Open terrarium care
Caring for an open terrarium is simple, as long as you match the care routine to the plant types inside.
- Succulents & cacti: water every two weeks, only when the soil is bone dry. These plants prefer drier conditions and well-draining soil.
- Tropical plants:keep the soil slightly moist. Water 1–2 times a week, but avoid overwatering.
- Moss: thrives with consistent humidity. If it dries out, soak it in water for 10–15 minutes, gently squeeze out the excess, and place it back.
Where to place an open terrarium
Proper placement is key to a thriving open terrarium. Choose a location with bright, indirect light, like near a window with sheer curtains or on a well-lit shelf. Avoid direct sunlight, which can overheat or scorch your plants.
Keep your terrarium away from radiators, heaters, or cold drafts. Ideal room temperature ranges between 15°C and 25°C. Stability is important: terrariums don’t like to be moved too often. Once it’s placed, let the micro-environment adjust naturally.
