Pruning holly in the autumn

Asked October 5, 2016, 9:54 AM EDT

I have some overgrown holly bushes/trees that have become too tall. The worst ones are around 15 feet high. I would like to cut their height down to half of that. It is now October and I read that holly should not be pruned in autumn because the new growth that would arise would die with the cold weather. But I wonder, would this actually help slow down future vertical growth? Are there other consequences to autumn pruning that I should worry about?

Pruning will stimulate new growth. Holly should be pruned when dormant, this would be from late December to early March.Plants store nutrients in their root system for next season's growth. Pruning at the wrong time of the year can exhaust it's food reserves.
