So my wife and I are new to all this and knowingly made a mistake which we are now forced to deal with. We had a rock driveway made and was originally told to use large rocks initially and finish with smaller rocks later once the large rocks are pressed down. Well now we are left with a large weeds/grass problem infesting our driveway. What is the best solution for this? I’ve tried to spray weed killer as well as pull weeds from roots, but getting to the roots with the killer is a problem due to them being under large rocks. Is removing the rocks and starting over the best option? We are obviously trying to avoid large costs…
