Hydrated lime starts working almost immediately.....It has a tendency to burn though

Dolomite takes a little longer and usually won't cause any burn as long as it is mixed into the soil thoroughly.

I add about 2 TBS of Dolomite lime to every 5 gallons of soil mix,I water with well water that's a PH of 7.2
my run off is usually 6.2-6.5 PH
