Eucalypts are evergreen trees and shrubs that are native to Australia. There are well over 600 different varieties of eucalyptus. According to Sunset Plant Finder, eucalypts are the most commonly planted non-indigenous trees in California and Arizona. Eucalypts are revered for their fast growth, beauty, hardiness and their adaptability to a wide variety of climates. Plant a eucalyptus in full sun, and choose a planting location conducive to the variety of eucalyptus you are growing.
Dig a hole that is twice the width of the root ball of your eucalyptus and about the same depth. If you're planting a eucalyptus near your house, make sure to keep it spaced at least 10 to 16 feet away from the house for small varieties, and at least 16 to 25 feet away for larger varieties.
Cut or snip off the encasing around the root system of the eucalyptus plant, if the encasing is of synthetic material. If the encasing is of organic material (such as burlap), there is no need to entirely remove it at this point. Use care not to sever or damage the roots when removing the encasing. Set the eucalyptus into the previously dug hole
Check to make sure the top of the root system of your eucalyptus is sitting above the level of the surrounding garden soil. It should be sitting about 1 1/2 to 2 inches higher. Add or remove soil under the root ball until you are sure the eucalyptus is sitting at the correct height. Scoop in garden soil slowly around the root system until the hole is about 1/2 full. If the root system is encased in burlap, now is the time to cut back the burlap to about halfway down the root system.
Place a tall (6- to 8-foot) planting stake alongside the root ball. Make sure it's firmly set into the soil. (This is helpful to ensure the eucalyptus will grow straight). Check to make sure the eucalyptus plant is sitting straight and level in the hole. Scoop soil into the hole until it's full, firming it down with your hands or a stick.
Create a 3- to 4-inch-high circular moat of dirt around your eucalyptus (this will help when watering, allowing a pool of water to accumulate, which will let water soak down to reach the roots). Water your eucalyptus generously. Gently tie the eucalyptus plant to the planting stake using string or planting twine.
