Powder-coated for added durability. Review: This is an excellent product... a little on the pricey side but works great. Review: 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! ## Features - Grow a beautiful vegetable garden - Flowers and foliage will be stronger and more colorful - Blooms will be more plentiful, fragrant and longer lasting - Easy to mix and apply by hand, sprayer, or drip line ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000IS780Y | | Brand Name | Neptune's Harvest | | Coverage | Aprx. 8000 sq feet | | Customer Reviews | 4.8 4.8 out of 5 stars (1,514) | | Global Trade Identification Number | 00081435240094, 00781147946030 | | Item Form | Powder | | Item Type Name | Hydrolized Fish & Seaweed | | Item Weight | 4.54 kg | | Liquid Volume | 3784 Milliliters | | Manufacturer | Neptune's Harvest | | Mixing Ratio | 1:128 | | Model Number | FS191 | | Specific Uses For Product | Plant Growth | | Target Species | plants | | UPC | 781147946030 081435240094 745682292878 | | Unit Count | 128 Milliliters | ## Product Details - **Brand:** Neptune's Harvest - **Item form:** Powder - **Item weight:** 10 Pounds - **Liquid volume:** 3784 Milliliters - **Specific uses for product:** Plant Growth ## Images ![Fish & Seaweed Fertilizer 2-3-1 (Gallon) - Image 1](https://m.media-amazon.com/images/I/71bkx0dbtUL.jpg) ## Questions & Answers **Q: how often to apply** A: Directions for Fish, Blend and Seaweed LiquidsDirections: Shake well before using. Prepare for one application only. Do not store diluted fertilizer.House Plants: Use 1 tablespoon per gallon of water. Feed every 2-3 weeks. Do not over water.Outdoor Plants: Use 1/8 Cup (1 fl.

The longer the product is stored, the better you'll have to shake it up. **Q: I like the looks of the reviews but, the smell wouldn't bother me if it works, will it attract bears and raccoons?** A: This is the hydrolyzed fish and seaweed Mix. It doesn't smell bad when you first mix it up, just be sure to use it all at one time. I mean make small batches like a gallon at a time or quart. Use it all don't let it sit in a container. It then will stink! I haven't had any problems with wildlife. The only thing that might attract is flies. **Q: Where does the fish come from? I am trying to avoid pacific fish because of the Japanese power plant melt-down** A: This is what it says on the bottle and their website: "Neptune's Harvest is a division of Ocean Crest Seafoods Inc., established in 1965 as a wholesale fish and seafood company. Still today, our Neptune's Harvest Organic Fertilizer gets made from fresh caught North Atlantic fish right on the docks of Gloucester, MA. Unlike a fish emulsion,our fertilizers are produced using a unique cold process "without cooking out all the good stuff". Best of all, it works great on everything that grows!"So it's a Massachusetts fishing industry byproduct! :) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by I***R on 24 May 2025* This is an excellent product... a little on the pricey side but works great. ### ⭐⭐⭐⭐⭐ Review *by C***Y on 2 March 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.
