A puzzle over rock garden soil
The standard mix for rock garden soil includes garden soil, sand, and peat. But I have read that most of the rock garden plants are lime-loving. Isn't this a contradiction, because peat is acidic and lime is alkaline? If a plant loves the alkaline lime, it should hate the acid peat, and vice versa.
I am puzzled how both peat and lime can be good for rock garden. Can someone help me with this puzzle?
