g'day natty,

not a rose person or even a flower person, but maybe you could try the
milk recipe listed on our site on the remedies page.

also something to consider if the root system of a plant is healthy
then the plant will be healthy and mush more about to resist disease,
so look to drainage/watering of the plant (might be getting too wet),
probably alos available suitable nutrients, and above all and this is
all i know about roses they like a lot of sun or equivalent
substitute. also being in a well ventilated area could help.

just some ideas



snipped
With peace and brightest of blessings,

len
