Rust colour spots on pear leaves


This tree has had these rust colour spots for as long as I remember. What are they and can I do something to remove them?


Sadly, you are one of many Toronto gardeners who have contacted us about rust spots on pear leaves.

This is a problem that has been increasing over the last 10 years. Here is a comprehensive response we provided to another inquirer: Pear Rust

Unfortunately, as you will see, the prognosis is not great. It seems as though the problem is spreading very slowly on your tree, so I hope you get a few more years out of it!
