Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to prune a magnolia tree [title] Prioritize dead and diseased branches over healthy branches. [step] With magnolia trees, removing healthy, if unattractive, branches may cause more harm than good. You should never prune more than 1/3 of the tree at once, so always start with branches that are either dying or already dead.

Ending1: [substeps] Every 1/3 of the tree should be dead and two branches should be healthy. A pruned tree will be able to turn colors from the other branches as opposed to the white ones you intend to remove. Ending2: This will prolong the growth of the diseased of the branches. Also, because dead, diseased branches are usually dormant, prune the diseased branches at least twice a day. Ending3: [substeps] When in doubt, be conservative with what you trim. Magnolias are very sensitive to pruning. Ending4: [substeps] If you see dead and diseased branches, it's best to remove those as well. Other branches may require pruning to help the tree flourish, and you don't want old, unhealthy branches falling off.
