From the page: The glass jar still has plenty of stories left in it
Idea 1
Sealed terrarium
Sealed terrariums were born in 1829, when the botanist Nathaniel Ward noticed that plants could survive inside sealed glass vessels. It works because the jar creates a mini cycle: the plant transpires, the water condenses on the glass, and returns to the soil, watering itself.
What you need
- Glass jar with a lid (canning, olive, or granola jars)
- Small pebbles or gravel for drainage
- Activated charcoal (from an aquarium or filter) to prevent mold
- Light potting mix (soil with a bit of sand)
- Small shade-loving plants: peperomia, fittonia, moss, or a mini fern
- Long-handled spoon or tweezers for planting without getting the glass dirty
- Spray bottle with water
How to make it
-
1
Wash the jar thoroughly and dry it. Clean glass ensures visibility and prevents fungal contamination from the very start.
-
2
Build the base layer: 3 to 4 fingers' worth of pebbles at the bottom, so extra water collects away from the roots — this drainage is what prevents rotting.
-
3
Sprinkle a thin teaspoon of activated charcoal over the stones. It absorbs odors and substances that encourage mold in a sealed environment.
-
4
Add the potting mix, forming a slight depression in the center where the cutting's roots will settle with more stability.
-
5
Plant using the tweezers or spoon, arranging the roots and firming the soil around them. Mist water slowly — moist soil, not soaked.
-
6
Close the lid and observe over the first few days: if the glass fogs up constantly, leave it open for a few hours. Light, momentary condensation is a sign of a healthy cycle.
Finishing touches
keep the terrarium near bright light but out of direct sun, which cooks the sealed environment. If you want extra charm, cover the soil with dried moss and one larger decorative pebble.
