What is everyone's opinion on watering your gardens with plain tap water compared to filtered water. We had a lot of rain at my house in the summer, which turned to borderline drought around the end of July. It seems like my garden and blueberries went to crap once they were only getting tap water. It's very possible that I just wasn't watering enough, but I also wonder if salt or minerals are building up in the soil when I water. Our water has a brown tint to it that I was told is manganese. I don't know if that would make a difference though. #activity source
