Ask the Experts A new question and answer section in the CSA Journal. Ask us any questions you may have about cymbidiums, paphiopedilums, phragmipediums or any other cool-growing orchids. We will answer your questions in the next issue of the Journal. Submit your questions by email to cymbidiumsocietyjournal@gmail.com Why do the leaves of my hybrid cymbidiums with Cym. devonianum in the background quickly turn brown at the tip? Hybrids of other species get the same regimen and remain green. Fig. 1 Cym. devonianum hybrid with brown leaf tips. Answer: Cymbidium devonianum and its hybrids are extremely sensitive to water quality. If the water you’re giving your plants has more than about 20 parts per million of dissolved, solids, then it’s possible that the leaves will turn brown at the tips. This is especially true if the dissolved solids have a significant amount of sodium. There are several ways this can be improved. There is a varying tolerance to total dissolved solids from plant to plant, so when purchasing plants from among a large selection of Cymbidium devonianum plants, look for the one with little or no browning of the leaf tips. Also, for any given plant, this can be reduced over time by using higher quality water. Rain water could be saved and used for these sensitive plants, or if one has a reverse osmosis system for drinking water, that water could also be used for these plants. These plants should also be given less fertilizer than plants that have no tendency to leaf tip browning. 13
