Last year we had a bad infestation of raspberry beetle. This year we have hoed around the bottom of the plants and have put whats left of the rhubarb leaves underneath them hoping that they will do the same job as they did with the gooseberry sawfly.
Fingers crossed then... soon be ready... :)
We ate our first one yesterday and it was grub free. The others are no where near ready but they always throw one or two early ones.
