I wanted to take some cuttings of rosemary before cutting the bush back, and so got this. Following the instructions I took about 12 cuttings and dipped them in water, then into the powder and then put into compost.
So far I have about 9 that have taken and already look healthy and sturdy.
With the short period of what probably was our summer, I think a couple failed but don't think is indicative of the powder, just the circumstances of the cutting and preparation.
I have just tried using it to take a cutting of Golden Pothos and feel confident that this will do the trick!
