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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent fertilizer *by L***A on 31 May 2023* 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.
