Hi Tracy, I found a supplier of Azomite in Camp Verde and as it turned out someone who works there was coming down to Phx for some car race he was in at Firebird racetrack. He carried it down to me and we met in a parking lot off I-17 near my home. I gave him a nice tomato start for his trouble.

Shipping must have killed you on that deal. You could side-dress with it, maybe a TBLS or so and scratch it in around the plants.

I'm also adding it to beds that are heavy clay, somewhere I read that it's good for breaking up and adding aeration to heavy soil.

I can see a slight difference between the two raised beds. The one with Azomite added *may* be taller/bushier plants but since one bed is Black Plum and the other is San Marzano, it's not a true experiement. Black Plums may just grow bigger and bushier than SM naturally. pH pings the same in both beds, about 7.
