Hello

I have 4 catnip plants that I recently bought from a garden center.
Here's a pic.

Plants are about 6" high.

Basically my aim is to grow as many of these as quickly as possible (my
cat's love them so much!!!) and I've heard a little about taking cuttings
from plants and growing them up but I was wondering if these plants are too
young to do it with at the moment.

Also I don't know how to take cuttings, I have 0 gardening experience so any
advice would be greatly appreciated

Thanks very much
