 Consulting Rosarian Tips for November:
I
f there are any signs of blackspot or powdery mildew lingering in your rose garden, sanitize by removing diseased leaves to eliminate the potential of harboring spores over the winter. When roses have gone dormant, you may use a fungicide spray to get rid of diseases by spraying the rose bush, around the surface area of the rose, and the surrounding areas that could harbor diseases.

Winter protection helps to shield roses from freezing, from the drying winter winds, and to lessen the effects of the freeze/thaw cycles as spring emerges. When roses are exposed to pro-longed periods of low temperatures (23 degrees or lower), they go into a state of dormancy. Roses with southern exposure or ones planted against a brick wall are less vulnerable and would require minimal protection. Shrub roses and own root roses are hardier and can do well with minimal-to-no winterizing, while rose varieties such as hybrid teas, some modern roses, or minis will benefit from winter protection.

Once we’ve had a few nights with temps in the teens or 20s, but before single digits, you can protect your semi-hardy roses by using a few shovels of dirt to cover the base of the rose, especially if the graft is exposed. If your roses are exposed to the elements, a rose collar can be purchased or you can make one using wire and place about 12 to18 inches of mulch inside. When applying winter mulch, be sure that air and water can get down to the roots, so apply loosely—do not pack the mulch. After roses become dormant, evaluate rose canes. If they are taller than 3 feet, you may want to consider cutting them back to prevent breakage from heavy snows.

On warm days during a dry winter, water roses midday before another cold spell to ensure that the roots are hydrated. Roots suffer more in dry soil than in wet soil.
