I am about to give my front garden a "make-over" and I intend to have a
low maintenance area with a white gravel and a few interesting plants.

I have seen white dolomite available, and it would give the effect I am
looking for, but would it affect the pH of the ground and cause a
problem getting suitable plants?

Are there any other white aggregates I could use that are more inert?

Thanks,

Nick.

Dolomite is a rather inert form of limestone, and would require quite a
bit of acidic rain to leech. Marble is even more inert.Granite &
Quartzite (white metamorphic sandstone) are as inert as they go.

That being said, I have a marble chip pathway through a native woodland
plant garden & I am always picking voluteers from among the pebbles.
