‘Knock Out Red’ Rose (Rosa ‘Knock Out Red’). The ‘Knock Out Red’ Rose is a vigorous, floriferous shrub with a bushy, rounded habit, known for its exceptional bloom and remarkable disease resistance. It produces an abundance of intense cherry-red single flowers that continuously renew from early summer until the first frosts. Its glossy dark green foliage remains healthy all season, even in difficult conditions, making it a very reliable choice for low-maintenance gardens. Ideal for beds, borders, or group plantings, it effectively structures full-sun landscapes.

To plant the ‘Knock Out Red’ Rose, choose a suitable exposure: full sun. The recommended soil is: rich, well-drained. Water at the base and allow air to circulate between the branches. Remove dead parts with a clean tool, then prune according to the rose's group. Winter protection depends on its hardiness and the potential presence of a graft union. Water the root ball before planting and ensure water can drain after planting. During establishment, check the moisture by hand before watering again.

Allow a width of 1.2 m (4 ft) to arrange this plant's space in the garden. The indicated height of 1.2 m (4 ft) helps choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Combine this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Potted roots are more exposed to cold than those planted in the ground.
