Bring a piece of the outdoors in by creating your own terrarium. They’re the perfect little ecosystem for your home and require minimal maintenance. It’s a brilliant way to upcycle old glass jars and vases that can be found in your home or local charity shops and bargain stores. All the other supplies can be found and bought at your local garden centre. As for the plants, the possibilities are endless, but aim for small cacti and succulents so they can easily fit into the glass containers.

Preparing the container

What you need: glass container, small rocks or pebbles

Wash and clean the container ready for planting. Then start planning the arrangement of your plants. Next add your drainage layers, fill the bottom with rocks or pebbles. This helps the water settle and not flood the plants. The amount of drainage depends on the size of the container but aim for the container to have ½ drainage layers.

Add the soil

What you need: soil

Time to add the soil, make sure to use the appropriate soil for cacti and succulents as they require different soil compared to plants grown in the garden. Add enough soil so the plant roots will have plenty of room to fit and then grow. Aim for a depth slightly greater than the height of the plant’s pot.

What you need: plants

Take your plant out of the pot and break up the hard soil ball until you get down to the roots. Then carefully place into the container, making sure it doesn’t touch the sides. Continue until all the plants are placed in the container. The add more soil around the top and compact it down around the base of the plant to ensure stays in place and can continue to grow.

Clean and water

Finish the terrarium by cleaning the sides as it probably got messy from the soil and charcoal. Then just add a little bit of water and your new terrarium is ready to go.

Top tips for keeping terrariums:

  • Don’t over water your terrarium, water based on how dry the soil is.
  • Don’t place in direct sunlight as they are in glass containers that act as a little greenhouses so direct sunlight may scorch the plants. Therefore, we advise placing your terrarium in indirect light for the best results.
  • If leaves die or wilt, remove from the terrarium to maintain the health of the plants.
