## Description

desertcart.com : Neptune's Harvest Fish & Seaweed Fertilizer 2-3-1, 18 Ounce (1 Gallon) : Fish And Seaweed Fertilizer : Patio, Lawn & Garden

Review: Big Yields, Beautiful Plants, Fair Price - My tomatoes and herbs love it. So do my houseplants. I love it for two reasons: One, it helps me get big vegetable yields and grow beautiful plants. Two, it's all natural. As for the price, it's fair. Not the cheapest fertilizer on the market, but it's worth every penny.
Review: Love this stuff - I think this is a great organic fertilizer that can be used throughout your garden whether your plants are in the ground, potted, or indoors for seedlings or established plants. I highly recommend it. All of my plants love it and it is not harsh on any of them. Definitely follow the instructions on the bottle. The key for me is to not water the plants right before. If it is for potted plants and depending on the size I do little by little. Then after I finish I will go back to the first one to see if it needs more. You don't want the fertilizer draining out of the bottle - you want to make sure it all stays in the soil. This is fermented fish and seaweed so the concentrate in the bottle does have a punch as expected but once it is diluted there is barely any smell or any off putting smell. That is also why I do little by little so the fertilizer does not drain down into the drip trays. I can see it making the smell stronger as it evaporates.

## 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

## 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. Oz.- 1:128) pergallon of water. Feed vegetables, flowers, trees and shrubs every 2-3 weeks. Apply until soil is saturatedor as a foliar feed until leaves are wet, top & bottom.It is best to foliar feed early or late in the day.Lawns: Use 1 gallon concentrate mixed with sufficient water to cover 8000 sq. ft. Feed monthly during growing season and again in the fall.Compost Enhancer: Use ¼ Cup (2fl. Oz.) per gallonof water every 2-3 weeks.Seed Germination: Soak in solution of 1 teaspoon percup of water.Caution: Keep out of reach of children. Do not takeinternally.

**Q: what is the shelf life**
A: From the manufacturer's website FAQ - Our liquid fertilizers have an indefinite shelf-life, until water is added. Always shake well before use. 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! :)

### ⭐⭐⭐⭐⭐ Smells TERRIBLE, but highly effective!
*by J***A on January 9, 2026*

I got this to pretreat garlic before planting. Smelled so gross (like fish LOL duh). However, every single garlic bulb planted has sprouted. It surely did not disappoint me!
