Hi, what is the best way to protect roses and hydrangeas from midwest winters? Are styrofoam cones necessary or just mulching, etc? When do you cut back hydrangeas? thanks Lee

After the first frost kills the leaves you can cut your plants back and protect them from winter weather. Styrofoam cones are fine, or you can fashion cylinders out of chicken wire to place around the plants, then fill in with shredded leaves, pine needles or other organic matter to provide insulation. At the end of the season simply remove the cylinders and use the organic matter as mulch on the soil around your plants. Best wishes with your landscape!
