Most terrarium guides start with soil and plants. This one starts with a question you should answer first: what kind of scene are you actually trying to build?
Before you buy a single pebble, it helps to pick a style. The style decides your container shape, your substrate, your plant list, and how much water the whole thing will need — which is why skipping this step is the reason so many first terrariums end up looking like a jar of dirt with a leaf in it. Below are the four styles that cover almost every terrarium you’ll see, what makes each one work, and how to build it without mixing incompatible elements.
If you haven’t built a terrarium before, it’s worth reading our mini terrarium step-by-step guide alongside this one — that post covers the mechanics of layering, and this one covers the design decisions that sit on top of those mechanics.
1. Desert Style
Desert terrariums are the easiest style to get wrong by overwatering, because everything about them — sand-colored substrate, wide-open containers, spiky silhouettes — signals “low maintenance,” which is true only if the drainage and light are correct.
What defines it: an open (not sealed) container, a thick mineral drainage layer, gritty fast-draining substrate, and sun-loving succulents or small cacti as the focal plants. Rock and sand do the visual work instead of moss or foliage.
How to build it:
- Use an open dish or bowl, never a sealed jar — trapped humidity rots succulents fast.
- Layer drainage rocks or lava rock generously at the base, then a fast-draining mix like our succulent terrarium soil guide recommends.
- Group plants by height instead of spacing them evenly — a tall echeveria or small cactus as a focal point, low-growing haworthia or sedum filling the rest.
- Finish with sand, fine gravel, or decorative stones rather than moss.
Succulents need considerably more direct light than tropical terrarium plants — Iowa State University Extension notes that most succulents grown indoors need at least six to eight hours of bright light a day, more than a shaded shelf can usually provide (source). A south- or west-facing windowsill is the deciding factor for whether this style survives past month one.
2. Zen / Japanese Style
Where desert style is about texture and light, zen style is about restraint. The goal isn’t a lot of plants — it’s negative space, asymmetry, and a sense of stillness.
What defines it: muted color palette, a single dominant material (usually stone or moss), deliberate empty space, and one or two focal elements rather than a full plant collection. Think of it as a terrarium built the way a rock garden is built.
How to build it:
- Choose a low, wide, open container — height competes with the “flat landscape” feel this style relies on.
- Moss carries most of the visual weight. Cushion moss works well as a dense, sculptural mound; our guide to choosing moss for mini terrariums breaks down which types hold shape versus which spread flat.
- Add one or two smooth stones as a focal point rather than scattering decorative gravel throughout — in this style, fewer, more deliberate elements read as more expensive and more calming.
- Rake or smooth the substrate around the stones the way you would a miniature zen garden, and resist the urge to add more plants once it looks “finished.”
3. Fairy Garden Style
This is the style most people picture when they hear “terrarium” for the first time — small figurines, tiny paths, and a sense of a miniature world rather than a plant display.
What defines it: whimsical scale, a narrative (a path leading somewhere, a tiny door, a bridge), and plants chosen for how small and slow-growing they stay, not for how showy they are.
How to build it:
- Pick a container with a wide opening — fairy garden scenes need room to arrange props, and a narrow neck makes placement nearly impossible.
- Start with the hardscape story first (path, structure, water feature), then plant around it, not the other way around.
- A curated terrarium plant bundle is the fastest way to get several appropriately tiny, slow-growing plants without guessing at compatibility.
- Keep a basic terrarium tool kit on hand — placing small figurines and trimming around them by hand is much easier with long tweezers than with your fingers.
Because this style relies on small props more than a specific plant type, it’s also the most forgiving for beginners in our category of mini terrarium guides — most mini terrarium builds can be adapted into a fairy garden with a few added props.
4. Rainforest / Tropical Style
This is the style closest to a true miniature ecosystem: a closed, humid, layered terrarium meant to visually — and functionally — mimic a forest floor.
What defines it: a sealed container, high humidity, dense layered planting (tall background plants, mid-height foliage, moss or creeping groundcover), and genuine self-watering through condensation.
How to build it:
- Use a sealed jar, cloche, or bottle so humidity can build and cycle — this style depends on the closed-terrarium water cycle rather than manual watering.
- Layer substrate built for closed, tropical setups — regular potting soil alone won’t drain well enough in a sealed container.
- Build in visual layers: taller plants toward the back or center, low foliage and moss filling the foreground, similar to how a real forest floor is structured.
- Browse our full terrarium plants category for humidity-loving species, and if you want to extend the concept into a water feature, our aquatic plants category covers species like Anubias barteri nana that work well at the edge of a paludarium-style build.
The closed terrarium itself has a genuinely interesting backstory: the format was invented almost by accident in 1842 by botanist Nathaniel Bagshaw Ward, who noticed a fern spore sprouting in a sealed glass case he’d forgotten about — the same water-cycle principle rainforest-style terrariums use today (source).
Which Style Should You Start With?
If you’re building your first terrarium, fairy garden and desert styles are the most forgiving — fewer humidity requirements to get wrong. Zen and rainforest styles ask more of you upfront (moss sourcing, sealed-container balance) but reward patience with something that looks noticeably more intentional.
Whichever style you pick, the fundamentals don’t change: right container, right substrate, right light. If you haven’t nailed those basics yet, start with our mini terrarium step-by-step guide, then come back and pick a style to build toward.
