Classic terrariums consist of glass containers with lids that create an enclosed mini ecosystem. Cacti look great in these types of terrariums, but they don’t survive very long, because cacti need regular airflow and low humidity to thrive. However, that doesn’t mean you can’t create a cactus terrarium. A open or dish terrarium isn’t closed off with a lid, solving the airflow and humidity problems and allowing you to display your cactus in a wide variety of containers.
Things You Will Need
- Potting soil
- Sharp builder’s sand
1. Choose a clear container that either has low sides or is wide enough to allow plenty of air to flow between the plants. Make sure the container allows for a few inches of space between the cacti and the inside wall of the container, both for airflow and to prevent damage to the easily-injured plants.
2.Fill the bottom 2 to 3 inches of the container with gravel to create a drainage system beneath your soil.No Matches Found. Please try your search again.
3. Cover the gravel with a half-inch layer of aquarium charcoal to help filter runoff water and manage odors.
4. Create a cactus-appropriate soil mix by combining 1 part sharp or coarse builder’s sand with 2 parts potting mix. Add this mix to your terrarium.
5. Put on gardening gloves to protect your hands and plant your cacti in the terrarium. Leave a few inches between each plant and in between the plant and the sides of the container.
6. Place in a sunny location for one week before watering to allow the roots to harden and callous.
7. Water until the soil is moist but not soaking wet. Water again when the soil has dried out. Avoid over watering to prevent root rot.
