About half the apples have codling exit holes. I have used pherome traps on the allotment trees, not much use. Grease bands were ok and I lay down a bag of buckwheat hulls that I had just for somewhere to get rid of them. They did make my soil nice to how btw
I was thinking last night, that year my allotment apples were extremely unblemished and I never put this theory together until last night. My plan this year is grease bands, putting chives and dll below, for distraction scent and preditors and I have some hulls, which I will put around each tree. Maybe diatomaceous earth will work around the tree too. I will try all these, they are all organic methods
As an aside, I did a little light summer pruning and will set to for the open centre shape in winter this year. The whip, I will take down to half its height, so that I get the branches to make that bowl shape. All my trees are M26 rootstock thankfully and very well staked
