I, too, have heard the advice not to get water on rose leaves, but I
have never been able to convince the rain clouds to agree with me.

It's not an absolute, obviously there is nothing you can do about rain. The
problem is that many roses develop fungus and mold because of wet leaves,
especially rust, and black powdery mold. Roses that get watered from a
pop-up sprinkler often have rust on every leaf.
