Hi there! I’m in my first spring/summer in my new home and am learning to care for the outdoor plants. There’s a darling little lilac bush that is having a tough time and I’m struggling to figure out why. Its leaves are curled and getting a bit crunchy. It’s in a part shade spot. The small trees/other lilac bushes around it appear happy and healthy. It sits near the top of an incline/isn’t sitting in water. I need to have a soil test completed, but it overall seems a bit sandy and water doesn’t sit. I don’t notice any visible pest damage to the leaves. And, we’ve had some good rains that haven’t perked it up. Is there any chance it’s overwatered somehow? I’m feeling pretty stumped, but I’m also very new to outdoor plants. I’ve included a “close up” of the leaves. Thank you so much for any thoughts you may have— I sure appreciate it!
