YOU WILL NEED
- Clean, glass containers with large enough openings to place plants inside. For example old mason or jam jars you might have lying around in the kitchen.
- Small stones (gravel, pebbles, broken pottery or something similar)
- Potting charcoal
- Scissors or landscaping accessories
- Choose a clear glass or jar, with or without a lid. You can re-purpose almost any old/used jar or glass. Almost any size will work, as long as it’s big enough to accommodate your plants. Don’t be afraid to experiment.
- Spread a 1- to 3-inch layer of charcoal, gravel, or pumice on the bottom of the container for drainage.
- Add enough potting mix to surround plant roots. Gently settle the rootball into the soil, then firm it into place. Add more soil as needed.
- Water 1-2 times per week, watering only the live plants and avoiding mosses. For an open terrarium, the soil should always remain barely moist, never too dry.
- To water, gently spritz the soil around plants with a spray bottle, taking care not to overwater. If your plants love moisture, cover the terrarium to maintain humidity, but open it occasionally to prevent the buildup of condensation. For drought-tolerant plants such as succulents, keep the container open at all times, and water sparingly.
- Closed terrariums should almost never need watering.
- Prune back dead foliage or overgrown plants as needed to prevent rotting.
- Terrariums thrive in natural, indirect light. Avoid placing in direct sunlight or other hot areas as you can actually cook the plants or burn foliage that is touching the edges of the vessel.
- Spray your terrarium daily to provide ample humidity.
