How to Make Your Own Terrarium

Caring for Your Mini Garden

Keep close watch for the first few weeks to make sure that the plants are doing well. If any sign of disease appears, cut off the affected foliage or remove the plant to prevent the disease from spreading. If the plants still look healthy after three weeks or so, your terrarium has probably stabilized. From time to time, check in to be sure the plants are still thriving, and enjoy your miniature garden. If the lid is tight, you won't need to water for several months.

Note: Creating an open terrarium is exactly the same, but you can probably skip adding the activated charcoal step, and you'll need to water more often.
