About this guide
A garden under glass.
A closed terrarium brings the details of a miniature landscape into view: a fern unfolding, a patterned leaf and the changing appearance of moisture on glass. The Closed Terrarium introduces the choices behind creating that small living environment.
Explore suitable containers, humidity-loving plants and the materials needed for a first project. Follow a planned assembly sequence, then learn what to observe as the planting settles in. Chapters on light, moisture and routine care help you move beyond the idea that a sealed garden can simply be forgotten.
Designed for beginners, this guide combines practical explanations with project notes and observation prompts. It encourages you to choose plants with compatible needs and adapt your care to the conditions you actually see. A beautiful composition is the beginning of an ongoing gardening project.

What it will not do
No guarantees about plants
No plant is impossible to kill, no composition is maintenance-free and no project works in any room. The guide gives no universal watering calendar, no pesticide recipes and no diagnosis from appearance alone, and it makes no claims about purifying the air.
