I have a huge Pointsetta ( rose) that was given to me 3 years ago. Last year we had to use a Fridge box to cover it. It has bloomed fantastic for me. It is over 42 inches tall. Now my question is this....The stalks are very large and woody and is now starting to look very shabby. How can I get cuttings off of it to start another one? It is still blooming like crazy.
