  • OMRI ​ORGANIC LISTED SEAWEED & KELP FERTILIZER: Liquid Kelp is a natural plant food that provides a range of benefits for plant health and growth. OMRI listed for organic use, GS Plant Foods Liquid Seaweed Fertilizer is a completely natural, seaweed extract fertilizer for plants. Our liquid seaweed will help stimulate natural root growth, mineral uptake and overall plant growth and vigor. This can be applied to any type of soil or plant without concern for waste or harmful chemicals.
  • ONE OF NATURE’S ‘MIRACLE’ PLANT FOODS: Made from the finest seaweed plant Ascophyllum Nodosum, this is one of nature’s miracle plant foods. Our seaweed extract greatly increases your plant’s resistance to stressors such as excessive heat, wind, drought conditions and more. The seaweed fertilizer for plants will increase the bloom set and size of flowers and fruit. It increases and stabilizes chlorophyll in plants, which results in darker green leaves and increased sugar content in plants.
  • OPTIMAL PLANT GROWTH & HEALTH AT HOME OR COMMERCIALLY: Used in low concentrations, kelp liquid fertilizer acts as an efficacious growth promoter. GS Plant Foods seaweed fertilizer organic is used extensively on a commercial basis, as well as at home for gardeners as an organic soil conditioner. Reduce herbicide use by adding our liquid kelp extract, and yet maintain the same kill effectiveness. Using this seaweed plant fertilizer will lead to healthier crop yields and general plant well being.
  • EASY TO APPLY FOR NATURAL GREAT RESULTS: Apply liquid kelp to improve specific growth stages. To promote additional buds, apply when plants are beginning to bud. To extend the shelf life of fruits and vegetables, spray 10 days before harvesting. To lengthen the life of cut flowers, spray a day or two before cutting. In lieu of trying to catch specific growth stages, apply every 4 to 7 days. This liquid kelp should be sprayed in the morning or late afternoon when the leaves stoma are open.

5.0 out of 5 stars Don't forget to activate your Kelp!
By Ra on August 19, 2019
Kelp benefits greatly from being mixed with a small amount of humic acid and fulvic acid. These act as a catalyst on the Kelp. I read all the reviews and decided on Mr. Fulvic. https://amzn.to/31RS8or It contains both humic and fulvic acids. It got 5 star reviews and it was under $20 for a full 8 ounces, which is lasting forever. I believe that this Kelp, along with the Mr. Fulvic is what allowed these lettuce experiments in passive hydroponics to survive, despite being placed in 100 degree Florida sun when all they had was one tiny root, the thickness of a hair. They went dormant for a week but they survived and they starting growing rapidly two weeks ago. The variety is Parris Island Romaine Lettuce.

Update. Well it's now mid November and I spray a mild Kelp solution on all my plants every morning and afternoon. I always make sure to add the fulvic acid. I have noticed the plants really perk up a few times. I drench the plants and the foliage absorbs it all in just a few minutes.

5.0 out of 5 stars SIMPLICITY and RESULTS FAST with This Kelp Concentrate
By Miracle on July 10, 2018
As Chair Of The Servant Farm I am ordering my 2nd Gallon Of the Gallon Kelp Concentrate to be Used in our Non Profit Volunteer Ministry providing Fresh Produce to Numerous Non Profit Agencies, our Refugee Communities, The Veterans Shelter & our Northwest NC Food Bank since it is so easy to simply Add it to the 3/4 Gallon Tank EZ Flow Fertilization System connected to our (25) Drip Irrigation 100 Foot Lines. It gave all our Vegetable Crops such a Burst Of Energy when Used 10 Days Ago! We have more Produce than We can Harvest! It is a Magnificent product for maintaining the Healthiness Of our 500-600 Plants Under GREAT STRESS with our heat being in the 90s & Up! This is the Healthiest year for our Tomato Plants! We have also used the Fish Emulsion in the same manner, but the graininess of the ground up Fish did not mix with the water in the 3/4 Gallon Tank as Quickly, but I will probably buy it too and simply be patient as the system works! Sending Fertilizer in our Drip Lines Underground reaches the Plant’s Roots and all its Foliage & Vegetables dangling on it! Amazon carries the EZ Flow Irrigator System, Which is Dynamite!
