Question
We have a 6' Norfolk pine.  Is there anyway to start a new tree from a branch or the top part of the tree, etc.?

Answer
Take 6-8 in (15.2-20.3 cm) cuttings of the terminal leader in summer and treat with rooting hormone. Caution, cuttings from lateral branches will produce irregularly shaped trees. Additional cuttings made from laterals that develop into terminals after removal of the original terminal leader will produce acceptable plants. Note that this tree is commercially produced from seeds.

Dip the bottom of the cutting  in a good quality rooting hormone - be sure they are well coated with the hormone. They root best with room temperatures of 60 degrees F. Provide indirect light (a north or east window) until they have rooted. The cutting should be inserted in moist sand or any commercially packaged rooting medium made for the purpose of rooting cuttings. The tip cutting, pot and all should be placed into a large clear plastic bag with a few pin holes poked into the bag in order to keep the cutting and atmoshpere around the cutting moist. The rooting media must never be allowed to dry out, or remain too soggy.
