DIY Overview: The Intricacies of a Carnivorous Plant Terrarium
Creating a carnivorous plant terrarium is a different ballgame altogether compared to your typical tropical terrarium. These insect-eating wonders are exotic, peculiar, and extraordinarily specific in their needs. After all, could we expect anything less from plants that have evolved to feed on insects?
Undoubtedly, these beauties require careful thought and consideration in terms of their setup and maintenance. But for avid plant enthusiasts and brave explorers like us, the thrill of unlocking the secrets of these unusual species and seeing them thrive in a carnivorous terrarium is an unrivaled reward.
Before we embark on this extraordinary journey, let’s take a look at some fundamental considerations.
1. Not All Carnivorous Plants Are Created Equal
A mesmerizing plethora of carnivorous plants await you, each more captivating than the last. Sticky-haired sundews, seductively long tubes of pitcher plants, and spiky traps of Venus flytraps — the world of carnivorous plants is rich and diverse.
Despite their shared penchant for a meaty meal, these species hail from different environments, predominantly boggy terrains. It’s this low-nutrient, acidic soil (particularly deficient in nitrogen) that nudged these plants towards carnivory in search of alternative nutrient sources.
This diversity necessitates bespoke terrarium conditions for each species. For instance, tropical species like sundews and pitcher plants are perfect for classic hot and humid terrarium conditions, but temperate species like Sarracenia or Venus Flytrap demand a completely different environment.
2. Carnivorous Plant Terrariums Require Very Specific Care
Emulating the low-nutrient boggy environment is only one aspect of caring for these exotic beings. Carnivorous plants often require significantly more light and possibly more moisture than your average terrarium plant. Therefore, pairing them with your usual tropical flora might not be straightforward.
What’s more, these intriguing beings are incredibly fussy about water purity. Only reverse-osmosis water, distilled water, or rainwater will do. Tap water, or even bottled drinking water, can cause a potentially fatal mineral buildup and damage the roots.
3. Your Container Choice Dictates Your Feeding Options
Interestingly, while insects are a preferred diet, carnivorous plants can derive their energy from photosynthesis just like typical plants. Hence, they can often manage well in a closed terrarium setting. However, if you wish for your plants to attract their own food, an open terrarium will be necessary, unless you plan to feed them directly.
Balancing the openness of a terrarium with the high moisture and humidity requirements of these plants might present some technical challenges. But don’t worry! We’ll guide you through all you need to consider.
Next up, we’ll delve into the best carnivorous plants to house in your terrarium.
Best Carnivorous Plants for Terrariums
Although these plants can adapt to the hot and humid conditions of a tropical terrarium, they each have unique wants and needs. You’ll need to cater to your terrarium setup accordingly.
Pitcher Plants (Nepenthes and Cephalotus)
With their striking hanging “pitfall traps” and elongated fleshy tubes, pitcher plants add an exotic flair to a terrarium. While Nepenthes are common and suited for terrariums as they prefer high moisture and humidity (with excellent drainage), they can grow BIG. Hence, they’re more suitable for large, tank-style terrariums. Alternatively, Cephalotus follicularis, the Australian Pitcher Plant, is smaller and more versatile.
Sundews (Drosera)
Known for their sticky hairs and the sparkling droplets they produce, sundews are among the largest and most diverse groups of carnivorous plants. Their small size makes them manageable for terrarium projects. Plus, they’re one of the easiest to keep, provided you pick a suitable tropical species.
Butterworts (Pinguicula)
Butterworts, or “Pings,” resemble little carnivorous succulents with their fleshy rosette foliage. The buttery residue on their leaves gives them their name and their effective insect trap. Their small size makes them an excellent fit for desktop projects. Plus, they’re arguably the easiest of all the carnivorous terrarium plants, with no extra requirements. Bonus: they bloom with pretty, delicate flowers!
Carnivorous Plants to Avoid for Your Terrarium
Choosing the right plants for your carnivorous plant terrarium is crucial. Some plants, despite their fascinating carnivorous tendencies, may not be the best fit for a terrarium environment. This is primarily due to their need for specific growing conditions that are difficult to replicate within the confines of a terrarium. So, while considering a terrarium for carnivorous plants, here are a few species you might want to reconsider:
- Venus Fly Trap (Dionaea muscipula): The Venus Flytrap is one of the most recognizable carnivorous plants. However, it’s not the most suitable candidate for your carnivorous plants terrarium. Despite the image of the Venus Flytrap being the epitome of the carnivorous bog plants, they are not fans of constant humidity or high temperatures. Moreover, they require a winter dormancy period, during which they almost die off, only to revive in the spring. This phenomenon, although natural and healthy for the plant, is difficult to manage in a typical pitcher plant terrarium setup.
- American Pitcher Plants (Sarracenia and Darlingtonia): The American Pitcher Plants, including the trumpet pitchers (Sarracenia) and the Cobra Plant (Darlingtonia), may seem like appealing additions to your carnivorous terrarium. They can indeed add a different aesthetic with their tall, slender growth. However, similar to the Venus Flytrap, these plants also demand a winter dormancy period. Their rapid growth and height make them more suitable for a fish tank carnivorous plant terrarium or a larger bog terrarium. Moreover, if your terrarium is not spacious enough, these plants can quickly outgrow it, making the overall terrarium setup more challenging to manage.
- Temperate Sundews (Drosera): Although tropical sundews make for an excellent terrarium addition, their temperate counterparts are a different story. The temperate sundews also require a winter dormancy period, which is challenging to achieve within a closed pitcher plant terrarium.
- Temperate Pings (Pinguicula): The temperate species of Pings or Butterworts are known for their beautiful rosettes and insect-catching capabilities. Despite these fascinating attributes, they, too, are unsuitable for your carnivore terrarium. The reason? These plants, like temperate sundews, also need a winter dormancy period. The fluctuating environment they require can be tough to maintain in a pinguicula terrarium setting.
While these species are captivating, they may not be the easiest carnivorous plants to manage in a terrarium. But don’t be discouraged! The world of carnivorous plants is vast, with plenty of varieties that are well-suited to terrarium life. Always consider the natural habitats and needs of your selected plants. A successful carnivorous plant terrarium is about replicating nature’s balance in a scaled-down, indoor environment. In the end, your efforts will result in a thriving, vibrant miniature ecosystem you can be proud of.
undamental Layers for a Carnivorous Plant Terrarium
Drainage Layer
Contrary to what you might believe, despite being native to swampy conditions, carnivorous plants cannot endure constant water-logged conditions. Like other plants, their roots need access to oxygen.
Thus, the incorporation of a drainage layer in your terrarium is essential. This layer acts as a reservoir for excess water when your watering enthusiasm gets the better of you. We won’t hold it against you.
When considering materials for this layer, it’s crucial to pick something inert to avoid the risk of mineral leaching that could potentially damage your carnivorous plants.
Lava rock stands as an excellent choice for this purpose. It’s not only lightweight but also highly porous, promoting aeration within the layer. Bonus point, larger chunks can double up as elements in your hardscape design!
Soil/Substrate for Carnivorous Plant Terrarium
Ensuring that your terrarium soil is nutrient-free and inert is critical for the health and survival of your carnivorous plants.
It might seem like a horticultural paradox, but carnivorous plants require a different set of terrarium layer rules.
Peat moss, known for its moisture-retaining properties and low nutrient content, is often used as a base for carnivorous plant soil. However, it raises sustainability concerns, making it a less favored option for many enthusiasts.
In my terrarium constructions, I opt for coco coir as an eco-friendly alternative. Some online plant growers affirm its suitability for carnivorous plants, although thorough rinsing is needed to remove any lingering minerals.
Sphagnum moss is another frequent choice due to its superior water retention capabilities.
Mike King, a specialist from Shropshire Sarracenias in the UK, finds success using a peat-free mix comprising “one part perlite, one part fine or coarse Cornish grit, and two parts fine-milled bark,” as reported by The Guardian.
While Cornish grit might not be accessible to everyone, it essentially is silica grit. So, replacing it with horticultural sand or any other silica sand should work just as well.
Lighting for Carnivorous Plant Terrarium
Truth be told, carnivorous plants demand an extensive amount of light daily.
Even a well-lit window may not suffice for some of the larger species in your collection. While lighting needs can vary between species, artificial lighting often presents the most effective solution.
LED grow lights allow you to regulate the light intensity and duration received by the plants without any concessions. Typically, a 12-hour light cycle is advisable for fostering healthy plant growth.
