rooting hormone query
 

Hi group,

Sorry to bother you guys with another question (I looked on the net and
couldn't find an answer), but when one uses rooting hormone (ege 0.04%
IBA..etc), how is the stuff absorbed into the plant anyway? I presume
roots. But how about just normal plant tissue....can one apply it to
leaves and get the same result? What if one wanted to use it to get
roots out of a nodal keiki that hasn't rooted yet. Can it be applied
just to the base of the node? How long should one wait in order to
judge whether the hormone has done it's job? TIA

Cheers,
Xi
