Trim Spent Blooms
Continue to remove or deadhead spent blooms on roses. For hybrid tea roses, trim back to a five-leaflet leaf on the stem. Trim floribundas, grandifloras, climbers, miniatures and shrub types just under the bloom head or spray. Allow rose hips to form on rugosa and old garden varieties.
Don't Retire the Hose
Continue to water roses and shrubs deeply, particularly those planted in full exposure or on slopes. You can get by with watering once every week to 10 days. Set a frog-eye sprinkler around the root zone and allow to run for 20 minutes or until the soil is watered to a depth of 4 inches or more.
Plant More Roses
Take advantage of fall savings and purchase container-grown rose bushes. Get them planted before the end of October to allow them to become settled in before the ground freezes solid. Water monthly during dry spells of fall and winter.
Condition the Soil
Fall is a good time to add some compost or sphagnum peat moss to the rose garden. Spread a few inches over the soil and lightly cultivate in so as not to damage the roots.
Plan a New Rose Garden
Want more roses in your landscape? Now is good time to walk around your garden and plan a spot for a new rose bed. Locate it where it can be viewed from the house. This will give you a head start in spring so you can order early and get your top choices before they sell out.
