Prunifolium, curling leaves
My Blackhaw Viburnum has admittedly been through a lot, basically because I kept moving it. It's three years old but still only three feet tall. Last year and now this summer it is really starting to find itself and leaf out and grow. Though I've given it cause for stress, it really has continued to produce healthy leaves. This year the leaves are large and beautiful and is showing signs for a good summer of growth. It receives bright light all day but only 2 to 3 max at height of summer of full sunlight and at the height of the day, from around noon to three. My question: As long as I've had it the leaves have had various degrees and tendencies to curl. I read somewhere online that this might be lack of water. Does it need to be constantly wet? One more thing: at the end of last summer season there was a touch of powdery mildew on the leaves for the first time and now this spring I just found some black topped mushrooms growing in it's watering circle, or "drip line."
