Perfect for accent, foundation and mass plantings.
Red Knock Out Rose Care
Plant in well-drained soil. Water deeply and regularly to establish and continue watering when soil becomes dry. Mulch to retain moisture and control weeds. Remove spent blooms to encourage repeat blooming. Prune in late winter or early spring.

Once your plant is shipped you’ll receive an email with tracking information. Depending on the above criteria we’ll ship your plant(s) towards the beginning of the following week from your order date. We put together this helpful guide for what to do when you receive your plants in the mail.
It is important to know that all of our plants are clearly labeled for which growing zones the plant can survive in. The plants are thoroughly trialed and tested in every growing zone before we state the plant can grow in a zone. Again, our #1 priority is to ship the plants to you healthy and ready to thrive in your location. So we will do everything in our power to do so.
