I have a lot of plants that are acid loving and are very sensitive, such as maples.
The tap water in my region comes from the Colorado river and thus has high alkalinity, i.e. high amounts of salts. Adding vinegar doesn't really help because although the water's pH is lowered, it salts still enter the soil and cause the soil substrate to increase in pH.
What are ways I can remedy this?
Some options I've considered:
- Adding granular sulfur to the soil. But does the sulfur counteract the salts such as calcium carbonate and remove them from the soil or does the sulfur just balance the pH? I'm worried about adding too many elements to the soil making it unstable
- Adding organic material, sphagnum moss, etc. Again, will this issue dissolve and get rid of the salts or will it just counteract the effects of the salts?
- Filling a bucket with water and letting it sit outside for a day. I know this rids the water of chlorine and lets the salts settle to the bottom, but not sure if this is that effective if I'm lugging around the bucket and salt just gets mixed in again.
What else can I try?
