How can I effectively prune a kumquat tree to promote healthy growth and fruit production?

To effectively prune a kumquat tree for healthy growth and fruit production, start by removing dead or damaged branches. Then, trim back any branches that are crossing or rubbing against each other. Prune to maintain an open canopy that allows sunlight and air circulation. Avoid heavy pruning in one session, instead spread it out over time. Prune in late winter or early spring before new growth begins.
