If you are going to use the marble around (not covering) plants already growing, they would be nice. Just remember these chips can be up to 1" and are heavier than garden "pebbles". Also, rinse the chips first to get rid of the marble dust.
They are good at keeping weeds out, but I don't know that it would help keep out bugs. There are probably fewer bugs with this than open soil, and I haven't seen any bug problems since I installed the marble chips.
size is number one gravel on scale. approximately 3/4 in less than a golf ball
I bought mine a few months ago. Intended for outside so it didn’t matter if rocks were wet. I would avoid breathing dust of any sort. Not toxic to handle.
As far as I know, they only come in white. For me the advantage was cost. 84 bags cost me approx 350$. Stones would have been almost 1000$. Color wise, stones are not as likely to be as bright white. It all depends on what color scheme you are going for. I thought about doing black but after buying a couple bags of black stones and laying them out, it just didn’t look as good as I thought.
have only seen in white. the white has grey tones with the white color. if looking for black you might try rubber much which has multi different colors.
The rocks don’t stay white like they should, when the sand that’s inside looks brown I know the rocks will loose their color on the first day it rains. I wouldn’t recommend them to any my other customers.
How deep do you plan to spread them? Need that info first!
once marble has been saturated with water it takes a while to dry out. white color will return after it drys out
usually mid april and may
