1. Choose a Container

Select a clear glass container with an opening wide enough to plant and maintain your terrarium.

2. Layer the Base

Add a layer of drainage material, such as gravel or activated charcoal, to the bottom of the container to prevent waterlogged soil.

3. Add Soil

Fill the container with a well-draining potting mix suited to the plants you’ll be growing.

5. Add Decorative Elements

How to Care for Terrarium Plants

Once you’ve chosen the perfect miniature plants for your terrariums, it’s essential to provide them with the right care. Here are some tips to help you keep your miniature garden looking its best:

Watering

Monitor the moisture levels in your terrarium regularly. While it’s essential to keep the soil moist, avoid overwatering, as this can lead to root rot. Use a spray bottle to water your plants lightly, ensuring the soil is evenly moist but not waterlogged.

Light

Pay attention to the lighting conditions in your home and place your terrarium accordingly. Most terrarium plants prefer indirect sunlight, so avoid placing them in direct sunlight, which can cause sunburn.

If your terrarium is in a darker area, consider using artificial grow lights to provide the necessary light for plant growth.

Removing Dead Leaves

Keep your terrarium plants looking tidy by pruning away any dead or yellowing leaves. This not only improves the appearance of your mini garden but also promotes healthy growth.

Fertilizing

While terrarium plants don’t require frequent fertilization, occasional feeding can help keep them healthy and vibrant. Use a diluted liquid fertilizer and apply it sparingly to avoid overfeeding.

Air Circulation

Ensure adequate airflow around your terrarium to prevent the buildup of excess humidity, which can lead to mold and mildew. Open the lid of closed terrariums occasionally to allow fresh air to circulate.
