Winter Lawn Treatment

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. 3-IN-1 FORMULA One Bag. Three Problems Solved. Kills moss. Kills weeds. Feeds your lawn. All winter long. Just shake it on and walk away. Shake. Soak. Succeed. Three steps. Five minutes. Done until spring. 1 Shake Scatter the granules evenly across your lawn. No spreader needed. Just you and the bag. 2 Soak Water it in or let the rain do the work. The granules dissolve and get to work within hours. 3 Succeed Moss blackens in 24 hours. Grass greens up in 2 weeks. You do nothing else until spring. VALUE STACK What You're Actually Getting Three products in one. One application. One price. INCLUDED 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. INCLUDED Selective Weed Killer Targets broadleaf weeds while leaving your grass completely unharmed. The weeds curl, yellow, and die. Your lawn fills the gaps. INCLUDED 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. Don't Take Our Word For It Real results from real customers. Read all the reviews ↓ 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.

Good service and always answer qiuck 6 months ago Keith Reviewer 4/5 Greener and weed/ moss free but not seeding well at the moment. 6 months ago Reply 1 Chelsey Store manager Hey Keith, give it 4 weeks after applying before adding new seed & make sure the temperatures are good ( a hard frost will kill seedlings or make seeds go dormant) 1 Paul Reviewer 5/5 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! 1 year ago Reply 1 Chelsey Store manager Awesome review, thank you Graham Wallace Reviewer 5/5 Decent. Fast delivery, mission accomplished. 1 year ago Gerard Reviewer 5/5 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 1 year ago Reply 1 Chelsey Store manager The clover and buttercup will be gone after a cut or two. Thank you so much for the lovely review 1 Thomas Beck Reviewer 5/5 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. 1 year ago Reply 1 Chelsey Store manager Thomas thank you so much for the lovely review, much appreciated �� Charles Reviewer 3/5 The moss went black but it's been 3 days and nothing else has happened 1 year ago Reply 1 Chelsey Store manager Please wait, the moss going black is totally normal - almost certain you'll be happy within 30 days �� 1 Emma V Reviewer 5/5 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. 1 year ago Reply 1 Chelsey Store manager Thanks for the update Emma Cheryl Reviewer 5/5 All good, thx 1 year ago Susan Reviewer 5/5 Worked good in the spreader. Fat delivery and good service when questions asked 1 year ago Richard Reviewer 5/5 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. 1 year ago 1 Sean Reviewer 5/5 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. 1 year ago Reply 1 Chelsey Store manager Lovely review thank you, you should wait at least 4 weeks before planting seed but glad it worked out! David M Reviewer 5/5 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. 1 year ago Reply 1 Chelsey Store manager Thank you for the kind review David Tony Reviewer 5/5 Removed moss and weeds and encouraged more thicker greener grass 1 year ago Paula Reviewer 2/5 Arrived and killed moss 1 year ago Reply 1 Chelsey Store manager Thanks for the lovely review Luke G Reviewer 5/5 Cane quick, grass is greener, moss is gone 1 year ago Sheila Reviewer 5/5 Great thx x 1 year ago Barbara Reviewer 4/5 So far so good. Only started using 4 days ago - when I knew rain was imminent. The grass does seem to look greener 1 year ago Sarah P Reviewer 4/5 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. 1 year ago Zack Reviewer 5/5 Miss gone 1 year ago Siobhan Reviewer 1/5 Took ages to get it, excuse was it's a northern Ireland address, refunded! 1 year ago Reply 1 Chelsey Store manager I'm sorry about the troubles you faced with your order. Our courier changed due to Brexit rules, we refunded your order and shipped again, hopefully you will update your review once you receive/use the items Kieran Reviewer 5/5 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 2 years ago Gary Reviewer 5/5 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 2 years ago James Reviewer 5/5 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 2 years ago Lisa Reviewer 4/5 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. 2 years ago
