    Answer This Question

    A:  There is a definite "vitamin" smell to Black Magic Bloom Boost. The odor is not harmful, nor does it indicate a problem with the product. The odor will dissipate after mixing with water.

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.

                    Works amazing
                    [This review was collected as part of a promotion.] I'm so happy I got this I usually use Epsom salt and others stuff to keep my vegetable plants from the leaves turning yellow and getting enough nitrogen into my plants. But with this its phosphorous so I no longer have to add to my plants. But also has potassium which is a huge plus I Buy bigger yield boosting soil so to have this also to boost the sets of blooms on my vegtable is a huge plus. But it also considerably helps with the amount of bulk of my tomatoes, potatoes zucchini and what not. I have also noticed my cherry tomatoes ripen better and stay fresh longer on my plants which is a buf issue I've always faced. I will keep purchasing as well as looking into more of the products.

                        This works well
                        [This review was collected as part of a promotion.] This is a nice product. I used it in my garden with success, but not sure if i saw a huge difference. It probably just needs a little bit more time. No mess. Like the bottle and cap. Easy storage.

                          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.

                              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.
