Terrarium Container Options & Selection Criteria

Whether you're new to indoor gardening or a seasoned plant lover, building a diy terrarium is a creative, budget-friendly way to bring a slice of nature into any space. The right container sets the stage for a thriving mini-ecosystem. Below, explore container types, how to match them to your plants and space, and budget-friendly options.

Understanding terrarium container types

• Glass jars (mason jars, apothecary jars)

• Pros: inexpensive, airtight for closed terrariums, clear walls showcase layers

• Cons: limited airflow in closed designs, narrow openings can complicate planting and maintenance

• Fish bowls & bell jars

• Pros: wide mouth for easy access, dramatic dome shape enhances visual impact

• Cons: bulky, heavier substrate needed for stability, less suited for hanging

• Hanging glass orbs

• Pros: space-saving, modern aesthetic, perfect for air plants or minimal soil setups

• Cons: shallow depth restricts root growth, fragile construction

• Repurposed vessels (teapots, lightbulbs, vintage jars)

• Pros: sustainable, one-of-a-kind character, often free or low cost

• Cons: variable durability, may require extra cleaning or sealing

For larger or custom designs, consider small fish tanks or acrylic display boxes. Their straight sides and lids make them ideal for complex DIY succulent terrariums or tropical scenes.

Matching containers to plant needs and display space

• Closed vs. open design

• Closed (airtight) suits moisture-loving tropicals (e.g., ferns, Fittonia)

• Open terrariums favor succulents, cacti, and air plants that need good airflow

• Size and shape

• Tall, narrow vessels work well for upright ferns or trailing stems

• Wide, shallow bowls are perfect for sprawling succulents or layered sand art

• Location and lighting

• Small desktop jars fit offices or side tables

• Hanging orbs brighten windowsills and corner spaces

Budget considerations: repurposed vs. store-bought vessels

• Repurposed options

• Thrift-store glassware, old kitchen jars, or discarded lightbulbs—often under \$5

• Cleaning: wash with warm soapy water, soak in a 10% bleach solution, rinse and air dry

• Store-bought vessels

• Craft-store bell jars: \$15–\$30

• Specialized terrarium kits (glass vessel included): \$20–\$50

Pro tip: dollar-store glass containers, properly cleaned and sealed, can rival pricier options.

Once you’ve selected the perfect container, it’s time to choose plants that will bring your diy terrarium to life.

Ideal Plants & Pairing Recommendations

Best low maintenance plants for terrariums

• Succulents (Echeveria, Haworthia)
  Light: bright, indirect light
  Water: minimal, allow soil to dry between waterings

• Air plants (Tillandsia)
  Soil: none needed
  Water: mist 1–2 times weekly or soak for 20 minutes monthly

• Mosses (sheet moss, cushion moss)
  Humidity: thrives in closed systems
  Role: ground cover, humidity regulation

Closed vs. open terrariums: plant compatibility

Closed terrariums recreate a rainforest-like microclimate. Choose moisture-loving species:

• Peperomia varieties (Peperomia obtusifolia, Peperomia caperata)
• Fittonia (nerve plant)
• Ferns (button fern, maidenhair fern)
• Sphagnum moss

Avoid succulents and cacti in closed designs—they’re prone to rot in high humidity.

Open terrariums need plants that prefer drier conditions:

• Succulents and cacti
• Air plants
• Small terrestrial orchids

Creating balanced ecosystems: succulents, ferns, air plants

• Mixing zones: use raised soil “islands” for succulents, lower pockets for ferns
• Vertical layers: suspend air plants on driftwood or wire hooks above soil
• Spacing: leave 1–2 inches between plant crowns to prevent overcrowding and ensure airflow

With your plant palette set, let’s assemble your diy terrarium step by step.

Step-by-Step DIY Terrarium Assembly & Layering Process

How to make a terrarium step by step: building from scratch

1. Clean and dry your container completely.
2. Add a 1–2 inch drainage layer of pebbles or aquarium gravel.
3. Sprinkle a ¼–½ inch layer of activated charcoal to keep water fresh and control odors.
4. Place a thin sheet of sphagnum moss over the charcoal to prevent soil from filtering down.
5. Add potting mix: use cactus/succulent mix for open terrariums or all-purpose mix amended with peat for closed designs.
6. Arrange plants with long tweezers or chopsticks: dig small holes, insert root balls, and gently firm the soil around them.
7. Top-dress with decorative sand, gravel, or moss; label plant varieties if desired.

Substrate layering: drainage stones, activated charcoal, soil

• Drainage stones: essential to prevent root waterlogging
• Activated charcoal: reduces bacterial growth and odors (RHS recommends charcoal for enclosed environments)
• Sphagnum moss barrier: stops soil from mixing with drainage material
• Potting mix:
• Succulent mix for open terrariums
• Peat-amended mix for closed systems

Planting and top-dressing techniques

• Use specialized tools (tweezers, chopsticks) to position small plants precisely
• Make planting pits slightly larger than root balls to avoid compaction
• Firm soil gently to support roots while preserving aeration
• Add contrasting textures with colored sand, polished stones, or sheet moss

Addressing common assembly mistakes

• Skipping the charcoal layer → risk of stagnant water and mold
• Overcrowding plants → limited growth and poor airflow
• Using garden soil → compaction, pests, and drainage issues
• Neglecting to clean the container → algae and mold buildup

Pro tip: leave at least 1 inch of headspace below the lid for air circulation in closed terrariums.

Maintenance & Humidity Control

How often to water a DIY terrarium

• Closed terrariums: water sparingly—every 4–6 weeks or when condensation subsides
• Open terrariums: mist foliage weekly or water lightly every 1–2 weeks, adjusting for plant type and ambient humidity
• Signs:
• Dry soil surface or wilting leaves → time to water
• Yellowing leaves → often indicates overwatering

Closed vs. open design: humidity control strategies

• Closed: relies on a natural moisture cycle—occasional lid cracks help prevent mold
• Open: regular misting, pebble trays, or proximity to a humidifier maintain moisture levels

Monitoring plant health and making adjustments

• Inspect weekly for yellowing, wilting, or mold spots
• Rotate your terrarium monthly to ensure even light exposure
• For precision, use a hygrometer in premium kits to track humidity (internal “Terrarium Care 101” guide)

Styling & Decorative Accents

Infusing personality with stones, figurines, moss, colored sand

• River rocks and polished pebbles for miniature pathways
• Mini figurines (fairies, animals) to tell a story
• Sheet moss for vivid green highlights
• Layered colored sand for desert-style terrarium ideas

Terrarium ideas: themes and design inspiration

• Beach: white sand layers, seashells, air plants
• Desert: gravel, succulents, driftwood
• Forest: bark chips, ferns, miniature mushrooms
• Fairy garden: moss, tiny houses, pastel figurines

Seasonal refresh and redecoration tips

• Add tiny pumpkins or gourds for autumn
• Swap in miniature ornaments and red-green moss for holidays
• Prune and rotate plants to maintain a fresh look each season

Troubleshooting Common Terrarium Problems

Dealing with mold and algae growth

• Ensure a proper drainage layer and activated charcoal filter
• Avoid overwatering; siphon out excess water immediately
• Increase ventilation by removing the lid for a few hours daily
• According to the Royal Horticultural Society, activated charcoal reduces microbial growth

Addressing wilting or rotting plants

• Identify root rot: mushy stems, blackened roots
• Trim affected roots and foliage; repot healthy parts in fresh, dry substrate
• Adjust watering frequency—allow the top layer of soil to dry completely

Pest prevention and control

• Introduce beneficial springtails or isopods to consume mold and decaying matter
• Apply neem oil or insecticidal soap sparingly on open terrariums
• Quarantine new plants for 1–2 weeks before introducing them to your terrarium

With these comprehensive tips, your diy terrarium will thrive, delight, and inspire—no matter your budget or experience level. Enjoy your personal window into nature's wonders!
