FREQUENTLY ASKED QUESTIONS
Q What is crustacean meal fertilizer?
Crustacean meal is ground crab and shrimp shells containing 4% nitrogen, 12% calcium, 1.3% magnesium, and natural chitin. It's a slow-release organic fertilizer that strengthens plants while feeding beneficial soil microbes.
Q How does chitin help my plants?
Chitin feeds beneficial soil microbes that produce chitinase enzymes. These enzymes break down the chitin in pest insect eggs and fungal cell walls, providing natural pest and disease suppression without chemicals.
Q Will crustacean meal burn my plants?
No, it's a slow-release fertilizer with only 4% nitrogen, making burn very unlikely. The nutrients release gradually over 2–3 months. Just follow recommended rates and mix it into the soil.
Q Can I use it in containers?
Absolutely! Mix 1–2 tablespoons per gallon of potting mix when planting, then top-dress with 1–2 teaspoons per gallon every 4–6 weeks during the growing season.
Q Is it safe for organic gardening?
Yes! Our crustacean meal is made from food-grade shells with no synthetic additives. It meets organic standards and contains no heavy metals or harmful chemicals.
Q How long does it take to see results?
You'll typically see improved plant vigor within 2–3 weeks as the nitrogen becomes available. The calcium and chitin benefits develop over the entire growing season as soil biology improves.
