Review: Big Yields, Beautiful Plants, Fair Price - My tomatoes and herbs love it. So do my houseplants. I love it for two reasons: One, it helps me get big vegetable yields and grow beautiful plants. Two, it's all natural. As for the price, it's fair. Not the cheapest fertilizer on the market, but it's worth every penny.
Review: Love this stuff - I think this is a great organic fertilizer that can be used throughout your garden whether your plants are in the ground, potted, or indoors for seedlings or established plants. I highly recommend it. All of my plants love it and it is not harsh on any of them. Definitely follow the instructions on the bottle. The key for me is to not water the plants right before. If it is for potted plants and depending on the size I do little by little. Then after I finish I will go back to the first one to see if it needs more. You don't want the fertilizer draining out of the bottle - you want to make sure it all stays in the soil. This is fermented fish and seaweed so the concentrate in the bottle does have a punch as expected but once it is diluted there is barely any smell or any off putting smell. That is also why I do little by little so the fertilizer does not drain down into the drip trays. I can see it making the smell stronger as it evaporates.

## Features

- Grow a beautiful vegetable garden
- Flowers and foliage will be stronger and more colorful
- Blooms will be more plentiful, fragrant and longer lasting
- Easy to mix and apply by hand, sprayer, or drip line

### ⭐⭐⭐⭐⭐ Smells TERRIBLE, but highly effective!
*by J***A on January 9, 2026*

I got this to pretreat garlic before planting. Smelled so gross (like fish LOL duh). However, every single garlic bulb planted has sprouted. It surely did not disappoint me!
