Acidity of Azalea soil

[isaaquitas]

Hello everybody,

I have read that the acidity of the Kanuma will decrease over time. Last May/June, I can't remember, I repotted my azalea into pure kanuma. I am worried that this acidity will decrease. Are there any ways to increase this, or is it not true that acidity decreases? I live in Europe, so there are certain products that I am unable to buy.

If you are watering with water from a municipal water source, the water treatment plants must legally keep the city water more alkaline because acidic water will cause the lead from old lead pipes and lead pipe solder to leech into tap water. Over time this will cause soil to become more alkaline. Because of this, rain water and well water (depending on the ph of your ground water) are generally better than city water. To keep the pH of your soil higher, you can fertilize using an acidic ertilizer. I think a lot of folks use Holly-tone which is a good organic fertilize for acid loving plants, but works better in refinement stages (and best if put into tea bags as it will muck up your soil pretty quickly if you use it often), as it won't give you crazy growth. If you are talking trees in refinement you can supplement with a liquid fert to boost the nutrients you want and the added Holly-tone will keep the pH lower.

I'm sure others with more knowledge will chime in, but this is where I'm at in the learning curve myself.
