Secrets to a Long-Lasting Terrarium
- Use a large enough glass container. A general equation seems to be, the larger the container, the better the chance the terrarium has to thrive.
- Use an adequate amount of soil. If plants are to grow, they will need some space.
- Use healthy plants and moss that have been inspected for insects and washed if needed. Select plants that have similar light and water requirements (e.g. woodsy ferns with moss, succulents with cacti.) See 19 of the most popular terrarium plants.
- Keep up with terrarium maintenance! This includes managing water and temperature levels (e.g. water occasionally and don't leave it in full sun all day). You might need to put a lid on your terrarium occasionally to help keep water in the system. You might need to remove dead leaves or scrub the sides of the container of algae fuzz.
- If all else fails, try again. Don't be afraid to restart your terrarium if mold takes over, plants die, or insects infest. Shake it all out, scrub out the container with water and a bit of bleach, and try again when it is dry. Fresh plants and soil!
