Light: Eucalyptus likes a lot of light, so settle your plant somewhere that receives at least six hours of direct sunlight daily. Likewise, eucalyptus plants grown indoors should be kept near a bright window, preferably one that faces south.
Water: somewhat drought tolerant. However, it really doesn't like to be left dry for long periods, and doing so might cause it to drop leaves or branches.
Temperature: prefers temperatures between roughly 18-23 degrees Celcius, and it likes a moderate humidity level.
