Seafeed Seaweed & Poultry Manure Plant Feed & Natural Fertilizer

N.P.K: 4-3-3

We all know chicken manure pellets are an excellent source of nitrogen for the plants in our vegetable garden. Nitrogen is the element responsible for green, leafy growth and so is what you want for crops like cabbage, cauliflower, broccoli, kale and spinach. Seafeed goes a few steps further by mixing free range poultry manure, fish, seaweed and humic acid to create the best natural fertilizer pellet available. This is the best all round natural pellet fertilizer we're come across and is a vital part of our garden toolkit, highly recommended. Seafeed was formerly available on our site as Seamungus.

Seafeed undergoes a unique composting process which has been designed to stabalise the nutrient content and to maximise the availability of those nutrients. The finished pellets are guaranteed free of any pathogens, parasites and weed seeds.

Vegetable plants take a lot of nutrients form your garden soil and as we remove the vegetables and eat them very little of these valuable elements are returned to your garden. The benefits of adding organic materials to your garden are well known with seaweed being recognised as one of the top performers. Seaweed contains naturally occurring growth stimulants as well as a very broad range of essential minerals and trace elements which are used in the growth of strong, healthy plants.

We Supply our Seafeed plant food in 2 different size buckets; 4kg and 12kg. Please choose the required one using the Bucket Size Tab above.

Why is seaweed so beneficial?

Seaweed has been used for centuries by Celtic and Scandinavian people as a soil improver, in fact in many cases (the Aran Islands off the West coast of Ireland for example)  the soil has been entirely built on a seaweed base.

The sea is very rich in minerals and as the seaweed grows it absorbs minerals in its plant tissues which are then released and made available to plants when the seaweed is broken down. Scientists have found in seaweeds a veritable soup of plant-growth stimulants, vitamins, chelating agents, trace minerals, enzymes, and amino acids, all of which influence the growth of plants in different ways.

Studies have shown that seaweed can produce dramatic results in plants including 40 percent increase in yield from cucumbers and potatoes. Plants have been seen to have better frost tolerance, increased seed germination and a greater ability to absorb trace elements. Plants also seem to suffer less transplant shock because of the growth hormones contained in seaweed so handy as a liquid feed before planting out vegetable seedlings.

Seaweed for your garden - in easy to use pellets. I bought Seafeed with chicken manure, after reading about the benefits of putting seaweed onto your vegetable plots and borders. I went for the 12kg bucket, as it offered great value, and offering enough pellets to do all the areas I need without running out Easy to apply, virtually odourless, so far, so good. Obviously the proof will be in how the plants themselves perform next season. I'm confident that this will be a product I come back to using, throughout the year...

Hi I am considering your 1.8m raised bed with Coir. How many tubs of this would I need to add to get the correct nutrients ?
Answered by Niall
on April 10th, 2019
Hi Lesley The Coir already has nutrients added to it so 7 bales of the coir will be sufficient to fill the 1.8m Vegtrug and be good to plant in to straight away Niall Quickcrop

A few years ago, I researched the constituents of Seamungus. If this is the same product with a new name - is the 'Amino Acid' part still being sourced from coal?
Answered by Andrew
on June 14th, 2018
Hi Kevin. No, the Seafeed product is made from composted seaweed and free range poultry manure only. It does not contain coal sourced humic acid.

Asked By Mike Harris

what percentage of the product is seaweed, how much chicken manure and how much fish meal?
Answered by Andrew
on April 18th, 2017
Hi Mike. The ratio of chicken manure to seaweed is approx 70% manure and 30% seaweed meal. The product does not contain fish meal.
Asked By KR

Hello, I have had mine since last year with the lid on tightly but I have opened it and the pellets are still mostly separate but they are a bit mouldy/furry. is it still ok to use?
Answered by Andrew
on March 20th, 2017
Hi KR. Yes, the seafeed is still fine to use in the garden. Molds develop most often when there is sufficient moisture and a lack of air, so common in bagged compost and/or manure.
Asked By Tiffany

Is the seaweed/fish material ethically sourced, how is it sourced, and where from? Where is the chicken manure sourced from and is it from organic/free range chickens? If not, what are the conditions in which the chickens are raised?
Answered by Andrew
on May 10th, 2016
Hi Tiffany. Good questions. The fish meal is the waste from the fish factories in North Donegal Ireland and is all from registered fish factories. As regards the ethics of fishing i will leave that one up to you. The chicken manure is from free range farms but not Organic. I am afraid for a farm to be registered Free range the chickens only have to be allowed outside on grass for 1 hour a day so again not 100% sure on the ethics of that. I can't imagine there is any product on the market that ticks all of the ethics boxes which is a shame but this is the closest we can find.
