How to Care for Terrarium Plants

Terrariums are small ecosystems that can be self-sustaining for long periods of time, depending on the type of terrarium and the type of plants used. Plants in terrariums generally require less care than other plants, but the care they do require is unique.

Difficulty: Easy

Instructions

1. Place the terrarium in indirect sunlight. Terrariums trap in heat, and direct sunlight causes temperatures in terrariums to become too hot for most plants. Even plants which generally thrive in direct sunlight are given the best care if placed behind a transparent curtain or several feet away from a bright window.

2. Water the terrarium with a mister. Pouring water into a terrarium can dislodge the loose soil. Also, too much water in one area can cause harm, because terrariums have no drainage available.

3. Monitor the soil. Add water only when the soil becomes dry. If your terrarium is covered, moisture gets trapped inside and the terrarium may not need care for several weeks or even months.

4. Remove the lid as necessary for ventilation. It becomes necessary to remove the lid occasionally, because the glass in the terrarium fogs up making it impossible to see inside. Occasional ventilation also benefits the plants. Remove the lid for several days, once per month, or as necessary for fog to clear.

5. Remove dead leaves. Even the healthiest plants drop leaves. When you have the terrarium open for ventilation or watering, clear out any dead plant material. This material can attract harmful bacteria and pests.

6. Watch for signs of nutritional deficiency. Fertilization does not need to be a part of regular part of terrarium care. However, if plants show signs of nutritional deficiency, such as yellowing leaves or spindly growth, apply a dose of water-soluble fertilizer the next time you water.

Tips & Warnings

• Keep the lid on the terrarium. Only remove it when absolutely necessary. The terrarium lid is what traps in heat and moisture and keeps the ecosystem running.
