How do I treat black spot on my silver birch sapling?
Cornwall, United Kingdom
I am a relatively new gardener, having lived in a flat most of my life.At last I have a garden.It has extremely sandy soil and faces southwest. Last year I planted a silver birch sapling. It has grown a lot but seems to have black spot (can trees get black spot?)as quite a few leaves have turned yellow with black spots. Please can anyone advise what I should do about it?
