How to Trim Dead Magnolia Tree Branches

Prune dead branches from your magnolia tree to keep it healthy.

Magnolia trees can reach up to 80 feet in height and can spread up to 30 feet. The magnolia tree has many light pink blossoms that grow in the early spring. The tree grows well in USDA Plant Hardiness Zones 5 through 9A.

Prune magnolia trees to remove broken, dead and diseased branches to ensure that the tree remains healthy and to keep entryways and walkways clear. Prune the magnolia tree once it stops flowering in the fall or winter months.

Things You'll Need

• Saw or pruning clippers
• Tree sealer

Instructions

1. Inspect the magnolia tree for dead branches. The branches may look diseased, and they will appear brittle and possible broken already.

2. Examine the dead branches on the tree to determine what you will need to cut them. Thicker branches will require a saw, while pruning shears will suffice for thinner branches.

3. Make a straight cut as close to the branch as possible. Cut smaller branches close to an adjoining branch. Ensure that you make the cut as straight as possible.

4. Seal large branches with a tree sealer. This will prevent sap from seeping from the branch. You can purchase this at most nurseries. Follow the directions on the sealer carefully to ensure that you apply it properly.

5. Shape the tree after you remove dead branches. Prune up to one-third of the tree to control its shape to keep it looking neat and uniform.
