Leaves curling on a Japanese Maple
Hi, The leaves have recently begun to curl on my Japanese maple. I don't see any spots or holes indicating that it might be a fungus or insect. I read online that these trees are susceptible to Verticillium but the leaves are not turning yellow. It also looks like many of the smaller, new branches are dead as well. I had not been watering it because it was raining so often, but the last week or so has been warmer so I did water it. I included a photo of the trunk as well because it has some irregularities in the bark and I'm not sure what to make of them. Thank you.
