Fairy roses not flowering

Asked August 25, 2017, 2:48 PM EDT

We have 5 very healthy fairy roses in our yard but only one flowers. They all get at least 10 hours of sun per day and we have fertilized them. Do you have any suggestions on how we can make them flower?

Thanks for your Fairy Roses not flowering question. Fairy Roses are fragrant shrub roses known as polyanthas, named for the multiple blooms at the terminal ends of branches. They are very drought tolerant and disease and pest resistant. One of the best old polyantha, known as “The Fairy” was introduced in 1832. Fairy Roses continue to be widely planted because of their vigorous growth and reliable production of pink, fading to white, blooms from spring until winter’s first frost. If your roses are healthy with fertilizer, it is possible that the glossy box hedge foliage remains healthy on second year or older canes. Polyanthas bloom on first year cane. Fairy Roses can be kept looking good with some attention in early spring. Cut or deadhead spent blooms on all polyanthas during summer and fall as they are not self-cleaning like many newer landscape shrub roses.

Complete an annual pruning in late winter when the first buds begin to show, cutting out any winter-killed canes at least 1 inch past the damaged or dead area or until you find green wood with a white center, which indicates living tissue. Annual pruning is necessary because polyanthas bloom on new wood that grows in the current year. Removing old wood transfers the nutrients they might consume to new growth and helps keep the center of the shrub open for good air circulation.

Cut canes back between ¼ to 1/3 the length of each cane down to 2 or 3 buds above where it started growing last summer. Pruning annually in this manner will produce blooms and maintain their shape.
