Tiffany,
It gets sun from mid-morning (10:00 to 4:30).
As far as watering, 1x a week they get apprx. 1 gallon of water and 90% of it goes into the ground. I have a ring around them to avoid run-off, but no mulch. It hardly ever rains here in Southern California between May and October and daytime temps here range from 80* - 95*.
Thanks,
Mike
