    Hi Susie, try Muirs.co in Landsdale Perth.

    I have had success with their branch in Manjimup.

    Hi Susie,

    Most seaweed powders on the market are extracted with potassium hydroxide. This changes the nature of its properties somewhat unlike seaweed products that are produced mechanically or through fermentation.

    The products I prefer to use for seed coating are Seaperia powder or the the fermented seaweed liquid from Marine Supplies in Fremantle.

    These cost a bit more but you only need a bit for seed coating.
