Why would my old-fashion lilac that I have had for over 50 years change into something different?
The leaves have become larger and shaped differently. Even the new shoots coming up are like that. I have never seen anything like it before. How could this happen?
I will take a picture when the weather warms up and send it to you. It is really weird.
It is difficult to say if there is an issue with your Lilac without seeing images.
Leaf changes could be due to age, growing conditions, pests or disease.
You can upload some images for us to look at.
