    What fertilizer are best for Hibiscus? I usually throw palm fertilizer around mine when I feed the palms. I have read good things about using liquid seaweed on Hibiscus also. I have seen over the past few weeks some beautiful fancy flowered ones in the local garden centers. I want to give them a try, but I know from my past experience I can not keep them looking good.

    I know the answer Scott, and it's not what you would think. But I'm going to wait for the expert to answer you so she can give the new software a spin.

    I'm not an expert but the most important thing is to have a low middle number. Hibiscus store phosphorus and if you feed them phosphorus it will build up to a toxic level. It will slowly kill them so NEVER use "super bloom" on them! I just use the same time release fertilizer Dean uses for his palms. Then I supplement them with K-Mag because our soil is potassium deficient. I occasionally sprinkle some Epsom salt and give them fish emulsion too.

    Potassium is key.

    yep - medium Nitrogen (N), LOW phosphorus - the middle number and high Potassium (K). I only know palm fertilizers they sell here in austria, and at least from their composition they have here they are the right thing for hibiscus.
    for the seaweed - I just started trying that out myself, should also be good for hibs. If I'm not completely mistaken Supernova sold by HVH contains seaweed (?).

    I checked all the fertilizers they sell here and discovered that the ones for veggies and berries are perfect for hibiscus regarding the numbers - they contain a lot of K because it also promotes the tastiness of tomatos etc.

    I once made that mistake that I wanted to set up a more regular fertilizing routine for my hibiscus using the one I already had at home - which was for blooming plants - and I managed to piss off even my big bushes seriously, that fertilizer almost killed them.

    Here are my ugly hibiscus bushes. The leaves never look healthy, but they do like to flower.
