How to Make a Demijohn Terrarium

With the right supplies and technique, creating a Demijohn terrarium is easier than it looks, so keep reading on for our complete step-by-step guide on how to make a demijohn terrarium and bring a touch of nature into your home.

Supplies You Will Need to Make a Demijohn Terrarium

  • A demijohn bottle (can be found at thrift stores or online)
  • Small pebbles or gravel for drainage
  • Activated charcoal for filtering
  • Potting soil suitable for indoor plants
  • Various small houseplants of your choice (succulents, ferns, mosses, etc.)
  • Gardening tools such as a spoon, tongs, or chopsticks
  • Decorative elements (optional)

Step-by-step Guidelines on How to Make a Demijohn Terrarium

Step 1: Preparing Your Demijohn Bottle

Thoroughly clean your demijohn bottle with hot, soapy water and let it dry completely. You may also use a mixture of equal parts white vinegar and warm water to disinfect the bottle if needed. Make sure there are no cracks or chips in the glass as this can cause leaks and damage to your plants. Preparing the bottle beforehand is crucial as it will be difficult to clean and fix once your terrarium is complete.

Step 2: Adding Drainage Layer

The key to a healthy terrarium is proper drainage. Create a layer of small pebbles or gravel at least one inch thick at the bottom of your Demijohn bottle. This will ensure that excess water can drain out of the soil and prevent root rot. This layer also acts as a barrier between the soil and charcoal to prevent mixing.

Step 3: Adding Charcoal Layer

Activated charcoal is essential for filtering water, preventing bacteria growth, and maintaining a healthy environment for your plants. Add a thin layer of activated charcoal on top of the drainage layer to help keep the terrarium clean and fresh. Make sure the charcoal layer is thick enough to cover the entire bottom of the bottle.

Step 4: Adding Potting Soil

Choose a potting soil that is suitable for indoor plants and add a layer on top of the charcoal. The amount of soil you need depends on the size of your demijohn, but make sure it’s deep enough for your plants to root. Avoid compacting the soil too much to allow for proper drainage and aeration. If you’re using succulents, you may need to mix in some sand or perlite to increase drainage and prevent waterlogging.

Step 5: Planting Your Terrarium

Now comes the fun part – planting! You can get creative here and choose a variety of plants that will thrive in a closed environment. Start by removing your plants from their containers and gently loosen the roots. Place them in your terrarium, making sure they have enough space to grow and won’t touch the sides of the glass.

Choose a Variety of Plants

Use your gardening tools to position the plants and add more soil if needed. This is also a great time to add any decorative elements, such as small figurines or pebbles, to enhance the look of your terrarium.

Step 6: Maintaining Your Demijohn Terrarium

Terrariums are low-maintenance but still require some care to thrive. Keep your demijohn terrarium in a spot with indirect sunlight, as too much direct sunlight can cause the temperature inside to rise and harm your plants. Check the soil moisture level regularly, and water only when it’s dry.

If you notice any dead or decaying plant parts, remove them immediately to prevent mold growth. You may also need to prune your plants occasionally if they outgrow their space.

Following these simple steps, you can create a stunning demijohn terrarium that will add a touch of nature to your home decor. Remember to get creative with your plant choices and have fun with the design.

With proper care, your demijohn terrarium will continue to thrive and bring joy for years to come. Now go ahead and get started on your unique indoor garden!  So what are you waiting for? Get your hands dirty and bring some greenery into your home with a beautiful demijohn terrarium. Happy gardening!

Additional Tips and Tricks to Make a Demijohn Terrarium

1. If you are using a clear glass demijohn, try adding some decorative elements like colored sand or small pebbles at the bottom before adding the soil. This will add a pop of color and make your terrarium more visually appealing.

Adding Some Decorative Elements

2. When selecting plants for your terrarium, choose ones that have similar light and water requirements. This will make it easier to care for your terrarium over time.

3. Consider adding a layer of activated charcoal above the pebbles and below the soil. This will help filter the water and keep it fresh for your plants.

4. Use a long-handled tool, such as a chopstick or skewer, to reach difficult areas inside the terrarium when arranging your plants and decorations.

5. If you notice any condensation building up inside the terrarium, open the lid for a few hours to let in some fresh air. This will prevent mold or bacterial growth.

6. Remember to water your terrarium sparingly, as the enclosed environment will create its mini-water cycle. Only water when the soil feels dry to the touch.

7. Use a spray bottle filled with water to mist the leaves of your plants instead of pouring water directly onto the soil. This will help prevent overwatering and keep the soil from becoming too soggy.

8. You can also add a layer of sphagnum moss on top of the soil to help retain moisture and create a natural look for your terrarium.

9. If you notice any dead leaves or plants in your terrarium, remove them promptly to prevent decay and potential issues with pests.

10. Finally, have fun with your demijohn terrarium! Experiment with different plants, decorations, and styles to create a unique and personalized mini-ecosystem.

Have Fun With Your Demijohn Terrarium

Following these additional tips and tricks will help you create a beautiful and thriving demijohn terrarium that will bring joy to your home or office space. Happy planting! 

Precautions Need to Be Followed for Making a Demijohm Terrarium

1. Before starting the process of making a demijohn terrarium, make sure to wear gloves and protective eyewear. This will prevent any accidental cuts or scratches from the sharp edges of the glass.

2. Choose a well-ventilated area for assembling the terrarium. Working in an enclosed space can lead to inhaling harmful chemicals or fumes from the materials used.

3. Use sterile tools and materials to prevent any contamination. This includes using clean gardening scissors, sterilized potting soil, and distilled water.

4. If possible, choose plants that are pest-resistant and do not require frequent pruning. This will reduce the risk of introducing pests or diseases into your terrarium.

5. Keep in mind that different plants have different watering needs. Make sure to research the specific water requirements of the plants you choose for your terrarium.

6. Be cautious when handling cacti or other prickly plants. Use tongs or a thick cloth to protect yourself from potential injuries.

7. Avoid overcrowding your terrarium with too many plants. This can lead to competition for resources and hinder their growth. Make sure to leave enough space for each plant to thrive.

8. When adding decorations such as rocks or figurines, make sure they are clean and do not contain any harmful chemicals that can leach into the soil.

Adding Decorations Such as Rocks or Figurines

Following these precautions will ensure a safe and successful process of making your demijohn terrarium. Additionally, it is always a good idea to research the care requirements of specific plants before adding them to your terrarium. This will help you provide the best environment for your plants to thrive and create a beautiful and healthy miniature ecosystem. Happy terrarium crafting!
