How to Prune a Purple Magnolia

Purple magnolia (Magnolia liliiflora) is a deciduous shrub that flowers from the spring to late summer. It gets its name from its appearance. The bush is dark purple-red on the outside and pink on the inside of the foliage. As long as purple magnolia is planted in the full sun, it grows 6 to 10 feet tall. While it is blooming, purple magnolia attracts attention and is the focal point of the garden. Prune it to improve the health and shape.

Instructions

- 1
  Prune purple magnolia after it finishes blooming. The plant blooms on last year's growth so late winter or early spring pruning -- which is common -- ruins the current year's flowers.
- 2
  Eliminate branches that compete with the central leader. Purple magnolias have a main trunk so prune competing branches. Shorten them by cutting just above a bud.
- 3
  Cut off branches that appear to be damaged or diseased. Cut them off where they meet healthy wood.
- 4
  Prune branches that rub against each other or cross. They are clogging up the interior of the tree, preventing air circulation.
- 5
  Remove suckers, sprouts and wayward branches. Anything affecting the overall appearance of the purple magnolia can be cut off. Cut them at the joint they share with other branches. Cut just above a bud to shorten wayward branches.
- 6
  Trim branches with narrow crotches. If they are connected to other wood with a V-shaped connection, they are weak and should be cut off. Keep branches that have U-shaped joints.
