    I'm interested to hear other peoples opinions on packet/bottled rooting hormone...

    Myself, I dont use it and generally have a 90-95pc strike rate on most cuttings.

    Has there been any evidence to suggest it has a detrimental effect on the soil or health?

    Thanks :)

    Oh dear Steve - that is beneath even you.
    I have used honey and willow bark tea to good effect but you are right that nothing can often give very good results. I do not know much about the powder though.

    Rooting Hormone....Viagra ... LOL

    dont they use viagra in old folks homes to stop the guys from falling out of bed?
    kinda like a kickstand on a motorbike.... ;-)

    I prefer to buy IBA (Indole Butyric Acid) in 8000ppm (0.8% soln)concentration and dilute as required depending on cutings.
    I dont bother useing it on some cuttings, but strike rate of others is definitely improved -ie. higher percentage, more roots and quicker development.

    some species require high concentration
    eg. Pecan hardwood cuttings - 50cm long, 2-3cm dia. taken in Autumn treated with 8000-10,000 ppm. IBA

    generally the harder wood and more difficult to take require higher conc.
    softwood generally 500ppm (0.05%)-1000ppm. (0.1%)

    the liquid gives flexibility of dilution, and application -ie. dipping just cut ends or whole cuttings into 'bath' of more dilute IBA for soak and to prevent drying.
    with powders (talc is the carrier/filler), and to a lesser extent, Gels, you dont have this flexibility.

    with some species though powder tends to be better.

    Re soils.
    Such small concentrations are uses as to have negligable effect on good bio- active soil.

    re.health - plants- IBA appears to be non-toxic over a wide range of concentrations
    - human health- it is a hormone and thus has effect on living things (not just plants) ,
    so it best to use gloves and excercise appropriate precautions.


    Another hormone I use is GA-3 (Gibberillic acid).
    I find it very valuable for raising 'difficult to germinate' seeds.
    GA-3 can overcome some forms of seed dormancy and increase germ rate and hasten germination
