What should I do with these roses. I never did anything to them before winter but last year 2 died. I have a bale of hay that l will throw out after Thanksgiving and I also live in Illinois. Should I spread the hay around the base of the plant for extra protection? Thanks.
There must be some factor other than the winter that caused your roses to die. Knockout roses are hardy to zone 5. You should cut the roses back and then apply a thick coat of mulch to the ground( 4" minimum). In extremely cold climates some people cover their roses with buckets or small barrels and then insulate around those. Your own experience shows that they survived before. Check to see if they were weakened last year by aphids or some other pest or by any changes in watering. They should survive unless they are already stressed by something else before winter starts.#If you have any other info about this subject , Please add it free.# |
