Terrariums – Gardens within Glass

Imagine a miniature garden in a crystal ball or a glass jar: a glass-enclosed oasis of a woodland scene, or a tropical garden, or an orchid garden. Living plants will reside in the landscapes that you create, could be little hills amongst rocks, lichen, or even sea shells, or it could be a water world.

How Terrariums Work

Closed Terrariums don’t need to be watered much; they trap water inside. When the water evaporates, it condenses against the sides of the terrarium and falls down again. Terrarium plants can go for weeks, even months, without being watered.

Most terrarium are best placed in indirect sunlight. Direct sunlight can overheat and harm the plants. Only desert terrariums should be placed directly in the sunlight. A well-placed and nicely set-up terrarium thrives with little maintenance and adds beauty to any setting.

Between the tropical and temperate zones of the world are Earth’s sub tropical forests. Sub tropical plants have unique characteristics, making them well suited for terrariums. They can withstand a range of temperatures, from tropical temperatures to frosts that would destroy most tropical plants.

Many small sub tropical plants are hardy and ideally suited for terrariums

Among them are:

The best temperature for a sub tropical terrarium is 16 °C – 21 °C (60 °F to 70 °F), minimum 7 – 13 °C (45-55 °F), maximum 24 – 29 °C (75- 85 °F).

A List of the Materials Needed to Construct Terrariums, those Wonderful Gardens in Glass Containers

  • Transparent Terrarium Container: Terrariums can be made with glass or plastic jars. Or with fish bowls, aquarium tanks, or other transparent vessels. Even soda bottles! The container must be transparent and not tinted, so it lets enough sun in.
  • Drainage Material
  • Gravel, or pebbles, or glass beads, or Terra-lite. This is for the drainage layer, which absorbs excess water. Drainage is essential for maintaining plant health. If the soil becomes saturated with water, it can become a medium for fungi or harmful bacteria that rots the roots.
  • Activated Charcoal: Activated charcoal help terrariums fresh by absorbing gases and chemicals that could otherwise harm plants. Beware that you should NOT use barbecue charcoal since it usually contains chemicals that can harm plants.Funnel: A plastic funnel with an adequately wide opening or a one made with sturdy paper or some other material. Using a funnel to pour materials into terrarium containers helps keep the terrarium walls clean.
  • Mesh Or Screen: The mesh prevents soil from shifting into drainage layers below. Many materials, cut to size can serve this function -sphagnum moss, or muslin, or cheesecloth, or nylon screen, or gauze, or landscape fabric, or fiberglass drapery fabric, or sheer drapery, or even pantyhose, or some other improvised material.Activated charcoal
  • Terrarium Soils: Standard potting mix usually is fine for terrariums but some kinds of terrariums may require particular soil mixes. Other pages of this site go into further detail of the appropriate soils for terrariums.
