How can I properly prune a weeping cherry tree to ensure its health and beauty?

To properly prune a weeping cherry tree for health and beauty, start by removing dead or diseased branches. Next, thin out crowded areas to improve air circulation and light penetration. Trim back any branches that are crossing or rubbing against each other. Finally, shape the tree by cutting back long branches to maintain its graceful weeping form. Avoid over-pruning, as this can stress the tree.
