Pulverised Basalt?

[frazwell]

Anyone know where to purchase Pulverised Basalt.
I was told it works great for tomatoes.

Don't know who told you that. It's rock dust. It might add some trace minerals. But I googled it, not having heard of it, and didn't find very much and what there was looked pretty fringe-y and not trust worthy. Good organic fertilizers, that have things like kelp would feed your plants better and have minerals...

check your local rock quarry's if you have any. most of the time they will give you the real fine stuff for free or VERY cheap. i got one ton( yes a ton..) of rock dust for 5$..... more than i will ever need even for my large garden. i just had to make a few trips in my truck haha.

rock powders are good for minerals and stimulate soil microbial life.
