Ask Ruth: Types of Lime How to Use Them | Organic ...
Jun 01, 2009· Hi Terry, what you want is dolomitic lime, not hydrated lime (which will burn the plants). According to this SF Gate article, "Hydrated lime is more concentrated than limestone [, dolomitic lime] and it neutralizes soil acidity more quickly, but it is also difficult to work with because it is somewhat caustic."Dolomite lime can be found at all garden centers and is perfectly safe.
