Source your containers from a thrift store or an antique store or scrounge around your house for an old jar. Even simple jelly jars or canning jars can make beautiful terrariums. They can be open or closed – it’s totally up to you. Everything else can be bought at your local gardening center.
As for the plants, the sky is the limit, but generally speaking look for small plants that you can fit inside your jar. Some plants will even have multiple stems so you can break them up even further. To ensure that your terrarium will be successful, keep succulents and cacti together and keep fern and tropical plants together, because they require different amounts of water and soil. You’ll want cactus soil for the succulents and regular old potting soil for everything else. The rocks are used as a false drainage layer, the activated charcoal helps keep the terrarium healthy, and the moss can be used for decoration and to help soak up water.
