In the garden of Einar I have some unusual, old and very abandoned plants. There are Sycamore trees more than six feet tall, Fuschias in full bloom and rhubarb the width of my wrist. I’ve always wondered what the spiky bushes were all along the wall; maybe they are gooseberries I thought. I take a closer look and realise one of them has been completely stripped bare of leaves leaving naked stems and laughably ineffective spines. It’s an attack by the Common Gooseberry Sawfly and its larvae are devouring my Gooseberry bushes like a Biblical plague of Egypt.
