| For most of the common Dendrobiums, don't let the plant dry out completely while it is growing. Once the new growth stops producing new leaves, you can give the plant a wet/dry cycle. During winter, the length of time the plant should be left dry before watering should be several days to a week. But once new growth starts again, water well. There are some species of Dens that should never be allowed to dry out, but you don't usually find these at common retail outlets. If you should get a Dendrobium with a species name on it, you will have to research that particular species. I just bought a Den. crepideferum from Home Depot, so it does happen. This one gets wet/dry during winter, but not the extra days dry. A few drops of Super Thrive in your fertilizer water would probably be good for your plants. Cynthia |
