Okay, I have begun the experiment using Xenox, Bertram Anderson, Plum Perfection, Chocolate Drop and Blue Pearl. We will see how this goes.
I took one stem cutting from each, except Bertram Anderson (2 stems). I cut each stem into 3 pieces and have them drying (callousing over). It is so hot here right now I think they will be ready to plant sometime tomorrow. I will use rooting hormone on each piece before planting into 5" pots. I placed the pots on the covered deck for some early morning sun, shade the rest of the day. Keeping my fingers crossed.
