Full Answer

  1. Water the roses

    Water Knock Out roses often during the first month after planting, keeping the soil moist. Once established, only water the roses when the top 1 inch of soil becomes dry to the touch. Do not apply water to the foliage since this can encourage disease.

  2. Apply fertilizer

    Fertilize Knock Out roses twice in early spring with a balanced fertilizer, reapplying the fertilizer every four weeks until the middle of August.

  3. Prune selectively

    Trim out any dead wood at the end of each winter. Shape the bush, opening up the center by removing any crossing branches. Follow the natural lines of the bush, trimming the branches back to one-third to one-half of their original lengths to maintain the best shape.

  4. Mulch in the winter

    Apply straw to the base of the plant to protect it from severe winter temperatures. Remove the straw from the plant as soon as temperatures warm up.
