Salty soil groundcover?
I have what may be an unusual situation.
I am on a well and septic tank, but because the leach bed failed several years before I moved in, an aerobic septic system was installed. I have been told that you can not discharge water softener salt into one of these systems. So the softener has been discharging at the top of a north facing slope of a ravine beside my house.
I had noticed and been perplexed by the lack of growth in this area until I realized we have been salting the hill for years now. The large trees are still present so it is shady but not much undergrowth. There is a lot of exposed soil.
Assuming for now I can not move this discharge point. I am looking for salt tolerant plants to put in this spot. I have heard Red Buckeyes and Kentucky Coffeebean Trees are salt tolerant. But I do not know of any ground covers I can use. My first concern is erosion control. Any ideas are welcome.
