>> Generally, the places where those roses were found got sufficient winter rains to keep the plants alive. I am trying to mimic that cycle.
Great plan, working WITH what the plant evolved for (or at least what it has survived recently!)
I also like your idea of trying out what sounds like it makes sense, and learning from the results. I think that's the only way we all learn new things. Just repeating the conventional wisdom without testing alternatives doesn't discover anything new, and it barely even tests the conventional wisdom.
