QuestionWe have a Den. Salaya Fancy that is growing off shoots from the main stems. The off shoots have roots and now one of the off shoots is producing yet another shoot. What do we do? Can we cut them off just below the roots and pot - or do we leave them? The shoots are growing almost perpendicular to the main stems. It has never flowered after the first blooming- we water once weekly and fertilize regularly.
AnswerDeb, it sounds as if the new shoots are growing from a node (ie joint) in the cane. If so, the new plants are called keikis ane can be separated from the cane once they have roots. This can usually be done by gently and carefully twisting the ponit of attechment to the main cane. Be careful to to damage the roots at that juncture. Once you sesparte the keiki, you may pot it in a small pot just large enough to accomodate the roots. As long as the roots have green growing tips you can keep the potting mix moist.
Often keikis form in the place of flowers because a plant is not receiving sufficient light to produce flowering hormones. You can summer the plant out as long as the night temperature stays above 50 degrees. Gradually (over a period of weeks) move the plant to higher and higher light levels until it is nearly in full sunlight. The canes should be a light green or yellow green to indicate sufficient light. Dendrobiums need a rest period when not in active growth. When there is new growth, water and feed heavily. When the new growth matures, cease watering and mist the plant in the mornings twice a week. Usually these plants go into dormancy in the fall and, if rested, should flower in mid-late winter. Mine came into flower in a west window where it gets lots of afternoon sunlight and warmth. Flowering began in March, finished flowering in May, at which time I placed it outside and it now has a vigorous new growth.
