@thendrix I wonder why we have steep hills and expect top soil and maybe some netting to prevent washouts. A Terraced Farming style would allow for soil to be stabilized by grasses and shrubs. The benefits are not limited to washout protection but also the buildup of better quality soil that can absorb water. Steep slopes can make the velocity of water very high.
I remember one hill south of ATL that took nearly 2 decades to grow grass despite constant erosion control work. I'm not an Engineer but I wonder if anyone ever questioned the 70°- 65° angle of the hill being the problem. It fixed itself by eroding to a more shallow angle.
@thendrix It happens nearly everywhere down here. The only people I know who have known what to do were the heavy equipment operators.
It's good that the grass is growing and it should be a year or so before you see saplings. It sounds like a gully and shid fer if it isn't called that there.
@thendrix I was going from the general reclamation of earth by plants. Grasses and weeds start within year 1 and by year 3 there are shrubs growing and little saplings. If you want a good tree for that soil I would recommend finding some Sassafras seeds.
Sassafras attracts Monarch caterpillars, smells great, has a really good root system, loves most soils like swamp or clay and it's going to grow quickly. It's a native tree and will reproduce enough to be all in that area. The roots on those are perhaps the best way to stabilize the soil. They spread out and form a dense web like structure. It will keep that top soil from washing away. They also like to grow into tight packed groups. It's a cool tree.
