Growing Succulents In Terrarium – The Aquarist’S Guide To Lush
As aquarium keepers, we’re obsessed with creating beautiful, self-contained worlds. We meticulously balance water parameters, cultivate lush aquatic plants, and watch our vibrant fish thrive. But what if you could bring that same passion for miniature ecosystems to dry land, right on your desk or windowsill?
I promise to show you exactly how to do just that. Many people try growing succulents in terrarium setups and end up with a mushy, rotten mess. Don’t worry, that won’t be you. We’re going to sidestep the common pitfalls and get it right from the start.
In this complete growing succulents in terrarium guide, we’ll walk through everything you need to create a stunning, healthy, and long-lasting miniature desert landscape. We’ll cover choosing the perfect container, layering your substrate like a pro, selecting the right plants, and mastering the art of ‘less-is-more’ care.
Let’s get our hands dirty and build something beautiful!
Why You’ll Love Growing Succulents in a Terrarium
If you love the “slice of nature” aspect of an aquarium, you’ll feel right at home with a succulent terrarium. It’s a different kind of aquascaping, but the core principles of design, balance, and biology are wonderfully similar.
Here are some of the key benefits of growing succulents in terrarium setups:
- Stunning Aesthetics: Succulents come in an incredible array of shapes, colors, and textures. You can create a living piece of art that looks like a tiny alien landscape or a miniature desert scene. They are a fantastic visual counterpoint to a lush, green planted aquarium.
- Low Maintenance (When Done Right): Unlike our aquatic friends who need regular water changes, succulents thrive on a bit of neglect. Once you establish the right environment, they ask for very little—perfect for the busy hobbyist.
- Space-Saving Greenery: Don’t have room for another 40-gallon tank? A beautiful terrarium can fit on a small shelf, a coffee table, or your office desk, bringing life to small spaces.
- A Creative Outlet: Just like aquascaping, designing a terrarium is a deeply rewarding creative process. You get to play with rocks, sand, and unique plants to build your own personal masterpiece.
The Golden Rule: Open vs. Closed Terrariums is Non-Negotiable
Before we go any further, we need to address the single most important rule in the world of succulent terrariums. This is the mistake that trips up 90% of beginners, so listen closely, my friend.
Succulents are desert plants. They hate, and I mean hate, sitting in damp, humid conditions with stagnant air. It’s a one-way ticket to root rot, fungal infections, and heartbreak.
This means you MUST use an open terrarium. A closed terrarium—one with a lid—is designed to trap moisture and create a high-humidity environment. This is fantastic for mosses and ferns, but it is a death sentence for succulents.
Always choose a glass container with a wide opening, like a fishbowl, a glass vase, or a specialized terrarium bowl. This ensures proper airflow, allows moisture to escape, and gives your desert dwellers the arid environment they crave.
Your Complete Growing Succulents in Terrarium Guide: A Step-by-Step Build
Alright, let’s get to the fun part! Building your terrarium is like setting up a new tank—the foundation is everything. Follow these steps, and you’ll be on the path to success. This is how to growing succulents in terrarium setups works from the ground up.
Step 1: Choosing the Perfect Glass Home
Your container sets the stage. Look for clear glass so you can see the beautiful layers you’re about to create. Remember, the opening must be wide to ensure good air circulation. A container that is deeper than it is wide can sometimes trap moisture, so a bowl or shallow cylinder shape is often ideal.
Step 2: The All-Important Drainage Layer
Since your terrarium has no drainage holes, we need to create an internal drainage system to protect the roots from sitting in water. This is a non-negotiable step for long-term health.
- Start with a 1-2 inch layer of coarse material at the bottom. Small pebbles, gravel, or even decorative glass beads work perfectly. This layer creates a reservoir where excess water can collect away from the soil and roots.
- Pro Tip: Add a very thin layer of activated charcoal on top of the gravel. You know this stuff from your aquarium filters! It helps to filter the water and prevent any musty odors or bacterial growth over time.
Step 3: Crafting the Ideal Soil Mix
Do not use regular potting soil or garden soil. It’s far too dense and holds way too much moisture. You need a gritty, fast-draining mix specifically designed for cacti and succulents. You can buy pre-made bags at any garden center, or you can easily make your own.
DIY Succulent Soil Recipe:
- Two parts potting soil
- One part perlite (the little white rocks that add aeration)
- One part coarse sand or small poultry grit
Add a layer of this soil mix that’s deep enough to accommodate your succulents’ root balls, usually 2-4 inches depending on the size of your container and plants.
Step 4: Selecting Your Succulent Superstars
This is where your personality shines! Choose a variety of succulents with different heights, textures, and colors. Think like an aquascaper: you want a “focal point” plant, some “mid-ground” fillers, and maybe a low-growing “carpeting” variety.
Some excellent choices for terrariums include:
- Haworthia (Zebra Plant): Striking patterns and they tolerate slightly lower light.
- Gasteria (Ox Tongue): Interesting tongue-like leaves and very hardy.
- Echeveria: Classic rosette-shaped succulents. They need plenty of light to avoid stretching.
- Sedum (Stonecrop): Many varieties act as a great groundcover or “spiller” over the edge.
- Sempervivum (Hens and Chicks): Form tight, beautiful rosettes and produce little “chicks.”
Step 5: Planting and Arranging Your Miniature Landscape
Gently remove your succulents from their nursery pots and dust off the excess soil. Arrange them in the terrarium, starting with your largest plant. Use a small spoon or your fingers to dig a hole, place the plant inside, and gently backfill with soil, patting it down to secure the plant.
Once your plants are in place, you can add a decorative top dressing. This isn’t just for looks; it also helps keep the leaves from touching wet soil. Fine gravel, decorative sand, or small river stones work beautifully. Now, stand back and admire your work!
The Ultimate Succulent Terrarium Care Guide
You’ve built your masterpiece. Now what? Following these growing succulents in terrarium best practices is the key to keeping it looking great for years. This is your essential growing succulents in terrarium care guide.
The Art of “Just Enough” Light
Succulents need a lot of bright, indirect light. A spot near an east-facing window is often perfect, providing gentle morning sun. A south or west-facing window can also work, but you may need to pull the terrarium back a bit to avoid scorching the leaves with intense afternoon sun.
If you don’t have enough natural light (a common issue for us apartment-dwelling aquarists!), don’t worry. A simple full-spectrum LED desk lamp or a small grow light set on a timer for 10-12 hours a day works wonders.
Watering: The Number One Mistake to Avoid
Overwatering is the number one killer of succulents. Because your terrarium has no drainage, you must be extremely careful. The golden rule is: when in doubt, don’t water.
Wait until the soil is completely bone dry all the way through. You can check with a wooden skewer—if it comes out with any damp soil on it, wait longer. When it’s time to water, use a small watering can with a narrow spout or even a syringe to direct a small amount of water to the base of each plant. You want to moisten the soil, not saturate it. For a small terrarium, this might only be a few tablespoons of water every 2-4 weeks, depending on your home’s climate.
Airflow and Temperature
Remember, your succulents love good airflow. The open top of your terrarium helps, but avoid placing it in a stuffy, humid room (like a bathroom without a fan). Average room temperatures are perfectly fine for these hardy plants.
Troubleshooting Common Problems with Growing Succulents in Terrarium
Even with the best care, you might run into an issue. Don’t panic! Here are some fixes for the most common problems with growing succulents in terrarium setups.
Help! My Succulents are Stretched Out (Etiolation)
If your plants are getting tall, pale, and “leggy,” with lots of space between the leaves, it’s a classic sign they aren’t getting enough light. This is called etiolation. The solution is simple: move your terrarium to a brighter spot or supplement with a grow light. You can’t reverse the stretching, but you can prune the stretched parts and new, more compact growth will appear in the right light.
Dealing with Rot and Mushy Leaves
This is almost always a sign of overwatering. If you see yellowing, translucent, or mushy leaves, especially near the base of the plant, you’ve been too generous with the water. Immediately stop watering. If you can, gently remove the affected plant, trim any black or mushy roots, let it dry out for a day, and then replant it in dry soil. Moving forward, drastically reduce your watering frequency.
Pesky Intruders: Gnats and Mealybugs
Fungus gnats are tiny black flies that are attracted to damp soil. Their presence is another sign you might be overwatering. Letting the soil dry out completely between waterings is the best way to eliminate them. For mealybugs (small, white, fuzzy pests), you can dip a cotton swab in 70% isopropyl alcohol and touch it directly to the pests to remove them.
Creating a Sustainable and Eco-Friendly Succulent Terrarium
One of the best parts of this hobby is how it connects us to nature. You can easily extend this to sustainable growing succulents in terrarium practices.
Think about eco-friendly growing succulents in terrarium options. Repurpose an old glass jar, a vase, or even a chipped cookie jar that can no longer be used for food. Look for locally grown succulents at a farmers market to reduce shipping impact. Best of all, succulents are incredibly easy to propagate. A single leaf or a cutting from an existing plant can be rooted to grow a whole new one—a perfect, sustainable way to expand your collection or share with friends!
Frequently Asked Questions About Growing Succulents in Terrariums
Can I use a closed terrarium for succulents?
Absolutely not. This is the most critical rule. A closed terrarium creates a humid, moist environment that will quickly cause succulents to rot. Always use an open container with good airflow.
How often should I *really* water my succulent terrarium?
This depends entirely on your environment, but much less than you think. A good starting point is every 2-4 weeks. The key is to only water when the soil is 100% dry. Always err on the side of underwatering.
Do I need to fertilize my terrarium succulents?
Very rarely. Succulents are adapted to nutrient-poor soil. You can feed them with a heavily diluted cactus fertilizer once a year in the spring, but it’s often not necessary. Over-fertilizing can harm them.
What are the easiest succulents for beginners to start with?
Great question! For beginners, I highly recommend Haworthia and Gasteria species. They are incredibly tough, forgiving of watering mistakes, and tolerate slightly lower light conditions than many other succulents, making them perfect for indoor terrariums.
Your Miniature World Awaits
There you have it—everything you need to know for success. We’ve covered the crucial open-container rule, the proper layering technique, and the all-important watering discipline. Remember these key growing succulents in terrarium tips, and you’ll create a beautiful, thriving miniature garden.
