Gardenia bushes are best known for the sweet smelling, white blossoms they produce each spring, according to the National Garden Association. This evergreen shrub grows best in soils with pH ranging between 5.0 and 6.0 that is well draining. Gardenia bushes can mature to sizes ranging from 2 to 8 feet in both height and width. Pruning gardenia bushes at the right time with the appropriate tools helps ensure a healthy and well-shaped plant. Most gardenia bush pruning needs to be done every other season.
Inspect your gardenia bushes regularly and prune all damaged, weak or broken branches at any time. Always use sharp pruning shears to create clean cuts and avoid unwanted disease from rough cuts.
Dispose of diseased cuttings far from your gardenia bush and other plants to prevent disease from spreading.
Prune the flowers off your gardenia bush when needed. This will encourage more blossoms during the growing season.
Cut branches to control the overall size and to maintain a natural shape in the fall after all flowers have blossomed. Thin out the bush by removing some of the interior branches to allow better airflow and light penetration.
