Hi all I planted Falstaff and Winchester cathedral in containers 2016 and last year had great blooms esp WC However both were really affected first by black spot and than powdery mildew to my extreme chagrin I have them nicely spaced and feed them with rose fertilizer maybe 2 or 3 times last spring and summer
We have a bad winter this time and they are both outside unprotected
What was I doing wrong?
Hopefully they will return this spring and this time I have decided to just let them be and not use any fungicide or insecticides !
