What is a Lawn Refresh, and how does it help a lawn recover?
When a lawn starts to struggle, thinning out, feeling spongy underfoot or letting moss back in sooner than it should, the cause is usually at the surface. Over time, thatch and moss build up at the base of the grass. The better grasses weaken and coarser ones take their place. After a dry summer, the damage can be more obvious still, with patches where the grass has gone altogether.
A Lawn Refresh is our planned approach to putting that right. It combines scarification, overseeding across the whole lawn and a soil improver, so the lawn recovers evenly and grows back stronger. It isn’t a quick fix or a cosmetic treatment. It works with the lawn’s natural growth cycle, which is why timing and method matter as much as the work itself.
Not every lawn needs it. When we do recommend it, this guide explains why each part matters, how we help new grass establish and what to expect in the weeks afterwards.
Why scarification comes first
A little thatch protects a lawn. Too much of it blocks water, air and nutrients from reaching the roots. It also holds rain at the surface, which is one reason some lawns stay brown long after dry weather has broken.
Scarification lifts that layer out. It can look quite severe on the day, and that’s normal. The material we remove is bagged ready for your green waste bin.
Removing thatch creates space, but space alone isn’t enough. Left bare, it’s exactly where moss and weeds settle.
Why aeration can matter too
On our clay soils, compaction is very often part of the problem. When soil is packed tight, water runs across the surface instead of soaking in, and roots struggle to go deeper.
Hollow tine aeration lifts out small cores of soil, letting air and water back in and giving roots room to grow. It can be added to either Lawn Refresh option on the same visit. You can read more on our aeration page.
Why overseeding follows straight after
Overseeding straight after scarification means new grass fills the open ground evenly, and the thinning you see afterwards is temporary rather than prolonged. In simple terms, overseeding is what turns scarification into a recovery process rather than a risk.
We overseed the whole lawn, not just the visible bare patches. Focusing only on patches tends to give uneven results. Seeding across the whole surface introduces stronger grasses throughout, evens out colour and texture and helps the lawn cope better with drought, wear, disease and moss. The lawn improves as a whole rather than in isolated areas.
The role of the soil improver
Our natural soil improver helps the new seed germinate and improves the structure of your soil over time. It’s particularly well suited to our local clay and heavy soils.
With repeated applications, it helps drainage. That encourages grass to root more deeply, which in turn leads to a healthier lawn.
Two ways to sow the seed
With a standard Lawn Refresh, the seed is spread across the surface after scarification. It works well and is what we’d normally recommend. The seed does have to find its own way into the soil, though, which is why birds take some of it and why so much depends on keeping it damp.
Lawn Refresh Precision uses our direct drill seeder. After scarifying, the machine cuts narrow slots into the soil, places the seed at the right depth and firms it in. The seed sits in moist soil, out of reach of the birds, and more of it germinates. It’s the option we’d recommend if you’re concerned about seeding and watering.
The drill is a heavy, bulky machine, so it can’t reach every lawn. We’ll always confirm access when we visit.
When is the best time?
Early autumn is the ideal window. The soil is still warm from summer, and there’s usually enough natural moisture to keep new seed going.
Spring works well too, but it brings different challenges. The soil warms slowly, particularly on clay, and dry spells in April and May are common. We usually seed from late March or April, once the soil has warmed.
Where spring work follows a dry summer, the winter months still matter. Rain rewets the soil, and seasonal treatments keep moss and weeds out of the bare patches, so the renovation starts from cleaner ground.
Watering new seed
New seed needs to stay damp until it establishes, so the first few weeks are the most important. Hand watering usually isn’t enough. A hose with a sprinkler on a timer works far better. We’ll leave you a watering and aftercare guide so you know exactly what to do and when.
If you’d rather let nature take its course, the seed will still germinate once conditions are right. It will be slower, but it’s still effective.
How Water Solution helps
After a dry spell, soil can become water repellent, so rain and watering run off or sit on the surface instead of soaking in. Water Solution®, our wetting agent, helps water move evenly into the soil and stay where the roots can use it.
For new seed, that means watering goes further, dry patches are less likely and germination is more even across the lawn. It’s particularly helpful for busy households and metered water users. It stays in the soil for around four months, ready to work whenever moisture arrives.
How fleece helps in spring
If you choose a standard Lawn Refresh in spring, we recommend our Spring Germination Fleece. It’s a lightweight horticultural fleece laid over the seeded lawn.
The fleece holds warmth at the soil surface and protects against late frost. It reduces moisture lost to wind and sun, stops seed washing or blowing away and keeps birds off. Germination is quicker and more even at the time of year when conditions are least predictable.
Fleece is always temporary. We’ll let you know when it’s ready to come off, once the new grass is up, so light and air can reach the lawn.
What to expect afterwards
For the first week or two, the lawn will look thinner than before. That’s the thatch gone, and it’s a good sign.
Seed can take up to four weeks to sprout. It’s quicker when the soil is warm and kept damp, and slower in a cold spell or without watering. Early growth often looks thin or patchy, and that’s perfectly normal. On a drilled lawn, the new grass comes up in neat rows at first, which soon knit together.
Once the new grass reaches 3 to 5cm, it’s ready for its first mow. Take no more than a third off, as regular mowing helps it thicken. Avoid heavy use for the first six to eight weeks while the roots grow strong.
Like any renovation, things may look worse before they look better. With the right care in those first few weeks, the results are well worth the wait.
A measured, planned approach
A Lawn Refresh isn’t about chasing perfection. It’s about doing the right things at the right time, so the lawn becomes thicker, healthier and more resilient without needing to be replaced.
