Never made a terrarium? Start here.

• The jarA sealed jar waters itself: plants breathe water out, it beads on the glass and runs back down.
• LayersBottom to top: drainage, a barrier, soil, then a top dressing.
• PlantsSmall, slow and alike in what they want.
• MossNo roots: moss drinks from the air and the surface it sits on.
• Cleanup crewTiny animals that keep a jar from rotting.
