Why do my Knockout Roses have holes and greyish white spots on many leaves? Also, now they are starting to sprout some red leaves. . . is that normal?
Our knockout rose bushes have greyish spots on the leaves, which seem to eat a hole in the leaf right where the spot is. Our bushes are covered with them. We have looked carefully and it is not an aphid or any kind plant pest. Can you tell me what this is and how to get rid of it?
How frequently should Knockout Roses be watered?
Planted 5 knockouts last spring and they did great. This spring they bloomed and were beautiful. Then, about a month ago, I noticed one plant beginning to have wilted leaves. The leaves began to turn yellow, fall off, and the rose bush died. Now, 2 more are doing the same thing. That’s 3 out of 5. One bush looks healthy, has started re-blooming. And last but not least, the 5th bush, although re-blooming, now has very few leaves. Can you give me any ideas as to what may be happening. I have seen signs of voles in my yard for the first time and my neighbor says they are the culprit, but I cannot find any signs in or around the rose bed.
What do you do to get your Yellow Knock Out roses to maintain their yellow color? When they are in the bud stage, they are yellow; but when they are in full bloom, they turn white.
