What type of fertile substrate is it? How much did you mix it? Maybe a picture would be good. Most likely you won't, if it's only a small spot you can just put a little more gravel on top.I did something stupid while placing the new root and rearranging some stones, by mistake i mixed the fertile substrate with the gravel. Do I need to replace the entire substrate+the gravel?
