Should You Offer Weed Spraying as a Service?

If you’re already mowing lawns, it’s only a matter of time before a customer asks, “Hey, can you spray those weeds too?”

And on the surface, it seems like a no-brainer. You’re already on-site so why not try offering weed spraying as a service. You’ve got the time. It’s easy money, right?

Well… yes and no.

Let’s break it down properly, because while it can be a good service to offer, there are some traps you need to know about.

The Easy Stuff – Path and Driveway Sprays

If the customer just wants a quick zap of weeds along a concrete path or driveway, it’s usually a straightforward job.

A few squirts of glyphosate, and it’s done.

We normally eyeball it and quote on the spot — maybe $2 to $3 a minute, or bundle it in with the mowing if it’s light.

You don’t need to overthink it. A hand sprayer, some weedkiller, and you’re good to go.

The important bit here is: you’re not touching the lawn. There’s very little risk. The weeds are easy to identify, and overspray won’t kill the garden or the grass.

This is the type of job where weed spraying makes sense as a simple add-on.

The Hidden Dangers of Spraying Lawns

Here’s where things get sticky when offering weed spraying as a service.

As soon as a customer asks you to spray on the lawn itself, you’re in different territory.

It’s easy to mess this up. Some sprays that are “safe for lawns” only work on certain grass types. Others need very specific mixing ratios, or they’ll burn the lawn.

Even spraying at the wrong time of day or in the wrong weather can turn a decent lawn into a brown mess within days.

And guess what? When that happens — you’re the one holding the bag.

Lawn spraying isn’t like mowing. A mistake doesn’t grow back in a week.

Real-World Story – The Kindergarten Lawn Disaster

A while back, I was mowing a property for a local kindergarten.

They’d had the same older guy doing the lawns and gardens for years. Friendly bloke. Knew his stuff. Everyone liked him.

One day, they asked him to spray some weeds in the lawn. He agreed — he had done it many times before.

Well, it turned out badly. He sprayed the wrong stuff, or maybe the mix was off, and the entire lawn turned yellow, then brown, then dead.

A kindergarten with no lawn is a problem.

He thought he was covered by insurance. But when he called them up, they told him flat out: you’re not insured for this — because spraying chemicals requires proper certification, and he didn’t have it.

No licence, no cover. And a very big problem.

The Legal Side – Know What You’re Allowed to Do

This is where a lot of guys get caught out.

You might know how to spray. You might have sprayed for years with no issue.

But that doesn’t matter much if things go wrong and you’re suddenly on the hook.

In many places, especially if you’re charging for the work, there are rules around spraying herbicides and pesticides. You may need a licence or specific training, especially if you’re applying chemicals to lawns, gardens, or anywhere children or pets might be.

And when it comes to insurance, this is where the fine print matters.

Most general business policies won’t cover chemical damage unless you can prove you were authorised and competent to do the job.

No paperwork? No pay-out.

Even if you’re doing everything right, one wind gust, one spill, one wrong product — and you could be looking at thousands in damage. So it’s not just about knowing how to spray… it’s about being covered when something doesn’t go to plan.

Another Example – “Kut and Kill Lawn Care”

If you think it’s just a rare thing — it’s not.

There was a lawn company (real name: Kut and Kill) that made headlines after they killed off dozens of lawns.

Same story: spraying gone wrong. Big financial loss. And, again, turns out they weren’t properly covered.

They ended up having to shut down that side of their business completely. Public backlash, insurance headaches, legal threats — the lot.

These stories aren’t rare. They’re just not often talked about until someone’s lawns are dead and someone else’s reputation is in tatters.

The Takeaway – Know Your Limits When Offering Weed Spraying as a Service.

Here’s the short version:

• Weed spraying is a great service — if you stick to the jobs you’re allowed and trained to do.
• Don’t wing it. Especially with lawns.
• Don’t assume your insurance covers it. Most policies don’t unless you’re qualified.

If you want to offer lawn weed spraying, look into local rules and training. Get certified. Make sure your insurance is up to scratch.

And if a customer asks for something that feels a bit outside your comfort zone — it’s okay to say, “Sorry, I don’t offer that.”

It might feel like you’re walking away from easy money, but in reality, you’re avoiding a massive headache.

Wrapping Up

Spraying paths and driveways? Easy upsell.

Spraying lawns without the right paperwork? Easy lawsuit.

So keep it simple. Do what you’re legally allowed to do, and do it well. If you want to expand, do it properly — get trained, get certified, and protect yourself before taking on the risk.

Trust me: it only takes one mistake to learn this the hard way.
