12 Inch Bell Jar Bonsai Terrarium

Preparing the Container

Cleaning the Bell Jar 

Start by thoroughly cleaning your pitcher glass to remove any dust, debris, or residues. This step is crucial to prevent any contaminants from affecting the growth of your bonsai or the overall health of your terrarium.

Adding a Drainage Layer in Bell Jar Bonsai Terrarium

Place a layer of small pebbles or rocks at the bottom of the pitcher glass. This layer will help with drainage, preventing water from stagnating at the bottom and causing root rot.

Creating the Layers

Add the layers provided with the terrarium kit.

How Much Substrate to Add

The substrate layer should be deep enough to support the roots of your bonsai, typically around 2-3 inches. Ensure it’s level and lightly compacted to provide a stable base for planting.

Planting the Bonsai in Bonsai Terrarium

Preparing the Bonsai Roots

Gently remove your bonsai from its pot and carefully loosen the roots. Trim any excessively long or damaged roots with bonsai scissors to promote healthy growth.

Positioning the Bonsai in the Terrarium

Create a small hole in the substrate and place the bonsai’s roots inside. Ensure the tree is standing upright and stable, then fill in around the roots with additional soil, lightly pressing it down to secure the tree in place.

Adding Decorative Elements

Incorporating Rocks and Pebbles in Bell Jar Bonsai Terrarium 

Decorative rocks and pebbles can enhance the natural look of your terrarium. Arrange them around the base of the bonsai to create a miniature landscape.

Using Moss and Other Plants

Adding moss can help maintain moisture and give your terrarium a lush, green appearance. You can also include small plants or succulents to add diversity and texture to your design.

Watering and Care

Initial Watering Instructions

After planting, give your bell jar bonsai terrarium a light watering to settle the soil and hydrate the bonsai. Use a spray bottle to mist the inside of the glass, ensuring even moisture distribution.

Long-term Care and Maintenance

Maintain a regular watering schedule based on the needs of your bonsai species. Monitor the humidity levels and mist as needed to keep the environment moist but not waterlogged. Prune your bonsai regularly to maintain its shape and encourage healthy growth.

Lighting Needs in Bell Jar Bonsai Terrarium

Best Lighting Conditions for Bonsai Terrariums

Bonsai trees need plenty of light to thrive. Place your terrarium in a location where it can receive indirect sunlight for several hours a day.

Using Artificial Light vs. Natural Light

If natural light is insufficient, consider using a grow light to supplement the lighting needs. LED grow lights are energy-efficient and provide the necessary spectrum for photosynthesis.

Troubleshooting Common Issues

Dealing with Mold and Mildew

Mold and mildew can be a common issue in high-humidity environments. Ensure adequate air circulation and avoid overwatering to prevent fungal growth. If mold appears, remove it promptly and adjust your care routine.

Preventing Overwatering in Bell Jar Bonsai Terrarium

Overwatering is a common mistake that can lead to root rot. Check the soil moisture regularly and only water when the top layer feels dry to the touch.
