No problem, Rick (RCanada). I should remember to put a simple answer at the top of the post, and then put "If you're interested ..." before I go on and on and on.
That way there's a clear point to start hitting "Page Down".
So many things are different from garden to garden, and gardener to gardener, that I have the belief that ANY simple answer is wrong for someone, somewhere.
Of course, "You COULD do hours or days of research before guessing what to try next" is advice that 70-80% of people have NO desire to follow! (But I love doing that. I can do research without kneeling or even bending over!)
