Volcanic Ash/rock dust
 

Finally after a year I’m settled and looking forward to planting a garden this year. Going to try and grow enough to preserve tomatoes through winter. I was reading a couple articles that said volcanic ash is good for the garden. Wondered if anyone here used it and how it may have affected the tomatoes. Help flavour or growth etc.

I remember reading that the volcanic ash soil is why the Hawaiian - Okinawan purple sweet potato tastes so good and is not grown commercially on the mainland, Most are imported from Hawaii.

Volcanoes are pretty scarce in Canada :)

Fortunately they sell it online LOL

Some good results it seems like.I use vermiculite really coarse grade since we get a lot of moisture,plus it breaks down and locks in nutrients and aeration is better for my containers

Volcanic ash would certainly be suitable for growing tomatoes from Mount Vesuvius, which should withstand storage for several months (Principe Borghese, Pienollo, etc.). I tried to store these varieties grown in normal soil, but I was not very successful. I mainly lacked potassium and other elements. I have also not found the chemical composition of such volcanic ash anywhere.

Unable to access the above search. I wonder if volcanic ash and rock dust is too dense for good growth to happen. Perhaps it is mixed in with soilless mix to help with fertilization. I have tried adding granite chips to seedling mix to ward off damping off problems, but then I have never had damping off so I was not sure it helped or hurt.

I use it and I believe that it is advantageous to do so,but there is many different qualities of it,you'll want one that has a high paramagnetic level.
