Most other softwood cuttings were rooting very easily and with acceptable levels of success, but for several reasons we did not like the results we were getting with these plants. Defoliation, very weak root systems and stem rot seemed the norm.

Since heat, mist, soil mix, and rooting hormones were working with the other plants, we decided it was time to rethink the situation in regards to the mentioned plants and their cultivars.
