I haven't fertilized in years. However, the last couple of times, I went to a farm fertilizer dealer and bought liquid fertilizer and sprayed it on. It was much less expensive and not as labor intensive. I don't recall the mix %, probably triple 13, but it worked as well as the bagged specialized stuff. Right now, pelletized farm stuff is $400 per ton.
I wanted to ask about that. Bagged, granular fertilizer in triple 13 is readily available here at farm supply places, etc. It is cheaper than the specialized stuff, which I would have to order. Is there any reason it would not work?
