Holly is being eaten
We moved into a new build around 3 yrs ago. At the front they planted a bed with 1/2 hebes and 1/2 holly. The 3 or 4 holly nearest the hebes are having there leaves eaten. Quite a lot of circular chunks out of leaves. The nearer the hebes the worse it get. Could there be any from one getting onto the other and eating it. If not what is eating the holly. Any help please.
