Last couple years have started using a guided nitrogen product. A 12-0-0.
All a slow release nitrogen made from feathers. My soil does not need the P or the K.
Like the results so far, and not paying for stuff my soil does not need.
See if I can find a picture of the label.
I think it cost $43.00 for a 50# bag. I got it from a greenhouse supply store , near you Teresa.
Looks a lot like alpha Pellets. But is made from feathers, an as you see a few other things . Slow release, last 3 months up to 6 mounths.
