They are recent converts to growing these plants but their gardens are a frequent feature in the Utah Rose Society newsletter. See them for roses that they think are the best and easiest ones for growing in Utah.
For more rose information contact the American Rose Society. Their web address is http://www.ars.org/. There is information there on the Utah Rose Society.

To keep your roses blooming throughout the summer, deadhead them properly. Cut the old blossom off at the first five leaflet leaves below the spent blossom. Most types will continue to bloom and produce another heavy flush of blossoms in the fall.
Roses are the most popular flowering shrub in Utah, the official national flower and June is the month of their glory. There are many fabulous rose gardens blooming around the state.
Like most other garden plants they get their share of pests. Use a thick mulch layer to keep weeds down and eliminate the need for herbicides except on the most persistent perennial weeds.
Bindweed and other nasty, deep rooted perennials are likely to need additional controls in the form of glyphosate which sold as Roundup or under many other different labels. be careful never to get any on the roses as it will cause very severe damage.
Insect problems in the early spring are usually limited to aphids. If ladybugs are moving up and down the stalks on warm days, then no control is needed. Otherwise use a summer weight oil, or insecticidal soap.
Spray the undersides of the leaves to prevent these sucking bandits and spider mites from feeding on your prize plants.
Thrips are more serious. these tiny creatures are about the diameter of a human hair and move very quickly. they cause the buds to be distorted and the petals to be malformed and are the most noticeable on white roses.
Organic controls are more difficult for thrips and you may need to use a systemic if the above mentioned remedies do not work. Controls for other insects can usually be delayed until they start to develop.
Diseases also develop on many roses. The major problems are powdery mildew, black spot, and rust. Fortunately only the powdery mildew presents serious problems for roses growing in Utah. Prune roses and surrounding plants to increase air circulation.
Organic controls include sulfur and baking soda. Preventative chemical sprays include Funginex by Ortho and Halt by Fertilome or Bayleton by Monterrey chemical.
