Neptune's Harvest Organic Fish & Seaweed Fertilizer Description

  • Organic

Neptune's Harvest Organic Fish/Seaweed Blend Fertilizer gives you the best of both products with a perfect blend of fish hydrolysate and seaweed, ensuring a complete fertilization program.

Growers using our fish/seaweed blend fertilizer on a regular basis have reported increased marketable yields and improved shelf life on fruits and vegetables. Fish and Seaweed are known to build the natural sugar in plants. Flowers and foliage will be stronger and more colorful. Blooms will be more plentiful, fragrant and longer lasting.


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) per gallon of water. Feed vegetables, flowers, trees and shrubs every 2-3 weeks. Apply until soil is saturated or 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 gallon of water every 2-3 weeks.

Seed Germination: Soak in solution of 1 teaspoon per cup of water.

Caution: Keep out of reach of children. Do not take internally.

I am pleased with the product.
Works well on orchids

5 Star Rating

I use this in addition to the Michigan State fertilizer for my orchids. I mix 18 tsp of this to 2c of my premixed MSU fertilizer and let it roll through my orchid medium. My orchids have done very well. While this fertilizer does smell you use very little this bottle will last a long time and the smell dissipates within a few hours of watering.
Best plant fertilizer ever

5 Star Rating

I was trilled to find Neptunes Harvest Fish and Seaweed Fertilizer not only on line and in the gallon size but at a very reasonable price with free shipping I will certainly purchase from My Natural Market again.
