Making a terrarium is a fun activity for parents and kids to share - they can be as small as a jam jar or as big as a tank. Let their imaginations flow with the design.
Pick up a see through glass container from an op shop. Any size or shape, depending on available space.
Fill the base of your container with decorative rocks or gravel, to provide good drainage.
Add an optional layer of charcoal to prevent the soil turning sour.
Place a layer of Spagnum/Irish Moss to prevent the soil draining down into the gravel. It also keeps the roots dry and healthy in their own little microcosm. See below.
Select plants with similar water requirements.
Position your plants and build the soil/potting mix around them.
Turn your terrarium into a magical world with shells, rocks, fairies, houses. Position near light, but not in direct sun. Water once a week with light spray (too much moisture will make it moldy).
