Results Of pH Experiment After One Year
A friend of mine has kept a careful photographic record of one year since changing the pH of his water. It is such a dramatic example of changing one variable, to see that it really was the pH that was the problem for these weak trees. Weakness resulted in susceptibility to needle cast and yellowing.
There are two different trees here, a pine and a yew. The fronts are different in the photos but they are the same tree.
He writes: ‘The first pic is from 3/18/2015, the second is from 3/12/2017. Our well runs a pH of 8.8 to 9.0, I try for a 6.4 on the treated water, using muriatic acid. I batch treat with a 500 gallon tank. I started treating the water in Jan. 2016.’
Pine, 3/18/2015. Well water pH was 8.8 to 9 at this time. This is highly alkaline, very few trees grow well in it.
Same pine, 3/12/2017. After watering with altered pH of 6.4 for one year, which started in Jan. 2016. With this pH one can keep most plants very happy, and able to take up nutrients.
Same schedule, pH change, and photographic dates as the pine was followed with this yew. 2015 photo.
