Ok having only grown potatoes in bags before, I have a (probably daft) question. When using the trench method, do I pop the potato at bottom of the trench, say a foot deep, then fill trench completely leaving surface of bed smooth, or do I just chuck a bit of soil back into trench at this point leaving what will look like a shallow trench? I know to earth up etc, but if the potato's at the bottom of a trench wont the rain fill the trench and rot it before it has chance to grow and need earthing up?
Help!!
