Knock Outs bloom on new growth, so old, dead, or broken canes should be the first to go, cutting them back to the base. Knock Outs tend to grow in phases bloom - rest - bloom. If a mid-season trim is in order, it is best done following a blooming period while in the resting phase. Deadheading will also help to stimulate new bloom clusters and overall growth. Knock Outs tend to produce a lot of rose hips that inhibit flowering triggering dormancy , so trimming these off will keep your Knock Out blooming.
In warmer climates, leaving the rose hips on through fall and winter helps trigger dormancy. So instead of deadheading the last blooms of the season, simply remove the petals, allowing the rose hips to form. In colder climates, roses are naturally triggered to go dormant, but in warmer climates they may need this nudge. Pruning is vital to the health of the rose bush, it helps prevent disease by removing areas that may harbor infestations and also encourages flowering.
Your roses may look stark after a good pruning, but roses grow very prolifically and will fill in quickly. Following these few simple rules will ensure your roses are happy, healthy, and will provide you with a season of beautiful blossoms.

Follow our step-by-step advice on how to prune modern shrub roses. Bush roses include cluster-flowered floribundas and large-flowered hybrid teas, and have been bred for their ability to flower freely on strong new growth made during the current growing season. This means they can be cut down hard every year to keep plants compact.
Patio roses are shorter-growing forms of bush roses. Meanwhile, miniature roses simply need to be encouraged to produce thicker stems that will be topped with blooms, while any thin, unproductive twigs should be removed completely. Follow our step-by-step advice on how to prune bush roses. Rambling roses are vigorous, scrambling plants that can be used to cover walls, pergolas and even climb through trees.
They usually flower once a year, in June, producing a magnificent display of blooms. Species roses come from all over the globe and like ramblers, are robust and vigorous. There are lots of species roses to grow, including Rosa complicata , Rosa moyesii and Rosa glauca. Rambling and species roses as well as ground cover varieties some of which share parentage with ramblers and climbers flower most freely on a framework of stems that have been made in the previous couple of seasons.
This means that the oldest flowered stems are cut out each year to encourage new shoots to form from the base and to stop them turning into a tangle of unproductive stems.
