Seaweed is one of the best gifts you can give your garden as it has long term positive effects on your soil and your plants. Seaweed meal is a ground and concentrated alternative to adding fresh seaweed to your garden, it is dry and easy to handle and store.

Seaweed meal contains:

Alginate gels vastly increase the microbial population in your soil. Soil health and plant growth are directly proportional to the concentration of soil microbes, large microbial populations mean larger, healthier plants. Alginates also absorb large quantities of moisture which increases moisture retaining capacity of your soil. Alginate is present in seaweed meal at levels of between 16 and 26%.

Growth Hormones and Biochemical Compounds
Seaweed meal contains a range of beneficial plant hormones and biochemical compounds. The plant hormone cytokinin promotes plant cell division and growth thereby increasing yield. Cytokinin has also been shown to strengthen plant immune systems making them better able to cope with pests or disease.

Insoluble Carbohydrates
Insoluble carbohydrates in seaweed meal acts as a soil conditioner (improves aeration & soil structure, especially in clay soils).

Seaweed meal:
Increases yield.
Improves germination.
Increases uptake of soil nutrients.
Increases resistance to pests/insects.
Increases resistance to frost.
Is 100% Organic

Cleared the last of the veg (and weeds) from our raised beds. Into the fourth year now and need to replenish soil. This was the best all purpose option for adding to soil now, very easy to sprinkle over beds. Looking forward to good crops next year.

i love this garden feed because its made from seaweed and is absolutely brilliant for everything that grows. Its has a sweet smell so no funky smell in your garden after applying. Plus it does wonders for your soil. Whats not to love. Since started using it, my trees, shrubs and flowers have given their all in beautiful flowers and healthy foliage. Whats not to love.

Hi there, I am looking for an organic fertiliser for fruit bushes and trees and don't want to keep reapplying (like with liquid seaweed). Is this product and a bit of homemade compost suitable for fruiting bushes and trees or more suitable for ornamental plants? Thanks, Sandra
Answered by Megan
on February 25th, 2019
Hi Sandra - this mix would definitely be suitable for this application, however we would make recommend that you make sure not to spread it too close to the trunk, we would say at least 1 foot away. Thanks, Meg - Quickcrop
Asked By Kirsten

Hello, I would like to add a boost to the garden now in the form of an organic fertiliser that I can spread over the surface of large areas and that will then breakdown and feed from spring onwards. Does this product do that? Would it be good for an allotment as well as ornamental areas? In the past I've used bonemeal for this job but don't feel comfortable using animal products anymore. I work in several gardens and would like to recommend an alternative product to clients who are a bit 'old school'....

Hi Kirsten The Seaweed meal is excellent but it sounds more like you need a slow release fertiliser so i would recommend from the same family Seafeed Organic manure pellets which are actually the Seaweed meal mixed with Organic chicken manure in pellet form. This product is applied at a rate of roughly 1 handful per square metre and will wash down gradually through the soil and is excellent for bringing on areas where the soil and plants need a boost Regards Niall Quickcrop
Asked By Martin

Hi Niall, I have a large collection of chilli plants nearly ready for planting out in the greenhouse, before I do so I wanted to give them a boost with the seaweed. I have a 25kg bag of it bought last year, and I want to make a small amount, say one litre, of the seawweed in water mix to feed them with. How much of the powder should I put in one litre of water for seedlings? Many thanks Martin
Answered by Niall
on April 16th, 2018
Hi Martin Two decent size handfuls per litre but to be honest you don't need to mix it. If you put it on the soil after you have planted them then each time you water you will slowly wash the nutrients down to the roots which is actually better Niall Quickcrop
Asked By Maggie

Hi Andrew, I noted the description says this product helps germination. Does that mean it can be used with seed compost? How would you use it for germination, would it have to be dissolved in water? Thank you!
Answered by Niall
on April 13th, 2018
Hi Maggie You just mix it through the seed compost. As it is slow release it also helps warm the soil for germination purposes and it is not to strong so that when the plants create their first roots it doesn't burn the roots as other feeds might. Regards Niall Quickcrop
Asked By Rebecca
on February 06th, 2018
I've just bought some of your seaweed meal, thank you. For adding to pot plants (15cms), can I mix it with water first, to pour it on? And indeed is it of benefit to pots this small?
Answered by Niall
on February 07th, 2018
Hi Rebecca. It is definitely of use in smaller pots. If you are diluting it just be aware that it will break up in luke warm water that little bit faster. Other than that it is fine to do what you are proposing.

Can I use' seafeed' as a lawn feed?
Answered by Niall
on January 02nd, 2018
You can indeed. It actually works really well as a lawn feed. I used it on an area of my lawn that i was having trouble with and it came out really well.

That brilliant! Have just ordered some. How much would you recommend using at the base of the trench Andrew?
Answered by Andrew
on November 22nd, 2017
Hi Tim. I would be more inclined to mix in with the compost as you fill the trench. I would use a good handful per foot of trench.
Asked By Tim Kimbrey
on November 20th, 2017
Can this be used at the base of a trench dug in Autumn and then covered with compost, to enrich the soil over winter prior to planting out Sweet Peas in Spring next year? Would this be of be of any benefit?
Answered by Andrew
on November 21st, 2017
Absolutely Tim. Sounds like a perfect idea as the Seafeed product is a slow release fertiliser and once it is dug in to the ground it will slowly release to the roots of the Sweet Peas in Spring so perfect timing really. You can also just top dress the soil in Spring with them and it will gradually wash down to the roots with the rain on the surface.

How often do i use it for plants in pots?
Answered by Andrew
on May 17th, 2017
Hi Deborah. It depends on the size of the pot but i tend to put one decent handful per pot once in the Spring, once mid summer if it is wet enough to wash it down and once in the Autumn
Asked By Becky Wells
on March 20th, 2017
How often do I use it? Once a year, in March? or more often? Thanks
Answered by Andrew
on March 21st, 2017
Hi Becky. It will feed for 10-12 weeks and can be used anytime there is growth in the garden (no point in Winter), add to the planting hole for most seedlings and as required when plants look like they need a boost. It is a natural product not high in soluble nitrogen so won't burn plant roots if you accidentally over apply.
Asked By Becky Wells
on March 19th, 2017
When do I use the seaweed meal? How often? How much per sq metre?
Answered by Andrew
on March 20th, 2017
Hi Becky. Sprinkle seawed meal on the surface of the soil and rake in. Typical application rates would be 50g per 8 square meters. I hope this helps.

What is the coverage per 14kg bag?
Answered by Andrew
on November 22nd, 2016
Hi Richard. I presume it is a 4kg tub you are asking about. The 4kg tub will easily cover an area of 40 sq metres spread once a year.
