Rock Dust

[Tracey]

Have any Grapes used 'Rock Dust' in their gardens?

Never heard of it, just google and found this site,
Rock Dust Grows Extra-Big Vegetables (and Might Save Us from Global Warming)
"says rock dust grows extra big veg & might save us from globalwarming" gonna read up on that later

I work in a granite quarry, our rock dust is like talcum powder.

It has got to be worth a go chucking some onto my beds and forking in, even if it just acts as a soil conditioner.

My Dad swears by this stuff. We have been doing an experiment putting it on one side of the bed and not the other, it does seem to make a bit of difference but not sure this wasn't fluke!!! It is expensive to buy commercially, we go to a local stone masons and take it for free now.
have a go piglet it certainly hasn't had a detremental effect on our plot and if you can get it for free........... I'd wait for a wet day to put it on though, it blows away rather quickly otherwise.

I'm just about to this afternoon! The site I'm on has been inactive for quite a few years and is on a steep hill so I figured the soil could do with as much help as it could get. I'll let you know how it goes!

OK well I would have done if I hadn't discovered the ground was frozen solid

SEER® Rockdust®: Top dressing of 420 million years old, freshly ground, untreated volcanic rock from Scottish quarries. Rigorous trials and scientific analysis show this to be safe to add to soils and compost.

There are two basic types of igneous rocks. There are the rocks that make it to the surface (extrusive) and the ones that are stuck in the crust just below the surface (intrusive). These igneous types have all hardened after being molten rock. If you walk around a volcano, you will find those extrusive types. The intrusive types are usually found in areas called plutons and dikes, big old pools of molten rock that were just beneath the surface. Some examples of igneous rock are granite, all volcanic rock, basalt, and obsidian.

Hmmm, sounds like you could get yourself a nice little side-line with your granite dust PW! If I lived a bit nearer I'd pop round for a bag?!

How about a 20 tonne load?

How about a 20 tonne load?

Showing off again!

Let us know if you try some how it goes.

Ha ha, we quarry about 4.5 million tonnes a year SBP and secondary crush about 18000 tonne a day.

We produce a product called dust which is like sand, marshalls the slab manufacturers take about 500 tonne aday. However in the screenhouse thereis real rock dust, like talcum powder and that is what I shall be trying.
