Small space gardening – DIY terrarium
Potting up a simple terrarium is fun, quick and easy plus they make great gifts!
What You’ll Need
Vessel – glass jar or small glass bowl (why not check out the local op shops for nice glass containers)
Charcoal – this helps absorb any excess water and toxins
Plants – indoor plants work well (ferns, peperomia, calathea) or go for succulents – just don’t do them both in the same terrarium because they need different watering regimes. Why not use some cuttings from your garden – they are free!
Small pebbles for mulch
A small amount of moss to top off the layers
1. Place a 10-20mm layer of charcoal in the base of the vessel and cover with a 10- 20mm layer of moistened coconut fibre.
2. Add approximately 40mm layer of good quality, moist potting mix, doing a little landscaping to create a mound or slope if you like.
3. Add plants – If a terrarium is to be viewed from all angles, arrange the plants with the tallest one in the middle. If it’s viewed from one angle, position the tallest plants to the rear. A range of different heights, colours and leaf shapes will always create interest – you can even add a toy creature or two if you like.
4. Backfill with a thin layer of soil and mulch it all with small pebbles to secure plants and make it harder for fungus gnats to set up home in the soil.
5. A layer of moss acts as a good water indicator. It will dry out before the other plants – telling you it’s time to water! But be careful not to overwater the plants – test the mix with your finger before watering and if your finger comes out with some soil attached, it’s still wet and you can wait a few more days.
If this is a gift, let the recipient know to position the terrarium in the right amount of light for the plants, ideally a bright spot, such as a south-facing window sill. Water plants gently with a spray bottle when the moss looks dry.
