People think of Australia when they hear talk of growing eucalyptus trees. It is the food of the koala bear and lives through the dramatic fires that sweep that country's landscape. People have cultivated the fragrant tree in southern temperate areas that reach across the continent where frost is not a problem. Growers have found that propagating the trees can be a challenge, even when using cuttings.
Cut down the eucalyptus tree that you wish to clone. This might seem drastic, but it has proven to be a very successful way of getting the cuttings to grow.
Cut the sprouts off where they intersect the tree once they have a couple of leaves. You will use the coppice sprouts that spring up around the trunk for the cuttings.
Dip the end of the cutting into a powdered rooting hormone designed for use with trees. Place it directly into a container filled with rooting medium consisting of vermiculite, pine bark, and perlite. The mixture needs to be able to retain water without hindering drainage. Nurseries use long thin containers or tubes.
Move the containers with the cuttings into a closed and warm (75 degrees Fahrenheit) environment where they can get plenty of humidity, such as in a misted greenhouse, a tented plastic covering, or a larger plastic container with a lid to hold in moisture. Keep them in a shaded spot for 45 days. You can expect about a 75 percent success rate if your circumstances are near perfect.
Move the cuttings out to an area where they can get partial sunlight. Remove any covering that have been over them and keep them in the partial light for another 10 to 15 days. This will help acclimate them to the light and speed up the growing process.
Move the cuttings to full sunlight. They will remain here for the next month when they should be ready for planting into their permanent home.
