Err... I don't know if thanking for the comments or apologising for having said something inappropriate or stupid...
My question was because I am not sure if they are gonna end up being aerial or going into the soil. And there is my worry, if they are going towards the soil, which seems to be the case of two of them, should I do anything as moving the bits of bark out and so on to "make space" or just let them "excavate" themselves?
