My knockout rose bushes are not blooming and the leaves are green; however, some are turning red (leaves). The plants have only been in the ground for approx. 2 months. Prior to planting they had a lot of blooms. What can I do to them?
Knockout Rose Bush
The best thing you can do is wait and keep them watered. They are working to get their root systems well established to support the new growth and more nice blooms. It is common to have a lull period after transplanting the blooming rosebushes into your rose beds. The transplanting does shock them a bit. The new redish to maroon growth is typically a good sign in that from that growth will come the new buds and blooms. To help the root systems get growing well and help the rosebushes get over any shock or stresses, mix some root stimulator and a product called Super Thrive into the same water and give the rosebushes a gallon of that that mix three times at about 5 days apart. Follow the label as to how much to use for the amount of water in your can. It is okay to mix both of them in the same water. That should help get them going well.
