New plants are usually produced by dividing larger mature plants. The best time to do this is in early spring. When dividing your plant make sure you have 4/5 healthy pseudobulbs and place in the pot. Remove all dead roots and place the plant in the centre of the pot and add fresh re-potting mix. Water well and leave for a few weeks before watering again. Make sure all cutting tools are clean and sterilised before and after use.
