The 4 Stans I have were recently repotted in plastic mesh baskets in which I cut out some of the plastic to make openings bigger and others are in wire baskets whose diameters are different sizes but have about 2'' openings. A Coryanthes bit the dust at still a young plant,my fault surely,but I'll try again. Love the look of blooms hanging over a pot edge or under neath. And what a fragrance!
