Can Gardenias Be Pruned in the Summer?

Gardenias bloom best with limited, carefully timed annual pruning.

Gardenias are fragrant evergreen shrubs that have yellow, cream and white blooms. Pruning gardenias keeps them growing in the desired shape, but it must be done at the right time to avoid cutting off blooms or stressing the plant.

Blooming and Bud Formation

Gardenias bloom between late March and June, depending on the cultivar and location. Blooming is largely finished by mid-July, according to University of Arkansas Extension. Pruning must be completed before the buds for the next year's growth form in the fall.

Time Frame

Prune in the summer, as soon as gardenias finish blooming. Sometime between mid-July and September works best. Complete pruning before October 1 to ensure good bloom production next growing season. Ideally, pruned gardenias attain at least 4 to 6 inches of new growth by October 1.

Considerations

Limited pruning keeps gardenias looking their best and growing well. Prune only as needed to maintain a good shape and cut off dead or diseased branches. Carefully pruning gardenias in this manner encourages abundant blooming on new growth.
