How can I effectively trim a pear tree to promote healthy growth and fruit production?

To effectively trim a pear tree for healthy growth and fruit production, prune in late winter or early spring before new growth begins. Remove dead or diseased branches, as well as any crossing or crowded branches. Aim to create an open canopy to allow sunlight and air circulation. Cut at a 45-degree angle just above a bud or lateral branch. Avoid over-pruning, as this can reduce fruit production.
