This is the eastern end of what was long ago a bed on the north side of the parking area west of the drive.
I can recall mowing right next to it back in 1999 and at that time I could see two layers. And the bed was quite overgrown then, with trees easily 15' tall.
As I study this area for permaculture purposes, I decided to pull out the treated wood of the bed border and discovered there are three layers, not just two. So there has been considerable build up of soild around it. Here you can almost see the middle layer, though it was hidden most places.
On the left is a multi-trunked mulberry that I think needs to come out so that the sassafrass in the middle back will thrive. Also to minimize berry droppings on cars.
The two in front right are oaks and one of them should come out. Both have parts of the old wire bed border thing that I may have to leave, or just cut away.
In addition, this end of the bed has a large poison ivy vine population as well as a bunch of young bush honeysuckle.
Also several yucca. No sure if this is the best place for them, now that the soil is so rich here.
