I was told by my landscape designer that chanticleer pears have started having a problem with disease in the Toronto area. This was told to me August 2014. Now I live in Cobourg and would like to put them in my landscape. Have you heard anything at all about this problem?
Thank you for contacting the Toronto Master Gardeners.
The disease your landscape designer is referring to is Pear Trellis Rust. This is a well known disease of ornamental and fruit pear trees that has spread to Toronto and within Ontario only since 2007.
