How can I properly care for a weigela bush to ensure its health and growth?

To properly care for a weigela bush, plant it in well-draining soil with full sun exposure. Water it regularly, especially during dry periods, and mulch around the base to retain moisture. Prune the bush after flowering to promote new growth and shape it as desired. Fertilize in the spring with a balanced fertilizer. Keep an eye out for pests and diseases, and address any issues promptly.
