This is a slow-release granular organic fertilizer from Dr. Mani built on crab meal, cold-processed kelp and volcanic ash minerals, with an NPK of 7-4-4 plus amino acids. The crab meal brings chitin to feed soil microbes and support plant defenses, while the kelp supplies natural growth hormones for roots and flowering. It suits gardeners who want to rebuild soil biology instead of feeding with synthetic salts, and it is meant to be paired with the brand's liquid Plant Super Boost as a regimen. Against typical all-purpose synthetics it is gentler and slower, so results build over a season rather than showing in days.

Crab, Kelp & Amino Acids is a slow-release granular organic fertilizer with a 7-4-4 NPK analysis, plus 6% calcium and 2% magnesium and the essential micronutrients. It is made with crab meal, cold-processed kelp, minerals from volcanic ash, and blood, bone and feather meals with langbeinite. Each application feeds plants for 4 weeks.
The formula has a very low salt index and contains no synthetic urea, salt-based fertilizers, PFAS, sludge, biosolids, artificial fillers or dyes. It is kid-, pet- and pollinator-safe. Crab meal supplies chitin, kelp supplies natural plant hormones, and volcanic ash supplies trace elements and silica.
To use it, sprinkle it around the root zone and water it in. It suits citrus, tropical trees, vegetable gardens, raised beds, flower beds, shrubs, turf-grass, lawns and houseplants. Monthly application is recommended for citrus and tropical trees such as mango, guava, banana and avocado. It can be used together with Dr. Mani's Magic - Plant Super Boost.
