Over the weekend my aunt gave me 4 bare root Cattleya plants. Each plant has 3-4 pseudobulbs. I think they are all the same kind of Cattleya, but I'm not positive (there were no tags). My question is can I pot all 4 Cattleyas in the same pot? 2 plants in the same pot? Or am I better off keeping each on in it's own pot? Also, how coarse should the potting media be? Thanks!
