  19. Manu

  20. Dipak

    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.

  21. Rita

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.

  26. Divya

    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.

In few plants for ex. Portulaca(moss rose) you can see the result the 2nd day. Their growth boost up surprisingly.
