I recently fell in love with terrariums. They’re magical miniature environments so it was bound to happen at some point. I had a go at making a few for xmas and birthday presents.
There’s lots of tutorials around but the key things seem to be you need some gravel in the bottom for drainage as there’s no hole for the water to flow out of. You’re also meant to put plants that grow in similar conditions together. Succulents and cacti go together because they don’t need much water and ferns can go with mossy things that like dampness.
