Propagation by cuttings?
I haven't ever had any success propagating roses by cuttings, every single time the cuttings die. Without fail. I can successfully grow gardenia cuttings. Are gardenia's just easier? What is a step by step process to attempt to grow a rose cutting in a very hot and humid climate (Western TN)? What time of year should I start, and What the heck is callousing?? Thanks for the help,
