Thank you for your helpful reply! I've not found this specific info anywhere else. So it seems it does have a lot to do with the variety of the bush and I unfortunately have some that won't fulfill my joy. Out they go so that I can plant a different variety that will. I'm so sad I wasted 15 years.
And thanks for the tip about soft water!! We have a water softener and I have always used our sink water for cuttings. I will always fill buckets/vases from our garden hose from now on. For all our cuttings no matter tree/bush/or flower. Thanks so much for that insight!
