Scientifically known as the ​Rosa rugosa​ (U.S. Department of Agriculture plant hardiness zones 2 to 7), the beach rose is a sturdy, easy-to-grow shrub that's enjoyed by landscapers and home gardeners alike. Not only are beach roses cold-tolerant and disease resistant, they'll also withstand conditions that would send most rose bushes into a full wilt.


They thrive on poor soil, in salt air, in windy environments and in full sun. However, while they don't require the attention other rose bushes demand, they do need periodic trimming to look their best. Pruning beach roses eliminates old, unattractive or damaged wood, while promoting the growth of new foliage and flowers.

How to Trim Beach Roses

Step 1: Prune Before Spring Growth Starts

Examine the rose bushes prior to the spring growth spurt. Not only will the beach rose recover more quickly from pruning during the dormant period, but it will also make spotting unwanted canes easier as there is bound to be little, if any, foliage on the branches.


Step 2: Remove Dead Branches

Remove any branches that have been killed by frost. These will be a dull brown color and will have no buds or new growth on them. Hold alcohol-sanitized pruning shears at a 45-degree angle and cut the branch, removing as much of the dead plant tissue as possible. Cut the branch back to the base of the shrub, if necessary. If you're not sure where the dead wood ends and the healthy growth begins, simply look at the center of a cut branch. Living canes are white in the center, while dead canes are brown.


Step 3: Trim Damaged Canes

Trim any damaged canes, cutting them back to the place where they connect with healthy branches. Look for broken or split branches to remove. Additionally, remove any branches that are growing inward, toward the heart of the plant, rather than out toward the open air. This thins the shrub and allows air to circulate more freely around the branches, which helps to discourage the development of diseases.


Step 4: Prune Diseased Branches

Prune out branches on your beach rose bush that show signs of disease. You can prune diseased plant material as soon as you notice it any time of year, not just early spring, to keep the disease from spreading. Sanitize your pruning tools with alcohol before making each cut to prevent spreading the diseases. Common diseases that affect roses include black spot, powdery mildew and rust.

Step 5: Remove Crossing Branches

Eliminate crossed branches by cutting away the smaller or weakest of the two. If left unattended, the canes will rub against each other as they grow, damaging the protective bark and leaving the shrub vulnerable to invasion by pests.


Step 6: Trim Beach Rose Suckers

Examine the base of the beach rose shrub. Locate the bud where the branches emerge from the roots and trim away any growth found below this nodule. These offshoots are known as suckers and their development drains the energy resources of the plant. Removing them keeps your beach roses stronger.

Step 7: Sculpt Beach Roses

Sculpt and shape the beach rose shrub, if desired. Keep the overall shape of the bush in mind, retaining the overall shaping to make the bush look natural. Cut the canes back, removing up to one-third of each branch to control the overall height. Alternatively, you can remove whole canes, cutting them completely back to the base of the shrub, to control the width. Take care not to remove more than 30 percent of the total plant material. While the beach rose can handle heavy pruning, removing too much at once isn't ideal.
