Fertilome Blooming and Rooting Reviews

Fertilome Fertilizer

Fertilome Blooming and Rooting (9-58-8)

Fertilome soluble plant food is a relatively obscure fertilizer on Amazon that is manufactured in China. I call Fertilome is as obscure because 800+ fertilizer brands have more sales. However, taking into account a large number of positive reviews is popular.
Fertilome can be used in all stages of plant growth, as it helps with the soil and roots and promotes larger and more robust flowering. This product is highly rated. But, they say it works for the following tomatoes, pansies, orchids, roses, and plants that have fruit. Cannabis is not listed, which is understandable. So, the question that needs to ask is, does it work well for cannabis? I will answer this question by first examining this fertilizer and then find out whether or not Fertilome should be added to your cannabis fertilizer arsenal.

What Is Fertilome Blooming and Rooting Made Of?

For fertilizer, the first number is always the nitrogen, the second number is always phosphorus, and the third number is always potash

The  9-58-8 fertilizer means that Fertilome composed of the following nutrients:

  • 9% Nitrogen-Helps with leaf growth for cannabis
  • 58%-Phosphorus (“Bud Growth”)-Helps with photosynthesis, energy transfer, starches, sugars, and works passing on one plant’s genetics to the next plant.
  • 8%-Potassium (“Potash”)-Potash works to help the plant feed as it helps break down sugars that can be used as plant food. Also, helps with the plant processing water.

Pros and Cons of Fertilome Blooming and Rooting


  • Reviews-Very high overall score accompanied by numerous reviews.
  • Simple-Very user friendly, and the dissolved granules are easy to apply
  • Quick results
  • Works Well- Its ability to help with flowering and hanging flower baskets were especially praised.


  • Expensive– A reviewer stated that considering what you get, this product is costly.
  • Packaging– Some reviewers were mad that the listing showed a plastic container and not a bag. This was an issue that fertilizer bags cannot be re-sealed; so, it will need to be placed in a separate box for storage.
  • Cannabis-I was unable to find any reputable sources mentioning if this is good for cannabis.

Does It Work For Cannabis?

Unfortunately, I could not find any definitive answer (yes or no) on whether or not Fertilime should be used for cannabis. Also, the only information that I could find for this fertilizer is on cannabis forum threads. Forum threads can be helpful. But, again, there is no real way to verify the expertise of an anonymous grower’s advice on a forum. For the pro Fertilome forum thread, a reviewer (who used Fertilome) stated that he went to cloning to bloom in four to five weeks. However, another thread said that the phosphorus levels for Fertilome are the way to high. Too high phosphorus levels for cannabis can result in turning your leafs yellow or “nute burn.”

WARNING-Cannabis growers need to avoid any fertilizer that says they are either extended-release or slow acting.


As stated, I could not find any definitive answers or a consensus on whether or not Fertilome is a good fertilizer for your cannabis crops. They are not a large company, and this fertilizer can be tough to find. So, it is not surprising that little info on Fertilome and cannabis cannot be found. Don’t get me wrong, this product is highly rated, and its results are extensively praised. It is a quality fertilizer. However, none of those praises mentioned marijuana. So, if you are going to try Fertilome, I would test it out on a plant that you would not be heartbroken if it were to be damaged, and see how it goes. Based on the results on that one plant, you should either not use it or use it on your other plants.
