will work well in a terrarium.
Here's some interesting history on terrariums, going all the way back to the Victorian era where they were very popular and referred to as 'Wardian Cases'.
