Answer: Reclaiming a gravelled over area won't be easy, but once you've gotten your lush green lawn established, you'll think it was worth the effort. My concern about simply broadcasting seeds over the gravelled area is that each time you mow, you run the risk of pulling up rocks and shooting them out from the blades of the mower. That can be dangerous!
Quite often, people lay black plastic or woven weed barrier over the soil before spreading out gravel. This is to keep weeds from sprouting but also to keep the gravel from disappearing into the ground. If so, your reclaimation job will be easier. Dig down into the remaining gravel and see what you can find. If you find plastic or weed barrier, you should be able to pull or roll it up, gravel and all. If you find no barrier beneath the gravel, you may want to consider rototilling the area to bury as much of the rock as possible. After tilling the area, you can spread a couple of inches of topsoil and then rake the area smooth. This topsoil will become the base for your new lawn; a place for it to root. Rototilling will also ensure the area drains well.
Hope one of these suggestions works for you!
