Looking for some advice. Having just completed some more excavation around the house we are left with a tall earth bank, very claylike.
I would like to plant something in it that will make it maintenance free. I don't want to have to strim it as it's too high in places to make that practical and also it's big. Around 25 meters in length and 3 - 4 meters tall in places.
Ideally it would be something cheap, not require a geotextile covering of the bank and if it served to stabilise the soil too that would be good. The bank collapsed in the steeper areas during the recent rain, which is why I've made it a shallower slope.
Looking forward to hearing your suggestions!
