Per the September Drought Indicators Report (link below), it's dry and expected to stay that way...
The AJC reports that we are on a level-one drought response holding pattern due to low rain levels. We should limit outdoor watering to the hours of 4pm - 10am. According to the AJC, "One inch of rain or water every 7 to 10 days is all your plants need."
