Agree, too much water, I have them growing wild along my fence and in the
backyard, they never get any water from me and I'm in Eastern Washington
state where it is very dry and hot during the summer.

Well, what is one suppose to do when they start to wilt without water for a day
or two? Thats what happens to mine. I live in NYC, and we have been getting a
lot of rain this summer. mine are in pots out on the patio. Should they be
brought in for the fall and winter?
