Recently I have decided to take the Ph of the soils out of curiosity. To my amazment most of my vft's soil had a ph of around 6-6.8 which is pretty neutral. I've heard that they'll do best in soil that is around 4.5-5.5, so does it really matter? My plants seem perfectly happy with their soil and are growing quite well.
Does anyone have any tips on how to keep the medium acidic?
