Brings nature indoors

I have always been a nature lover, and having an indoor terrarium allows me to bring a piece of the outdoors into my home. The lush greenery and vibrant colors of the plants create a soothing and refreshing atmosphere. It’s like having a mini garden right in my living room! Not only does it add beauty to my space, but it also connects me with nature on a daily basis.

Purifies the air

One of the most significant benefits of having an indoor terrarium is its ability to purify the air. Plants naturally absorb carbon dioxide and release oxygen through photosynthesis. This process helps to improve the air quality in our homes by removing harmful toxins and pollutants. Studies have shown that indoor plants can reduce the levels of volatile organic compounds (VOCs) in the air, which are commonly found in household products and can have adverse effects on our health. With an indoor terrarium, I can breathe easy knowing that the air in my home is cleaner and healthier.

Reduces stress and improves mood

In today’s fast-paced and stressful world, finding ways to relax and unwind is essential. Having an indoor terrarium has been a game-changer for me when it comes to reducing stress and improving my mood. The presence of plants has a calming effect on our minds and bodies. Studies have shown that being around nature can lower blood pressure, reduce anxiety, and promote feelings of happiness and well-being. Whenever I feel overwhelmed or stressed, spending a few minutes tending to my indoor terrarium helps me relax and recharge.

Choosing the right plants for your indoor terrarium

Choosing the right plants for your indoor terrarium

Low-light plants

When selecting plants for your indoor terrarium, it’s crucial to consider the lighting conditions in your home. If you have limited natural light, opt for low-light plants that can thrive in such environments. Some popular choices include pothos, snake plant, and ZZ plant. These plants are known for their ability to tolerate low light and require minimal maintenance.

Drought-tolerant plants

Another factor to consider when choosing plants for your indoor terrarium is their water requirements. Drought-tolerant plants are ideal for those who may forget to water their terrarium regularly or have a busy lifestyle. Succulents and cacti are excellent choices as they store water in their leaves and stems, allowing them to survive in dry conditions. These plants add a unique texture and shape to your terrarium while requiring minimal watering.

Small and compact plants

Since indoor terrariums are typically limited in space, it’s essential to choose plants that stay small and compact. This ensures that they don’t outgrow the container and maintain a balanced and visually appealing look. Some suitable options include ferns, mosses, and miniature varieties of tropical plants. These plants not only fit well in a terrarium but also create a lush and dense appearance.

Selecting the right container

When it comes to choosing a container for your indoor terrarium, the options are endless. You can use glass jars, fish tanks, or even repurpose old containers. The key is to select a container that is transparent and allows light to penetrate. This will enable your plants to photosynthesize effectively. Additionally, ensure that the container has proper drainage to prevent waterlogging.

Choosing the appropriate soil

The soil you use in your indoor terrarium plays a crucial role in the health and growth of your plants. It’s essential to choose a well-draining soil mix specifically formulated for terrariums or houseplants. Avoid using garden soil, as it may contain pests or diseases that can harm your plants. A good terrarium soil mix should be lightweight, porous, and retain moisture without becoming waterlogged.

Arranging the plants

When arranging the plants in your indoor terrarium, consider their growth habits and aesthetic appeal. Place taller plants towards the back or center of the terrarium, and shorter plants towards the front. This creates a sense of depth and balance. Experiment with different combinations and arrangements until you achieve the desired look. Remember to leave enough space for the plants to grow and breathe.

Adding decorative elements

To enhance the visual appeal of your indoor terrarium, consider adding decorative elements such as rocks, pebbles, or figurines. These elements can add texture, color, and interest to your terrarium. However, be mindful not to overcrowd the space, as it may hinder the growth of your plants. Strike a balance between the plants and the decorative elements to create a harmonious and captivating display.

Proper watering is essential for the health and longevity of your indoor terrarium. The key is to maintain a balance between underwatering and overwatering. Most terrarium plants prefer slightly moist soil, so water them when the top inch of soil feels dry. Avoid waterlogging, as it can lead to root rot and other issues. Use a spray bottle or a watering can with a narrow spout to water your terrarium gently.

Pruning and trimming

Regular pruning and trimming are necessary to keep your indoor terrarium looking neat and prevent overcrowding. Remove any dead or yellowing leaves to maintain the overall health of the plants. Trim back any overgrown branches or stems to encourage bushier growth. Pruning also helps to improve air circulation within the terrarium, reducing the risk of fungal diseases.

Monitoring humidity levels

Indoor terrariums create a humid microclimate, which is beneficial for most plants. However, it’s essential to monitor the humidity levels to prevent excessive moisture or dryness. Use a hygrometer to measure the humidity in your terrarium. If the humidity is too high, you can open the lid or remove it temporarily to allow excess moisture to escape. On the other hand, if the humidity is too low, mist the plants with water or place a small dish of water in the terrarium to increase humidity.

Preventing pests

Pests can be a common issue in indoor terrariums, so it’s crucial to take preventive measures. Inspect your plants regularly for signs of pests such as aphids, mealybugs, or spider mites. If you notice any pests, isolate the affected plant and treat it with an appropriate organic insecticide or insecticidal soap. Additionally, avoid overwatering and maintain good air circulation to discourage pest infestations.

Troubleshooting common issues with indoor terrariums

Troubleshooting common issues with indoor terrariums

Yellowing or browning leaves

Yellowing or browning leaves can be a sign of various issues, including overwatering, underwatering, nutrient deficiencies, or inadequate lighting. Assess the conditions in your terrarium and make the necessary adjustments. Ensure that you are watering your plants correctly, providing adequate light, and using a balanced fertilizer if needed.

Excessive moisture or mold growth

Excessive moisture or mold growth can occur if the terrarium is sealed too tightly or if there is poor air circulation. To address this issue, remove the lid or open it partially to allow fresh air to circulate. Wipe away any excess moisture or mold with a clean cloth or tissue. Adjusting the watering frequency and ensuring proper drainage can also help prevent excessive moisture and mold growth.

Wilting or drooping plants

Wilting or drooping plants can be a sign of underwatering, overwatering, or root rot. Check the moisture level of the soil and adjust your watering accordingly. If the soil is too wet, allow it to dry out before watering again. If the roots are affected by root rot, you may need to repot the plant in fresh soil and trim away any affected roots.



In conclusion, having an indoor terrarium is a wonderful way to bring nature into your home and enjoy its numerous benefits. From purifying the air to reducing stress and improving mood, an indoor terrarium can transform your living space into a tranquil oasis. By choosing the right plants, setting up the terrarium correctly, and providing proper care, you can create a thriving and visually appealing indoor garden. So why wait?
