I am wondering how to harden a particular soft edge along a driveway so that I can drive on it without damaging the lawn.
Last year I installed a secondary approach by building up my lawn with the recommended soil sand mix and most of it setup great and I am able to drive on it even right after a rain or snow melt with a full size pickup and trailer. There is however about a 10ft section right off my driveway that is softer than really the rest of my lawn and especially the rest of the secondary approach (which is lawn).. by August it is hard as a rock with the dry weather.. but the first half of the year it is soft.
The problem existed before I installed the secondary approach but thought I was addressing it by sloping it off the driveway at an even angle building up the section with the same type of soil (even though I dug it up a bit and mixed it in) I used to build up the secondary approach.. but it did not help.
I know I could put down some crush gravel and just let it be gravel but I both want to keep it lawn as well as not 'move' the problem. I've used Geoblock in trail building but its expensive and not always practical and not sure how it does with driving on.
I also read that sanding probably wouldn't help and I already installed drainage ditches or slopes on both sides (there is a ditch between the hardened lawn and the trees and a general slope downward side of the hardened lawn in this picture).. what else can I do?
