They don't like fertilizer either just to be grown in a mix of peat moss (not coco peat) and coarse sand. Sitting them in shallow trays of rain water(more water in summer, less in winter). You need to divide them or else they'll bust the pot as the grow across the pot filling it quickly. Having them in to big a pot just leaves to much wet peat moss around them and they can rot esp. during winter when there dormant.
