I would fertilize I. tridentata VERY little, if at all. If you must,
Miracid is probably your best bet,since it is native to NC/Georgia,
where the soil is acidic. I have a white tridentata and a violet one (I
think--it has never bloomed) growing side by side in well-drained sandy
loam. The white is a creamy color and quite vigorous, with over 30
bloomstalks. The only special treatment that it receives is irrigation
in the summer. Good luck.
