Benefit
Description
Nutrient-Rich Formula
Seaweed, specifically Ascophyllum nodosum, is packed with 77 minerals, 17 amino acids, complex sugars, and chelating agents. Combined with high-quality Humic and Fulvic Acid, this nutrient-rich solution boosts soil health, helping plants thrive. Kelp is a vital soil enrichment product that promotes healthy plant development, making it ideal for lawns, trees, and garden plants.
Improved Soil Health
Seaweed improves soil structure and fertility by enhancing moisture retention, aeration, and drainage. This leads to healthier root systems and better nutrient uptake, fostering stronger plants.
Enhanced Plant Growth
The growth-promoting hormones in liquid seaweed stimulate plant growth, resulting in increased leaf and stem growth, improved flowering and fruiting, and overall plant vigour. It helps boost plant development, making it an essential addition to any garden or lawn care program.
Stress Tolerance
Seaweed extracts contain natural compounds that help plants endure environmental stresses, including drought, heat, cold, and disease. These compounds boost plant resilience, helping them recover from adverse conditions and thrive.
Increased Nutrient Absorption
Seaweed's organic compounds act as chelating agents, improving the availability and absorption of nutrients, ensuring your plants get the maximum benefit from the soil. This leads to more productive and healthier plants.
Disease & Pest Resistance
Seaweed extracts enhance the plant’s natural defences, making them more resistant to diseases and pests. It helps reduce the need for chemical pesticides and fungicides, promoting a more eco-friendly approach to plant care.
Environmental Sustainability
Liquid seaweed is a sustainable, eco-friendly fertiliser derived from renewable marine resources. It does not contribute to water pollution and helps maintain beneficial soil organisms, making it a safe and responsible choice for your lawn and garden.
Safe for Humans and Pets
Seaweed extracts are non-toxic and safe to use around humans and pets. There is no need for protective clothing or equipment when applying, making it a user-friendly solution for your garden care needs.
Seaweed Secrets is more than just a fertiliser – it’s a soil conditioner that enhances the long-term health and fertility of your garden and lawn. By improving soil structure, increasing moisture retention, and supporting beneficial soil organisms, Seaweed Secrets creates an ideal environment for plants to thrive.
The Science Behind Seaweed Secrets
Seaweed Secrets is based on the synergistic action of cold-processed kelp extract, humic acid, and fulvic acid, acting as natural biostimulants and nutrient chelators. It works by:
Stimulating root zone microbes to convert bound nutrients into plant-available forms
Improving Cation Exchange Capacity (CEC) in the soil, aiding nutrient retention
Enhancing stress tolerance through cytokinin and auxin compounds naturally found in seaweed
Supporting nutrient absorption across a wide pH range
Strengthening plants’ natural defence mechanisms, reducing reliance on synthetic pesticides

This seaweed secrets product does work wonderfully well for all plants and lawns you only need to use what the instructions say and it keeps your plants and gardens safe and healthy from disease and pests just what the good doctor ordered.Thank you Plant Doctor
Not fit for purpose
By: David on 9 March 2025
It doesn't matter how good the product is, the container it comes in is unusable. I ended up using a drill and transferred half the product into an old Bunnings Seasol container. At least I can get the product out of the Seasol container. I am sick of the dumb stuff and this item is not fit for purpose. Just Rubbish! And the fact that the other reviewers don't mention this is highly suspicious
Super Happy

Cornerstone of liquid program

Awesome stuff
Simply the best !
By: Tim on 12 March 2021
I started using seaweed products over 10 years ago and like most started with Seasol, but soon learnt that there was better products out there. I then progressed to Natrakelp which I instantly noticed the difference. Trying Seaweed Secrets has moved things up another level again. I believe Seaweed Secrets is the best value product on the market with much better additives than the competition.
Fantastic
By: Warren on 5 March 2021
One of the many fantastic Plant Doctors products I use fortnightly throughout the growing season. Soil health has improved greatly.

By: Mason on 26 February 2021
I bought a bulk order of the ben sims pack which included this product and a variety of others. I Have been very satisfied this season with the results. Grass has handled the temperatures well with the assistance to plant doctors foliar products. The turf looks great and loves the applications. At a competitive price, i highly recommend.
Awesome product
By: David on 20 February 2021
After using other products for a while know I have noticed the difference in just a few short weeks of using this product. Maybe it's a secret ingredient?

Sensational mix
By: Tyler on 4 January 2021
I purchased the Ben Sims Lawn Tips pack for my instant turf couch and all of the products have been sensational. The improvement in my couch at a former residence, in which I did not use these products, and the couch at our new place, in which I use these products, is 10 fold. Very happy.
Bulk is the way to go
By: Nathan on 23 December 2020
Moving over from Seasol this product will allow me to apply more often and still save $$$ the 20ltr Works out so much better than my regular Seasol and with added Humic & Fulvic its a clear winner.
So worth it for the price!
By: Nathan on 9 December 2020
After trying other seaweed products over the years, I bit the bullet and tried this product , and actually saw the difference! I will never go back!
Thanks plant doctor!

Great health tonic for plants
By: Benjamin on 27 November 2020
I use this throughout my garden and apply extra bits on parts of the lawn that need that extra love. I find that some pots that don't have a lot of soil and require frequent watering seem to get stressed more than others (probably from flushing nutrients away) and giving some of this in the watering mix greatly helps them.
BETTER THAN SEASOL
By: Bruno on 25 November 2020
I COULDN'T RECOMMEND THIS PRODUCT ENOUGH, MUCH BETTER THAN SEASOL AND BETTER VALUE FOR MONEY IF ORDERED IN BUNDLE WITH OTHER PRODUCTS
Special Mix Product 2.
By: RON on 17 November 2020
This is another of the products that I use in my Special mix. I have started using the EZFLO Fertigation System and now realise that I should have been doing this ages ago. So much less work and I am sure will give better results.
Outstanding
By: Scott on 15 November 2020
I have been using seaweed secrets on my lawn since my reno in September. I cannot recommend this product enough - it has definitely helped improve the health of my lawn.
Value For Money and a Great Product

This is great stuff, use it on my lawn and all plants. Really good results.
Great all-rounder
By: Steve on 23 October 2020
Seaweed Secrets is a great product. The added humic and fulvic acids make this a better option than other common seaweed solutions (seasol). It is also less viscous and won't clog your sprayer. Can also be mixed with other liquids, such as fertiliser and wetting agents.
Amazing value
By: Adrian on 14 October 2020

Versatile organic tonic
By: Jerome on 27 July 2020
I won't lie, this stuff stinks!! But there's plenty of goodness in there and I've seen far greater results from this that other Seaweed products available at chain stores. I've used it as a foliar spray and also mixed in a watering can, both which result in great plant growth. Particularly useful on veggie gardens.
Great replacement for seasol
By: Gary on 26 July 2020
A much more economical way to add seaweed product to your lawn. Works great!
Highly recommended
By: Michael on 22 July 2020
I wouldnt go anywhere else - stop searching for alternatives. Ordered my product and had them delivered within 48 hours (for free!!) Very helpful team and support to finding the right solution for my needs. Great experience as well as value for money and can’t wait to see the results of the products. I did a lot of research and came to the conclusion that PD products are the way to go. Plus supporting a local business make it the purchase even better. Thanks guys!
No odour. Great formulation!
By: Ken on 9 July 2020
There are many seaweed products I have tried and this guys really did an amazing mix with their formula, my plants are loving it & I am loving the odorless mixture in my hydroponic system. Great stuff!! This product will go well with their fulvic acid for foliage;
Seaweed Secrets
By: Michael on 2 July 2020
Absolutely love this stuff, I use it on the lawn & plants and noticing the condition of them already improving. Certainly helps with the resistance to temperature changes. Will definitely be getting more of this stuff.
Best seaweed solution I've used - great value and super fast postage too.
So much better than Seasol
By: Kassem on 24 June 2020
Ive been using this product in combination with some other PD products and ran a small experiment on my hedge. On one part of the hedge i used this and other PD products, on the other part of the hedge i used slow release fertiliser and some seasol. The difference is amazing. I wish i could have posted photos here to show how vibrant and full the hedge is using the PD products as opposed to normal fert and seasol. Such an astounding difference.
Great product
By: Stephen on 24 June 2020
Fantastic product at a reasonable price.
Excellent
By: Aaron on 21 June 2020
Seaweed secrets is a cut above the rest. After seeding a couch lawn in late summer I can say this stuff is the reason for its strong establishment hands down. Have been applying 2-3 weekly with quantum H and the lawn is still going strong in winter!

A lawn must
By: Samual Anderson on 5 January 2020
Seasol on steroids. Easily the best single product to buy if on a budget, alot of benifits and important ingredients all in one.
No Secret
By: Shane on 19 December 2019
Well I've been telling everyone about Seaweed Secrets, it's a keeper for sure
Super product
By: shafan monsoor on 12 December 2019
I am not a expert on lawn care but thanks to Seaweed Secrets my tif tuff lawn is the envy of the neighbourhood.
Great product

Was told to try some from a work mate after only using seasol, much better product overall soil health has improved, and this product works out to be cheaper than I was buying seasol anyway. Very easy decision
Great Product.

Good Stuff!
By: Aaron on 1 November 2019
Really helped strengthen my lawn after a reno and got it growing again.
Started showing results really quickly, and I love the bottles :)
Seaweed Secrets
By: Jack Deen on 23 October 2019
It makes sense to go a more 'commercial grade' product like seaweed secrets over something like Seasol from Bunnings. It is easy to use and to be honest you can't use too much of it. My plant health has been strengthened through using this product, and the root zone of my plants has grown significantly.
Great product, very impressed!
By: Nathaniel on 2 October 2019
Primarily purchased this to include some extra Humic and Fulvic acid in my lawn care routine. I’m now using this to replace Seasol due to the many added benefits and superior results at a lower application rate. Works out cheaper too! Saw results within 48 hours, grass is looking super green, would highly recommend.
Fantastic
By: Alexandra on 22 September 2019
Never seen my lawn look more green. Highly recommend this product
Great Product
By: Aaron on 20 September 2019
Great product, I used to use seasol from Bunnings but this is wayyy better value for essentially the same stuff (probably even better)!

dont let the title mislead you, im not feeding it to my dog... however the root build that this has help create, my dog isnt destroying my lawn nearly as much anymore, very happy
Great all rounder
By: Kris on 24 August 2019
Has been great for improving overall health in newly seeded perennial ryegrass. Great value for money!
Best seaweed condition around.
By: Rhys on 20 August 2019
Been using the competitors for years, after making the switch to this product there will be no turning back. Fantastic product all year round.
So Good!
By: Tom on 19 August 2019
Can't believe how cheap this product is. It outperforms all other major competitors. I am more than happy to use this organic product if I only have to wait a few days for shipping. Will definitely be ordering more in the future
Great product
By: Brett on 11 August 2019
Fantastic organic product that has produced better results that any other product that i have used previously.
A Must Have
By: Giang on 8 August 2019
I use to use Seasol but this product is way better. It's organic and even cheaper than Seasol. Best product you can buy at this site which is saying a lot as they have many great products, but I would say this is an absolute bare minimum for anyone that loves their lawn. 6 star product
Sorry Bunnings
By: robert on 2 August 2019
Such good value!! Sorry Bunnings, I’m not buying Seasol ever again.
great product
By: scott on 31 July 2019

Love seaweed secrets over seasol impressed with the results
Awesome product
By: Shannon on 3 June 2019
So much better value then anything from the green shed.
Superior product
By: Jacob on 18 May 2019
I've tried other seaweed based solutions before and initially they all seemed to do the same job. Then I tried seaweed secrets and noticed how much better the results were in a smaller timeframe. Seaweed secrets is a superior alternative to the stuff available at your big box stores. Hands down.
who needs Seasol?
By: Sean on 30 April 2019
100 times better than seasol, no stick , full of goodies and superb for mixing into a nice hot mix for the sprayer back. SS,ACTIVE8, stimulizer and your lawn will continue to thrive. excellent product!
Great value
By: Rebecca on 25 April 2019
Much better value than Seasol. Great for improving our poor quality soil. Highly recommended.
Great first product
By: Jason on 18 April 2019
I started off with seasol from Bunnings which was ok, then found the lawntips YouTube page which point to plant doctor and my lawn has never looked better. Seaweed secrets is the next step up to a better lawn.
Best on the market
By: Shayne on 11 April 2019
This is my favourite product. I naturally have poor quality soil and by using a small amount of this every week, my lawn health has improved out of sight.
My Neighbors are Jealous
By: Kevin on 7 April 2019
I have just started using Plant Doctor products and the results are fantastic.

By: Paul on 27 March 2019
Amazing results is all I can say. Compared to Seasol this product is head and shoulders better for results and value for money!!!
Awesome stuff
By: Matthew on 23 March 2019
This stuff is awesome, really noticed the difference to lawn health since I started applying it. Highly recommended!
The bees knees
By: Jonathan on 21 March 2019
Really impressed. Better results than major branded competition, need less of it, the 1L came in an easy to measure bottle and as far as value for money, smashes all of the competition. Extremely impressed!
Leaves seasol in the dust
By: Jennifer on 19 March 2019
I use to use seasol and will never go back. Seaweed secrets is much more potent than seasol so you use less of it. Fantastic value and has taken our lawn to the next level
Fantastic
By: Tyron on 13 March 2019

By: Marckus on 9 March 2019
Couldn't be happier with this product. I'm so glad I found PD. Excellent value for money specially when buying the bundle
You cant beat plant doctor products
By: Dafydd on 23 February 2019
Cheaper and better than the compition, what more do you want? You have to buy this, so easy to use and takes effect straight away
Plant Stress. Challenge accepted!!!
By: Leo on 19 February 2019
This baby is a miracle for plant stress. Been using Seaweed Secrets for a year and my viburnum plants have thrived in awful conditions with clay/alkaline soils. They were stunted in growing and heavily stressed with major leaf dropping. Very stringy. Once i started following the instructions, my plants had started to become healthy and thicken up with growth. SS saved my babies.
Fantastic results
By: Dylan on 7 February 2019
Switched to this product after using seasol for a while and the improvements have been outstanding so far! Definitely a good buy and will see improvements quickly!
Cheaper than anything else on the market, better t
By: Jake on 30 January 2019
Used Seasol for a few weeks since laying my new turf. Thought I was getting good results with it then, until I started using PD Seaweed Secrets. Using this in conjunction with other PD products I think my turf is becoming incredibly hardy to heat stress and generally looks much healthier.
Used this coupled with PD soil wetter & PD fert on a few patches that I killed to straw when I was trying to eliminate Paspalum with a weed killer. That was 3-4 weeks ago. Everything is back to normal now......... already! (sizeable patches too, around 7 square metres).
I'm sure there is all sorts of goodies going on in the soil, but that's way over my head. Turf looks brilliant and its cheaper & better than any other product, need I say more!?
Don’t buy anything else!!
By: Joshua on 17 January 2019
I’ve been using Seaweed Secrets for the past 8 weeks and have noticed a considerable improvement in the growth and health of my lawn. Combined with Natures Soil Wetter and Activ8mate on the lawn it’s a winning combo at very affordable rates - considerably less than even the cheapest products from your local Big Green shed. Do yourself a favour and buy the big drum, you’ll want to use it on everything.
Why use anything else?
By: Martin on 10 January 2019
Loved switching to Plant Doctor range of products, with Seaweed secrets being such a great all round versatile product. Much more economical than other 'brands' but with better results. Both the lawn and plants love it. All seem to hold up so much better through changing weather, and overall health has been fantastic.
Superb formulation
By: Michael on 2 January 2019
Was using Seasol and getting ok results. Once I switched to seaweed secrets it was like chalk and cheese. The lawn seemed to thicken and grown as I was spraying it on. After using this for a few application my kids and dog cant pull the grass blades out as easily and bare areas seem to miraculously fill in. Amazing stuff. Will be putting this down every 2 weeks all year round.
Awesome Product and great results
By: Justin on 24 December 2018
As the title says, this is an awesome product and I have got great results. Since applying this my lawn has taken off. Will def be getting more and making this a staple of my maintenance routine!
Fantastic
By: Lia on 23 December 2018
Perfect all rounder. Use it for both turf and plants. Bigger bottles make life easier and fast delivery
Great Economical Product
By: Emma on 13 December 2018
Fantastic superior replacement to common similar market alternatives. Great results
Seaweed not so secret?
By: Richard on 1 December 2018
Seaweed is a great organic potassium source along with other minerals and such. This product however is very potent and easy to use and mix with Plant doctors other liquids. I apply every 1 to 2 weeks as the more you apply the better the soil becomes conditioned and strengthens turf grass and plants. Buy the larger size than you think you need as you will use this stuff all the time!
Building a better "Mouse Trap"
By: Tony on 30 November 2018
It is well known of the benefits of kelp in plant and lawn care, couple that with Humic and Fulvic Acid and you have a supercharged formula that provides outstanding results. Application rates and frequency are not excessive showing the potency of the product.
Wow what a result
By: Corey on 28 November 2018
Where do i start, great product with amazing results and at such great value. Thankyou
Awesome product
By: Daryn on 20 November 2018
One of the best value for money products I've purchased for my lawn. Used it with the soil wetter and activ8mate products and made a massive difference.
Great value
By: Kom on 19 November 2018
Concentrated stuff so you use less than other seaweed products on the market. Amazing for my new turf, applied weekly and definitely helped it survive being laid in middle of winter.

Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
