‘Pink Double Knockout’ roses at UT Gardens in Knoxville, TN<\/p><\/div>\n

Knockout\u00ae roses continue to wow gardeners across the U.S. (USDA hardiness zones 5 to 9). The original Knock Out series grew 5 to 8 feet tall and 4 to 6 feet wide. Shorter growing Double Knockout\u00ae series\u00a0make better fit in most urban gardens at 3 to 4 feet high and 3 to 4 feet wide.\u00a0Double blossoms have the look of hybrid tea or floribunda roses. Colors range from red, pink, coral, and yellow.<\/p>\n

All Double Knockout roses are bred for its resistance to common rose\u00a0pests and diseases. They bloom heaviest in May and June, retreating in the heat of summer and finish with a flurry of color in late summer and fall. They hold up\u00a0under rough weather\u00a0and moderate drought.<\/p>\n

Roses are best planted\u00a0from spring thru mid-summer to permit roots adequate time to\u00a0grow deeply\u00a0before winter arrives. Double Knockout\u00ae roses should be planted 4 feet apart in a garden site that receives 6 to 8 hours of sun most days and in well-drained\u00a0soil that ranges between pH 6.0 and pH 6.5. Roses need good air movement, so don\u2019t crowd them.<\/p>\n

Dig a wide hole to accommodate the roots from the container grown plant. Set the root ball slightly shallow in the hole. Backfill the hole with soil and water deeply. After planting, water\u00a0regularly (usually weekly) until the plant\u00a0becomes well established. Apply 2-3 inch depth of an organic mulch to conserve soil moisture and reduce weed infestation. Do not pile mulch around the rose trunk.<\/p>\n

Fertilize\u00a0Double Knockouts\u00a0with a water-soluble fertilizer monthly from early spring\u00a0until September 15 (no later). An alternate feeding\u00a0method is to\u00a0use special organic based\u00a0rose foods sold at most garden centers.<\/p>\n

In late winter or early spring\u00a0prune roses when they are still dormant to remove\u00a0all dead or damaged wood and to maintain the roses at a desired size.<\/p>\n","protected":false},"excerpt":{"rendered":"
