The canary's branches are too long, so they need pruning. Cut the branches short and protect the incision after cutting them short. Goldfinch pruning branches mainly has two periods, namely autumn and winter and spring after flowering. It is necessary to prune dead branches in autumn and winter to reduce the nutrient loss of goldfinches, and prune dead, unhealthy and overgrown branches after flowering in spring to reduce nutrient consumption and promote the next flowering.
