John there are acids you can add to lower the Ph. It depends on the Ph of your water source. If your water is alkaline you may need to add acids through your water system all the time or you can just add low amounts of acidic fertilizer with each watering. If your water is acidic or neutral just water the mix and the Ph will fall by itself. You can cut the mix with raw peatmoss which is often 3-4Ph or make a special mix of your own with peat and pinebark, that's what we do around here in our nurseries. I assume you checked the Pro mix Ph?.
Whenever any bagged mix is made at the factory its buffered to 6.2Ph. This number falls the minute the bale leaves the factory and will fall into the 5 range within 6 months to a year just by sitting in storage. Don't ever go by what the label says. I bought a skid of freshly baled mix of 6.2 that tested out at 5.3 a month after delivery...Bob.

I need to reduce the pH of promix for some of the woodland species of plants that I want to grow this year. It is my understanding that there is a buffering agent for maintaining the pH in the promix. I am looking for a product that I can add to the media to reduce the pH and keep it lower consistently. Could any of you folks give me direction regarding this matter? Thanks, John DelvasMaple, WI.
