Did the search. Possible causes: high winds, herbicides, aphids or too much nitrogen. We have had some high winds but it has not effected my other plants. I live in the middle of town and have not noticed the neighbors using herbicides plus there is the other plants being fine thing. Aphids? I looked at the leaves and saw no bugs or eggs. Too much nitrogen? Maybe but having only one plant effected this way...hmmm.
I guess I will not fertilize it, but will spray it with Seven and with Ortho disease treatment stuff. Oh, and I will hold my breath so as not to breath on it so its little psyche isn't hurt. Maybe its just a "drama queen".
I should take a Master Gardener course. I wonder if there are any on line?
Long.
