Q.Rose has bright pinky/red, green and yellow leaves and stems and looks like the stems will be blind.
This rose is “The anniversary rose” and is 8 years old. it has been pruned properly each year and always grows to about 6′ tall. This year the growth is good, as usual, but is a startling bright pink/red, yellow and green colour, blotchy with pale stems. It is not showing any buds at present.
Can you tell me what is happening to this rose please?
I suggest looking at the underside of the leaves. Such damage on the new growth could be a worm or slug that eats the underside of the leaves and makes them look skeletonized. You may not be able to see the worms/slugs during daytime but can with a flashlight at night. It does not look like a fungus from the photo provided. Spraying the roses with a systemic type insecticide should control any worms. Be sure to get the spray up underneath the foliage when spraying.
