Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.
How to Take a Eucalyptus Cutting. Juvenile eucalyptus trees root better than adult trees. Eucalyptus (Eucalyptus spp.), are ornamental trees, that often grow to heights of 80 to 120 feet. Native to Australia, eucalyptus grow in the warmer climates of U.S. Department of Agriculture plant hardiness zones 6 through 11, depending upon the species. They're easy to propagate from seed, but you can also clone them through rooted cuttings taken from juvenile trees.
For a rough estimate, use the diameter of the tree's trunk in centimeters. The number is an approximation of the years the tree has been alive. For example, a eucalyptus with a diameter of 30 centimeters at breast height is approximately 30 years old.. Measure from the base of the eucalyptus trunk up to 54 inches. Mark the level on the tree with a piece of masking tape. This is considered breast height.
