How to deadhead roses depends on their type, but in general, the easiest way is to snip off the spent rose at the end of its short stem above any foliage. Deadheading also helps your plants to produce new flowers since removing the old blooms stops the plant from putting energy into developing seeds and encourages it to make more flowers.
Not all roses need deadheading, and some need a little more care than just snipping off the old blooms, so follow our tips for the variety you're growing. Besides knowing which type of rose you're working with, you only need a good pair of sharp gardening shears for the job.
Deadheading Floribunda and Spray Roses
Instead of producing a single flower per stem like other varieties, floribunda and spray roses tend to have clusters of blooms. So when you're deadheading, you can make your cuts anywhere below the entire cluster of spent roses along the stem.
Deadheading Hybrid Tea Roses
The way to deadhead hybrid tea roses is to find the top set of five leaflets, then cut the stem below that at the second set of five leaflets. You can cut off the entire bloom from late summer to early fall, resulting in more stem and leaf growth, essential for roses entering a dormant winter. However, if you do this earlier in the season, the roses will produce more flowers on shorter stems. By deadheading early, you could cut away hybrid teas' best feature—their long stems—so decide which you prefer, more flowers or longer stems, and deadhead accordingly.
Deadheading Shrub Roses
Many shrub roses, including the famous Knock Out, are bred to shed spent blooms on their own. The good news is that you might never need to know how to deadhead roses if you grow these self-cleaning beauties.But you still might want to clean them up based on their appearance.
Because shrubs only produce flowers from new growth, trimming them back will make more branching and new growth, which increases the potential quantity of blooms. How to deadhead roses that are Knock Out and other shrub roses is simple: Remove the flower and its short stem.
Tips for Pruning Roses
Usually, you won't have to do much pruning for most varieties of roses. In spring, look carefully at your plants and cut dead canes (stems) as close to the ground as possible. Spring is also the best time to cut back the tops of rose bushes if you want them to have a uniform shape.
Avoid pruning roses in the fall. Because pruning spurs more growth, stop deadheading or cutting blooms for bouquets a few weeks before your area's first frost date. As the weather gets colder, your roses will begin to go dormant, moving their energy reserves into their roots to help them survive the winter. If you keep pruning throughout fall, this process will stop.
However, in the fall, it's a good idea to prune tall modern roses, like hybrid teas and grandifloras, down to about four feet. This pruning is called "heading back" and helps keep the plants from whipping around in winter winds.
Regardless of the type you're growing, don't stress about how to deadhead roses. Unless you start hacking away at your plants, it's hard to deadhead them too much. Once your roses blossom, stroll through your garden every few days with your shears and snip off faded blooms. It won't take much time and can significantly affect how long your rose blossoms last and how many flowers your rose bushes produce yearly.
