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.
1 Make each cut with sharp shears and at a 45 degree angle.  Ideally, you should still try to cut the plant down to a bud. If you cannot find a bud that is low enough, however, the shrub should still be able to produce a new bud below the cut once the growing season starts again.
