Bad news. The rain here has a pH of 4 or below... can't tell, as 4 is as low as my liquid test kit goes. I still have not found any lime and I really do not want to order online.

Lots of drought followed by violent t-storms, repeat cycle is the weather here.
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
