Before You Install a Lawn, Read This

September 29, 2026 · Gavin Mohrmann, Orange Path Landscaping


I'm not anti-lawn. I want to say that upfront, because people assume.


I've installed plenty of grass. I've got clients who love their turf and maintain it well and use it constantly — kids, dogs, barefoot evenings in the backyard. Grass has a place. But before I install it, I want the client to understand what they're signing up for. Because turf grass, especially in Southern California, is not a low-effort choice. It is a commitment — one that costs money, water, and time every single week for as long as you own the property.


Most people don't know that going in.




The Three I Get Asked About Most


**Tall fescue** is the default for a lot of homeowners in Orange County — it's what you see in the nurseries and what most lawn services know how to maintain. It handles foot traffic reasonably well, stays green year-round if you water it consistently, and tolerates partial shade better than most warm-season grasses.


What it doesn't tolerate is neglect or drought. Fescue in our climate needs water two to three times a week in summer — sometimes more on a hot, exposed site. It thins out in heat and recovers slowly. It's also not a perennial in the true sense: a fescue lawn typically needs overseeding every couple of years because the existing grass gradually dies out in patches and the bare spots don't fill back in on their own.


**St. Augustine** is a warm-season grass — thick, aggressive, dark green, and it looks lush when it's healthy. It spreads by stolons rather than seed, which means it fills in gaps on its own, which is a genuine advantage. It also handles heat and coastal humidity better than fescue.


The tradeoffs: it goes dormant and turns brown in winter, which some clients genuinely cannot accept. It's susceptible to chinch bugs, which can devastate a lawn quickly and are common in SoCal. And it requires regular dethatching — the thick mat of stolons builds up over time and if you don't remove it, the lawn starts to suffocate itself. That's not occasional maintenance. That's a recurring job.


**Bermuda** is what you see on golf courses and sports fields because it handles high traffic and recovers fast from damage. In a residential setting, it's the most aggressive of the three — it will find its way into your planting beds and hardscape joints and keep coming back no matter how many times you pull it. That lateral spread is useful on a sports field. In a home garden, it becomes a constant battle at every edge.


Bermuda also goes fully dormant in winter, leaving you with a brown lawn for months. And like St. Augustine, it needs regular scalping and dethatching to stay healthy.




What Turf Actually Costs


The install is just the beginning. Here's what ongoing lawn maintenance looks like for a typical residential lawn in Orange County:


**Water** — A 1,000 sq ft fescue lawn needs roughly 15–20 gallons per square foot per year in our climate. That's 15,000 to 20,000 gallons annually for a modest-sized lawn. In a drought year with restrictions, you may not be able to give it what it needs, and you'll watch it go brown or die.


**Mowing** — Weekly or every ten days during the growing season. You're doing it yourself or paying someone to do it. Over the life of a lawn, that cost adds up significantly.


**Fertilizing** — Turf grass needs regular feeding to stay green and dense. Most lawns benefit from four to six applications per year. Skipping fertilizer shows up quickly in color and thickness.


**Aeration and overseeding (fescue)** or **dethatching (St. Augustine, Bermuda)** — Once or twice a year. Non-negotiable if you want the lawn to stay healthy long-term.


**Pest and weed management** — Grubs, chinch bugs, crabgrass, spurge — these are ongoing issues with warm-season grasses especially. Pre-emergent herbicide applications in spring, spot treatment as needed.


None of these are extraordinary. They're just the baseline requirements of turf. The issue is that clients often price the install and forget to factor in ten or fifteen years of ongoing inputs.




When I Recommend It Anyway


If you have kids who play outside constantly, or a dog who needs a real surface to run on, or you simply love the feel of grass underfoot — I'm not here to talk you out of it. Grass does things no hardscape or groundcover can replicate.


What I'll ask before we proceed:


  • How much of the space actually gets used? A large lawn that only gets walked on occasionally is a poor use of water and maintenance budget.
  • What's your tolerance for winter dormancy? If you want year-round green, your options narrow.
  • Do you have irrigation already, or are we budgeting that in?
  • What does the rest of the landscape look like? Grass surrounded by loose mulch and planting beds is a maintenance problem — grass will invade both.

  • If the answers line up, I'll install it and help you set it up to succeed.




    What I Recommend Instead


    For most Orange County properties, I find that a well-designed hardscape with selective areas of artificial turf or a groundcover like UC Verde buffalo grass gives clients what they actually want — a soft, usable surface — at a fraction of the ongoing cost. Buffalo grass, in particular, is a native-adapted warm-season turf that survives on rainfall alone once established in our climate. It's not as lush as fescue, but it's honest. It doesn't pretend to be something this climate can't sustain.


    Decomposed granite, flagstone, and well-chosen groundcovers can cover a lot of ground with almost no water and no weekly maintenance once they're established.


    That's not a sales pitch. It's just an honest accounting of where the time and money goes. If you go in clear-eyed about what turf requires, you'll either decide it's worth it — or you'll find something better suited to your life.


    Either way, you won't be surprised three years in.
