    Default high phosphorous = initiate root growth?

    i have bought a renanthera and aerides (all from the vanda i think) its been three months growth is minimal and roots havent grown any if there is its only my aerides which grows an inch then it stopped. leaves are pretty limp on my aerides. renantheras on the other hand hasnt developed any new roots. one of my renanthera's leaves started to turn yello. oh... anyway i read the whole fertilizer NPK thing and found out that higher potassium could initiate new roots (healthy + better rotos) is it true? ok so i bought a blossom booster which has higher phosphorous and was wondering if this statement is true. im planning on using it. to help my chids grow roots. thanks guys!

    Talking higher phosphorous yield new roots?

    can a higher phosphorous help initiate root growths ive tried hormex but it didnt work. its been three months now i have 2 renanthera and one aerides their growth seems to be stunted. if ever its very minimal. i only see one roots in aerides and just made an inch. its pretty slow.. with my renanthera hasnt produce any roots yet. i read an article dat phosphorous can help initiate roots on orchids... is this true? if it does? is it a good thing that ill change my fertilizer to a higher phosphorous since i never use it before... thanks...

    Tried some willow tea yet?
    Just add some boiling water to a cup full of willow twigs (not dead ones from the ground), look for nice yellow tipped ones.
    Let it sit for a day then seperate water from twigs...
    Its the same stuff you get in root hormone bottles... except its not synthetic....

    I have heard of using "willow water" as a rooting agent ... Thanks for the recipe even though I doubt I can find willow twigs in New York City ....

    Lambert, If it is the Salasillic acid in the willow bark that triggers growth...that is aspirin.

    Cin, you are right, I looked for info online and it is the Salicylic acid that would be the responsible agent for promoting root growth.

    Baby aspirin time. I don't know if these orchids have a head ache, but this should cure it quick!

    Laurent, does that mean that you can dissolve Aspirin in water and use that or do you have to use pure salicylic acid?
