I planted three magnolias at the start of the summer and two are growing really well. One is not. It has hardly grown and certain leaves are wrinkling and turning brown. It does look like the affected leaves are being eaten. Only the leaves at the top of the plant are being targeted. The variety is Magnolia liliiflora Nigra. Two local garden centres believe that it is either caterpillars or slugs causing the damage. I've would appreciate your thoughts.
