Your lawn doesn't hibernate. It deteriorates.
While you're inside with the heating on, moss is quietly spreading across your grass. Frost is weakening the roots. Rain is washing away the last of the autumn nutrients.
By March, most people aren't maintaining their lawn. They're rescuing it. Patchy, yellow, half-moss, half-grass. Starting from scratch when they should be admiring the results.
Unless you do something about it now.
Shake. Soak. Succeed.
Three steps. Five minutes. Done until spring.
Shake
Scatter the granules evenly across your lawn. No spreader needed. Just you and the bag.
Soak
Water it in or let the rain do the work. The granules dissolve and get to work within hours.
Succeed
Moss blackens in 24 hours. Grass greens up in 2 weeks. You do nothing else until spring.
Moss Killer
Iron sulphate complex that turns moss black within 24 hours. No raking required — it breaks down naturally and your grass grows through it.
Selective Weed Killer
Targets broadleaf weeds while leaving your grass completely unharmed. The weeds curl, yellow, and die. Your lawn fills the gaps.
Slow-Release Winter Feed
Controlled-release nitrogen and potassium that feeds continuously for months. Builds root strength and cold tolerance right through to spring.
Bought separately, you'd spend £40+ on a moss killer, £30+ on a lawn weed treatment, and £25+ on winter fertiliser. That's nearly £100 in products, three separate applications, and three weekends outside in the cold.
Or: one bag, one application, from £59.99.

Quick Answers
"Is it safe for my dog?"
Completely. Once watered in (or rained on), it's safe for pets and children. We designed it that way because we have dogs too.
"What if there's a hard frost after I apply it?"
Good. That's literally what this is for. The slow-release formula is engineered to work through frost, rain, and snow. Your lawn still feeds even when the ground is frozen.
"Do I need a spreader?"
No. Shake it from the bag. That's the whole point of "Shake, No Rake."
"When will I see results?"
Moss starts blackening within 24 hours. You'll see a visible green-up within 2-3 weeks. Full results build over 6-8 weeks as the slow-release nutrients do their thing.
"What if it doesn't work?"
Then you get your money back. Every penny. 60-day guarantee, no questions asked. Keep reading.
Green Lawn or Your Money Back
Try it on your lawn for 60 days. If you don't see greener grass, dead moss, and fewer weeds — or if you're unhappy for any reason — contact us and we'll make it right. If we can't, you get a full refund. No questions. No hassle. No risk.
Complete the Set
Your lawn needs different things at different times of year.

Winter treatment works best when applied October–February, while grass growth is slow and moss is actively spreading. Apply now and your lawn enters spring in the strongest possible condition. Wait until March and you've missed the window — you'll need our Spring Treatment instead.

Easy to apply and does what it says on the packet
One bag split but was sent a new one
. Ben using this for a couple of years, definitely keeps the moss away and graas looks good
Delivery arrived fine but not had a chance to use yet
Spread it a few weeks ago before the snow. Moss is gone, never had any weeds but seems to be working fine
Used it twice
The moss is gone and the grass is thick and green.
Dos what it says
Good stuff ben using Good Grow products for a bit now. Good service and always answer qiuck
Greener and weed/ moss free but not seeding well at the moment.
I wish I’d took a before picture. I just wanted to share with you the results of your lawn protection I used this year for the first time!
Our little lawn had never looked to healthy, usually battling with weeds of which covered the lawn up to about 75%.
This years lawn is fantastic!
Decent. Fast delivery, mission accomplished.
Great results once well watered in. He has a Factor who provides grass cutting services and all it does is deposit other people’s weeds. His grass is now emerald green and no dandelions. Got to work on clover snd buttercups bect
This is a good product. I moved house last year and the new lawn was full of weeds and moss almost to the point where I contemplated replacing it, it was a mess.
Some weeds die off faster than others. I had to give the lawn a lighter second treatment a few months in, but finally I have a weed free garden.
Sadly, it doesn't stop my dog peeing on the lawn and killing off patches, but I do have a nice thick, dark green, weed free lawn.
The moss went black but it's been 3 days and nothing else has happened
After winter last year the grass wasn't looking very good, it was full of weeds, yellow and patchy, so I mowed the lawn, gave it few days and applied this.
It's been 4 days and ,y grass is already greener, I can't say about the weeds yet but the moss is dying.
UPDATE: The weeds in the grass died after a few weeks, haven't seen any new ones grow and it's still green.
All good, thx
Worked good in the spreader.
Fat delivery and good service when questions asked
This got rid of most of the weeds & moss in my lawn but there was a few stubborn ones that had small yellow flowers and another one with small mauve flowers. When I told "goodgrow" they sent me some more and now I am sure my lawn will be weed free.
The customer care was excellent.
I am beyond happy with the results. To my surprise, grass seeds which I had planted just a few weeks after application has germinated and is growing well.
The lawn has thickened up significantly and no longer browns up after very short mowing. (I have been using a very old hover mower which we have had for over 10 years, the blade is warped and blunt yet the grass still holds up).
I truly cannot recommend this product enough.
My lawn usually looks terrible this time of year, but this winter treatment worked wonders. The moss turned black within days and the grass is actually green again! Highly recommend.
Removed moss and weeds and encouraged more thicker greener grass
Arrived and killed moss
Cane quick, grass is greener, moss is gone
Great thx x
So far so good. Only started using 4 days ago - when I knew rain was imminent. The grass does seem to look greener
Brilliant stuff. Loved the 'shake, no rake' application it saved me so much hard work. It cleared up the weeds and gave the lawn a real boost despite the cold weather.
Miss gone
Took ages to get it, excuse was it's a northern Ireland address, refunded!
I don't have the energy I once did so when I seen this product it seemed ideal, I was sceptical at first but after a few days my grass was greener and the weeds started to die, to my surprise the grass grew where the weeds once were and now my lawn is just grass, super product and excellent customer service when I needed it
My grass was looking yellow and sad, but this brought it back to life. The weeds are dying back and the colour has returned. Great product for winter maintenance
Finally, a winter treatment that doesn't require back-breaking raking! I just shook it over the lawn and let the rain do the rest. The moss is gone and the grass looks greener already
I was skeptical about treating the lawn in winter, but this stuff works. It cleared up a heavy moss problem in under two weeks and the bag covered my whole back garden easily.
