Remove Oleanders with stump grinder or ???
I have a 150' row of mature Oleanders that are dying from leaf scorch that separate my Southern California house from a freeway. I want to replace them with something that grows very fast and thick with full sun and minimal watering. I think I've settled on Hopseed bush (Dodonaea Viscosa) but I'm concerned on how I should remove and prep the area. Most companies I've contacted say they'll use stump grinders. I'm concerned that this won't remove enough of the root and that the new plantings will have a poor growth environment. Should I push to find a backhoe or other means of doing this, or is the grinder a satisfactory method? Any better choices than Dodonaea? Any thoughts on this project are really appreciated!
