When to use
How to use
- Press down the yellow spout and slide back the green over-cap.
- Flip the spout over.
- Walking at a brisk pace of 1.5m/second, invert the dispenser so that the spout points towards the ground and the granules flow freely.
- Maintain the spout at a comfortable height above the ground (at least 45cm). Spread across the lawn area in even strips. Avoid overlapping. When you stop walking raise the spout to stop the flow of granules.
Maximum individual dose: 35g of product per square metre.
Any other advice?
Mowing: Avoid mowing the lawn 2-3 days before and after treatment. Do not use the first 4 mowings after treatment for mulching. They will be safe to use after being thoroughly composted for 6 months.
Watering-in: If no rain falls within 2 days, water the lawn thoroughly so that the lawn food starts to work.
Staining: Do not walk on the lawn until the product has been watered in and has fully dried, since moss killer can cause stubborn brown stains on clothes, paving slabs, etc. Brush off immediately if accidentally spilt.
What about children and pets?
If no rains falls within 2 days, water the lawn thoroughly so that the lawn food starts to work. Children and pets can use the lawn once the granules have been watered in and dried.
Where to use
Miracle-Gro® Complete 4 in 1 can be used around trees in the lawn, but avoid contact with foliage. It can also be applied where bulbs are growing in the lawn, provided it’s applied after all the bulb foliage has died down naturally. Avoid drift onto flower beds and other neighbouring plants.
How often to apply
To be applied a maximum of twice a year with a 3 month interval in between.

A2: Your lawn will be greener in 1 week, the moss will blacken and need to be raked out after 2 weeks and full weed control will take 3 to 5 weeks.
Q3: How do I get the best results using Miracle-Gro® Complete 4 in 1?
A3: For best results and even greening we advise using one of our lawn spreaders, application can be done by hand but this does require measuring out each square metre and ensuring 35g is applied evenly over the area.

A4: Overseeding or reseeding patches can be done 8 weeks after using Miracle-Gro® Complete 4 in 1. After applying new seeds, Miracle-Gro® Complete 4 in 1 must not be applied until the grass is 6 months old.
Q5: I’ve over-applied Miracle-Gro® Complete 4 in 1, what should I do?
A5: If you over-apply the product at a rate several times that advised on pack, you may see areas of browning, this is where the excess Nitrogen has scorched the blades of grass. Usually the roots are fine and will re-grow providing the patches are kept moist and no further products are applied.

Decent all in one lawn treatment.

I tried Miracle-Gro Complete 4 in 1 on my lawn this past spring after hearing mixed things about it. I was mainly looking for something that could deal with the moss patches and weeds that had built up over winter while also giving the grass a bit of a boost.Application was pretty straightforward. I followed the instructions carefully especially since I’d read that using too much could scorch the grass. It took a bit of time to apply evenly but the process wasn’t difficult.After a couple of weeks I did notice the lawn looking greener and a bit thicker. Some of the weeds started to disappear and the moss reduced noticeably though not completely. I wouldn’t say it transformed the lawn overnight but there was definite improvement.One thing I did find is that it really needs to be used at the right time—ideally with some rain or watering afterward. On a drier spot where I didn’t water as much the grass looked a little stressed. So it’s not exactly foolproof and you do need to be a bit careful with how and when you use it.Overall I think it’s a decent product if you're looking for an all-in-one lawn treatment and are willing to follow the instructions closely. It worked fairly well for me though I wouldn't call it a miracle—more of a helpful boost if your lawn needs a bit of everything.

Cheaper more efficient alternatives

I was really happy to try this as our new build garden is diabolical at the moment. I followed the instructions and was hopeful but I was really disappointed. Not sure if it just didn’t take to the garden or not but the only difference i seen was dandelions are now dying off. That’s the only weed thats changed. The lawn looks no healthier though it states thicker healthier lawn. I don’t really suffer with moss so unsure how effective that would be. We are rife with mile a minute sprouting up throughout the garden which has been caught up when the garden was laid clearly. Overall i have used spray weed killers that have worked the same as this just need to find something else that will help get rid of the mile a minute and whatever other weed like plants are growing around the garden.
Brilliant for a nicer lawn.

I’ve recently used Miracle-Gro 4 in 1 and it’s probably too soon to judge the final results. Right now there are quite a few yellow dead patches which is a bit concerning. Hopefully it’s part of the process and things will improve with time. Feeling cautious but hopeful!
Not the best product
Reviewed on
The size of the box and the amount of product you receive is great and did our whole front garden. We liked the application of the box as it spread the product widely and ensured all parts of the garden were covered. However the product did not have too much of an effect on the weeds. It took several days to get into the soil even with nights of rain. Overall it hasn’t been very effectively and for the price I wouldn’t say it was worth it.
Lush

Have never used this before so I’m grateful to be able to try this. We have an allotment and we used it around the pathways as they are full of weeds bits of moss here and there and after a couple of weeks of using the grass is looking a lot more lush than it was. So would definitely recommend miracle grow 4 in-1 lawn care Treatment as it’s perfect for anyone looking to feed their grass kill weeds moss and to make your lawn lush and green again. Thank you Influenster.
Good for killing moss and greening up grass

We have a lot of oak trees in our garden so with shadowing the moss thrives. This product has worked well in greening up the grass and killing the moss in an easy to use container. We’re yet to see a vast improvement on the weeds but it just may be too soon..

I’ve been using Miracle-Gro Complete 4 in 1 for a few weeks now and it’s made a noticeable difference to my lawn. It tackles everything at once—feeds the grass kills weeds controls our moss. I found it easy to apply (just follow the instructions carefully) and within days the grass looked greener and healthier. The weeds started to curl up and die off and even the moss patches are thinning out. It’s a powerful product so make sure to measure properly and avoid over-applying. All in all a reliable all-rounder that lives up to its promises - definitely worth having in the shed if you want a lush healthy lawn.
Miracle-Gro Complete 4 in 1 for your lawn

Miracle-Gro Complete 4 in 1 lawn treatment. I've tried it before and had good results so I was happy when I got to try it again thanks to Influenster. I have a decent size garden. Now that summer is on its way I want my lawn to look its best. The treatment is in the form of granules that you spread evenly onto the grass. I use a pair of garden gloves when I use it as it's a chemical. In order for the Miracle Grow to do its work you need to water the grass if it doesn't rain after a day or two. It then gets rid of weeds and moss. It takes a few weeks for your grass to start looking great so be patient. I would recommend this product.

I was asked to test this Roundup miracle gro complete 4 in 1 in exchange for an honest review. The product came extremely well packaged and has very clear instructions on how to use it. The packaging makes it easy to use and I was very impressed with the quantity for the price. It was easy to spread and despite having a fairly large garden there is enough left for another application later in the year. We are looking forward to seeing the results now. Thank you for letting us test.

The results of the Miracle Gro 4 in 1 are just starting to take effect although I think it’ll be a good month before I see the final results. It was very easy to use walking up and down distributing the granules was very easy with the applicator head on the tub. I made sure to remove the thatch build up beforehand and to water the next day. The moss is starting to turn dark and my grass it looking green and growing quite fast. Fantastic product I even have some leftover to do the front lawn this week

Having received this product to test I have used it on my garden lawn and awaiting to see the results. The design and application nozzle make it easy to apply to the affected areas and there are clear instructions on how to use which is good to ensure proper application. I am looking forward to seeing the long term results of the grass as my garden does suffer with patches and weeds but on first glance it’s working. Hopefully this does the trick! The bottle is a good size too and can get multiple uses out of it. Would recommend.
