Think aquarium – but for plants.
Made in a glass container, not unlike an aquarium, it is planted to look like a miniature garden or forest enclosed in its own little world. The beauty of this is that not only is it easy to make, it does liven up the living space with a little bit of greenery and better air quality, especially if you’re stuck many storeys high and deprived of any form of gardening. Terrariums are easy to make, low maintenance and can last a long time with minimal water. Plus, they are truly adorable so here’s a couple of tips and tricks to help you be on your way.
What you need:
- A clear glass jar, vase, bowl, glass, or whatever interesting glass container you have on hand
- Rocks, pebbles or recycled glass chunks
- Activated charcoal (sometimes called activated carbon)
- Potting soil appropriate for your plants
- Moss (optional)
- Figurines, sticks or decorative items (optional)
- Various small plants
- A scoop, spoon or shovel
STEP 1: Prepare the Container
Remove any price tags or stickers from your vessel and wash both the interior and exterior thoroughly to ensure that there are no unwanted residues that could affect the health of your plants. Envision how you want to arrange your plants inside the jar.
STEP 2: Add Your Drainage Layers
Once the container is ready, fill the bottom with rocks or pebbles. This is to create a false drainage layer so water can settle and not flood the plant. The depth of the rocks totally depends on the size of your container, but aim for 1/2″ to 2″.
STEP 3: Add the Activated Charcoal
The charcoal looks exactly like what you would expect it to and it’s messy. Sometimes it comes as small granules and other times it comes as shards—either works. You don’t need much, just enough to cover the rocks. The charcoal will improve the quality of your little world including reducing bacteria, fungi and odors.
STEP 4: Add Soil
Again, cactus and succulents need a special soil compared to most other plants, so be sure to get the appropriate bag depending on which plants you’re using. 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.
STEP 5: Plant
Take your plant out of the pot and break up the hard soil ball until you get down to the roots. If you’re breaking the plant into multiple parts, be gentle. You may also want to trim the roots if they are especially long. Don’t worry, they’ll grow back. Using a spoon, your fingers, the end of a brush, or even a pencil, dig a well to place your plants roots in. Add more soil around the top and compact the soil down around the base of the plant. Continue placing your little plants in the container and try to keep them away from the edges. The leaves are likely to touch the sides but aim to keep them away as much as possible.
STEP 6: Add Accessories
After you’re done planting you can add little accessories like a blanket of moss (dried or living), little figurines, old toys, glass beads, shiny metal object, sticks, stones, or even a layer or rocks. This is your little world and you can put whatever you’d like in there.
STEP 7: Clean and Water
You’ll likely have dirt all over the sides of the container, so wipe them down so you can enjoy the beautiful living world inside. Give the terrarium a little bit of water. Unlike most of your house plants, a terrarium doesn’t need to soaked: just a couple of shots of water should get it started.
Tips & Tricks
– Over time, monitor your terrarium’s water needs based on how dry the soil is. For terrariums with closed lids, if water is dripping down from the top, open the lid to let some evaporate. Likewise, you may need to add more if it looks parched. You shouldn’t need to water them very often.
– If leaves die or wilt, remove them from the terrarium immediately to maintain the health of the little eco system. If an entire plant dies, take it out.
– Don’t place in direct sunlight. Remember that these are essentially little greenhouses and direct sunlight through the glass will trap heat and scorch the plants. Place in indirect light for best results.
