How to Deadhead Roses the Right Way So They Keep Blooming
You can maximize the floral show by taking the time to snip off blooms once they've faded. You'll be rewarded with a tidier-looking plant that will soon fill your garden with new flower buds.
Removing wilted blooms (known as deadheading) from your roses is an easy way to give your garden a tidy appearance. It also encourages your plants to produce new flowers. How to deadhead roses depends on their type, but in general, the easiest way is to just snip off the spent rose at the end of its short stem, above any foliage. Removing the old blooms stops the plant from putting energy into developing seeds, and instead encourages it to produce more flowers. Not all roses need deadheading, and some need a little more care than just snipping off the old blooms, so be sure to follow the tips below for the variety you're growing. Other than knowing which type of rose you're working with, all you need for the job is a good pair of gardening shears.
Deadheading Hybrid Tea Roses
The general rule for deadheading hybrid teas is to find the top set of five leaflets, then cut the stem below that, at the second set of five leaflets. But you won't hurt the rose if you cut it back higher or lower than that. In late summer to early fall, you can also just cut off the bloom itself. This will result in more stem and leaf growth, which is important for roses heading into a dormant winter period. However, if you do this earlier in the season, the roses will produce more flowers on shorter stems. Hybrid teas are prized as long-stem roses, so you could end up cutting away one of their best features if you deadhead them early.
Deadheading Floribunda and Spray Roses
Instead of producing a single flower per stem like other varieties, floribunda and spray roses tend to produce clusters of blooms. When you're deadheading, you can make your cuts anywhere below the entire cluster of spent roses along the stem from which it grew.
Deadheading Shrub Roses
A lot of shrub roses, including the famous Knock Out, are bred to shed spent blooms on their own. The good news is you might never need to deadhead these self-cleaning roses, but you still might want to clean them up based on how they look. And because shrubs only produce flowers from new growth, trimming them back will produce more branching and fresh growth, which increases the potential quantity of blooms. Deadheading Knock Out roses and other varieties of shrub roses is simple: Just remove the flower and its short stem.
How to Prune Roses
Usually, you won't have to do much pruning for most varieties of roses. In spring, take a good look at your plants to 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.
Just avoid pruning roses in the fall. Because pruning of any type 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, it's a good idea to prune tall modern roses, like hybrid teas and grandifloras, down to about four feet in the fall. This pruning, called "heading back," helps keep the plants from whipping around in winter winds.
Regardless of the type of roses you're growing, don't stress about deadheading! Unless you really start hacking away at your plants, it's difficult to deadhead them too much. Once your roses start blooming, just take a stroll through your garden every few days with your shears, and snip off any blooms that have faded away. It won't take much time, and it can make a big difference in how long your blooms last, and how many flowers your rose bushes produce each year.
