My allotment has a lot of flint stone (UK, Bucks area). I am preparing the beds for the first time, and have been reducing the amount of stone as much as possible by raking and removing stones as I can. I have been told that there is a virtually limitless amount of stone further down that rises up over winter (I guess when the soil is wet enough, the larger stone rises to the surface?).
How much truth is there in the rumour that they keep resurfacing?
Is there any where to reduce or stop them rising up? If I were to dig down a good way and put a weed membrane would it stop the stones, or is it likely to cause issues with the soil structure/roots etc?
Or do I need to just keep pulling stones out, and expect to repeat the exercise every year?
