Ofm, just checking to ask you if you did mix the rock/gravel/whatever INTO the soil such that the rock is evenly distributed into the soil and the rock becomes part of your soil mixture. I ask only because you mentioned earlier about raking rocks into the soil which is not the same. The placing of the dressing of rock/grit on top of the soil serves to prevent the leaves from possible rot as it helps to delay the loss of moisture. The mixing thoroughly of rock in the soil helps with drainage of water that may sit in the soil causing root rot.
