pH and watering
I was just reading about using coffee in gardens and it's brought about a question.
To water my Phals and my Dend I filter the water using the Clear2o pitcher. I live in a city which tends to LOAD the water with chlorine. I don't drink the straight tap and I don't expect my plants to.
According to the book, "Orchid Growing Basics" by Dr. Gustav Schoser pub. 1993 orchids ultimately like a pH of 5-5.5 when watering. My pH is 8 with and without Jack's Classic 30-10-10 Orchid fertilizer. It also states in the book that soaking untreated peat moss in water for a few minutes can help acidify the water, but what about used coffee grounds? Would I be able to use that too?
