Terrariums create an ecosystem for plants and animals, forming an alternative environment in which they can survive and even thrive. They consist of a clear plastic or glass container, with a tightly closed lid causing an increase in humidity. The small, creeping baby tears plant usually lives at least partially submerged in water and without a constant source of moisture the plant will wilt. A terrarium provides this environment for the plant in a place where it would not usually survive.
Place a 1- to 2-inch layer of gravel or pebbles down at the bottom of the terrarium. Since your container has no holes, this will help with proper soil drainage.
Add a 1/4-inch layer of charcoal on top of the pebbles or gravel. This will also help with drainage and control any soil odors that may occur.
Place a 4- to 6-inch layer of well-drained potting soil as the third layer. Create hills and valleys, adding to the visual appeal of the terrarium.
Remove the baby tears plant from its container and pinch off any dead leaves or branches. Scoop out a hollow of dirt in the terrarium in which the roots of the plant fit. Place the baby tear's in the hollow and backfill the dirt around the roots of the plant. Tamp down, and rearrange the soil as you please.
Mist the soil around the baby tear's plant heavily, moistening it. Place a cover on the terrarium. Saran wrap will work if you do not have a natural cover for the container.
Place the terrarium in an east or north facing window. Baby tears likes medium light and will not do well in strong, direct light. Turn the terrarium occasionally to keep the baby tears plant growing evenly in all directions.
Maintain the terrarium. Mist the soil occasionally as needed. If the surface fogs, remove the cover for a few minutes to let some water evaporate. Some condensation is perfectly fine. Prune the baby tears when needed, pinching off dead leaves and any branches you wish to keep in check.
