Hello all,

I am going to spray copper on my peach tree but I don't know what temp it must be to be able to do it. I am in Ontario, Canada. I was advised to spray copper as my tree experienced an infection last year (though the fruit were fine). Also should I spray my cherry tree??

Thanks alot,

Ravi
