The enclosed glass walls help to maintain high humidity levels that allow tropical plants to thrive in an indoor setting.
In this article we provide you with an in-depth understanding of tropical terrariums – what they are, how to set them up, plant selection options and maintenance strategies – so they can create their own lush indoor escape. Whether you are an experienced horticulturist or just getting started with indoor gardening, this guide will provide you with all the information you need to design your very own tropical oasis.
Types of Tropical Terrariums

Closed vs Open Terrariums: The Pros and Cons
When it comes to tropical terrariums, one major decision you’ll need to make is whether to keep your plants in a closed or open container. Closed terrariums are sealed containers that create their own miniature ecosystem.
They require very little maintenance and are ideal for plants that thrive in high humidity environments. However, they may not be the best choice for those who want a more hands-on approach to gardening or for plants that need good air circulation.
Open terrariums, on the other hand, allow for more air flow and movement through the container. This makes them a better choice for plants that require less moisture or those that need fresh air circulation.
However, they will require more watering and misting than closed terrariums. Additionally, they will not be able to house certain species of tropical plants that prefer high humidity levels.

High Humidity vs Low Humidity Terrariums: Choosing the Right Environment
When selecting a tropical plant species to grow in your terrarium, it’s essential to consider its humidity requirements. High humidity terrariums are ideal for plants such as ferns and mosses which thrive in moist environments. These types of terrariums typically have a lid or top cover which helps trap moisture inside.
Low humidity terrariums are better suited for succulent or cactus species which prefer dry soil conditions with occasional watering. A well-ventilated open container is perfect for these types of tropical plants since they do not require high levels of moisture in the air.
Moss Terrariums & Fern and Tropical Plant Terrariums: Creating Your Own Miniature Rainforest
Moss is an easy-to-care-for plant species that thrives in humid environments making it perfect for use in a terrarium. A moss terrarium creates a look that mimics the feel of a miniature forest floor. These types of terrariums are typically simple in design and require little maintenance.
Fern and tropical plant terrariums are perfect for adding color and texture to your indoor space. These types of tropical plants require high humidity levels, making them perfect for closed terrariums.
They come in all shapes, sizes, colors, and textures which makes it easy to find the perfect species to fit your personal style. Some popular fern species include Boston Ferns and Maidenhair Ferns while popular tropical plants include Philodendrons and Snake Plants.
Setting up a Tropical Terrarium

Choosing the right container
The first step in setting up a tropical terrarium is selecting the right container. The container must be large enough to accommodate the plants and provide adequate space for growth.
It’s important to choose a clear container because it allows light to penetrate and provides an unobstructed view of the plants inside. Glass containers are ideal because they don’t react with moisture or heat, and they’re easy to clean.
Soil and substrate selection
The soil and substrate in a tropical terrarium should mimic the natural environment of the plants as closely as possible. A combination of peat moss, perlite, and vermiculite is recommended for most tropical plant varieties.
The soil should be moist, but not waterlogged, so that it will promote healthy root growth while preventing root rot. Adding sphagnum moss as a top layer can help retain moisture.
Lighting requirements
Lighting is crucial for successful plant growth in a tropical terrarium. Most indoor plants require bright, indirect light to thrive. A south-facing window or artificial light source is ideal, but avoid placing your terrarium in direct sunlight as it can cause damage to the plants inside.
Watering and misting techniques
The watering needs of your tropical terrarium will depend on several factors including climate, humidity levels, plant variety, and soil type. Generally speaking, most tropical plant varieties prefer consistently moist soil that never dries out completely but isn’t waterlogged either.
Misting is also an important aspect of maintaining proper humidity levels in your terrarium environment–use filtered or distilled water at room temperature to prevent shock from temperature changes on leaves. By following these guidelines for choosing a container and selecting appropriate soil/substrate types while also keeping track of lighting and watering needs, your tropical terrarium will thrive with minimal effort on your part.
Plant Selection for Tropical Terrariums

Popular Tropical Plants for Indoor Gardening
When it comes to selecting plants for your tropical terrarium, there are many popular options that thrive in indoor environments. Some of the most common tropical plants used in terrariums include ferns, bromeliads, orchids, and philodendrons.
Each of these plants adds a unique touch of greenery to your terrarium while also providing the necessary humidity and moisture levels required for tropical plant growth. Ferns are a great addition to any tropical terrarium due to their lush green foliage and low-maintenance care requirements.
They come in a variety of sizes and shapes, making them perfect for filling up empty spaces within your terrarium. Additionally, bromeliads are also popular due to their vibrant colors that add an exotic touch to any indoor garden.
Choosing Plants Based on Size, Shape, and Color
When selecting plants for your tropical terrarium, it is important to consider their size, shape, and color. This will ensure that you create a visually appealing environment while also ensuring that the plants do not outgrow or overcrowd the container.
For instance, if you have a tall container with limited horizontal space available at the base, then taller plant species such as bamboo or dracaena would be ideal as they grow vertically without taking up too much space. Smaller species like baby tears work well with ground cover while creeping fig is great for climbing around rocks or wood elements.
It is also important to choose plants with contrasting colors and textures so that each individual plant stands out within the container. For example; using different types of leaf shapes such as palmate leaves vs lobed leaves can make an impressive display when combined into one elegant arrangement.
Plants That Thrive in High Humidity Environments
Tropical plants are well known for their ability to thrive in high humidity environments, which makes them ideal for terrariums. Some of the most popular species that do well with high humidity levels include ferns, mosses, and orchids. Ferns require consistent moisture levels and are able to survive in humid environments due to their natural habitat found on rainforest floors and riverbanks.
Mosses also thrive in moist conditions due to their need for water to survive. Orchids are known for their stunning flowers but also require high humidity levels so that they don’t dry out.
When creating a tropical terrarium, it is important to select plants that are able to handle the moisture level range you intend to offer. Some plants might need more moisture than others depending on factors such as lighting and temperature, however, this should be researched prior to purchase so you can choose suitable plant species for your specific environment.
Maintenance Tips for Tropical Terrariums
Pruning and Trimming Techniques to Maintain Plant Health
One of the most important aspects of maintaining a tropical terrarium is proper plant care. Pruning and trimming techniques are essential to keep plants healthy, prevent overgrowth, and ensure a visually appealing display. When pruning plants, it is crucial to use sharp, clean scissors or shears to avoid damaging the plant.
Regularly removing dead or yellowed leaves will encourage new growth and prevent disease from spreading. If a plant becomes too large for the container, it may be necessary to trim back roots or even divide the plant into smaller sections.
Pest Control Measures to Prevent Infestations
Pest control is another critical aspect of maintaining a healthy tropical terrarium. Common pests include mites, scale insects, mealybugs, and aphids.
To prevent infestations, it is essential that you regularly inspect your plants for signs of pest activity and take action immediately if you notice anything suspicious. One effective method for controlling pests in a tropical terrarium is using natural predators such as ladybugs or praying mantises that feed on common pests.
Another option is using insecticidal soaps or oils that are safe for use on indoor plants but still effective at eliminating pests. It’s important to follow instructions closely when using any insecticide in your terrarium and always ensure proper ventilation during application.
Fertilizing Schedules to Promote Growth
Fertilization plays an important role in promoting healthy growth in your tropical terrariums. But knowing how much and how often to fertilize can be tricky as each plant has different nutrient requirements based on its size, species, environment & other factors.
Most fertilizers come with instructions on how much product should be used per gallon of water used; however don’t over-fertilize as this can cause more harm than good to your plants. A good rule of thumb is to fertilize once a month during the growing season and suspend feeding during the dormant season.
With proper maintenance, your tropical terrarium can thrive for years to come. By regularly pruning and trimming plants, using natural pest control methods, and following a fertilization schedule tailored to your individual plants’ needs, you can enjoy a flourishing indoor garden that adds color and life to your home or office.
Creative Ideas for Decorating Your Tropical Terrarium
Tropical terrariums are a beautiful addition to any home or office. They not only add a touch of nature, but they also provide a calming ambiance. However, adding natural elements such as rocks, driftwood, and seashells can enhance their beauty and create an enticing visual appeal.
Adding Natural Elements
The use of natural elements in tropical terrariums is one of the easiest ways to enhance their beauty. Rocks and pebbles add texture and depth while also serving as drainage systems for excess water. Driftwood or twigs can be incorporated into the terrarium to create height differences between plants while creating a natural feel.
Seashells can be added on top of soil layers to give the impression of waves washing up on the shore. However, it’s essential to ensure that these elements are clean and free from contaminants before adding them into your tropical terrariums.
Incorporating Miniature Figurines or Fairy Garden Accessories
Incorporating miniature figurines or fairy garden accessories is another way to add personality and charm to your tropical terrariums. These accessories come in various styles and sizes, making it easy to find ones that complement your theme or plants.
For example, you can add miniature garden tools like shovels or rakes if you have ferns in the terrarium as they create an illusion that someone is taking care of them. Miniature animals such as frogs, turtles, or butterflies can be placed among the plants for an enchanting look.
Creating Themed Terrariums
Creating themed tropical terrariums requires more creativity but pays off with impressive results. A desert oasis-themed terrarium could include cacti with sand-colored pebbles decorating the base layer while rainforest-themed ones could have vines and tropical plants creeping up the walls of the container.
To create an exciting terrarium theme, consider combining different natural elements and figurines that relate to your desired theme. You can also research various ecosystems to get inspiration on how to set up your tropical terrarium.
Adding natural elements, miniature figurines, or creating themed tropical terrariums is an excellent way to personalize and enhance their beauty. Remember to keep it simple yet creative while ensuring all elements are clean and not harmful to the plants or ecosystem within the container.
