    Good quality seaweed

    Good quality seaweed, highly concentrated , need to mix only 30 ml in 15 litre water solution , however container quality is poor and needs improvement, mine started leaking, from the bottom of container without opening the lid. Had to transfer the remaining quantity to another container .

    This seaweed product is really useful in organic gardening. I will buy again.

  20. 4.36 out of 5


    Got this after reading about seeweed fertilizers on google. I sprayed it on some of my citrus and other plants. My bougainvillea did have some leaf burns so did one of my citrus plant. But the plants did show some fresh growth after spraying. The bougainvillea leaves had turned paled green but now they have turned much darker.
    It you are going to use it as a foliar spray i would recommend testing it on a part of the plant before spraying the whole plant. You may need to adjust the concentrations so that there is no leaf burn.
    I like the fact that it has both the macro and micro nutrients.

  22. 4.36 out of 5


    Good product . I am using it as an inter-current fertilizer along with my other organic stuff. Yet to reach a definite conclusion about the effectiveness. I would say its a good addition to your shelf if you are into home grown vegetables.

    Simply say awesome….Can see the difference in my plants within 2 days……Plants get healthier and greenish…previously they look dull but now they are so alive…in my hibiscus,rose and gerbera plants they make the wonder…new shoots and flowers come out,flowers are rich in colour and leafs are very much green now,.. I’m beginner in gardening…so this product give me a lot of confidence in gardening…I make 1m.l / 1.125 liter water mixture and do foliage spray…so i’ll say this fertilizer is very strong….always use small amount and get ready to see the magic in your plants.

    Product works good. However ensure that you add dry manure or good organic compost to plants to see actual results. Organic tonic and compost will take a few months to break down so we need to have patience to see the results.

    The product is good for my flower plants , they are growing quite healthy.

    best seaweed extract fertilizer that i bought

    I had bought this product for the first time. after thinking all the pros and the cons. I was not very sure about this seaweed extract fertilizer, but since the seller seemed so sure and proud of the product and after so many good reviews, i decided to go ahead and buy it in any way. I have used on most of my plants my around 100 plants. The plants became healthy as if by magic and they started throwing flowers almost immediately. The blooms are overfilling the pots and overflowing. My garden now looks so beautiful. Thank you so much for this lovely product.

    Is liquid seaweed a good fertilizer ?

  36. 4.36 out of 5


    This is my second bottle,and it worked like magic for my plants. Most of my plants are babies and for the past 1 year, their growth had been very slow. Then, i came across this and used it. In few plants for ex. Portulaca(moss rose) you can see the result the 2nd day. Their growth boost up surprisingly.

Is seaweed Fertiliser high in nitrogen?Back to product

  1. Yes. Seaweed contains about 1.2 to 1.5 % nitrogen. Seaweed also contains potassium, which helps plants grow more vigorously.
