These miniature worlds make a conversation-starting centrepiece, and they’re also a great green-fingered project for the whole family.

How to make a Jar Terrarium
1. First clean and dry your jar. If you use glass cleaner or a harsh soap, make sure to wash out the jar after and let it air out completely.
2. With a small enclosed terrarium, drainage is important. Layer the bottom of the Kilner jar with some small stones to help the water drain away from the soil. Start by adding a 1" layer of pebbles, followed by a thin layer of charcoal. The charcoal will help filter the water in your terrarium and will absorb odors — otherwise your terrarium may start to smell.
3. Next, add a thin layer of soil on top of the stones.
4. Remove the small plant from its pot and place it in the jar. Fill in the area around the plant with more soil, then top off the soil with another layer of stones.
5. You can add some cute embellishments to your terrarium. I found some tiny mushrooms and a small “fairy garden” sign near the floral section of my local craft store.
6. Place the ring back on the jar to give it a finished look, but leave the flat lid off so that the terrarium will have some air flow. Display your terrarium in a sunny spot, and occasionally water it with mist from a spray bottle.
