Hardwood Cuttings from Trees. Progress Report.

I'm starting to think this propagation method is very good. Not just for figs. Fig cuttings root easily by almost any method. These were prunings I had lying around this winter. I did what I've been doing to jump start fig cuttings. Use cuttings about 6-8 inches long. As thick as practical - pencil thickness seems good.  Thinner or thicker seems to work. Make incision through bark and cambium layer using sharp pocket or kitchen knife. Dip in rooting hormone dip-and-grow at 1:10 dilution 1 to 2 minutes. Wrap in moist paper towel. Place into plastic bag and close. Keep in warm place.
These cuttings are from ornamental plum.  They have calloused well.  There is some top growth.  Not sure if roots are developing yet.  I think I see root initials.  So these are still in the "maybe" category as to whether they will develop into little trees.



Laburnum (golden chain tree) cuttings. These are also a few weeks old. Same method. The top cutting is a "mallet" cutting. It is a small branch. The base is trimmed with some remaining stem from the 2-year growth, trimmed.  The bottom cutting is similar, pruned just below the junction with the previous years' growth.  The middle cutting is just new wood.  All have calloused and are forming roots.  Some previous years' growth seems to work best.  Small sample size of course.  With these, some previous years' cambium seems to help.



Redmond American Linden. These have some callous. They leaked a jelly-like sap for a while. Not much. The root initials look promising.  They are also in the "maybe" category, as to whether I'll get trees from them.  If the tops grow too fast, they might overwhelm the almost embryonic roots.
