I just put down some centipede sod in BR. Would it help to use some root stimulator (Indole-3-butyric acid aka IBA) to help the roots establish before freezing temps get here? This mix also contains 4-10-3 fertilizer.

Can I also use this mix now on newly planted trees and shrubs?

Ugh... indole 3 butyric acid is an auxin. Kelp has auxins, cytokinins, gibberellins, minerals, and some trace elements. Items sold as iba have more iba than kelp, but lack all the other things.
