How Do You Rehydrate Dendrobium Orchids?
Dendrobiums are in the epiphytic group of orchid plants that use their roots to draw moisture and nutrients from the ambient air. The water and nutrients are then stored for use in a pseudobulb that makes up the lower potion of the stem. Dendrobiums are grown in a very coarse and fast draining potting medium. High ambient humidity between 50 and 80 percent is needed to keep dendrobium orchids healthy. The coarse bark used can also become resistant to holding moisture as it ages and breaks down leading to drought conditions for the orchid. Rehydrating a dendrobium requires frequent deep watering and fresh potting medium to ensure the best chance of rejuvenation. Water your dehydrated dendrobium well when you notice it is overly dry. Hold the pot under a slow running stream of tepid, not cool, water from a faucet. Drench all of the medium and roots and allow the excess to drain away. Repeat this process the following day or two until you can get the orchid repotted into new medium. Choos
