Hi Brabantia, interesting to hear that you have the same plant, it would be interesting to see how it compares when in bloom. Rainwater is indeed slightly acidic and that is what I primarily use.Beautiful flowering. I have also the same clone from Assendorfer.
When I fertilize this plant I'm always a bit puzzled. I know that in nature papiopedilum delenatii thrives on a slightly acidic substrate. So I'm wondering whether I can fertilize it with a fertilizer containing calcium and magnesium such as Rain Mix Akerne or use a fertilizer containing less Ca and Mg such as 15-5-15 Cal Mag? The latter being very acidic, I still have to add 8% tap water to adjust the pH to a value of 6. Would a fertilizer without Ca and Mg be more suitable? Your opinion please. Thank you in advance for your answers.
