Limestone is fine in small amounts. It slowly releases Calcium in the presence of acid and can have an unpredictable impact on the soil pH so use it sparingly.

To get an idea of its activity, put a little into a cup and add some vinegar - you should see it fizzle as the limestone dissolves.

Helen,

A little lime is helpful in a soil mix, but as X indicates, it should by no means be anything other than a minor component in a soil mix.

Xerophyte thank you so much! I will not use it.
