Because of their modest size, lovely variations, and very simple maintenance, succulents are excellent terrarium plants. This article will teach you how to construct a succulent terrarium and will provide you with a step-by-step list of the materials you’ll need.
Generally speaking, the processes required to create a succulent terrarium are as follows:
- Select a terrarium vessel.
- sanitize the container
- Select and apply the bottom drainage layer.
- Add a filter to help with separation
- Apply a coat of charcoal
- Succulent soil mixture should be added before plants.
- Decorations
Succulents — can they survive in an open terrarium?
It’s wonderful to make terrariums, but your first thought presumably is, “Which plants should I chose for my terrarium?” The best plants for both open and closed terrariums will be discussed in this essay. Around 60 of the best plants for open and closed terrariums, including those that thrive in cramped conditions and can withstand high humidity and temperature swings, will be included on this list.
Air plants, or Tillandsia
Since they are epiphytes, air plants may survive without soil. For survival, these plants glue themselves to a host. Through their leaves, they take up water. For a number of reasons, air plants work best in open terrariums. One of them is that your air plant needs to be watered pretty frequently—about twice a week (apart from misting).
It is better to submerge air plants in water to water them, but this will be difficult in a confined terrarium. A few times a week removal of the plant will destroy the pattern. Because air plants don’t enjoy humidity or being wet, they are better suited for open terrariums. You must dry the plant after submerging it in water before putting it back in a terrarium.
You can utilize a variety of air plant species. The lengthy leaves that emerge from the core of air plants give them an incredibly gorgeous appearance. Top Tillandsia for terrariums include:
- Xerographic Tillandsia
- ionantha T.
- Houston
- Guatemala
- Tectorum
- Scaposa
- Aeranthos
- Stricta
- Peach, or capitata
- Caput-medusae
- Streptophylla
- Hondurensis
For your open terrariums, you can get a single air plant or a small collection similar to this. Here is a detailed guide to taking care of tillandsias.
Succulents
The best plants for open terrariums are succulents. To prevent overwatering succulents, be cautious when watering them. Succulents prefer drying out in between waterings and bright, indirect light. Ensure that the terrarium containing the succulents has an opening that is at least modest to medium in size. The following succulents make excellent terrarium plants:
- Jade tree (Crassula ovata). Deserts are where jade plants, which have heavy leaves, are found in nature. These plants require low humidity and strong light. Jade plants come in a variety of varieties; avoid picking any that can grow to be more than 4 feet tall! Select smaller varieties like “Mini Jade” or “Hobbit.” Jade plants require direct sunlight, good airflow, and rarely watering.
- Tiger Jaws, also known as Faucaria Tigrina, is a stunning plant with spiky leaves and star-shaped rosettes.
- Chickens and hens (Sempervivum). Chicks surround the main hen plant in these attractive succulent plants called “hens and chicks.” Hens and chicks can be used jointly or individually. They should only be planted in an open terrarium because higher humidity containers will cause them to decay.
- Aloe Vera, also known as the “medicine plant,” is a widely common plant with sharp leaves.
- the Chocolate Soldier, or Kalanchoe tomentosa
- Kalanchoe luciae, or the flapjack plant
- Ghost Plant, or Graptopetalum
- Alpine Aloe
- Haworthia, or the Zebra plant, has stunning leaves with striped surfaces.
- Sedum morganianum, often known as burro’s tail, has leaves that resemble beads.
- Gasteria
- Beautiful little round plants called lithops have a stone-like appearance. Read more here about Lithops care.
Cacti, or cactuses
Cacti need to be dry in order to look their best in terrariums. In closed terrariums with high humidity and poor airflow, these plants won’t survive. Make sure the container has a medium to large opening when making cactus terrariums. Because many cacti grow very enormous when they are fully mature, only choose little ones.
Baby tears, or Soleirolia soleirolii
a really lovely plant with leaves that have spots of various colors. These plants thrive in humid settings and adore dampness.
The adorable strawberry begonias are the ideal flowers for open terrariums. Be cautious because they require open terrariums with dry foliage. If not, the plant will begin to wilt.
Using croton plants, you may make incredible terrarium designs. You will need to prune these plants because they grow pretty tall. Make sure to grow them in terrariums with open doors. This plant will do well in Wardian case terrariums.
Best plants for closed terrariums (or better those with small openings):
It is always a good idea to have at least a little gap in the container, even though you can make a terrarium that is completely closed. Fully closed terrariums can fog up, make it difficult to care for plants, and yet result in rotting roots. Small, spherical glass spheres like this are the most common containers that produce lovely patterns.
There are many different types of bromeliad plants, and some of them enjoy warmth and humidity. The following are some of the top bromeliads for terrariums:
- Earth Star, or Cryptanthus It is the perfect plant for a sealed terrarium. They enjoy moisture, and
warmth. You can grow numerous varieties of Cryptanthus in a terrarium. Choose plants that don’t expand rapidly or get very large.
- Another lovely plant for a closed terrarium is neoregelia. Its lovely pink/violet blossom is of exceptional beauty.
- The magnificent Silver Vase plant, also known as Aechmea fasciata, has lovely flowers. This plant should be placed in a terrarium with a small to medium opening.
Long stems from this plant terminate in tiny, spherical, creamy-white blooms. They fit tall terrariums like Wardian enclosures and are ideal for humid conditions.
Popular and attractive plants like orchids work well in Wardian instances. Sphagnum moss must be present surrounding the roots of the plant.
The majority of carnivorous plants thrive in moist, nutrient-poor environments. For this reason, insect-eating plants capture them and consume them to obtain nutrition. These fascinating plants thrive in humid environments and intense direct sunlight.
Both open and closed terrariums are capable of supporting carnivorous plant growth. The only issue you might run into with carnivorous plants in tight terrariums is feeding them—they can have trouble collecting insects. You can either choose a terrarium with a tiny entrance or give your carnivorous plants their food by hand. Following are some of the top carnivorous plants for terrariums:
- Venus flytrap is a potential choice, but it will need to hibernate over the winter.
- The Tropical Pitcher Plants, often known as Nepenthes. Given that they grow very large, they might not be the greatest for small terrariums. Large terrariums can be used for planting plants, but the proper temperatures must be maintained. Nepenthes come in two varieties: Highlanders and Lowlanders. You may need to heat the terrarium during the day and chill it at night, depending on the type.
- Sarracenia, or American Pitcher Plants Since the majority of them grow huge and require winter dormancy, they are not the greatest plants for terrariums. However, you can choose Sarracenia for a terrarium, such as S. rubra or S. purpurea (purple pitcher plant). Select young plants, and make sure to give them a winter dormant period.
- Drosera, or sundews. For the winter dormancy, you must remove them, although they require bright light.
- Heliamphora, or Sun Pitchers. They enjoy high humidity, but they also require colder temperatures, as the nighttime temperature drops.
- Follicular Cephalotus Note that during the winter they require chilly temperatures.
- Pinguicula or butterworts
- Utricularia, or bladderworts
- Drosophyllum lusitanicum, also known as Dewy Pine, but only in an open terrarium. They require excellent ventilation and bright lighting.
Most ferns are tolerant of high humidity and are quite sturdy. Ferns give any terrarium depth. The following ferns make excellent terrarium plants:
- Bird’s nest fern (Aspleniumnidus)
- Little Holly Fern
- Hemionitis arifolia, sometimes known as heart fern
Nerve plants prefer high humidity, therefore they will do best in a closed container or, preferable, one with a tiny aperture. You must routinely monitor the soil’s moisture because they dislike soggy dirt.
Mosses are a wonderful addition to terrariums that are closed. You can utilize a wide range of mosses, such as moss balls or Golden Club moss plants.
Pilea microphylla, often known as artillery ferns, are stunning plants that are simple to grow and maintain in terrariums. They enjoy moist environments and direct, bright light. Additionally, the seeds shoot out with a popping sound!
High humidity and indirect light are favorable to creeping fig. It is a fairly resilient plant, but because it grows so quickly, you will need to clip it frequently.
High relative humidity and direct light are favorable to pothos plants. Additionally, they enjoy warm temperatures of about 70 degrees, so in the winter, be sure to keep them away from windowsills that are too cold. However, you will also need to constantly clip its leaves, so think about getting a terrarium with a little hole.
For an open terrarium, is activated charcoal necessary?
A terrarium can and will run successfully without a coating of charcoal. The important query is whether a covering of charcoal has a long-term beneficial impact on terrarium health.
Sadly, there isn’t any hard research demonstrating how well charcoal filters out harmful contaminants from a terrarium.
It makes sense in theory, and there is anecdotal evidence from seasoned terrarium builders that suggests it’s a useful addition, but like many terrarium-building decisions, it comes down to personal preference and trial and error.
Personally, I find that I utilize it less and less. I opted not to use charcoal in the project for my Essential Guide to Tropical Terrariums and instead used springtails to keep my terrarium clean. It’s still my healthiest, to be honest.
However, if you do decide to utilize it, adding a charcoal layer to your terrarium is a simple modification that I’ve found to have no significant drawbacks.
Charcoal can still be used as a drainage component when creating terrariums with a false bottom. So it won’t be much of a hindrance to your plants if it’s placed between your drainage rocks and your substrate.
Try adding extra terrarium moss instead of charcoal if you’re not keen on that. In any case, moss naturally filters water and is capable of removing contaminants like arsenic.
Are open terrariums watered?
The answer is yes, but not as regularly as standard indoor plants. Hardy plants that don’t require frequent watering typically make up the majority of the plants found in terrariums. Additionally, terrariums recycle water rather than letting it evaporate into the air like conventional indoor plants do.
How often do you have to water a terrarium?
Depending on a number of variables, you might water them (on average) once a month if they are closed. Every three to six weeks, open terrariums benefit from being watered. Check the soil to determine whether your plants need water and how much rather than watering on a timetable. Contact Ambius to take care of any terrariums you have to water and maintain.
Do terrariums need sunlight?
Although artificial light can also be employed, direct or indirect light is typically required. There are three different kinds of light that you can give your terrarium.
- blazing sunlight
- indirect lighting
- synthetic lighting
If you decide to put your terrarium in direct sunshine, you might want to take the cover off it because a closed terrarium might become too hot for the plants if the top is on.
Do terrariums need to be airtight?
If a terrarium is airtight, that’s OK, but we advise taking the top off occasionally (every week or so, ideally) to let some fresh air into your garden.
Can terrariums be made of plastic?
Sure! Containers made of plastic, such as acrylic ones, function perfectly. Additionally, anti-fog plastic containers are available; they are typically more expensive but prevent condensation buildup and improve visibility.
Do terrariums need air?
However, plants in closed or airtight terrariums recycle air. In the course of photosynthesis, sunlight encourages the formation of sugars during the day. Carbon dioxide is converted by photosynthesis into oxygen, which is then released into the terrarium.
Although you might wish to open the cover of a closed terrarium to let in some fresh air, the plants won’t be harmed.
Which kind of containers work best for terrariums?
For terrariums, the following containers are suitable:
- glass jars for candy
- aquariums with lighting
- jars with goldfish
- coffee makers
Even using a wine bottle is an option, but planting would be challenging because to the small opening.
Arid Plants
Succulents, air plants, and cactus are typically the plants best adapted for life in open terrariums.
Practically all plant types can survive without humidity and regular moisture. So it makes sense that humans would immediately turn to the plants that grow in arid areas at the other end of the curve.
Because cacti and succulents require similar maintenance, it is simple to combine them in an eye-catching combination of textures and forms. For more assistance with that, refer to our article on desert terrariums.
