I use 4-10-10 or bone meal at planting, and have been working in bone meal around every plant in the spring. As I said, that has gotten extremely labor intensive. I fertilize the LA's and JI's more and with 8-8-8 or 10-10-10.
Tom - when you say "side dress" does that mean you are working it in around each iris? Rob - scratched around each iris?
Janie - yes, I meant like using a broadcast spreader that does indeed throw it everywhere instead of hand dropping fertilizer around each rhizome.
Gabe - is your concoction liquid or pellet?
I never thought about squirrels liking bone meal. I have never had much problem with it, but think my bearded iris need something more this year.
