How hard can you prune rosemary? I bought one last week that has leaves

only grow from the newer growth?

Only from the newer growth. Once they start to get woody at the bottom
it is time to start some cuttings, or decide that you like it that way.
The Impatient Bonsai Master that came into our nursery used to prefer
them - clip, clip instant bonsai.
