Florist rose cuttings & superthrive
For the last year or so, I have been taking cuttings from bouquets of florist's roses and have had only moderate success. The ones that actually did take have been doing very well in my garden, but still, the death rate of my cuttings was pretty high and the majority of them would turn black.
Recently I purchased a bottle of superthrive because I was going to be digging up and moving a small evergreen and I was hoping to ease the transplant shock. Normally, when I plant rose cuttings, I start by mixing potting soil (usually scotts) with perlite. Then, I water it. Now that I have the superthrive, I wet the soil with that (I believe one capful per gallon)..
Doing that seems to have made a huge difference, and now about 70 percent of my cuttings are surviving. I had always used powdered rooting hormone, but I think this new stuff is what gives them the extra push to form roots. Anyone else doing this??
