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 products such as calmag. What other ways could I fix the problem of growing in containers outdoors?
Could I crush up some of those calcium tablets derived from oyster shells marketed for osteoporosis and add to water, or is there anything else I could add to the water. Anything organic or anything that can be found at Lowes?

If I did have to resort to driving an hour to a shop to buy a product, are they rather cheap, and how and how often to apply?

Thanks in advance, I'll love you!

peace

p.s. worst case scenario, anyone ever grown outdoors successfully in containers without calcium supps?
