8 Look for a Mile-Hi Fertilizer representative handing out FREE SAMPLES TODAY! Mile-Hi Rose Feed with KELP! WHY USE MILE-HI ROSE FEED?

Adding Mile-Hi Rose Feed to your soil improves moisture retention and enhances soil texture as it decomposes and releases. It encourages root growth while boosting overall plant health and it won t harm groundwater. DIRECTIONS FOR USE: Feed each large Rose Bush one heaping cupful and each mini Rose Bush one level 1/3 cup three times during the growing season. First Feeding: April 15 to May 15. Second Feeding: June 15. Third Feeding: July 30 to August 15. Pull away mulch and spread fertilizer around the bush out to the drip line. Scratch in lightly and water in well. Replace mulch.
