It's a 11-12 year old plant. It's limbs twist and turn not straight like a tree but more like a dwarf bush. It's leaves have always been a garnet color and never have had a problem. I haven't had to fertilize it but will if you think that would help. No changes in water, drip irrigation morning and late afternoon. Sunny in the morning until noon the sun then moved behind the house and it's in shade of the house afternoon. I don't know what an alphid is but I see my knockout roses beside this bush also showing signs of some type of attack to its normally vibrant green leaves. It was suggested to use Neem oil on them. ?? Just not sure what type of insecticide would help, or if that's the problem. Picture of closeup and the picture of what is healthy.
