Hello from northwest Wyoming. I am very new to orchids. I just bought three Phal's at Walmart over the weekend and I can't stop looking at them, thinking about them and reading many hours of the day about them. They came in clear plastic 4" pots with a bark medium. I watered them according to instructions I read in an ebook The Orchid Whisperer by Bruce Rogers. Now I weigh them each morning to better help me know when to water them again. I also ordered some fertilizer from rePotme.com and intend to follow a fertilizing schedule of weekly weakly. I have well water and it tested with pH 8.4 and alkalinity of 180. From what I read this is not good for facilitating the plants' uptake of nutrients. I also tested Walmart's bulk drinking water they sell and it tested pH 6.8 and alkalinity of 40. This is better but still not best so today I'm going to try to find some citric acid to bring down the pH. Here is the link that has helped me understand the importance of the water quality: www.repotme.com/orchid-fertilizer/Part2_WaterQuality.pdf Looking forward to reading everyone's posts and continuing to learn about these beautiful plants.
