Dwarf Pear Tree
I have had a dwarf pear tree planted in a large tub for three years. Each year it has what looks like scale insect on the leaves and the leaves end up dying. This year I have sprayed the leaves with Bug Clear when the leaves started to appear and then again when they were fully out but I still have this infestation and it seems to start at the top and be working its way down the tree. The tree seems healthy with plenty of flowers and now the pears are beginning to form, but what can I do to stop this happening to the leaves and will it damage the tree at all? I would very much appreciate some help.
