Could someone tell me the household mix for treating black spot on roses? Is one of the ingredients baking or washing soda?

Never heard of a DIY treatment. Use Roseclear and follow above advice.

Isn't it one part milk to two parts water? Any kind of milk. I read the formula on this site and it has worked for me so far.

Heard of that come to think about it. I seem to remember it has to be full cream milk?

Fungicides containing myclobutanil -- I also cut off any leaves that are showing signs and burn them - also remove any stems that had it when pruning.
