The present is a free-growing species if the plant is in good health. It begins to grow when the flowering is over, and this is the best time for repotting if the plant requires it; but care must be taken not to over pot it, as this is dangerous in some cases, especially if the soil should get into a bad state, for then the roots go rotten, and the plant becomes sickly. If this should happen, shake away all the soil from the roots and wash them well, afterwards repotting the plant in as small a pot as the roots will allow; the fresh roots will then begin to work about the new soil. Good drainage must always be given; and the plant must be well elevated above the rim of the pot. The most suitable potting material is good rough fibrous peat mixed with lumps of charcoal, which will keep the soil open, and allow the water to pass off freely. Over watering is dangerous, but the plants require to be kept moderately moist at the roots during the growing season. To avoid risk from excess of water, the pots should be three parts full of drainage material. When the growth is completed, give sufficient water to keep the stems plump until they show signs of flowering; then give a little once or twice a week, the quantity and frequency of the application depending mainly on the nature of the potting material; if it be rough and porous, the plant will require it, and a slight syringing over the soil and among the roots during a warm day, will also be beneficial. We grow our plants at the cool end of the East Indian house, giving them plenty of light, and no more shade than is necessary to keep the foliage from burning. Light is the grand agent in ripening the stems; and it is thorough ripeness which induces them to make vigorous growth, and to develope their flowers freely. Propagation is effected by dividing the stems just as they begin to start into growth, leaving two or three old bulbs at the back of the new one. It is the better plan to cut them a short time before they are parted; and this should be done with great care. After dividing, place them each in a small pot, with good drainage, and similar potting material to that previously recommended. They thrive well in sphagnum moss, but we prefer the peat.
