When a certain stems of Dendrobium become almost leafless, that indicates that the stems would give no more flowers. Such stems are called ‘Exhuasted’. They look ugly on the plant. So it is better to remove them with a sharp secateurs. Instead of discarding such stems it is advisable to put those in an elongated planter in which a thick layer of charcoal and brick pieces is laid.
Keep the brickbats and charcoal moist by spraying water on them. This will encourage the exhausted stems to give new plantlets. Such stems, even if retained on the plant can give new plantlets, but the exhausted stems look bad on a healthy Dendrobium plant. A single exhausted stem can give rise to one to three plantlets. When the plantlets start getting healthy, spongy white roots with active green tips, they can be planted in separate planters. Dendrobium orchids are epiphytic and cannot survive in soil. They grow best in charcoal, brickbats accompanied with a few pieces of coco chips (coconut skin pieces chopped to small size). Here is a video showing the process.
