I just bought one of those 3 in 1 soil/light testers. I tested my mini bogs and pots - - my sarr mini bogs are not acidic at all!!! I know I never tested the sand, I am guessing that it has raised the acidity beyond neutral. The plants are just coming out of dormancy and are shooting up flowers. They have been planted in this sphagnum/sand mix for about 18 months now and did well last summer.
Any thoughts on what I should do?
Should I replant?
Can I make the soil acidic again? Will it only be temporary?
Other than testing each batch/brand of sand, how can I be sure I am getting neutral sand?
