Plant Information

Plant Care

Rainbow Knockout Roses require minimal maintenance while providing maximum garden impact. Water deeply once per week, ensuring soil remains consistently moist but not waterlogged. Apply a balanced rose fertilizer monthly during the growing season. Deadhead spent blooms to encourage continuous flowering and prune in early spring to maintain shape and promote healthy growth.

For optimal disease prevention, ensure good air circulation around the plant and avoid overhead watering. While naturally resistant to common rose problems like black spot and powdery mildew, regular inspection for pests and diseases is recommended.

Planting Instructions

Plant your Rainbow Knockout Rose in spring or fall when temperatures are moderate. Dig a hole twice as wide as the root ball and equally deep. Mix organic matter into the native soil before backfilling. Position the plant at the same depth it was growing in the container, spreading roots outward.

Water thoroughly after planting and apply a 2-3 inch layer of mulch around the base, keeping it away from the stem. Space multiple plants 3-4 feet apart to allow for mature growth and proper air circulation.
