## Questions & Answers

**Q: Does this product arrive with any protective seal? I received one today without anything and want to ensure it hasn’t been tampered with etc.**
A: This product arrives sealed in its own container and is a fantastic product.

**Q: How do you apply this on roses? Do I apply this to the soil or spray the whole plant? Thank you**
A: This version of Maxsea is intended to be dissolved in water and use in solution hence hydroponic.  I use it on carnivorous plants that will absorb the fertilizer through their foliage.  For roses I would use one of the other Maxsea fertilizers. Something like the Bloom Plant version.  I would apply it to the soil.

**Q: Why doesn't Amazon ship to Canada? I ordered it before and now they don't?**
A: It would depend on the vendor.  Try another vendor it may work.

**Q: What are the ingredients and in what concentration?**
A: This is just a soluble 16-16-16 fertilizer with some dried seaweed extract in it. 16% each of nitrogen, phosphorus and potassium with the added Seaweed for some added micro nutrients.
