After a summer of heat and drought, lawns take a battering, and the same questions start arriving at the office. Is it dead? Will it come back? Do I really need all this work doing? They’re fair questions, every one, and you deserve honest answers rather than a sales pitch. So here are the ones we’re asked most, answered plainly.
Is a wetting agent worth it, or is it just watering by another name?
It’s a fair question, because “wetting agent” is a term that tells you nothing. Here’s the plain version.
When soil dries out for a long spell, something happens that surprises people: it starts to repel water. The ground goes hard, and rain runs straight off the surface or sits in puddles instead of soaking in. You can water for twenty minutes and find the soil an inch down is still bone dry.
A wetting agent fixes exactly that. It breaks the surface tension so water, from rain, dew or a hose, actually sinks in and spreads evenly down to the roots where it’s needed. It doesn’t add any water itself. It makes the water you already get work far harder.
For most of our customers that means one very practical thing: the lawn recovers on less water, so there’s far less standing about with a hose. It keeps working for two to three months, and because more water reaches the roots and less runs off, it’s better for the lawn and for the drains. On a lawn that’s been through a hot, dry summer, it’s often the difference between a lawn that limps back and one that properly recovers.
Is it safe for children and pets?
Yes. Once the treatment has been applied and watered in, the lawn is perfectly safe for children and pets to use as normal. As with any lawn treatment, we’d simply ask everyone to stay off while the technician is working and until it’s settled, and your technician will let you know if there’s anything specific for the day.
Scarification
I had it done once by another company and the lawn looked awful afterwards.
Because that’s actually the treatment working, and it’s the bit that gets misjudged. Scarification helps remove the dead thatch strangling your lawn, and for a week or two afterwards the lawn looks thinner while it does. Done at the right time, in autumn, with feeding and that were we always recommend new seed to follow, the lawn comes back thicker than before. Done at the wrong time with no recovery plan, it just looks bare. The treatment isn’t the problem. The timing and the aftercare are everything, and that’s the part we plan around.
I’ve got an electric lawn rake. Doesn’t that do the same job?
It helps, and we’d always encourage a light rake through the season. But a home rake works the surface. A proper scarifier cuts down into the base of the sward and lifts out the deeper thatch a rake can’t reach. Think of it as the difference between light brushing and a proper deep clean, both useful, but they’re not doing the same job.
I had it done a couple of years ago. Why again?
Because thatch is always rebuilding, quietly, every year. It’s not a one-off fix, it’s maintenance, like clearing gutters. Leave it too long and it builds back to the point where water and feed can’t get through, which is often what’s behind a lawn that struggles in dry weather.
Seeding
Why seed the whole lawn? Surely you just do the bare patches?
You can patch, and sometimes that’s all that’s needed. But overseeding the whole lawn does something patching can’t. It thickens tired, thinning grass everywhere, not just where it’s worn through, and it works fresh, hard-wearing grass varieties into the whole sward. A thick lawn also leaves no room for moss and weeds to move in. Patch-only tends to leave you with a lawn of mismatched ages and colours, and the thin areas you didn’t quite catch become next year’s problem.
The birds just eat the seed though, don’t they?
Some, always, and it’s a fair worry, nobody wants to pay for seed that ends up feeding the local pigeons. But the numbers are well on your side. A single handful of our professional lawn seed holds tens of thousands of seeds, far more than the pigeons could ever make a dent in, and we seed at a rate that allows for them taking their share. Direct drilling helps too, because seed in contact with the soil is much harder to reach than seed scattered on top. And that’s exactly why we back autumn seeding with our germination guarantee. If an area doesn’t come through as it should, we come back and apply more at no extra cost. The pigeons get a snack, your lawn still gets its grass.
What is direct drill?
Rather than scattering seed on the surface, a well tested and proven technique when the preparation has been done well, a direct drill places the seed into little slots in the soil, at the right depth, in good contact with the ground. Better contact means better germination, and seed tucked into the soil is far harder for birds, especially those pesky pigeons, to reach. It’s simply a more reliable way to get seed to take.
Aeration
Do you clear up the cores afterwards, and why leave them at all?
Hollow tine aeration pulls small plugs, the cores, out of the lawn and leaves them on the surface. We break these down with the scarifier to return soil and beneficial organisms to the surface, which does the lawn good.
Why do I need aeration at all?
Because compacted soil is the hidden cause behind a lot of lawn problems. When soil is squeezed hard, by summer drought, by foot traffic, by children playing, there’s no air space for roots and no route for water to get down. Aeration opens the soil back up so it can breathe and drink. After a hard, dry summer it’s one of the most useful things you can do for a lawn.
Do you put a top dressing or topsoil down as part of the work?
Usually not, and it’s worth explaining why, because a lot of people expect it. Spreading topsoil over an established lawn sounds helpful, but a thick layer smothers the grass that’s already there, and cheap bagged topsoil often brings in weed seed of its own. So as a rule it does more harm than good on a lawn we’re trying to thicken.
What actually helps a tired lawn is getting good contact between seed and the soil that’s already there, which is exactly what scarification and direct drilling do. On a lawn recovering from drought, opening the soil and improving it from below with aeration does far more than adding a layer on top.
There are times a light dressing has its place, levelling out dips and hollows. When that’s the right call for your lawn, we’ll suggest it. But it’s a considered step for a particular problem, not something every lawn needs, and we’d never spread it just for the sake of it.
A word for family lawns
If your lawn doubles as a football pitch, a paddling pool spot and a general racetrack, you’ll know it takes a beating. That’s not something to feel bad about. A lawn that’s genuinely used is doing its job, and it’s exactly why we do what we do.
But heavy use compacts the soil and wears the grass thin, and a dry summer on top of that leaves a lawn really needing help. This is where autumn renovation earns its place. Relieving the compaction, clearing the old thatch and thickening the grass with hard-wearing seed doesn’t just repair this year’s wear, it builds a tougher lawn that stands up to next summer better. A well-renovated lawn recovers from a football match a good deal faster than a tired, compacted one.
Still not sure what your lawn needs?
That’s what we’re here for. Ask your technician on the next visit, or get in touch, and we’ll give you an honest view. If your lawn doesn’t need the full works, we’ll tell you.
