    It really depends on what type you are caring for. Hybrid Tea, Shrub, Knock-Out??? Some will require cones, while the newer Knock Out Rose don't need any covering in the winter.

    i guess my main question is i have seen some people trim them like 3-4 inches from the ground and then cover them with mulch is that a good way to do it or not

    Wait till the first of march and cut them down to 16 inches unless their way overgrown then cut them back now.

    you don't do any cutting, just make sure you have enough mulch to protect the roots from the killer frost.

    Lots of factors involved, but generally you want to make them less susceptible to breakage due to snow loads and wind damage over the winter. Thin them out, bring them down, and mulch the root area if you have to worry about frost heave. Thawing and re-freezing can leave air spaces around the roots (And roses don't have very good root systems) which can eventually kill the plant, and mulch stabilizes the temperature, reducing or eliminating frost heave.
    In the spring, prune the roses according to what you want the growth to do, cut out all dead/discolored wood, and scrape the bud union to promote new meristematic growth which will give you additional canes. Feed them lightly with triple super-phosphate (Stay away from nitrogen) and watch for bugs/mildew.
    Good luck!

    I will prune back shrub roses a bit in the fall. If the customer has any of the hybrid tea roses or other premium rose, I cut down to 4-5 inches and pop a large rose cone on it. Some people will put mulch in the cone also, but I do not. Have had good success - we are zone 4b-5a.
