| A rule of thunb, especially with Dendrobiums, is to pot small. That 3" pot is more than big enough. Orchids assist in the drying out of the pot by their up take of water. A 5" pot would be beyond the ability of this plant to have much effect on the drying process, and you would run the risk of rotting the roots. I would repot this plant when it grows over the side of the pot, and only into a slightly larger pot. Cynthia, Prescott, AZ |
