I have woolly aphid on the box, not sure what to do, when I cut the affected growth to trim back the box the aphids get air born and I don't want to breathe them in and also don't want to use poison that could irritate airways. I wonder if I should think about getting rid of some of the box hedging, is this going to come again every year now?
@Jade3 , Not quite sure what that is I'm afraid. I think I've had it on my box hedge in the past but just left it. You may find the birds will eat it all. I expect some of the other posters will have better ideas.
Not to worry too much. It looks like Box sucker. Common on new growth in spring. They feed off new leaves and cause them to cup a bit, but this is just superficial. If your shrub is well established, just give them a trim around mid June onwards. They don't attack beyond that time.
