Rose Selection

Select varieties that are adapted to and hardy in your growing region. Look for disease-resistant varieties such as ‘Bonica’, ‘Carefree Wonder’, ‘Cecile Brunner’, ‘Livin’ Easy’, ‘Martha Gonzales’, and ‘Old Blush’ to reduce the need for pesticides.

Certain characteristics indicate how susceptible a rose might be to insect attack. For instance, light-colored roses (whites, yellows, and pinks) are the most attractive to pests. As a rule, modern roses (such as hybrids teas) are also pests’ first choice. Their blossoms feature high, pointed centers and tightly packed petals where pests can hide, making the critters more difficult to keep in check. Shrub, species, and old-fashioned roses have more open flowers and branching habits, making pests easier to spot and control.

Rose Care

To help roses establish a sturdy root system, moisten the soil to a depth of 18 inches every week during the growing season. When rainfall is inadequate, soak the soil by hand with a garden hose, or put the roses on a soaker hose or drip irrigation system set on a timer.

Fertilize when new growth first starts in the spring and again in midseason with a natural formulation that feeds the soil as well as the plant.
