One of the most exciting ways to reinvent an object is to fill it with life. Whether it’s that old jar that’s been sitting around, or that cool cloche you bought and are wondering what to do with, it can be transformed into a miniature landscape in a few simple steps. Below you’ll find a guide to building up the layers of a terrarium, from the soil base to the plants. Don’t be afraid to experiment with different containers, plants, and found objects.
TERRARIUM BUILDING TIPS
• If the container you choose is open, use plants that like lower humidity like cacti and succulents. These plants will need a bit more sunlight, but avoid direct sunlight, as the terrarium glass can act as a magnifying glass and burn the plants.
• If the container you choose has a small opening or a lid, use plants that like higher humidity like ferns and mosses. We find that a container with a removable lid like a cork or jar lid is a good option because you can regulate the humidity level inside as needed.
• Provide more soil when using ferns and leafy house plants. You may want to mix in some sand for cacti and succulents.
• Use a container with a wide opening for easy planting. If planting a container with a narrow neck, long-handled tweezers or other long-handled tools may help in planting.
WATER
Most open terrariums will need to be watered at least once a week, while closed terrariums,
if well sealed, may never require watering after the initial planting, watering and closure.
LIGHT
Most terrarium plants (especially in closed terrariums) will do best in indirect light.
HUMIDITY
Use a mister or spray bottle to create humidity in an open or partially open terrarium.
CLEANING & PRUNING
Most terrarium plants won’t require much maintenance, but over time you might need to clean out any dead plant material and trim any plants that are getting too large. This will help keep all your plants happy and healthy.
