How should I properly prune pyracantha to promote healthy growth and maintain its shape?

To properly prune pyracantha for healthy growth and shape maintenance, prune in late winter or early spring before new growth begins. Remove dead or diseased branches first, then trim back any overly long or crossing branches. Cut at a 45-degree angle just above a bud or lateral branch. Avoid cutting into old wood as it may not regrow. Regular pruning will help promote new growth and maintain the desired shape of the plant.
