The rose of sharon and the hackberry should be fine. Not so sure about the crepe myrtles, though. I have a little trouble with them here, but I think it's the soil where I tried to plant them. I am a myrtle murderer, three times. *Sigh*
Even so, I have one more that finally looked good at the end of last summer. If I lose it, I give up.
Hoping for y'all a much better and drought free summer, Marylyn.
