Rest assured that you'll not be killing your plants with chemical burns like when you use synthetic fertilisers without circumspection. And the plants love it (including cacti). It is advertised to leech out N:P:K in proportion to 2:3:1 ratio and the seaweed Kelp (Ascophyllum Nodosum) extract will provide your plants with growth hormones like auxins, gibberellins, and cytokinins. If you use the fertiliser in quantities advised by the manufacturer you'll not perceive the smell even at a foot distance and the smell is kind of 'sea-like' or of fresh fish and not even off-putting for most. ## Frequently Bought Together - Neptune's Harvest Fish & Seaweed Fertilizer 2-3-1 (36 Ounce) - Neptune's Harvest Tomato & Veg Fertilizer 2-4-2, 36 oz - Neptune's Harvest Fish Fertilizer 2-4-1, 36 Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/254328018-fish-and-seaweed-fertilizer-2-3-1-36-ounce](https://www.desertcart.us/products/254328018-fish-and-seaweed-fertilizer-2-3-1-36-ounce) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-24*
