What is a Terrarium? Definition of a Terrarium

A terrarium is a small garden arrangement typically created within glass containers, providing suitable conditions for plant growth. These miniature gardens can be closed systems that retain humidity or open designs that allow air circulation. Closed terrariums create a self-sustaining ecosystem by trapping humidity and heat inside. In contrast, open terrariums are better suited for plants that require more airflow. Terrariums are used not only for decorative purposes but also to observe plant growth processes and simplify plant care. They save space in small living areas while bringing nature into your home.

Types of Terrariums: Closed and Open Terrariums

Terrariums are divided into two main types: closed and open. Each type has unique advantages and is suitable for different plant needs.

Closed Terrarium
Closed terrariums maintain humidity and temperature within a glass container, creating a microclimate. Plants that thrive in humid environments, such as ferns, fittonias, and mosses, are ideal for this type. Due to their closed nature, watering needs are minimal as the moisture cycle is continuous inside the terrarium.

Open Terrarium
Open terrariums are suitable for plants that require more air circulation, such as succulents and cacti. Regular watering and direct sunlight are essential for the healthy growth of plants in open terrariums.

Both closed and open terrariums offer aesthetic appeal. When choosing between them, consider the needs of your plants and ease of maintenance. Creating a terrarium at home is simple by following a few basic steps.

Steps for Making a Terrarium

Container Selection
Choose a glass jar, bowl, or terrarium case. For a closed terrarium, use a container with a lid; for an open terrarium, opt for one with a wide opening.

Base Preparation
Start by placing pebbles or small stones at the bottom to ensure proper drainage. Add a layer of activated charcoal on top to prevent odors and harmful substances.

Add Soil
Prepare a soil mix suitable for your plants. Use sandy, well-draining soil for succulents and cacti.

Placing the Plants
Select plants such as succulents, cacti, fittonias, or ferns for your terrarium. Carefully place the plants in the soil, ensuring their roots are fully covered.

Decoration
Decorate your terrarium with pebbles, moss, miniature figurines, or natural objects. This step allows you to personalize your terrarium.

Watering and Maintenance
After creating the terrarium, water the plants according to their needs. Closed terrariums naturally retain moisture, so watering frequency should be minimal.

Which Plants Are Suitable for Terrariums?

When selecting plants for a terrarium, consider their requirements for humidity, light, and temperature. Here are some ideal plants for terrariums:

Cacti and Succulents
These low-water plants thrive in sunny conditions and are perfect for open terrariums. Their varied shapes and colors add a decorative touch to your terrarium.

Fittonias
These humidity-loving plants are excellent for closed terrariums. Their vibrant leaves bring life to the arrangement.

Ferns and Mosses
These plants thrive in high-humidity environments and grow well in closed terrariums. They provide a natural look with various shades of green.

These terrarium plants enhance your arrangement with their durability and aesthetic appeal.

Terrarium Care: Tips for Healthy Plants

Terrarium care is essential for the healthy growth of plants. Here are the key points to consider:

Watering
In closed terrariums, watering frequency is very low due to the natural moisture cycle. Open terrariums may require weekly watering, depending on the plant type. Avoid overwatering, as it can cause root rot.

Light
Terrariums should be placed in bright areas without direct sunlight. Open terrariums with sun-loving plants like succulents and cacti can be positioned near a window.

Humidity and Air Circulation
For closed terrariums, occasionally opening the lid to allow air circulation helps prevent excessive humidity and keeps the plants healthy.

A terrarium is a miniature ecosystem that brings nature into your home. Creating a terrarium at home is simple with the right materials and plant selection. Terrarium types, whether open or closed, offer different advantages depending on plant needs.

By providing regular care, you can preserve the beauty of your terrarium for a long time. Terrariums create a decorative and calming environment, making them an excellent choice for those new to plant care.
