ALEXANDRIA
— Roses may seem like high-maintenance divas, but Minnesota gardeners know better. With the right varieties and a few smart habits, roses can be some of the most reliable, rewarding plants in a northern garden. Our climate rewards toughness, and fortunately, plenty of roses fit the bill.

Common rose diseases in Minnesota, and how to handle them
Minnesota’s humidity and cool nights can invite a few predictable issues, but most hardy shrub roses resist them.
Black spot: Dark leaf spots with yellowing. Remove infected leaves, water at the base and improve airflow.Powdery mildew: White coating on leaves. Prune for airflow and water in the morning.Rose rust: Orange pustules under leaves. Remove affected foliage and avoid overhead watering.Cane dieback: Stems brown from the tips. Prune to healthy tissue and plant grafts 1–2 inches deep. Botrytis blight: Buds brown and fail to open. Remove affected buds and improve air circulation.
