Rosa Home Run is a trademarked hybrid cultivar of the Knockout rose and was bred to produce very dark, rich-red flowers with a single layer of petals. Like its Knockout rose parentage, Home Run is highly disease-resistant to the common rose maladies of black spot and mildews. It is hardy in USDA zoned 5 through 9 and will bloom from spring until the first hard frost in the fall.
Water your Home Run rose consistently and deeply to keep the soil evenly moist at all times. Allow just the top inch or so of soil to dry out before watering again. Water low on the soil with a gentle stream to prevent splashing the canes and foliage with water or soil. Never water over the top of the rose as this encourages a number of diseases.
Feed your Home Run rose several times a year with an organic or slow release rose food. Look for products with a guaranteed analysis of 5-10-10 or similar ratio. Apply according to the product label dosing directions, over the entire surface of the root mass, but away from the trunk and main canes. Nestle granular fertilizers into the top inch or two of soil. Water in well until the surrounding soil is drenched several inches down.
Mulch around the base of your roses each fall with 2 to 4 inches organic material such as cocoa bean hulls or shredded bark. Keep the mulch about 6 inches from the trunk or main canes to prevent rot and insect breeding in that sensitive area.
Harvest fresh blooms for use in cut flower arrangements just as they begin to unfurl. Prune away spent flower heads remaining on the rose as they fade. Place the cut at the desired place on the cane and just above a leaf axil or bud. Remove any broken, damaged or diseased canes and foliage when you spy them.
Clean up all the cuttings, dropped petals, leaves, stems or any other debris that gather beneath your Home Run rose. Extraneous material on the soil surface, save mulch, serves as a breeding ground for disease and insects.
