## 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.
