Hello. I planted a Hamamelis x intermedia 'Arnold Promise' witch hazel in my backyard 4 years ago. This year it did not bloom as usual, even though it tried a couple of times (I can only imagine the odd weather had something to do with that), then I noticed the brown spots on some of the lower leaves. I thought perhaps I was not giving it enough water and it seemed like the browning slowed with more watering. But now I find even more browning on new leaves. I do not see any bugs on the underside of the leaves even though one leaf is riddled with little holes. Any ideas and suggestions will be greatly appreciated. Thank you. Theresa Holte
