Review: The delivery was speedy, and the product works as directed.
Review: i've been using neptune fish fertilizers for awhile, when my plants look a little limp and maybe overwatered, these help revive plants. I use them on my avocado trees, my blueberry plants and other vegetables and they all do well when i feed them a twice sometimes more a year watering with this concentrated fertilizer. Yes it smells, but it works. It's interesting that a broken down animal like fish can fertilize a plant, like it feeds on the protein, so not sure how it works, but just found it interesting and great that it works so well.

## Questions & Answers

**Q: Do you know in what way this is different from neptune's harvest sw136 organic seaweed plant food?**
A: Seaweed is more of a micronutrient supplier with little fertilizer content, while the Neptunes Harvest fish fertilizer is mostly fertilizer, with quite a lot of micronutrients too. But not as much as in seaweed.

**Q: Whats the difference between buying this and buying the neptune's harvest organic hydrolized fish & seaweed fertilizer ?**
A: The npk rating is different . Just the fish has a npk of 2-4-1 where as the fish with seaweed has npk of 2-3-1 . I would think the one with seaweed would contain more mircronutrients . But both are great and made with hydrolized fish .

**Q: Best way to apply product?  Anyway to attach to a hose?**
A: For small areas use a watering can.  For larger areas dilute with about 1/4-12 water and spray with a hose end sprayer.

**Q: Would this product be too "rich", or even inappropriate for young, recently planted Red Maple trees ?**
A: I think this product is great, but with a young tree, I would use a much weaker solution than they suggest.  I am very pleased with the results, but remember, you don't want your young tree to grow too fast.  Just use 1/r-1/3 of the solution and see how it grows.  I have used this on japanese maples and it really improves the color of the leaves.

I’ve used this fertilizer now for the last two years and bought it again this year, because I found it works very well with my vegetables. I would recommend to a friend…
