Hi! I have a peach tree that I estimate is ~10 years old. It is maybe in poor health, but I am not an expert and I am wondering if you could help me decide whether to contact an arborist for in-person assistance. The tree bloomed beautifully this year but almost all the flowers were lost during the freeze in late April so it only has two peaches currently growing on the tree. It has had two periods of yellowing and dropping leaves this summer. The leaves did not appear to indicate either over- or under-watering (it is on a drip and it runs 6 mins every other day, which is in line with what the previous owners of our house said they did). After the first time it dropped leaves, I fertilized using Espoma Tree-Tone (6-3-2). It then dropped leaves again a few weeks later. I have also noticed these marks on the trunk (photo attached). We have a few Japanese beetles, but not so many that I can't make a dent in their numbers by removing them by hand. Any guidance about how much I should worry would be super helpful!
