## Questions & Answers

**Q: what is chitin?**
A: Chitin is most commonly recognizable as the hard whitish parts of a crab shell although it is one of the the main substances in many exoskeletons (creatures that are hard on the outside-- like crabs, lobsters and many insects-- have exoskeletons rather than internal bones).

**Q: When putting a plant in the ground, should this be put around the roots or near the top of the soil? All tips appreciated!**
A: Hi there, we generously applied the shells to the top of the soil of our raised beds and then tilled in to a depth of about 6-8". We found that this product really helped us with the calcium deficiency we were having here in Colorado, causing end-rot on our tomatoes and peppers. I think we will try applying it around the base of our plants as needed  (after big rain events) next year too because, even though it helped tremendously, a few of our plants still had some problems. I think either application of the shells, around roots or top, will work, depending on the severity and nature of your problem or your fertilizing needs. Hope this helps a little.

**Q: I assume the crab has been cooked in some way before the shell is removed.  Does anyone know how the shell is processed?**
A: I doubt it's been processed. It's simply crushed crab and crab shell. Smells like it too. Ingredients: Crushed crab and crab shell.

**Q: Can this product be used as fertilizer for my spring bulbs ?**
A: Yes, it is a fertilizer. A light fertilizer. IngredientsNitrogen Total N (2.63%), Phosphate Total P205 (3.23%), Potash K20 (0.28%), Sulfur (0.2%), Magnesium (1.33%), Calcium (22.95%), Sodium (0.53%), Iron (3239 ppm), Manganese (56 ppm), Copper (23 ppm), Zinc (45 ppm), moisture (10.29%), pH (6)

### ⭐⭐⭐⭐⭐ Great product,works well
*by B***T on November 14, 2025*

### ⭐⭐⭐⭐⭐ Looks good on the soil.
*by D***S on November 25, 2025*

Plants liked it! And it's pretty on the soil. Hopefully nematodes don't like it.

### ⭐⭐⭐⭐⭐ Smelly, but that's a good thing.
*by R***S on August 9, 2025*

This stuff stinks, but that's to be expected since it's crushed lobster anf crab. But it's easy to cover with a little soil, and you want this to be natural and not processed. I use it with my plants and it seems to help. I understand it keeps harmful nematodes away from plants. It's easy to spread, I mix it into my soil mix.
