My lemon tree
I live in Cleveland Ohio so I bring my lemon tree almost a year old indoors for the winter. It is strong and healthy. My question is there seems to be a sticky substance on the leaves. I don't know what it is or if its harmful. In a week or so I'll be bringing it back outdoors for the summer. Will it stay healthy even with this sticky stuff on the leaves? Or should I try to remove it, if so how? Thank you in advance Wanda

This is likely Honeydew; the secretions from pests.
Treat the tree with Neem Oil.
