Good day

Please assist. I would like to know if the rock dust from drilling a borehole can be used in the garden or on the grass. Will it damage my grass?

Thank you

Do you know what type of rock is in the dust?

Unfortunately not, and the drilling company have already left the site.

It might be better to use it for paths or your driveway in that case.

You might consider adding the rock dust to a compost pile and letting it age in the compost before adding it to your garden; it helps to add minerals to the soil but it does not happen quickly.

Some folks actually package and sell rock dust.

Do rocks improve with age?

A geologist would think so.

The rocks do not necessarily improve with age. But...the availability of the minerals takes time. That's why I suggest the compost bin as the best place to glean some minerals from the rock dust.

Think of it this way. A tree, a huge tree, sends roots deep into the soil. The roots get nutrients from deep in the soil. Those nutrients are in the leaves and in the autumn when deciduous trees shed leaves, the nutrients are in those leaves. If we rake up the leaves in a timely manner and place the leaves (shredded or whole) into the compost bin, the nutrients then become part of the compost. It is similar to the rock dust. But it will take more time for the nutrients to find their way out of the rock dust and into the compost.

Depending on the soil you have it cannot really hurt.
How fine is the dust?
If it is real fine and you have clay type soil spread it around; if you have sandy soil it will make no difference.
Get it wet and see how it reacts. If it gets slimy, spread it thin.
I used to often put the very fine dust from cutting cement blocks and pavers in the garden .
