How to make a terrarium? Best tips

Larger terrariums can accommodate somewhat larger houseplants, but avoid fast-growing species or those with large leaves that may block the light needed by smaller plants. When considering plants for terrariums, look for plants that grow well in low to medium light. To make them more attractive, choose a mix of leaf sizes, textures, and colors. Here, we tell you how to make a terrarium.

Select plants that are not bothered by the naturally humid environment of a terrarium. Avoid cacti and succulents in closed terrariums; these plants work best in open containers filled with a potting mix with plenty of coarse sand.

What do I need to make a terrarium?

To make a terrarium, you will need a glass container with a lid, small stones or pebbles, activated charcoal, potting soil, plants, and optional decorative elements.

What is the difference between a terrarium and a vivarium?

A terrarium and a vivarium are similar in concept but differ in the types of organisms they house. A terrarium is specifically designed to accommodate plants and create a miniature garden environment. It typically contains a variety of plants and sometimes decorative elements.

On the other hand, a vivarium is an enclosed space designed to house and sustain the life of various animals, such as reptiles, amphibians, or insects. It usually includes elements such as heat lamps, burrowing substrate, hiding places and specialized lighting to meet the specific needs of the plants.

What do terrariums need to survive?

Terrariums primarily need indirect sunlight, adequate watering (avoid watering to saturation or allowing them to dry out completely), and a well-drained soil mix. The enclosed or partially enclosed environment of a terrarium creates a self-sustaining ecosystem by recycling moisture and nutrients, which reduces the need for frequent watering.

How do you make a simple terrarium?

Making a terrarium is a fun and rewarding project. Here’s a step-by-step explanation of how to make a simple terrarium:

Materials:

• Glass container with a lid (such as a jar, fishbowl, or vase).
• Small stones or pebbles.
• Activated charcoal (available at pet stores or garden centers).
• Soil suitable for plants.
• Assorted small plants (succulents, mosses, or air plants).
• Decorative elements (optional).

Clean the container

Wash the glass container thoroughly with warm, soapy water to remove any dirt or debris. Dry thoroughly before proceeding.

Add drainage

Place a layer of small stones or pebbles in the bottom of the container. This will create a drainage layer, preventing water from pooling and causing root rot.

Add activated charcoal

Sprinkle a thin layer of activated charcoal over the stones. Activated charcoal helps absorb excess moisture and keeps the terrarium cool.

Add potting soil

Add a layer of potting soil on top of the charcoal layer. The depth should be sufficient for plant roots to become established. Make sure the soil is level and smooth.

Plant the terrarium

Dig small holes in the soil to place your chosen plants. Carefully remove the plants from their pots, loosen the roots, and place them in the holes. Surround the plants with soil to secure them.

Place decorative elements

If you wish, you can add decorative elements such as figurines, rocks, or driftwood to enhance the visual appeal of your terrarium. Be careful not to overcrowd the space, as plants need room to grow.

Spray and close the lid

Lightly mist the soil and plants with a spray bottle. This will provide initial moisture. Then close the terrarium lid to create a moist environment for the plants.

Find the right location

Place the terrarium in a location that receives indirect sunlight. Avoid placing it in direct sunlight, as it may overheat and damage the plants. Terrariums can thrive in a variety of indoor environments, such as offices, living rooms, or bedrooms.

Terrarium maintenance

Monitor your terrarium regularly and adjust watering according to humidity levels. If you notice excessive condensation or a musty odor, open the lid for a while to circulate fresh air. Cut back any overgrown or decaying plants to maintain the health and aesthetics of the terrarium.

Now that you know how to make a terrarium you can tell us your experience or recommendations with them.
