Fast Growing Grass Seed

Finally—a grass seed that actually fixes the problem You know that bare patch you’ve been staring at all summer? The one where the kids play football. The scorched spot from last year’s BBQ. The bald areas left behind after you killed the moss. They’re not going anywhere on their own. And every week they sit there, they’re an open invitation for weeds, more moss, and that sinking feeling every time you look out the window. Here’s the thing most grass seed companies won’t tell you: Generic “all-purpose” seed isn’t designed for repair work. It’s designed for perfect conditions, fresh soil, no competition, ideal weather. That’s not your garden. Your garden has compacted soil, established grass fighting for resources, and whatever the British weather decides to throw at it. Rapid Repair & Establishment is different. We’ve blended fast-germinating varieties with aggressive root developers specifically for the tough job of filling gaps in existing lawns. This isn’t seed you scatter and hope for the best. This is seed engineered to establish quickly, compete hard, and blend in like it was always there. What you’ll notice: Week 1-2: First shoots breaking through. That bare patch is already starting to look less bare. Week 3-4: Thickening up. The new grass is filling in, roots are establishing, and you’re starting to see real coverage. By Day 30: If you’re not looking at healthy green grass where there was once bare soil, we’ll make it right. That’s our Green in 30 Days guarantee. Perfect for: Bare patches from wear and tear Spots damaged by dog urine Areas left bare after moss or weed removal Worn pathways and high-traffic zones Post-scarification overseeding Any lawn that needs a fresh start in tired areas How to use: Rake the bare area to loosen the top layer of soil Scatter seed evenly, you should still see soil between seeds Gently tread down or rake lightly to ensure seed-to-soil contact Water well and keep moist until established No digging. No complex preparation. Just seed, water, and watch it work. Coverage: Choose your size based on the area you need to repair. A little goes a long way, over-seeding wastes seed and can actually slow results. Your lawn has been waiting long enough. Let’s fix it.

Sowed Good Grow in early September when the rain returned and the bare areas filled in remarkably quickly. The new growth matches the existing grass perfectly. Lawn is looking healthy again heading into autumn. 7 months ago Christopher Ogden Reviewer 5/5 Second chance seed that actually works The product description says if you have tried before and given up this is your second chance. That was exactly my situation. Had a bare strip along the path that I had tried to seed three times with other products. Good Grow finally got grass growing there. Sometimes you just need the right seed for difficult spots. 8 months ago Stuart Holroyd Reviewer 4/5 Germinated in tired old soil Our soil is not great. It has not been improved in years and is fairly compacted. Despite that this seed germinated well and produced healthy looking grass. I think the claim about working on damaged and tired soil is genuine. Certainly better results than I expected given the conditions. 8 months ago Gary Whitehead Reviewer 5/5 Handy to keep in the shed for spot repairs I bought a bag and just keep it in the shed for whenever a bare patch appears. A handful of seed and some regular watering and the patch is gone within a couple of weeks. It is like a first aid kit for the lawn. Very convenient and reliable. 8 months ago Daniel Harwood Reviewer 5/5 Exactly what was needed for a new build garden Our new build came with a garden that was basically rubble with a thin layer of topsoil. Nothing was growing. Good Grow Fast Growing managed to get a lawn started even in those poor conditions. It is not perfect but we went from bare earth to green grass in three weeks which felt like a miracle. 9 months ago Dominic Farrell Reviewer 5/5 Worked on compacted soil where nothing else would grow We have an area by the back gate where the soil is rock hard from years of foot traffic. Tried two other seeds there and nothing took. Good Grow germinated and established even in that awful soil. It is not as thick as the rest of the lawn but there is actual grass growing where there was none before. 9 months ago Amy Sutcliffe Reviewer 4/5 Sorted the bare spots under the trampoline Moved the trampoline and the grass underneath was completely dead. Yellow squares in the middle of the lawn. Raked it over and sowed Good Grow Fast Growing. Two weeks later the squares are green and filling in. Will need one more mow before it is fully blended but the progress is great. 9 months ago Adrian Haslam Reviewer 4/5 Good but not miraculous on heavy clay On our heavy clay soil germination took closer to two weeks rather than the seven days claimed. Still faster than other seeds I have tried but worth managing expectations if your soil is heavy. Once established the grass looks good and is growing in thick. 9 months ago Rebecca Holden Reviewer 5/5 Quick patch repair after dog damage Our dog dug up several patches in the lawn chasing after a mole. Needed a quick fix and this delivered. Filled the holes with topsoil, scattered the seed and within ten days had green growth covering the damage. The lawn looks normal again. Handy product to keep in the shed. 10 months ago Deborah Platt Reviewer 5/5 No colour mismatch at all The thing I appreciate most is that the repaired patches do not stand out. The colour and texture match the surrounding lawn so well that once it is mowed you cannot see the join. Previous seeds I used always left a slightly different shade of green which drove me mad. This blends perfectly. 10 months ago Neil Pemberton Reviewer 5/5 Blends in perfectly with existing lawn My biggest worry was that the repaired patches would look different from the rest of the lawn. Different colour or texture. But this seed blends in seamlessly. After two mows you genuinely cannot tell where the bare spots were. That colour match is really impressive. 10 months ago Karen Livesey Reviewer 5/5 Fixed the goalpost patches My son has football goals on the lawn and the goal mouth areas were bare mud. We lifted the goals, scattered Good Grow and kept him off it for two weeks. The patches are now covered with thick grass that has already survived a few matches. Will need to reseed again eventually but the speed of repair is fantastic. 10 months ago Samantha Rigby Reviewer 4/5 Fast yes but keep it watered The germination speed is impressive but only if you keep the soil consistently moist. I let one patch dry out for a couple of days during a warm spell and the germination was noticeably slower there. The areas I watered religiously twice a day came through in about eight days. Great seed but water is key. 10 months ago Jackie Rowlands Reviewer 5/5 Fixed our bare patches after building work We had builders in and they left several large bare patches across the lawn from their wheelbarrows and materials. Needed something that would fill them in quickly before a family event. Good Grow Fast Growing did the job in about two weeks. The patches are now invisible. Saved us from having to turf. 11 months ago Vanessa Kemp Reviewer 5/5 Great for a quick fix before selling the house We were putting our house on the market and the lawn was letting the garden down. Bare patches everywhere. Sowed this two weeks before the first viewing and the lawn looked presentable by the time the estate agent came round. Did the job we needed at short notice. 11 months ago Terry Goddard Reviewer 5/5 Impressive speed of germination I have used a lot of grass seed over the years and this is genuinely the fastest I have seen. Growth was visible in about a week and by three weeks the coverage was full and even. The grass itself looks healthy and a nice colour. Not just fast but good quality too. 11 months ago Connor Walsh Reviewer 5/5 Visible growth in six days I was sceptical about the seven day claim but I scattered this on a bare patch on a Sunday and by Saturday morning there were green shoots all over it. By the end of week two the patch was fully covered and blending in with the surrounding lawn. Genuinely fast. 12 months ago ⭐ BEST SELLER Fast Growing Grass Seed See results in just 7-14 days ✓ Rapid germination formula ✓ Perfect for patch repair ✓ Green in 30 Days Guarantee Shop Now — Free Delivery �� Free UK Delivery • 30-Day Money Back Guarantee Frequently Asked Questions Q: How much is delivery?A: Free Q: How long does delivery take?A: 1-3 working days Q: How quickly will I see results?A: You should see the first green shoots emerging within 7-14 days under normal conditions. By day 21-30, you’ll have visible coverage in your repaired areas. Full establishment typically takes 6-8 weeks. Q: What’s the best time of year to use this seed?A: Spring (March to May) and autumn (late August to October) are ideal. Soil temperature needs to be at least 8-10°C for germination. Avoid sowing during summer heatwaves or winter frost. Q: How much seed do I need per square metre?A: For patch repair and overseeding, use approximately 25-35g per square metre. For bare soil, use 35-50g per square metre. It’s better to sow slightly less than too much, you should still see soil between seeds. Q: Can I use this seed on my whole lawn or just patches?A: Both. It’s perfect for spot repairs of bare patches, but you can also use it to overseed your entire lawn if it’s looking thin. For whole-lawn overseeding, use about half the rate you’d use for bare soil. Q: How often should I water after sowing?A: Keep the soil consistently moist but not waterlogged. Water lightly 2-3 times per day for 5-10 minutes during the first 2-3 weeks until the grass is established. Once grass reaches 5cm, reduce to deeper, less frequent watering. Q: When can I walk on the new grass?A: Avoid walking on newly seeded areas for at least 3-4 weeks. Once the grass is firmly rooted and about 5-7cm tall, light foot traffic is fine. Wait 6-8 weeks for normal use. Q: When should I first mow the new grass?A: Wait until the grass reaches 7-10cm (around 3-4 inches) tall before the first cut. Set your mower to its highest setting and only remove the top third of the blade. Never scalp new grass. Q: Will birds eat all my seed?A: Some seed loss to birds is normal, but it shouldn’t significantly affect results if you’ve sown at the correct rate. For small patches, you can cover with garden fleece or fine netting until germination occurs. Q: Can I apply fertiliser at the same time as seeding?A: Yes, a starter fertiliser or pre-seed feed high in phosphorus will help root development. Avoid high-nitrogen feeds which can burn tender seedlings. Wait 4-6 weeks after germination before applying standard lawn feed. Q: What if it rains heavily after I’ve sown?A: Light rain is beneficial, but heavy downpours can wash seed away or cause waterlogging. If heavy rain is forecast, delay sowing or cover seeded areas with fleece. If seed has washed into clumps, gently redistribute once the soil drains. Q: Why hasn’t my seed germinated after 2 weeks?A: Check soil temperature (needs to be 8°C ), moisture levels, and seed-to-soil contact. Seeds need to touch soil to germinate, if sitting on thatch or debris, they won’t take. Rake lightly and ensure consistent watering. ��️ 30-DAY GUARANTEE What if it doesn’t work?
