Phrag water question
At the recent Redlands International Orchid Festival, I challenged
myself by purchasing two Phragmipediums: Phrag. St. Peter and Phrag. Don Wimber. Now, I've been growing orchids for maybe four years, and I'm pretty good at keeping Phals, Dens, and Catts alive (and even getting them to bloom once in a while). Living in Broward County Florida, this doesn't take too much work. I am lucky enough to be able to keep my orchids outside in the elements, and most of my battles involve finding just the right amount of light in my back patio (or trying to squeeze in one more plant into "just the right spot"). I've heard that the Phrags, especially, like ultra-pure water. This is the rainy season, and lately we've been getting almost too much rain, so clean water is really not a problem at present, but my question is this: Will supplementing the not-always-so-regular rainfall with water from the Pembroke Pines public water supply damage these apparently delicate plants? The water is "moderately hard" at 3 grains/gallon, and the PH is slightly alkaline (8.8 - 9.4). Sodium, calcium, and traces of magnesium are to be found in the water samples. And, while I'm thinking of it, what's "just the right spot" for these plants as far as light goes? Can they tolerate direct sunlight (filtered through a mosquito screen) for any period of time? Should I put them with my Phals (which get only a tiny amount of direct sun), my Paphs (which get no direct sunlight at all), or my Catts (which get quite a bit of direct sun)? Should I be worried about the high summer temperatures? Will the 90's of South Florida end up killing these plants? Thanks for any comments! |

Phrag water question

Should I be worried about the high summer temperatures? Will the 90's of South Florida end up killing these plants? I grew Phrags in New Orleans for almost 10 years until I moved to Longview, TX last fall. The weather there is similar to yours, though we got a bit cooler in the winter. The same light you give the Paphs (or a bit more) should be fine. As for temps, they do like cooler temperatures than Phaps, usually 80 during the day and 60's at night if possible. You could add as much as 10 degrees to both, and the should still be ok as long as they're kept moist and have good air circulation. They will also bloom and thrive much better if given a winter "cooling off" of a few months with temps in the 50's at night and 60's-low 70's during the day. As for water, I found it best for the plants if they have a neutral to slightly acidic pH of 6.0-7.0. I add a bit of vinegar to my Phrags water supply to drop the pH to the proper level. I also have a Don Wimber and it's flowered a number of times for me in the past few years. Bob C. http://vchilder.home.netcom.com |
