5-1-1 acid/alkaline question

jujustad(7B-8A)March 24, 2011

I am mixing up a load of 5-1-1 for my containers. I am putting a Japanese Maple in one (still very insecure about using gritty mix, had another failure and needed to get the JM out of the slop she was in before budding) and she needs an acid soil. I read somewhere on the forum that the 5-1-1 had a PH of 5.0 without the lime. Would you all advise that I add something to make the mix more acid for my JM and the flowers? Am I correct that I need to add lime to my veggie containers? I will be using FP fertilizer for all my containers. The frogs are starting to croak here!!!! It's one of my favorite things about Spring.

Thanks in advance for your help.

I've planted Japanese maples in mix very similar to the 5-1-1, and I've never had an issue.
Add the recommended dose of Garden Lime - 1 tablespoon per gallon of mix - and simply add white vinegar
to your watering solution periodically. It's far easier to adjust the pH of your water than it is to try and maintain
a specific soil pH (which is constantly changing, depending on temps, moisture levels, fertility levels, et cetera).

About how much vinegar and how often? Every time I water/ fertilize with weak FP? My water is a perfect 7. What does the lime do besides make the mix more alkaline? This is probably a loaded question huh :)?
thanks Josh,

In addition to slightly raising pH, the Lime is a source of Calcium, primarily.

Short answer, add a capful of white vinegar to a gallon of water as often as you think of it.

Long answer, take a gallon of water, add vinegar until your pH is between 5.0 - 5.8,
take note of that amount of vinegar, and then add the same amount to a gallon of water
whenever you water/fertigate.
