Okay I understood the NPK thing, its the name which had me confused here. I don't think I have ever seen it in our stores.
I do need to find a good fertilizer low in nitrogen. My Campsis radicans (Trumpet Vine) doesn't need the nitogen and it will take any available nitrogen and grows like a weed. It just hasn't bloomed too very well the past couple of summers. I guess that is one area I need to look into for a properly blooming vine. Only thing is.......................it is growing all over the place now. When it isn't happy with its site it doesn't do much but put it where it is happy and it takes over. I've been pulling it out of my peonies, my weigela, hollyhocks and everything else. I don't want to kill it I just want it to behave and stay on its own side of the yard...
