Question From: Brampton, Ontario, Canada
Q: Some apples are indented, with pimples, hollow and black spots on the inside,
A: Victoria, I am not well versed in apple issues as I do not grow them. I suggest you contact the Master Gardeners in Canada to find a horticulturist near you. It would be helpful if you would have the varieties of apple trees available. Best And Happy Yardening, Nancy.
