Rock dust was bought by Inverleith Allotments in Edinburgh at the end of 2014.   This followed the success a plot holder had with rock dust the previous year and he hoped others would try it and discover the benefits.  As we order our REMIN volcanic rock dust pallet for 2016, here are our results so far:

TAKING ON AN UNHEALTHY PLOT:   Late last summer I took on a neglected allotment with acidic, compacted soil infested with WIREWORM and covered in PERENNIAL WEEDS.  Existing SOFT FRUIT bushes did not look healthy and proved unproductive.   Being an organic gardener I was happy to include rock dust in the overall plan to improve the fertility of the soil.

I am now delighted at the quality and quantity of produce this season.  GOOSEBERRY and BLACKCURRANT bushes fruited well. Herbs, salad crops, potatoes, courgettes, beans and beetroot were prolific and delicious. Annuals planted for pollinators such as cornflowers, sweet peas and cosmos grew tall and repeatedly flowered for many months.     I’d really recommend rock dust to anyone!

A CONVERT:   Rock dust – I was sceptical but gave it a try and to my surprise I had a marked improvement in brassicas, potatoes, broad beans although rabbits went off with a high proportion of my crops!

I also applied some to my small cottage veg. garden in the Highlands and definitely increased quality of brassicas and onions   So, I’m a convert!


I was introduced to rock dust by an Edinburgh plot holder who’d used it for years.  He always had excellent vegetables – so it had to be worth a try.   I put the minimum annual application and planted as usual.   Everything grew, everything was healthy, which was quite a surprise as my plot seemed to have had every disease known to man.   I had struggled with club-root and white rot, soft fruit was not exciting and whilst stuff grew, it wasn’t remarkable.

Now in my second year with rock dust and I do notice the difference.  NO CLUB ROOT AT ALL, the LEEKS are happy and I’m even contemplating growing onions again.   My larder and freezer are full of jams and frozen BERRIES.  I’ve never grown such POTATOES – huge yields of good quality tubers – my biggest was just short of 2 pounds.    CARROTS used to grow OK but developed fangs, great for Veggie Monster section of our show but quite tricky to prepare to eat.   Since rock dust went down CARROTS develop long perfect roots.  Could be a coincidence – but I don’t think so.

I’m convinced rock dust has made a difference to the general health and vigour of my plot.  I recently visited Madagascar and drove through the major growing area where huge qualities of quality vegetables were grown.   I asked why particularly here and was told because the area is surrounded by volcanoes and the soil was therefore as good as it could be!

We need more volcanoes, soon, but until then I’ll stick with REMIN volcanic rock dust.            

BROCCOLI and BROADBEANS:  I bought some rock dust last year via Inverleith Allotments in Edinburgh and would like to report this season we grew the biggest broccoli I’ve ever seen and had a bumper crop of broad beans.   I’m sure there’s a connection with applying the rock dust.
