I have never rooted a cutting before, but this year, while messing around with my hydrangeas, I accidently snapped off a stem. It was a new green stem. I quickly dipped it in rooting hormone powder and have stuck it in regular potting soil. I'm keeping the soil damp, misting it and storing it in an east-facing windowsill. Am I wasting my time or is there a chance this will work? Thanks.
