I have a few questions about propagating Hydrangeas.
Why is it recommended to cover the cuttings (usually with a plastic bag)?
Also, why is a soil less media recommended? I have vermiculite and
I'm contemplating using either vermiculite with vermicompost or just vermiculite. I also have soil moist I plan to mix into the media to help retain water.
Lastly, how long does it take for the cuttings to mature into a shrub that can bloom?
Thanks in advance for your help.
