Someone suggested me mixing 1TSP baking soda in 1 gallon of water and spray
the roses with it in cool season. Apparently it doesn't work in summer due
to heat. Now is good. I tried that last year, it seems to be working. But
it is not an immediate solution. You need to keep doing for several weeks
which I haven't.

Over the spring I had borrowed an Organic Rose book that I gave back and
can't find.

It had a recipe for Sulphur powder for Black Spot.

Day before yesterday was the first day I'd seen my roses in bright light
for, what, a week? And they are covered. I'd got some powdered sulphur,
but
now I can't remember what I was supposed to do with it...

tia!
