Terrariums are charming and low-maintenance ecosystems that can bring a touch of nature into your home or office. Whether you have a green thumb or not, creating a basic terrarium is a rewarding and straightforward DIY project. In this guide, we’ll walk you through the process of making a basic terrarium, step by step, and provide tips along the way.
What is a Terrarium?
Terrariums are miniature ecosystems enclosed in glass containers. They mimic natural environments, allowing plants to thrive with minimal care. A typical glass terrarium consists of the following components:
- Glass Container: Choose a clear glass container, or a jar for a jar terrarium, depending on your preference and the type of terrarium you want to create.
- Gravel or Small Rocks: This layer at the bottom provides drainage to prevent root rot.
- Activated Charcoal: A thin layer of charcoal helps absorb odours and keeps the terrarium fresh.
- Potting Mix: The growing medium for your plants.
- Small Plants: Select plants suitable for your terrarium type, such as succulents, air plants, or tropical varieties.
- Decorative Elements: Optional additions like miniature figurines, stones, or coloured sand can enhance the visual appeal.

Different Types of Terrariums
Terrariums come in various types to suit different plant preferences and environments:
- Open vs. Closed: Open terrariums are low-maintenance and suitable for plants that prefer drier conditions, while closed terrariums are ideal for tropical plants as they create a self-sustaining microclimate.
- Desert vs. Tropical: Desert terrariums house succulents and cacti, while tropical terrariums host moisture-loving plants.
- Succulent vs. Moss: Succulent terrariums feature drought-tolerant plants, while moss terrariums are lush and green, perfect for shaded areas.
