Lime will in fact reduce your alkaline levels. Not sure how much to use but I would suggest getting a PH meter and starting with small amounts. Good luck.
adding lime to change soil ph
ok i have been watering my plants with properly phed water. but my soil ph stays high. im using happy frog. and have everything in cloth pots and could prolly put a few mor inches of soil in the pot now that the plants r bigger. can i mix lime into some soil and add it to the top of the soil to lower the ph. and if so how much should i add? its at 7.5 -8 and its causing a few issues

Topdress with dolomite lime 1tbsp/g . Lime buffers your PH to around 7 .
Make sure it's the fine 'fast acting' lime or crush it a bit if it's coarse.
what sort of ph meter are you using and is it calibrated properly. if your using a soil testing kit which changes colour then dont believe what it says, my one kept lieing to me!
good luck x (fucked if im writing your full name)

Lime is for raising pH so don't use any. ok?
There is no maximum really what you will get if you get to a level that buffers the soil is 6.86 which is the ph of carbonate which is what your blood is also. Bicarb of Soda or Baking soda is smaller grained and more available. if you use that just mix in water and immediately after swishing it around deliver it to the plants and then add soil if you want.
Muffy the assertion you make is an excellent reason to relate this dicta of general chemistry ie " a weak acid is a base to a strong acid." ie it's all in where you are looking at unless you remember the ph of the substance you are adding.
I'm pretty sure lime is way over neutral. I should say that if your pH is already too high then adding lime won't help. It will in fact make it more difficult to get to where you want to be and stay.
Umm lime is acidic it lowers the ph of akaline soil etc. That's one of the reasons we use dolomite lime in our soil .Originally Posted by Muffy
Sulpher is akaline it raises your soil ph . Where do you get your info from ? All he needs to do is top dress with dolomite lime and water with ph'ed water .
when u say top dress do u just mean sprinkle it on top or sould i mixitwith somesoil first and add it to the pots?
