The trees look OK for the most part, a little more of the Powdery Mildew has appeared, but the only things really thriving are the Aphids. The growing shoots on most of the trees are covered in Green Aphid, and two of the Tremlett's are badly infested with the dreaded Rosy Apple Aphid. They're also infested with hungry Harlequin

The problem with Rosy Apple Aphid is that when the critters latch onto the underside of a leaf, it curls over to cover them. Whilst this makes an infestation easy to spot, it makes the job of control that much harder. I've been forced to restore the balance on these trees with a dose of fatty acid insecticide spray, but even so, it's probably an early bath for these Tremlett's and we won't see much more growth from them now. As you can see from this pic, the damage extends to the shoot itself, the growth of which is now distorted and will probably need pruning out this Winter.
