I would highly this formula of "Black Magic" to anyone who wants their plants to bloom beautiful flowers!! As you can see, they bloomed very well!!!!

    Black Magic bloom boost
    [This review was collected as part of a promotion.] I have been using this BLACK MAGIC Bloom boost for a short time. I am so happy with the results I’m seeing I have a flowering tomato plants with teeny tiny tomatoes already , the plant looks to be a much deeper green in color and very healthy I followed the directions to the t and I am impressed there is no smell. It looks like with this product I can grow tomatoes inside all year, thank you Black Magis.

      Great product
      [This review was collected as part of a promotion.] My mom is so happy with this product. Last year we had a cold front that ruin all her flowers & after that she struggle with them. They just would bloom the same way like they used to; however she has being using the magic bloom for over a month & she already saw a big difference. We are very satisfied with the product. I love to see my mom happy her garden is everything for her.

        [This review was collected as part of a promotion.] Black Magic Bloom Boost has all the right ingredients to provide a lot of blooms for my flowers. It is very easy to mix up and apply. I am now waiting to see the results as I just recently planted my spring flowers.

          Unable to give a fair review
          [This review was collected as part of a promotion.] I have not had this product long enough to give it a fair review. It takes longer than a week after applying this product to a bloom to see what effect it is going to have on the bloom. Therefore I cannot give this product a fair review.
