Have friend in Wimberly, TX. Says everyone has holding tanks where by they collect the rain water.
Yes....lots of cisterns and rain barrels in Wimberley (one of my very FAVE TX towns) and other towns, in Texas.
My plum tree is looking like a great crop, so far. I hope we don’t get any super strong winds, before the end of May. That’s when I harvest/can my plums, for jam.
