Hey all -

Do you know of any good *pet friendly* treatments for 'black spot'?

Blackspot is a rare visitor to my SoCal area. But rust and mildew can be real issues.

After almost 3 decades, and having had sprays trigger seizures in a dog we loved, our solution is . . .

We can tolerate a passing outbreak of disease, but a rose that is troubled most of the time can be replaced by one that does not have that issue.

I spray with sulphur or the Cornell mix. Not perfect, but it works pretty well for those that need it. Almost everything here will get BS eventually, but this year it's early before the first flush.

Thank you! The Cornell mix looks perfect. I have a pup that is very curious so cannot be trusted around most flowering plants!

I think Copper Sulfate would be OK too- I use it and it has never hurt my pets, and we use it in our pond. It s safe for fish at the recommended dose.

Black spot is not rare in California. I had one rose a Grandmothers Hat, it had black spot and we had rain for about 3 weeks on/off, that was enough to spread the black spot around. I finally got fed up and pruned all the leaves down to just 2 sticks, now they are coming up BS free. I don't like to spray but if this persists, I will do a better job of selecting rose next time.
