Rooting hormone/powder?

[Craig.a.c]

Does anyone sprinkle a little of this through their potting mixture while repotting their trees?

Honestly, i can see no need to do this

I haven't done it myself. I just thought it may help with the growth of fresh roots faster thats all.

Hi Craig, I'm not sure there would be any point. As far as I know, the powder / gel needs to come into direct contact with the vascular tissue (Cambium) - the area responsible for generating new growth cells. Having said that, the more I think about it, given that the powder converts into a soluble form, it may actually be doable. Very interesting question mate. I think Joel could better answer this. Where are you Joel my gangly spindly old friend??

Hi Craig
Rooting hormone is Auxin, the same stuff found in Super thrive, Seasol and Plant starter. It is in high doses when used as a rooting hormone in cuttings it is applied to stem tissue. If used at the same dose on roots it can/will kill them and/or the tree.
People have and do sprinkle rooting hormone powder in the soil when repotting. I would not recommend it as the dose of Auxin that should be used is very specific so I would stick with what the chemists have made to do the job in Seasol Super thrive or plant starter.
