I thought about that. Planting at an angle would be OK if there is growth on the other side. Right now all the shoots are on the moustache side and planting on a slant means they will have to grow around the current trunk. My experience in the past doing it that way has not looked great. I am taking a wait and see tactics on Borat.
If Borat continues to be this way, I may make a pot that simulates a pond bank where the moustache roots are in the soil on the bank side. If remains dead, the other side will be carved out. A big hollow near the base and taper to the top is in my mind.
