Review: 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.
Review: good for what your - This stuff really works. I use it when transplanting and also for the first couple of weeks of watering when I'm planting from seed. A gallon lasts a long time, too.

### ⭐⭐⭐⭐⭐ good stuff for newly planted and transplanted plants
*by M***O on August 19, 2023*

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.
