I just re-planted some Iron Cross Oxalis today (they were stacked pretty high in their little 6 inch pot). I started putting them point up/roots down but it was the end of the day and I was tired. I tossed the last 3/4 into the new bigger pot and covered them with dirt. I'm not sure how they fell - point up or point down or point heading west.
I will let you know how they fare.
