In fact I went to another brand to “save money” and I’m not impressed with it. Will be switching back to Neptunes Harvest once the other is done. It makes my plants thrive!! Great consistency and thickness. It does smell gross but what do you expect lol. ### ⭐⭐⭐⭐⭐ My Magical Neptune Elixir *by on Reviewed in the United States March 2, 2024* I use this on my garden one week out of the month, with regular fertilizer two weeks of the month, and also regular bone meal. I did notice that when I use this kelp stuff, it seems to generate new roots from the base of the plant, get stronger, and producing more fruits and veggies! These things are most likely to happen during/after kelp week.This stuff goes a long way for a small bottle. It dissolves perfectly, and there is a very faint ocean smell to the water when it is mixed in. Nothing terrible smelling.We’ve been using this product for years in our garden, and it truly gives an extra boost to any plants. Our garden truly thrives, and produces so many fruits and vegetables. We use it on almost everything: our flowers, strawberries, blueberries, melons, tomatoes, lettuce, garlic, cucumbers, onions, peppers, carrots, squash plants and more!Fish and Seaweed are known to build the natural sugar in plants. Flowers and foliage will be stronger and more colorful. Adding this to your garden will give you better vegetables/fruit yields. This is a great fertilizer for a few key reasons: The first is that it's a great source of Phosphorus which is used by new plants to produce strong roots and so is great for any root vegetables! This is a secret ingredient that all gardeners use to improve their garden! I highly recommend using for your plants! ### ⭐⭐⭐⭐⭐ Great fertilizer - fishy smell *by on Reviewed in the United States May 19, 2026* This is a great fertilizer. Some people don’t like to use this inside because of the slight fishy smell. As for me, It is worth it. ## 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.tn/products/1332115-neptunes-harvest-fish-and-seaweed-liquid-fertilizer-2-3-1](https://www.desertcart.tn/products/1332115-neptunes-harvest-fish-and-seaweed-liquid-fertilizer-2-3-1) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-19*
