We were lucky at the end of August -- lots of folks around us didn't get the welcome relief of the heavy thunderstorms that added over 2 inches of rain to our garden. The state drought response team has just raised drought levels to severe in SC - here in the Upstate (roughly the expanse in SC between Atlanta and Charlotte, NC), it's particularly bad. Our garden is a low-water use garden (except for the pampered vegetables and the much less pampered container plants), although they do make do with hand-watering and don't have soaker hoses that run for hours on them. A neighboring county is calling for water conservation, and only watering lawns (!) before 5 am. In my opinion, it's a bit much to water lawns at all, but we're not lawn people. We have brown patches that have developed in our Zoysia lawn areas.
But we're still monitoring plants that have been planted in the last few years, and watering them regularly. Anything that's been planted in the last three years needs water, when it's so exceptionally dry. Deciduous azaleas, Itea, Joe-Pye weed, Frasier magnolia --these are all thin-leaved natives used to regular rainfall, ditto for some of the forest understory species such as dogwood and redbud.
