Not knowing where you are or what hollies you're talking about, I can offer
some general advice. Prune before the new growth appears. On the tall
growers, make big, few, judicious cuts. On the small growers, you can shear
them like a hedge. Here in South Carolina, there's not too much you can do
wrong to a holly, any kind. They're very forgiving. give them a good
fertilizing once you see new growth.

rather than up? Also, What time of year is best?
