Agricultural grit - gravier agricole

Gardening

Is it possible to buy agricultural grit in France. Not seen it in local garden centres. We currently add Perlite for drainage but would prefer the grit. We’re looking for at least 20 kg size bags (currently we buy Perlite in 60l bags).

Thank you.

Try aquarium gravel. Not seen anything like grit in the Brico.

Gamm vert or a pet centre with ‘fish’ section will have this.

Alternatively a pool.supply might have grit/glass filter medium for pool filters..

Aquarium gravel is generally quite smooth. You want small sized gravier, which you can find in places that sell sand, gravel, stone etc for construction like Point P. Some big brico places will also sell smaller bags. Google gravier 1-5mm to find places near you.

Sharp sand from the Bricos etc is fine. Does the job at a fraction of the cost.

Look at Sable in Chausson Materiaux - the full range of options is there. Some is only available in "bulk. But basic washed alluvial 0-4 works to break up soil and increase drainage. After that there’s mixes up to fine gravel depending on what you need. The numbers refer to grain size - 0-4 is roughly UK sharp sand (fine sand up to small 4mm chunks) - the bigger the numbers the coarser it is

Depends on the soil and what you want to use the mix for. In wrong conditions it can form pans. Slightly lager grit often better for plants.

Bad idea, its used along airplane runways to discourage worms and hence flocks of birds which are dangerous to airplane engines on take off and landings, mainly its about the worms in your garden.

Try your local carrière as in my case for the drive, they had a display of all the types and colour of stones, sand, gravel etc and delivered onto my drive in big plastic one ton sacks. Fraction of the price of buying from bricos even including €70 delivery from them about 20kms away. You get to keep the sacks too which are very useful for cutting up and using as geotex type of use

Thanks everyone for your input. I’m going to check out the bricos to see if any of them has the size recommended by @JaneJones (1-5mm) and we’re not too far from a carrière so that’s a backup.
