I've used Azomite on my peonies for a couple of years, last year in combination with BulbTone. I didn't think I saw any difference directly attributable to the Azomite so I didn't use it this spring, just BulbTone. I'm noticing now that I'm seeing quite a few more floppy stems, guess I found its benefit! Won't make that mistake again, will order some soon for fall application.
