Hi Annette, the pseudobulbs need to remain in a moist but not wet medium for them to sprout new roots and a new growth from the dormant buds. My suggestion would be to soak some sphagnum moss in water, squeeze out the excess water until the moss feels damp, but you cannot squeeze out any more water. Now wrap this around the base of the pseudobulbs and then place them in a plastic pot. Gently mist every other day and put the entire assembly in a warm humid place with bright diffused light. The amount of moss you use should be just sufficient to wrap around the bulbs, say about half a fistful. Anymore and it will stay wetter and not allow it to dry up in a day or two. Catts are sturdy, this should do the trick.
