/diy/ - Do It Yourself

>>1388275
You don't really have to do anything. That area is surrounded by forest and it isn't even really ruined, it's just cut down. I have first-hand witnessed some old agricultural land reforesting and it's surprisingly fast process, and that wasn't even purposely replanted like yours.
Next year it's filled with tall grass, the year after that it's full of nettles, raspberry bush and even some willow saplings. The year or two or three after that comes the poplars.
10-15 years and it's a young living forest.
