SECOND purchase of Bloom City’s Root Fertilizer
The first time I bought this product, I had also bought another product by Bloom City (The Seaweed/Kelp Fertilizer) as well as a few other fertilizers. I saw great results in my vegetable garden, but realized that this didn’t prove the Root Fertilizer’s efficacy due to using multiple products at the same time. So as a second run I bought 3 products by Bloom City but only used the Root Fertilizer on my houseplants. I didn’t notice any difference in plant health/quality or root growth during the first week. But almost overnight, a week after using this product, I noticed not only fresh hyphae root growth, but also plant growth and deep green leaves for plants that seemed to have stayed the same size and looked unhealthy for a year or more. Anyway, this was extremely user friendly, lacks any odor making it perfect for indoor as well as outdoor plants, albeit, a bit expensive for the quantity provided. But overall, if you can afford it, it’s well worth the extra cost.

Awesome!
This stuff works great! This is especially good for established plants and using a bottom watering method. Noticeable improvement in the plants in a matter of days. Make sure to mix the nutrient solution as instructed and I believe you will be happy with the results.

Little bottle BIG EFFECT
This product is a good value for the money, even though the bottle is kind of small it doesn’t take very much at all for it to give you beautiful plants at a fast grow rate. The instructions are very clear so it’s easy to use. It does smell like fish, but that’s what makes it a quality fertilizer It’s made with fish emulsion, which are highly beneficial to plants. And increases the grow rate exponentially it makes your greens greener and your flowers bigger and more robust

good stuff for newly planted and transplanted plants
I just bought a few new plants for this year, tomato, jalapeno, and 3 blueberry plants. They all were small in those very small round pots but i transplanted into pots that were at least 5 gallon or bigger. I used this to stimulate root growth and overall growth of my fruit/vegetable plants. My jalapeno grew from like 8" tall to over 3ft tall with like 20 jalapenos already in 3 months. My tomato plant is growing small cherry tomatoes already as well. My blueberry plants grew at least double in size from frail small green plants about 6" long to multiple branches at least double that now over 12" long branches and looking healthy. You only need very little and i only have giving it for about 3 times now, so it works well. I use a large pitcher and mix like 2 table spoons and fill the pitcher and then pour on all my fruit/vegetable plants/trees and that's it, super easy to use. 5 stars.
