Back around last veterans day I dug (rototilled) trenches on either side of my gravel driveway the whole length, and I wanted to drop RR ties or 8x8 landscape timbers but I didn't have $1000 that Menards wanted for the landscape timbers
my son asked ","what about telephone poles " which I hadn't thought about /but he had a buddy who had access to a pile of recently replaced ones that were still in great shape for free (said buddy is in the crew that replaced them) so that's what we went with. They stick up higher than I was wanting, even though they are half buried lengthwise/ but they will definitely serve my purpose of keeping the gravel IN the driveway and not wash out into the yard
and at the same time I have a spot in the yard on the front corner of the garage, that I have not been able to get grass to grow/ yet from the middle of the driveway to the end, somehow all the seed I spread in the yard ended up in, and had plenty of lush green grass sprouted in the driveway instead.... Hopefully the telephone poles will help keep the grass and gravel separated. Every time it would rain my seed would wash into the driveway. I wanted the tips of whatever border I went with to stick out even with the bottom edge of the mower deck, have the deck just scrape the border material... Maybe they'll settle in a little deeper. Once the t poles were in I brought in a load of gravel and filled it in, could have used a bit more .... And back filled the outside of the poles with the freshly pulverized dirt that I dug out.... And now, it's starting to sink/ especially the dirt on the outside of the poles. The poles haven't moved though from the height they were when dropped in.
