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

To properly prune a weigela bush 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 back any overly long or straggly branches to maintain a balanced shape. Avoid cutting into the woody stems too much, as this can reduce flowering.
