Rose, Knock Out Growing Instructions

Knock Out rose prefers a spot with full sun and moist, but well-drained soil. Knock Out rose also appreciates a layer of mulch over the soil, especially in hot-summer climates to help keep the ground cool and moist. The best time to prune Knock Out rose is in the early spring, just before it breaks dormancy. Fertilize the plant in the early spring with a slow-release granular fertilizer. Like most roses, it grows best in a spot with good air flow and when its leaves don't get too much water on them from sprinklers.

Knock Out rose is not recommended for human or animal consumption.
