To make a terrarium, you’ll need a glass container, gravel, potting soil, and dwarf houseplants.
1. Choose a container. You can use a fishbowl, large glass vase, or a small conservatory created just for a terrarium. Generally, a terrarium should be made with a clear glass vessel that’s partially or entirely closed. Unlike most plant containers, it should not have a drainage hole.
2. Add 2 to 3 inches of gravel to the bottom of the container. This looks pretty and helps with soil drainage. Then add at least 4 inches of potting soil.
3. Plant. Dwarf houseplants are the best choices. Your Lowe’s garden center has a great assortment.
Combine several types:
- Use a tall plant to add structure and height.
- Add a creeping groundcover to spread at the base.
- Make a focal point that’s colorful and bright.
4 (optional). Decorate. You can create a miniature forest using ferns, bark, and pinecones. Or, pack the container full of tropical plants to look like a jungle, add figurines to make a fairy garden, go Jurassic with a dinosaur, or Zen it up by adding a small cluster of polished stones.
Terrariums don’t require much water. The enclosed glass reduces airflow around the plants and helps keep the whole environment moist. Give your terrarium a good spritzing when the soil feels dry. The plants will thrive beautifully in this miniature ecosystem.
