Lemon tree dusty leaves
Hi, I confess to being a bit of a plant novice. I received a lemon tree for my birthday which I love, but many of the leaves have become 'torn' or have small holes. The leaves also have what appears to be dust spots on them.
I gently washed the leaves with a clean cloth but the dusty marks are still there. I contacted the nursery where it came from and they said it was water marks or just dirt - which I find hard to believe as the marks were there before and after. They said my plant is healthy and nothing wrong with it.
Any advice, or is it supposed to look like this and I'm just being silly?
Thanks so much!
