My first firtalizer job. What a nightmare. My custermer asked if i would firtalize his lawn. I said sure. I went to my local garden supply store and told the owner that i needed a good grade of firtalizer for my custermer , i also told him that this was my first job and that i needed his exspert openion on the subject. He told me that for this time of the year i would need 0-9-27 . Now comes the nightmare. I pulled around to the loading door and handed my ticket to the man who worked in the back loading this and that . I was not conserned what he was loading into my truck and drove off to my wating spreeder. Upon arriving to the job site i empited one bag of i thought was fitrerlizer into the hopper. i thought this ferterlizer looked a little strange and it spreed like it was heavy or something, but i figured my hardware man knew what he was doing. Lo and behold his loader loaded cattle mineral 22% salt . What am i looking at?
