How should I properly prune a weigela plant to ensure healthy growth and abundant flowering?

To properly prune a weigela plant for healthy growth and abundant flowering, prune it in late winter or early spring before new growth begins. Remove dead or damaged branches first, then trim back about one-third of the oldest branches to encourage new growth. Cut branches at a 45-degree angle just above a bud or lateral branch. Avoid cutting back too much at once to prevent stress on the plant.
