A class about creating desert rain gardens will be offered Oct. 8 at The Nature Conservancy, 1510 E. Fort Lowell Road. The workshop will introduce participants to the concept of creating a water-thrifty landscape that relies on seasonal rainfall and rainwater harvesting techniques, rather than supplemental irrigation and potable water. The class will take place from 9 to 11 a.m. For more information, or to register, call the SmartScape office at 626-5161.
