These are the secrets I’ve been looking for! I’ve just used liquid fertiliser for the first time and I’m amazed at the results but also a little disappointed in how much of it I’m going to need if I want to keep treating my 700 square meters of lawn. Will for sure be looking into making my own mixture for next time.
Thanks a lot for your nice videos! Totaly appriciate it! Just started with my own lawn 3 month ago and this as well as your other videos really helped me a lot to get me a nice lawn without breaking the bank :).
Nice tips. I grew my lawn from seeds and was amazing. I had my first cut 2 weeks ago and some of the grass parts started to be a bit yellow. I overseeded the empty patches and will do the second cut this weekend. Shall do what you advised in this video after I gut the grass? Thanks 😊
Spot on Robbie. Use Collier already but it’s great to know where to get the products from. Shame we cannot get the seaweed from the vendor you visited recently.
Hi Thank you so much for your excellent advice.i bought the ammonia sulphate and the sulphate of iron.I also used turf sol. Wow,just wow amazing results.Thank you so much. Keep up the fantastic videos.regards Paul😅😅😅😅😅😅😅😅😅😅😅😅
That was a brilliant video. Ive measured my lawn and watering can. Now I thought my can was 5L. It turns out to be 7.5L. I was getting my calculations all wrong. Im going to give this ago. Cheers Robbie. 👍👽
Hi Robbie, here's a conundrum for you. I took the top sod of my rear garden rotovated and reseeded in a dwarf rye. I dug out an old french drain running down centre of garden filled up with sods turned upside down and put 300mm of topsoil on top. What's happened is where the old shore is evergreen and sits out like a sore thumb. It's down 6 weeks and haven't applied fertiliser. Will the shore eventually settle down and tone in the same as the rest? Thanks
The cat's out of the bag with this one Robbie. Great insider secret. Ive only ever tried the ammonia with seaweed but think ill give the iron a go with it. The fertiliser folk will be after you now 😂
This is a fertilizer used on a LOT of golf greens. It's cheap as chips and works really well 😁 If someone watched this and wanted to be an entrepreneur, they could bottle this up and sell it on eBay for 💰💰💰

Thank you for all the helpful tips and advice you give, its always much appreciated! I want to put some putting surfaces into my lawn for a bit of fun for the kids and grandchildren, can you advise on a grass seed that is specifically for putting surfaces?
hi, Robbie, Thank you for sharing. I learn a lot from your videos. As you can tell, I am a beginner who tries to catch up and I am still watching your videos that you uploaded months ago. I look into the Elixir product which recommends 20-35g/sq m. The 25kg bag you talked about in the video only needs 2.5g/sq m. this is 10 times difference. As you mentioned too much fertiliser will cause issue in the water downstream, I wonder whether I shall stick to your 2.5g or use the manufacturer's 25g? appreciate for your advice. cheers Rod
Hi Robbie. Great video. We have one acre and use a walk behind boom sprayer. We use ammonium sulphate as we have a high ph. Can I ask are we ok to mix the ammonium sulphate, iron sulphate and seaweed sulphate in the same batch. Secondly, how often can we reapply. Thanks again big man

Hi Robbie Would you be able to break down the usage in a simple month format? (best guess) The usage information on collier turf suggests not to use in the summer months (although I am this year (however we've had plenty of rain & not so much heat this year).

Like button smashed! Fortunately, ammonium sulphate is readily available in 25kg bags on the German Amazon site for about €22. What is the difference between using ammonium sulphate instead of urea (46-0-0)?
Hey Mike good question. Ammonium sulfate and urea both provide plants with nitrogen. Urea needs to go through a process called hydrolysis in the soil to release nitrogen for the plants. This process takes some time. On the other hand, ammonium sulfate already contains nitrogen in a form that plants can use immediately. Ammonium sulfate also contains sulfur, which is good for plant growth. Urea doesn't have any additional nutrients You could use urea for this too
@@Premier_lawns_official Thank you, Robbie! I have been using urea at about one-quarter the application rate with my bi-weekly seaweed extract doses, but am at the point where I'm ready to order another bag. I'll try the ammonium sulfate.
No matter how well I mixed it and filtered it I found that the Prokleen Iron sulphate blocked the filter on my sprayer every few minutes. Tend to use the liquid stuff now. More expensive but far less frustrating.
If you can find Phydrion paper strips or a ph meter ( it is pricey for a useful one. ) check your water and if it is over 6.5 add a bit of citric acid, mix it up well and handle it with care. Check again. Not to much! If the solution is acidic, the iron sulphate remains in solution, in alkaline water it becomes iron oxide ( rust ).

Birchmeier Aquamix 1.25 and a makita sprayer will do their job. 75% Lolium perenne (perennial ryegrass) 15% Festuca rubra (red fescue ordinary) was the mixture. See you next!
Hi Robbie, Great advice thank you. Also I’m thinking of buying an electric Scarifyer/aerater instead of hiring a petrol one each time. Are the electric ones any good? I’m looking at the 1800cc Hyundai
Different times of year have different amounts of growth. In the summer months when the grass is actively growing you will need to put it on more often It will also depend on how much you cut the grass too You could use this instead of a granular or you could use this to get an extra bit of colour...
The thing about liquid feeds, it gives you a lot of control about what goes on. 100 percent you could use this and only this. The golf course use only this... During the growing season you might have to put it on once a month or more. Depends on the growth, what height you cut and and how often...
Today after watching this fantastic advice I got the ammonium sulfate and seaweed liquid delivered. I have a Stihl backpack sprayer that holds 17 litres. How much seaweed and ammonium should I use to water as I'm useless at maths trying to work it out is a nightmare? Hope you will be able to help me out. Cheers 👍
Hi Robbie. I have used this method on our 4500 sqm lawn using a boom sprayer. Great results. I have two questions. 1, how often would you apply and 2, iron ? You have previously said ‘limit iron application to 4 times per year’. Is this different to previous references?
That sounds like a nice lump of a lawn! It would be great to see some pictures, I have a group on Facebook, and I will link it below In the past, I have said to limit it to 4 applications, however, since then I have spoken to numerous groundsmen up and down the country and they all say that on their greens etc they have been applying iron on monthly applications for years. So there are different thoughts out there on how often you should, the place where I was taught this mix, they use iron 12 months of the year once a month for years.... It's one of the best golf courses in Ireland We filmed the seaweed video there - Ballyliffin GC The facebook group, come and join us - facebook.com/groups/premierlawnscommunity
@@Premier_lawns_official thanks Robbie. I will sign up and post some pictures. We have had quite a journey and look forward to sharing. Your videos have been pivotal to our progress. ‘ every days a school day’
Sorry Robbie. One more question…. A lot of the data sheets advise weekly (seaweed) or two weekly (ammonium sulphate). If we are treating once a month is there any supplement feed in between ? Cheers Dan
@Niveko_nightmare the golf course only use this. But they are bent greens on a links course and they want them lean If you have a rye grass lawn then to get more body then you probably want to mix in some granular feeds too. Especially in spring
Hi Robbie… great vid as normal and tips! What can I feed my lawn with.. I’ve just got new seed coming through but I’ve used fertilisers and damaged em. Could I use a high Nightrogen feed on it? Keep the vids going … great advise
Hi mate I have all the calculations for the products and water qty for the ammonium Do I add the full qty of iron to the water qty for the ammonium? Only use 6l in total so do I still add 1/2g per metre of the lawn into the 6l? Help would be appreciated
I love your videos so much I smashed the subscribe button. Watched this but can’t get my head around your application rate of 2.5g per sq mtr of sulphate of ammonia when packaging on almost all of this product states 25g per sq mtr. I’m confused
Liquid fertilisers are taken up by the plant right away. That is why the amount needed is much lower. If you put on more it would burn So, if you use a liquid you see the results much faster as it gets into the lawn right away On the other hand, a granular takes a while to break down and become available to the plant And it's not all available right away, it might take a few weeks or even months for it all to get released.
This looks fantastic. One thing I can't work out though is the water. The issue I have is that both the seaweed and Ammonium are added to a similar amount, only 50/60ml water per metre squared.. The iron though needs about a litre per metre according to the packet. So for a 100m lawn you'd only need 5/6 litres water to apply the seaweed and ammonium, but the iron you'd need 100 litres! So my question is how does one manage to use all three combined when the water requirements are so different?
The instructions you are looking at are for a watering can. For a sprayer you don’t need to use no where near that amount of water. For 100m2 I’ve used 6 litres of water at the max rate and been absolutely fine
So I have a question..... I had a lovely 20 year old Laburnum tree and I also have a cherry blossom a Canadian maple and also at the time I had a native mountain ash I bought some powder in a tub that kills moss and I sprinkled it on the lawn..... Don't ask what it was as it was a good few years ago..... It was sprinkled evenly.... And within a few months the laburnum tree was dead as a dodo I left it there for two years just to be sure but it never came back..... All other trees were OK.... Are laburnum trees susceptible to what ever is in moss killer or do you know?????
Good question, yes I'm sure you could. But the question should really be should you? 100 per cent the seaweed and iron, maybe leaving the Ammonia until the new seed gets established Fertiliser should display the which indicates the percentage of nitrogen (N), phosphorus (P), and potassium (K) Look for a starter fertiliser with a higher P or K number Ammonia is the (N) For new grass you want something that has plenty of (p) or (k) Ammonia doesn't have any of those. Slow-release nitrogen sources, such as polymer-coated or organic-based fertilisers, are beneficial for newly seeded lawns. They release nutrients gradually over time, providing a steady supply of nourishment without overwhelming the young grass. This helps prevent excessive growth or burn damage.
Hi robbie so after the drama i had getting caught at the weekend think have raked the black an that out cut it sitting not bad.. can i put iron down soon for a good green up. Or just get the seaweed onto it?
Yes bought all 3 products on your recommendation. Great video as I have been buying granular fertiliser and prices are going through the roof! Keep up the great work.
Love the vids! So this gives you nitrogen and you add seaweed extract and iron... but no need for the P and K in NPK then??? Real noob wants to know what to put on in spring, in summer and autumn by way of mix.... ;-)
The golf course where I filmed about the seaweed only uses sulphate of ammonia, sulphate of iron and seaweed in the spring, summer and autumn In the winter they take the sulphate of ammonia out of the mix Depends on what you want, if you want to learn about lawn care, it's about trying out different things and seeing what works best for you. You can try this for yourself or / and add it into a program for your lawn. If you want to learn a bit more about npk watch this video ua-cam.com/video/DiimZB3r4mA/v-deo.html If you want why seaweed is good, this is a longer video, a deep dive into seaweed, partly filmed at the golf course mentioned in this video ua-cam.com/video/6JcgKNjUqRE/v-deo.html
Thanks, yes I'm from northern Ireland, just outside Belfast Most folks struggle to understand me. I had to put on English subtitles for the English viewers 😜
Hi Robbie great video. Just to clarify you would mix the items separately with their own water rate then dump them in the same sprayer? Then add the seaweed dose to the final amount in the sprayer? So say you have 10litres of the mixed product in the sprayer you then add the correct dose of seaweed for the 10 litres? No extra water for the seaweed?
After a few weeks my original grass would be over 12 inches long. I overseeded in May and mowed 2 weeks later using a cheap rotary, on a fairly high setting. Now mowing at usual height on my cylinder..4 weeks after overseeding. I just couldn't leave it any longer as visually it would look awful going into summer.
Hi, like other comments I appreciate you video but am struggling with the quantities. Per 100m sq Ammonium Sulphate, 250gms diluted in 6 litres. That’s ok Iron Sulphate, 200gms diluted in 100 litres. This is the one that puzzles as that’s a lot a backpack fills when you have a garden of 1,000 Sq m. Just checking that’s correct. The other question is can the products be mixed, for example (100sq m) can I add the 250gms AS to the 200gms IS and if so do I combined the water amounts? Thanks
The application rate for iron is based on area of lawn and the amount of water is incidental. Work out volume of water needed to pass over the lawn three times and add the total m2 application rate for your lawn to this amount of water.
The Sulphate of iron for green up, states 1-2g per m2 and says to mix in 1lt of water per m2. So for a 100 m2 lawn it would be 100-200g in 100lt of water?! That’s a lot of refills of my knapsack! in the video you mention the 1-2g rate but now the water amount. Can you advise please? Cheers mate.
The water rate is 600l per hectare / 10,000m2 for the product I showed If you are struggling watch this video next as it dives deeper into how to do the calculations ua-cam.com/video/NIIVETuKDek/v-deo.html
Cheers Robbie. Not struggling with the calcs, just in the video you were talking about the calcs for the ammonia and then went on to the iron and just said it’s 1-2gr per m2 but didn’t mention water rate per m2 and had a bit of a shock when I got the tub and it said 1lt water per m2 whic would be 148ltr of water….that would of been a lot of trips in my knapsack!? 😂 keep up the good work 👍🏻
Hi Robbie! All the other ammonia sulphate brands I've seen state an application rate of 35 g/m² every 4-6 weeks, how come this is only 2.5 g/m² when they are also NPK 21-0-0?
@@Premier_lawns_official But that doesn't change how much nitrogen is going on to the lawn, does it? it's still 21% of 2.5g compared to 21% of 35g per square meter? Sorry if I'm missing something.
Good question, hopefully this answers it for you Liquid fertilisers are in a dissolved or suspended form, which makes the nutrients readily available for plant uptake. The nutrients are immediately available in a soluble form, allowing plants to absorb them more efficiently. Granular fertilisers, on the other hand, need to dissolve and break down in the soil before the nutrients become available to plants. As a result, granular fertilisers are typically applied at higher rates to compensate for slower nutrient release and lower overall nutrient availability
@Premier_lawns_official I never used it, a bit new for me. But if I may ask. Let me say you use those 3 product's. Do you spray them all every time, or do you skip some product's from time to time.
Wow Robbie £60 for Higgi ammonium sulphate, I can get 25kg of Higgi ammonium sulphate for £25 & that includes shipping, Coullier turf has added a huge markup on that!.
Wow, that's even cheaper than my supplier (he doesn't do postage) I did a quick Google search and this came up, I phoned them and asked would they post to NI... If you want to post the link here I will add it to the video description 👍
@@woodpecker80 you won’t find it on Amazon for that price, I will try & find out where I got it (bought it last year) only thing is UA-cam always deletes any links I post, maybe I could disguise it some how.
I'd be interested in having a look. The cheapest I can find in the UK is Elixir garden supplies @ £41.99 for 25kg. However with a 60m2 lawn i'd be still using it decades from now. They do a range of sizes & i've been using it as a granular for the past month. I plan on trying to apply as a liquid as described in this video & the previous one. Once the lawn looks like it needs a top up i'll give it a go.

Excellent advice. How often would you suggest applying this, and is this instead of all granular products?
Different times of year have different amounts of growth. In the summer months when the grass is actively growing you will need to put it on more often
It will also depend on how much you cut the grass too
You could use this instead of a granular or you could use this to get an extra bit of colour...
@@Premier_lawns_officialas a ball park for general lawns which has kids playing on it a lot! How many times a year should I apply it?
@@Premier_lawns_officialmany thanks. So as an additional green up in the summer could I use monthly or is more frequently still ok?
The thing about liquid feeds, it gives you a lot of control about what goes on.
100 percent you could use this and only this.
The golf course use only this...
During the growing season you might have to put it on once a month or more.
Depends on the growth, what height you cut and and how often...
Today after watching this fantastic advice I got the ammonium sulfate and seaweed liquid delivered. I have a Stihl backpack sprayer that holds 17 litres. How much seaweed and ammonium should I use to water as I'm useless at maths trying to work it out is a nightmare? Hope you will be able to help me out. Cheers 👍
Hi Robbie. I have used this method on our 4500 sqm lawn using a boom sprayer. Great results. I have two questions. 1, how often would you apply and 2, iron ? You have previously said ‘limit iron application to 4 times per year’. Is this different to previous references?
That sounds like a nice lump of a lawn!
It would be great to see some pictures, I have a group on Facebook, and I will link it below
In the past, I have said to limit it to 4 applications, however, since then I have spoken to numerous groundsmen up and down the country and they all say that on their greens etc they have been applying iron on monthly applications for years.
So there are different thoughts out there on how often you should, the place where I was taught this mix, they use iron 12 months of the year once a month for years.... It's one of the best golf courses in Ireland

@@Premier_lawns_official thanks Robbie. I will sign up and post some pictures. We have had quite a journey and look forward to sharing. Your videos have been pivotal to our progress. ‘ every days a school day’
@Niveko_nightmare great to hear, 100 percent. Always nice to learn new things 😁
Sorry Robbie. One more question…. A lot of the data sheets advise weekly (seaweed) or two weekly (ammonium sulphate). If we are treating once a month is there any supplement feed in between ? Cheers Dan
@Niveko_nightmare the golf course only use this. But they are bent greens on a links course and they want them lean
If you have a rye grass lawn then to get more body then you probably want to mix in some granular feeds too. Especially in spring
Hi Robbie… great vid as normal and tips!
What can I feed my lawn with.. I’ve just got new seed coming through but I’ve used fertilisers and damaged em.
Could I use a high Nightrogen feed on it?
Keep the vids going … great advise
Adding more fertiliser might damage them some more!
Maybe some seaweed
@@Premier_lawns_official hHi Robbie… many thanks 🤓
@@Premier_lawns_official Sorry Robbie would this iron harm the new seedlings ?
Thanks for your reply’s🤓
It depends on how old the seedlings are.
@@Premier_lawns_official there about 3 weeks old….
question then ,, how often would you spray a lawn with this ( once a week , once a fortnight ,once a month ) ?
The golf course does it once a month, it will also depend on how much it grows. The downside with liquids is that you are cutting it off each time
Hi mate
I have all the calculations for the products and water qty for the ammonium
Do I add the full qty of iron to the water qty for the ammonium?
Only use 6l in total so do I still add 1/2g per metre of the lawn into the 6l?
Help would be appreciated
It should be all there for you, this video also covers it
ua-cam.com/video/NIIVETuKDek/v-deo.htmlsi=HN5HieoYxKMtO7Y7
I love your videos so much I smashed the subscribe button.
Watched this but can’t get my head around your application rate of 2.5g per sq mtr of sulphate of ammonia when packaging on almost all of this product states 25g per sq mtr.
I’m confused
Liquid fertilisers are taken up by the plant right away. That is why the amount needed is much lower. If you put on more it would burn
So, if you use a liquid you see the results much faster as it gets into the lawn right away
On the other hand, a granular takes a while to break down and become available to the plant
And it's not all available right away, it might take a few weeks or even months for it all to get released.
Wow really impressed with the answer and how quickly it came Robbie. Much appreciated !!!
@@ianbeaman7166 👍
This looks fantastic. One thing I can't work out though is the water. The issue I have is that both the seaweed and Ammonium are added to a similar amount, only 50/60ml water per metre squared.. The iron though needs about a litre per metre according to the packet. So for a 100m lawn you'd only need 5/6 litres water to apply the seaweed and ammonium, but the iron you'd need 100 litres! So my question is how does one manage to use all three combined when the water requirements are so different?
Same question here
The instructions you are looking at are for a watering can. For a sprayer you don’t need to use no where near that amount of water. For 100m2 I’ve used 6 litres of water at the max rate and been absolutely fine
@@philgornalllovely stuff
@@philgornall at last some Info 👍🏻
So I have a question..... I had a lovely 20 year old Laburnum tree and I also have a cherry blossom a Canadian maple and also at the time I had a native mountain ash I bought some powder in a tub that kills moss and I sprinkled it on the lawn..... Don't ask what it was as it was a good few years ago..... It was sprinkled evenly.... And within a few months the laburnum tree was dead as a dodo I left it there for two years just to be sure but it never came back..... All other trees were OK.... Are laburnum trees susceptible to what ever is in moss killer or do you know?????
I'm sorry, I don't know to be honest. Not for forte
Amonia Sulphate safe to use on a newly overseeded lawn?
Good question, yes I'm sure you could. But the question should really be should you?
100 per cent the seaweed and iron, maybe leaving the Ammonia until the new seed gets established
Fertiliser should display the which indicates the percentage of nitrogen (N), phosphorus (P), and potassium (K)
Look for a starter fertiliser with a higher P or K number
Ammonia is the (N)
For new grass you want something that has plenty of (p) or (k)
Ammonia doesn't have any of those.
Slow-release nitrogen sources, such as polymer-coated or organic-based fertilisers, are beneficial for newly seeded lawns.
They release nutrients gradually over time, providing a steady supply of nourishment without overwhelming the young grass.
This helps prevent excessive growth or burn damage.
Hi robbie so after the drama i had getting caught at the weekend think have raked the black an that out cut it sitting not bad.. can i put iron down soon for a good green up. Or just get the seaweed onto it?
If you want some green and no black put less iron in 👍
Thanks robbie appreciate it
👍👍
Hi Robbie
Can I spray Ammonium Sulphate and Ferrous Sulphate together at the same time.
Cheers
Yes, of course, some seaweed too. Go for the magic mix
Yes bought all 3 products on your recommendation. Great video as I have been buying granular fertiliser and prices are going through the roof!
Keep up the great work.
@@billholden1181 prices were starting to come down and then Russia stopped the grain deal, so now they are going back up!
Love the vids! So this gives you nitrogen and you add seaweed extract and iron... but no need for the P and K in NPK then??? Real noob wants to know what to put on in spring, in summer and autumn by way of mix.... ;-)
The golf course where I filmed about the seaweed only uses sulphate of ammonia, sulphate of iron and seaweed in the spring, summer and autumn
In the winter they take the sulphate of ammonia out of the mix
Depends on what you want, if you want to learn about lawn care, it's about trying out different things and seeing what works best for you.
You can try this for yourself or / and add it into a program for your lawn.

When adding the products together do you need to add all the water amounts together as well?
Yes, follow the water rate 👍
Hi Robbie great video. Just to clarify you would mix the items separately with their own water rate then dump them in the same sprayer? Then add the seaweed dose to the final amount in the sprayer? So say you have 10litres of the mixed product in the sprayer you then add the correct dose of seaweed for the 10 litres? No extra water for the seaweed?
How soon would you recommend mowing an overseeded lawn please?
I always recommend leaving it for a few weeks
After a few weeks my original grass would be over 12 inches long. I overseeded in May and mowed 2 weeks later using a cheap rotary, on a fairly high setting. Now mowing at usual height on my cylinder..4 weeks after overseeding. I just couldn't leave it any longer as visually it would look awful going into summer.

I don't understand your question
sorry was asking strengh of iron
Like smashed
Thanks 👍👍👍
Hi, like other comments I appreciate you video but am struggling with the quantities.
Per 100m sq
Ammonium Sulphate, 250gms diluted in 6 litres. That’s ok
Iron Sulphate, 200gms diluted in 100 litres. This is the one that puzzles as that’s a lot a backpack fills when you have a garden of 1,000 Sq m. Just checking that’s correct.
The other question is can the products be mixed, for example (100sq m) can I add the 250gms AS to the 200gms IS and if so do I combined the water amounts?
Thanks
Lee watch this video, it should really help you
ua-cam.com/video/NIIVETuKDek/v-deo.html
The application rate for iron is based on area of lawn and the amount of water is incidental. Work out volume of water needed to pass over the lawn three times and add the total m2 application rate for your lawn to this amount of water.
Hello Robbie wanting to try this mix but worried about how safe it is for dogs conflicting info on the internet
A bit of common sense goes a long way, it should be safe as long as you keep the dog off it for a while
If it's a pup or eats grass, then a bit longer
Hi Robbie great video.
Can I put new grass seeds down in September or should I wait until the spring.
As its so damp at the moment, I would have a go at it now
@Premier_lawns_official Thanks for the advice Robbie i will give it a go.cheers
What does the sulphate of ammonia do to the grass ?
Provides nitrogen and sulphur nutrients. Also, burns the grass if you overapply and/or not water it to wash it down from leaves
The Sulphate of iron for green up, states 1-2g per m2 and says to mix in 1lt of water per m2. So for a 100 m2 lawn it would be 100-200g in 100lt of water?! That’s a lot of refills of my knapsack! in the video you mention the 1-2g rate but now the water amount. Can you advise please? Cheers mate.
The water rate is 600l per hectare / 10,000m2 for the product I showed
If you are struggling watch this video next as it dives deeper into how to do the calculations
ua-cam.com/video/NIIVETuKDek/v-deo.html
Cheers Robbie. Not struggling with the calcs, just in the video you were talking about the calcs for the ammonia and then went on to the iron and just said it’s 1-2gr per m2 but didn’t mention water rate per m2 and had a bit of a shock when I got the tub and it said 1lt water per m2 whic would be 148ltr of water….that would of been a lot of trips in my knapsack!? 😂 keep up the good work 👍🏻
@@ryant5016 Using Robbie's calculations of .06 litres of water per metre squared, you'd need 6 litres of water on a 100 square metre lawn.
So with the iron you would add 100/200g to the 6 litres of water?
Great video but if I use these three products, how do I kill weeds as none of them do that I assume ?
No, use a weed killer separately 👍
@@Premier_lawns_official Which one works Robbie ? Most seem to do nothing . Thanks
This is a secret recipe used by groundsmen and greenkeepers up and down the country. It definitely works
Hi Robbie! All the other ammonia sulphate brands I've seen state an application rate of 35 g/m² every 4-6 weeks, how come this is only 2.5 g/m² when they are also NPK 21-0-0?
This is soluble. Your meant to spray it on
@@Premier_lawns_official But that doesn't change how much nitrogen is going on to the lawn, does it? it's still 21% of 2.5g compared to 21% of 35g per square meter? Sorry if I'm missing something.
Good question, hopefully this answers it for you
Liquid fertilisers are in a dissolved or suspended form, which makes the nutrients readily available for plant uptake.
The nutrients are immediately available in a soluble form, allowing plants to absorb them more efficiently.
Granular fertilisers, on the other hand, need to dissolve and break down in the soil before the nutrients become available to plants.
As a result, granular fertilisers are typically applied at higher rates to compensate for slower nutrient release and lower overall nutrient availability
@@Premier_lawns_official That's a brilliant answer, thanks very much!!
@@AESamuel happy to help 😁
Is the formula in the video correct? Don't you divide the 25kg (25000g) by 10000 to get kg/m2. Not the other way round.
How often can I apply in the summer and winter bud
It's answered in the video
I genuinely can't find that part bud, also do you mix both products in the sprayer or apply them individually thank you
Together. Less in the winter as the grass doesn't grow as quickly
In the summer, when you need to. Probably 1 a month, try it and see how you go.
@@Premier_lawns_official thank you so much bud will reply with results
How much of the seeweed per sq meter?
It should say on the container
@Premier_lawns_official I never used it, a bit new for me.
But if I may ask.
Let me say you use those 3 product's.
Do you spray them all every time, or do you skip some product's from time to time.
Good job, not vor Germany.😁

Wow Robbie £60 for Higgi ammonium sulphate, I can get 25kg of Higgi ammonium sulphate for £25 & that includes shipping,
Coullier turf has added a huge markup on that!.
Wow, that's even cheaper than my supplier (he doesn't do postage)
I did a quick Google search and this came up, I phoned them and asked would they post to NI... If you want to post the link here I will add it to the video description 👍
Definitely send the link … I can’t find it on Amazon for that price.
@@woodpecker80 you won’t find it on Amazon for that price, I will try & find out where I got it (bought it last year) only thing is UA-cam always deletes any links I post, maybe I could disguise it some how.
I'd be interested in having a look.
The cheapest I can find in the UK is Elixir garden supplies @ £41.99 for 25kg. However with a 60m2 lawn i'd be still using it decades from now.
They do a range of sizes & i've been using it as a granular for the past month. I plan on trying to apply as a liquid as described in this video & the previous one. Once the lawn looks like it needs a top up i'll give it a go.
@@Premier_lawns_official I posted a link to another brand which is cheaper, but my post has been removed for some reason
