Some Helpful Tips

  • Terrariums thrive in indirect bright light.
  • When condensation builds up on the glass, it is a sign that it’s time to open it up and let some air in.
  • How much water your terrarium needs depends on how much condensation builds up and how often you aerate. As a general rule of thumb, water once a week. But, remember, it is always easier to add more water than to remove the excess. A terrarium should never be soggy.
  • To transplant from your terrarium, make sure the soil is moist in the container you’re transplanting from. Use a spoon to try to dig out a small root ball of soil about an inch in diameter to minimize the root disturbance. Place your plant in a new container and water thoroughly.
