Unfortunately, it is a bit late for me to mix anything in the soil at this time.

If a low pH is the only problem I need to fix, could watering with pH 8 water once a week balance the acidic rain for a nice pH of 6 or so? I have pH up solution

thnx peace
melodious fellow Reviewed by melodious fellow on . outdoor in containers, I think I heard I need calcium? It feels quite foolish to be asking this question. My first time growing in containers outdoors. I searched all over google and searched the forums. I know I need to supplement calcium because of acidic rain and such. My tap water has a pH in the high sevens, close to 8, perhaps this is due to calcium content? Would it be enough to water plants with tap water once a week or so? Using buckets ranging 2-5 gallons (planting late in season) I do not think I have access to calcium Rating: 5
