The beauty of a rich, flourishing landscape can be brought inside using terrariums, as the answer indicates. Terrariums are ideal statement pieces for the house because they are essentially self-sustaining ecosystems contained in frequently closed, glass pots. Visitors will be wowed by their unique beauty.
Even though terrariums are frequently low-maintenance environments, if the proper steps are not taken when planning and establishing these intimate, protected ecosystems, they may not succeed.
A healthy terrarium depends on wise plant selection. The best plants grow best in moist soils with regular exposure to indirect sunlight, should be relatively small, and thrive in humid environments.
When grown in a humid environment, cacti and other succulents don’t do well.
However, they can still develop well in terrariums. Make careful to choose a container without a lid, though. As a result, the humidity will remain substantially lower than it would if the container were sealed.
Keep in mind that every plant has varied requirements, which also applies to growing a variety of plants in terrariums. Once you’ve decided the succulents you want to cultivate in your terrarium, you should look up the requirements for each plant online or from a nearby nursery (such as soil, light exposure and watering needs).
Cacti can they survive in a sealed 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.
The majority of ferns are quite hardy and can withstand high humidity. 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.
Why don’t cactus thrive in terrariums?
Despite the diversity of terrariums, cactus and enclosed containers are a prescription for catastrophe. After all, when we attempt to grow arid plants, the excellent characteristics of a genuine terrarium that allow us to grow tropical plants work against us.
- Humidity Cacti are designed to grow in arid areas and cannot tolerate humidity, which makes sense considering they are a desert-dwelling plant. In contrast, since they trap moisture in the air inside the container, closed terrariums literally create dampness.
- Water Storage
- Retaining the proper amount of moisture in the substrate or foundation is necessary to establish a healthy water cycle in a terrarium. On the other hand, cacti, despite the fact that they truly enjoy water, will quickly perish in a wet environment.
- Cacti require efficient drainage to prevent excessive water retention in the substrate. A drainage layer is quite helpful in this situation, but a drainage layer that is overflowing with water can cause issues by wicking up into the substrate or by passively increasing humidity.
- Airflow
- The continual wind that cacti are subjected to in their natural environment helps to keep them dry. Due to the substantial airflow obstruction present in most terrarium pots, coupled humidity can be a serious issue.
So, is it wise to keep cacti in a terrarium? Probably not in the strict sense of the word “terrarium,” but with the appropriate technique and an open terrarium, we can definitely create a beautiful and useful work of natural art.
Succulents can they live in a terrarium?
For succulents, the planting media is essential. Succulents are ideal for terrariums because of their sluggish growth, but if the proper medium isn’t used, the condensation that could form could harm the tiny plants. Fill the container’s bottom with small rocks or gravel. An inch or so of charcoal is placed on top of this layer. This removes any pollutants and odors that may be present in the water. Sphagnum moss should next be added, followed by lightly wet cactus soil.
In the cactus mix, put the little plants, and then compact the dirt around them. To dig the holes and fill them in around the plants, a dowel or stick is useful. Plants should be placed at least an inch (2.5 cm) apart to allow for proper airflow. For the first several weeks, plants may require a Popsicle stick or small stake to hold them erect.
The really enjoyable part now is designing the terrarium. Add some seashells if you want a beach theme, or place some pebbles to go with the succulents if you want a desert theme. There are countless products that can be used to improve the terrarium’s natural appearance. Some growers even include porcelain figurines to heighten the whimsical atmosphere. Just make sure everything you put in the terrarium has been well cleaned to prevent introducing disease.
Is it possible to grow cacti in glass containers?
Fill the jar’s base with potting soil. Fill the glass jars’ bases with potting soil once they have been cleaned and dried. Succulents should be taken out of their plastic containers and placed in the glass jar. To prevent the succulent from moving around, fill the remaining space in the jar with potting soil.
Can you grow succulents and cacti in the same terrarium?
Everyone is talking about terrariums, and with good reason, if you read gardening and fashion websites. They are intriguing. An full ecology is housed within—your own miniature world to see develop and alter. Infinitely varied in terms of colors, forms, and textures, they are also stunning. Although cacti and succulents don’t normally thrive in terrariums, you can still use them successfully with a few straightforward modifications.
For your terrarium, pick a big, open container. Recognize that cactus and succulents require drier conditions with lower humidity and better air circulation than closed terrariums can provide, despite the fact that classic terrariums are closed.
Plant your succulents and cacti such that they aren’t touching one another or the terrarium’s sides. Succulents need space between them so they can eventually spread out and grow.
By transforming your finished terrarium into a fanciful environment incorporating pebbles, toys, figurines, plastic animals, and other treasures, you can take this trend to the next level. Make sure the products you purchase won’t corrode or break down in humid, wet environments.
Because most cacti and succulents require a lot of light, place the terrarium in an area that gets lots of bright, indirect sunlight. The terrarium shouldn’t be placed in direct sunlight or close to a bright window because the heat from these areas could kill the plants.
After your plants have been in the terrarium for a full seven days, water them for the first time. Watering should not be done before this since damaged roots require time to recover and establish themselves. Only when the soil begins to dry out should you rewater.
