Preparing mini roses for winter
My 3 mini roses (potted grocery store minis that I planted outside) have lost many leaves from black spot. I sprayed them with a fungicide and removed all the spotted leaves. What leaves are left seem healthy, although not abundant. They are flowering. Now it's late September and I would like to know what I should do to prepare these guys for winter. Do they get trimmed back, wrapped, or what? Thank you.
