Do you happen to have a link that explains how to do so?
When i was reading about acidifing soil for growing blueberries, i did not find a method with a reasonable permanence/cost ratio.
Thank you.
Fixing PH is often done with minerals or ashes depending on what's already there and what's missing. It's unique to each location and soil needs. I've never seen a permanent method for fixing PH as it tends to naturalize back towards what is local for that area. However, the more biodiversity is in the soil, the less the PH influences the plant health.
I haven't done a lot to acidify the soil as ours is already far too acid. But your local garden center or if you are in the USA, agricultural extension,
should be able to offer some suggestions specific to your location.
In medieval texts, I've seen manure used to acidify the soil. The nettles on our farm grow best downhill from the neighbours horses and get a lot of fertilizer from them. When we lived with blueberries we used borax and alum, but the soil was deficient in those. Adding them if you have soil that is already rich in them wouldn't do well. But there are lots of other options. Ask locally and see what they use.
As I'm one to spend as little money as possible, and am lazy, I usually start with an area that is already almost there so it needs very little help from me as possible. Often hollows with soggy soil will be more nettle friendly.
