Hi, I seem to have developed a white mould like growth on the base of two of my Acer trees, they both grow in pots and are well established. Does anyone know if this is harmful? I would hate to lose them. Thanks
You sure it's mould and not scale insect - my mature acers suffer from this invasion. I wash them off with cotton wool and water.
My acer was doing very well indeed. Then i left it in the convervatory where a month back it seemed to love..and now..with a weeks heat..the leaves literally are burnt - white. Have planted it out into the garden and hope for the best. All white/black leaves.
