Bromeliads are plants that come from the tropical Americas. They come in lots of different colors, sizes, and shapes. They’re easy to take care of, which makes them popular houseplants.
One of the most common questions about bromeliads is whether or not they can be grown in closed terrariums.
The answer is Yes! They are well-suited to life in a terrarium because they are used to living in humid environments. In fact, many species of bromeliads actually require high humidity levels to thrive.
In this post, we will discuss everything you need to know about growing bromeliads in terrariums, including which species are best suited for this type of environment and how to care for them.
How Do Bromeliads Survive in a Closed Terrarium?
A terrarium is a self-contained environment in which bromeliad can thrive. A closed terrarium is one in which the lid is sealed, creating a miniature ecosystem.
Plants survive in a closed terrarium by recycling the water that evaporates from the plants’ leaves back into the soil. This process is known as the water cycle.
How The Water Cycle Works?
Water evaporates from the leaves of the plants in the terrarium and condenses on the walls of the terrarium. The condensation then drips down the walls and back onto the soil.
The water is then absorbed by the roots of the plants. The water evaporates from the leaves once again, starting the cycle anew.
In a closed terrarium, the water cycle is constantly recycling the same water, keeping the plants healthy and hydrated.
What to Consider When Choosing a Bromeliad for a Closed Terrarium?
Bromeliads are a type of plant that comes in many different shapes and sizes. Some bromeliads are more suited for closed terrariums than others.
Here are a few things to consider when choosing a bromeliad for a closed terrarium –
Size
From little plants that only reach a few inches in height to giant plants that can grow up to 10 feet tall, bromeliads come in a variety of sizes. It’s crucial to select a bromeliad for a closed terrarium that will fit comfortably inside of it without taking up too much room.
Light
To grow and thrive, bromeliads require bright, indirect light. A bromeliad will start to lose its color and possibly even die if it is kept in too much shade.
Make sure to select a bromeliad that can withstand the low light levels inside the terrarium when choosing one for a closed terrarium.
Water
Bromeliads are typically drought-tolerant plants that don’t need a lot of water. However, they do need their leaves to be regularly misted with water to prevent them from drying out.
So, when choosing a bromeliad for a closed terrarium, make sure to pick one that doesn’t require too much water.
Soil
From sandy to clay soils, bromeliads may grow in a variety of soil types. However, they thrive in soils with lots of organic matter and good drainage. Make sure to select a bromeliad that can survive the type of soil inside the terrarium when choosing one for a closed terrarium.
Temperature
Tropical plants called bromeliads like being hot and damp. A bromeliad will start to lose leaves if it is kept in a terrarium that is too chilly, and it could eventually perish.
Make sure to choose a bromeliad that can withstand the warm, humid conditions found inside the terrarium when choosing one for a closed terrarium.
How Do You Plant Bromeliads in a Terrarium?
If you’re looking to add a splash of color to your terrarium, bromeliads are a great option. These tropical plants come in a variety of colors, sizes, and shapes and can thrive in both low- and high-light environments.
They also don’t require a lot of water, making them a great option for terrariums.
Here’s a step-by-step guide to planting bromeliads in a terrarium –
Step 1: Choose the Right Bromeliad for Your Terrarium
There are over 3,000 species of bromeliads, so there’s sure to be one that’s perfect for your terrarium.
If you’re growing your bromeliad in a closed terrarium, opt for a species that doesn’t get too large. If you’re growing your bromeliad in an open terrarium, you can choose a larger species.
Step 2: Prepare the Potting Mix
Bromeliads prefer a well-draining potting mix. You can purchase a commercial potting mix or make your own by mixing equal parts of peat moss, perlite, and coarse sand.
Step 3: Plant the Bromeliad
Place the bromeliad in the potting mix and gently firm it around the plant. Water the plant well, making sure the potting mix is evenly moistened.
Step 4: Place the Terrarium in a Bright Spot
Bromeliads need bright light, but not direct sunlight. So, place the terrarium in a bright spot out of direct sunlight.
If you’re growing a bromeliad in a closed terrarium, you may need to provide additional light with a grow light.
Step 5: Water Your Bromeliad as Needed
Water your plant only when the potting mix feels completely dry to the touch because bromeliads don’t need a lot of water.
You might need to water your bromeliad more frequently in a closed terrarium because the humidity can make the potting soil dry out more quickly.
With just a few simple steps, you can add a beautiful bromeliad to your terrarium.
With proper care, your plant will thrive and add color and interest to your space for years to come.
Different Types of Bromeliads for a Closed Terrarium
There are many different types of bromeliads, but not all of them are well suited for a closed terrarium. Here are a few of the best choices for a closed terrarium –
Neoregelias
A particular variety of bromeliad that does well in closed terrariums is the neoregelia. They are small, compact plants that do not require a lot of space, and their leaves are often brightly colored, making them an attractive addition to any terrarium.
They are also relatively easy to care for and can tolerate a wide range of environmental conditions. They do not require a lot of sunlight and can even grow in low-light conditions.
One of the most important things to remember when growing neoregelias in a terrarium are to keep the soil moist but not too wet. Too much moisture can cause the leaves to rot, so it is essential to water them carefully.
Cryptanthus
Cryptanthus, or earth stars, are small bromeliads that are native to Brazil. They grow in shady, humid environments and are low-maintenance plants that require little care once they are established.
They typically reach only 6-8 inches in height, have wide, fleshy leaves that are often variegated or striped in shades of green, red, brown, and orange, and form a rosette shape. They are not heavy feeders and only need to be fertilized once every two to three months.
When watering, be sure not to over-water as this can cause the plant to rot. Instead, allow the soil to dry out slightly between waterings. Closed terrariums provide the perfect environment for cryptanthus to thrive.
Tillandsia
In the family Bromeliaceae, the genus Tillandsia contains about 650 species of perennial, evergreen, flowering plants that are indigenous to tropical and subtropical Americas.
The majority of Tillandsia species grow on trees or rocks in humid climates, but a few species (such as T. usneoides) are adapted to epiphytic life in dry climates.
They have silvery-green leaves and produce colorful flowers. Many Tillandsia species are cultivated as houseplants or as epiphytes.
This is an excellent choice for a closed terrarium because they are very adaptable to a wide range of growing conditions.
They can tolerate low light levels and high humidity and do not require much fertilizer. They are also relatively easy to care for and can be propagated from offsets (pups).
What Are Some Challenges of Keeping a Bromeliad in a Closed Terrarium?
Bromeliads are a beautiful and popular plant, often seen in terrariums. They are known for their striking foliage and vibrant flowers.
However, they can be a bit challenging to grow in a closed terrarium. Here are some of the challenges you may encounter –
Watering
Bromeliads are native to tropical regions and prefer high humidity. This can be a challenge to replicate in a closed terrarium.
It is important to water bromeliads regularly, making sure the soil is moist but not soggy. However, over-watering can lead to root rot, so be careful not to water too often.
Light
Bright, filtered light is essential for bromeliad growth. They will grow leggy and lose the color of their leaves if they do not receive enough light.
When utilizing a closed terrarium, be sure to pick a location with lots of light. You might also need to add artificial lighting, like a grow lamp.
Temperature
Warm temperatures, between 65 and 85 degrees Fahrenheit, are preferred for bromeliads. However, your plant may suffer if the terrarium’s temperature fluctuates too much between hot and cold.
Pests
Bromeliads are susceptible to pests, such as mealybugs, scale, and aphids. These pests can be difficult to control in a closed terrarium.
If you do find pests on your bromeliad, you can try treating them with insecticidal soap or neem oil.
Fertilizer
To be healthy, bromeliads require regular fertilization. But it’s crucial to use a fertilizer made specifically for terrarium plants.
Some fertilizers can be too strong for bromeliads and can burn their roots. Be sure to read the label carefully and follow the directions.
By following these tips, you can successfully grow a bromeliad in a closed terrarium.
