Why do people install costly plastic lawns? This is a good question. And so is this one from a person on Quora.com, “Why would daycares install plastic turf?” Let’s take a look.

Easy maintenance

It’s easy to maintain plastic lawns. I imagine you just gently sweep them or hose them down. People are busy and maintaining natural grass is expensive. You need machines, time, gasoline or electricity, you have to deal with green waste and fertilizer purchases and it all requires effort. Probably weekly effort.

That’s why some people hire professionals like Proper Landscaping to keep their lawns beautiful; and some give up by making a costly plastic turf purchase.

Situations calling for plastic lawns

Chafer beetles

On the West Coast, our lawns are plagued by European chafer beetles. The larvae are in the lawns and animals come dig them up thereby destroying patches of lawn. Now, the cheapest fix for this is raking, top-dressing with soil and over-seeding. But it gets very old when you have to do this annually. All of a sudden, plastic turf starts to look attractive.

Animals dig up lawns looking for juicy European chafer beetle grubs.

Patios below grade

I’ve seen shady, below grade patio lawn patches that turned to nothing every winter. It was a constant fight to keep five narrow strips of lawn alive. So, the owners all opted for plastic turf because it eliminated the headaches with maintenance.

Dog damage

The first time I ran into a company installing plastic lawn was in White Rock. By the way, if you’re still considering plastic lawn after reading this blog post, then I can put you in contact with this installer. Now, back to White Rock.

The owners have a narrow lawn patch and a large dog. They also like to use their sunny patio. But the small patch of lawn was no match for their dog. The copious amounts of dog urine “burn” the lawn because it’s way too much fertilizer for the lawn to absorb.

You can spray the dog spots with water in theory but in practice people just kick the dog out and let it do its business.

So, in this case, plastic solved their problem.

This used to be a nasty dog-damaged patch.

Poor access

One case from England showed an enclosed backyard where the only mower access was through the house! That’s not a good situation. I guess you could use a line-trimmer but you would still have to go through the house and the result would be a nice looking lawn. Here plastic lawn made sense.

The only access here is through the house so the owner opted for plastic turf.

The case against plastic lawns

I don’t like anything artificial in nature. If I had a house, I would either go for some sort of green alternative or I would maintain the lawn without gasoline mowers. If I had to use a gas-powered mower, I would definitely use Aspen fuel instead of regular gasoline.

I would never let my kids attend kindergarten with plastic turf.

Why not plastic turf? This is the key question.

Heat

Plastic lawns heat up and may require summer watering. And summer watering may not be possible with summer watering restrictions. A few years ago my son played a soccer match in sunny White Rock and the plastic turf was so hot, his plastic cleats were super hot. And I don’t even mention the off-gassing that may be going on as the heat hits the plastic. Right now, heat absorption is the biggest problem with plastic lawns.

Science notes

Maria Ignatieva, writing in Science (October 12, 2018, vol. 362, issue 6411) states that, “…..substituting …with plastic lawns eliminates real nature from cities and arguably reduces overall sustainability given that they reduce habitats, decrease soil organisms, pollute runoff water, and may have yet unknown negative consequences for human health through plastic particles.”

When I mentioned the above quote in my answer to the Quora question, some people got mad. I’m not saying you can’t have your plastic lawn. If you have deep pockets, do it. It’s your lawn.

But, plastic lawns kill or severely diminish life in the soil because they limit water infiltration and cook the soil as they heat up. Also, not many organisms want to make plastic turf their home.

Conclusion

I totally agree with Ignatieva, plastic lawns are not the answer. Overall, plastic lawns heat up our cities and they remove real nature from them. I personally would never buy one.

But, there are some desperate cases where plastic eliminates maintenance headaches.

Somebody on Quora.com posed this question and it took me just seconds to decide what the biggest no-no in lawn care is. I hate lawn scalping so much, I call it the ultimate sin. Just remember that new workers have to gain experience and are likely to make mistakes. It’s not the end of the world but they must be aware of it. Careless mowing shouldn’t be tolerated.

Here’s what scalping is and why it’s a sin.

Scalping

Scalping happens when your mower slips off the edge of your lawn and the blades cut into it. This leaves a nasty brown spot in your lawn. New lawn care workers are warned not to get too close to the edges because line trimmers are coming along to take care of the danger zones.

Note that line edgers can also slip and scalp lawns so be careful. The machine is different but the effect is the same ugly brown lawn patches. Or worse, patches.

This is a line edger scalp. Always line trim at the same height as your lawn.

Why it’s a sin

So, what’s the big deal? If you scalp your lawn doesn’t the grass just regrow? Not so fast.

It’s ugly

First of all, the scalp looks ugly. This is especially serious close to high-profile lawn areas. And also in late fall just before the lawn cutting season ends. Obviously, late season scalps will not cover over and will remain ugly all winter.

I witnessed this once when a ride-on mower dude made several mistakes on the very last cut of the season. My then-boss drove by and freaked out. If the dude wasn’t a perfect ride-on mower drone, he would have been fired. Remember, lawns should look great all season. Don’t scalp them.

Meristems

Grass blades grow from meristems. These are growth points located roughly in the lower third of each grass blade. So, when you cut below this point, the grass doesn’t regrow. The ugly patch gets covered over eventually as neighbouring grass spreads out. That’s if you’re lucky.

Scalp first aid

Smart lawn care workers quickly throw grass clippings over the scalp to make it look green, not brown. They also use line edgers to even out the green grass around the scalp to make it blend in more. Then pray to God your foreman doesn’t discover the mistake. By next week you could potentially blame someone else.

I’m kidding, of course. Mistakes happen. Just mow better next time. Mastery takes time.

Conclusion

Don’t scalp your lawns. It’s the ultimate sin in lawn care.

Never run your mower through tree wells. It’s a bad habit. Just look at the wheel marks and the ugly brown scalp.
