Limestone screening?

DavidL.caJuly 14, 2014

Drove past a farm and rock shop and went in to try my luck with some soil amendment ingredient. They didn't have pumice and turface (of course), but they do have some pea gravel (which I think is too big) and these limestone screening which kind of look like they could be the grit part of the grittier mix.

Other things.. only pea gravel and the limestone screening looks possible to use in soil though

Is there any disadvantage to use these?

People typically use granite for this part of the mix because it's inert. Limestone, on the other hand, is quite alkaline. Some people add some limestone to mixes for plants that prefer a more alkaline soil, but it's probably not a good idea for a general purpose mix, especially if it's going to be a significant percentage of your mix.
