Grass Grows Sideways – Your Ultimate Guide To A Thicker, Denser Lawn

ByRimon Chowdhury Updated on

Have you ever looked at your lawn and felt a bit defeated? You water it, you feed it, you mow it, but it still has those frustratingly thin, patchy areas that just won’t fill in. It’s a common story I hear from fellow gardeners, and it can make you feel like a lush, carpet-like lawn is just a dream.

I promise you, it’s not a dream, and the solution is simpler than you think. The secret isn’t just about growing up; it’s about encouraging your lawn to grow out. When you learn how to make grass grows sideways, you unlock your lawn’s natural ability to repair itself, creating a thick, resilient, and beautiful turf.

In this complete guide, we’re going to walk through this process together, step by step. We’ll uncover the science behind sideways growth, explore the incredible benefits, and I’ll share my best practices and pro tips to get your lawn spreading. Let’s get started!

Understanding the Magic: Why Does Grass Grow Sideways?

It sounds a bit strange at first, doesn’t it? We think of grass as growing vertically. But the healthiest lawns have mastered the art of horizontal expansion. This all happens thanks to the way different grass plants are designed to spread and colonize new ground.

It all starts at the crown of the grass plant, which is the tough, whitish area at the base, right at soil level. This is the control center for growth. From the crown, grasses can send out specialized stems designed for spreading.

There are three main ways your grass accomplishes this amazing feat:

  • Tillers: Think of these as new grass shoots that emerge from the original plant’s crown, right alongside the parent shoot. This is how a single grass plant becomes a thicker clump. Almost all grasses produce tillers, but some do it more aggressively than others.
  • Stolons: These are above-ground runners that creep along the surface of the soil. At various points along the stolon, new roots and leaf shoots (new plants!) will form and tack down. Grasses like St. Augustine and Bermuda are famous for their powerful stolons.
  • Rhizomes: These are the stealthy cousins of stolons. They are below-ground runners that spread horizontally underneath the soil surface. They send up new shoots to the surface as they travel, filling in bare spots from below. Kentucky Bluegrass is the star player when it comes to rhizomes.

By understanding these growth habits, we can create the perfect conditions to encourage them. It’s less about forcing the grass to do something unnatural and more about giving it exactly what it needs to do what it does best.

The Lush Rewards: Unpacking the Benefits of Grass Grows Sideways

So, why should you put in the effort to promote this lateral growth? The rewards go far beyond just looks. When you master these techniques, you’re building a healthier, more resilient lawn ecosystem from the ground up. This is one of the most important aspects of our grass grows sideways guide.

Here are some of the fantastic benefits of grass grows sideways:

  • A Thicker, Denser Turf: This is the most visible benefit! Sideways growth is nature’s way of filling in bare patches. A dense lawn feels wonderfully soft underfoot and creates that sought-after “green carpet” look.
  • Natural Weed Suppression: Weeds are opportunistic—they thrive in bare, thin areas where they don’t have to compete for sunlight, water, and nutrients. A thick, dense lawn literally chokes out weeds by leaving no room for them to get started.
  • Increased Durability and Self-Repair: A lawn with a strong network of stolons and rhizomes is incredibly resilient. It can better withstand foot traffic from kids and pets and will quickly repair itself from minor damage or stress.
  • Improved Soil Health: The interconnected web of roots and rhizomes helps to stabilize the soil, preventing erosion. It also improves the soil’s structure, allowing for better water absorption and reducing runoff.
  • Enhanced Drought Resistance: A dense turf shades the soil, keeping it cooler and reducing water evaporation. This means your lawn can stay greener for longer during dry spells, making it a key part of any sustainable grass grows sideways strategy.

Your Step-by-Step Guide: How to Make Grass Grow Sideways

Alright, let’s get our hands dirty! Encouraging your grass to spread is all about creating the right environment through smart, consistent care. Don’t worry—these aren’t complicated chores. They’re simple adjustments to your routine that make a world of difference.

1. Master Your Mowing Technique

This is the most critical step, and it might be the opposite of what you think. To make grass grow sideways, you need to mow high, mow sharp, and mow often.

When you cut off the top of a grass blade, the plant’s growth hormones are redirected from vertical growth to developing roots, tillers, and runners. Mowing higher (around 3-4 inches for most cool-season grasses) leaves more surface area on the blade for photosynthesis, which fuels this sideways expansion. Stick to the “one-third rule”: never remove more than one-third of the grass blade in a single mowing. This often means mowing more frequently during peak growing seasons, but it’s the single best thing you can do.

2. Water Deeply, Not Daily

Shallow, frequent watering encourages a shallow, weak root system. To support a sprawling network of rhizomes and stolons, you need to water deeply and infrequently. This trains the roots to grow deeper in search of moisture, creating a strong foundation for the plant.

Aim to provide about one inch of water per week, delivered in one or two sessions. Use a rain gauge or a simple tuna can to measure how long it takes your sprinkler to put down an inch of water. The best time to water is early in the morning to minimize evaporation.

3. Fertilize for Healthy Spreading

Think of fertilizer as the fuel for this growth engine. A well-fed lawn has the energy to send out tillers, stolons, and rhizomes. A balanced, slow-release nitrogen fertilizer is your best friend here. Nitrogen (the “N” in N-P-K) promotes lush, green leaf growth, which in turn fuels the whole plant.

Follow a feeding schedule appropriate for your grass type and region. Generally, feeding in the early spring and again in the fall provides the key nutrients needed for vigorous growth.

4. Aerate to Give Roots Room to Breathe

Over time, soil can become compacted from foot traffic, rain, and mowing. This compaction squeezes the air and water channels out of the soil, making it incredibly difficult for rhizomes to spread and for roots to grow. This is one of the most common common problems with grass grows sideways.

Core aeration is the solution. This process involves pulling small plugs of soil out of the lawn, relieving compaction and allowing air, water, and nutrients to penetrate deep into the root zone. For most lawns, aerating once a year in the fall is perfect.

Choosing Your Champion: Best Grass Types for Sideways Growth

While the techniques above will help any lawn, your success will be supercharged if you have a grass type that is naturally inclined to spread. If you’re seeding a new lawn or overseeding, choosing the right variety is key.

Grasses with Strong Spreading Habits (Stolons & Rhizomes)

  • Kentucky Bluegrass (KBG): The king of rhizomes. KBG is renowned for its ability to aggressively spread and form a dense, self-repairing turf. It’s a top choice for cool-season lawns.
  • Bermuda Grass: A warm-season champion that spreads vigorously via both stolons and rhizomes. It’s incredibly tough and drought-tolerant, perfect for sunny, high-traffic areas.
  • Zoysia Grass: Another warm-season spreader that uses both stolons and rhizomes to form an exceptionally thick, dense carpet of grass.
  • St. Augustine Grass: This warm-season grass spreads with powerful, fast-growing stolons, making it great for quickly filling in areas in shady, warm climates.

Grasses with Limited Spreading Habits (Bunch-Forming)

Some grasses, known as “bunch-type” or “clump-forming” grasses, primarily grow by producing tillers to make their existing clump thicker. They don’t send out runners. These include:

  • Tall Fescue
  • Perennial Ryegrass

These are still fantastic grasses, known for their durability and disease resistance! Just know that to fill in bare spots in a fescue or ryegrass lawn, you will likely need to rely more on overseeding than on natural spreading.

Sustainable Grass Grows Sideways: Eco-Friendly Best Practices

A beautiful lawn doesn’t have to come at the expense of the environment. In fact, the healthiest lawns are often the most eco-friendly. Incorporating eco-friendly grass grows sideways practices into your routine is easy and effective.

  • Grasscycling: Don’t bag your clippings! When you mow, leave the clippings on the lawn. They break down quickly, returning valuable nitrogen and organic matter to the soil. It’s free, natural fertilizer.
  • Organic Fertilizers: Choose slow-release organic fertilizers like compost, worm castings, or milorganite. These feed the soil microbes, building a healthy soil structure that supports robust root and rhizome growth.

    • –Smart Watering: Water only when the lawn needs it. Look for signs like a bluish-gray tint or footprints that remain visible long after you’ve walked on the grass. This conserves water and encourages deeper root growth.

  • Compost Topdressing: Once a year, after aerating, spread a thin layer (about 1/4 inch) of high-quality compost over your lawn. This is one of the best grass grows sideways tips for improving soil life and structure.

Frequently Asked Questions About Sideways Grass Growth

How long does it take to see my grass grow sideways?

Patience is a gardener’s best virtue! You won’t see changes overnight. With consistent high mowing, deep watering, and proper feeding, you should start to notice a visible increase in density and the filling in of small bare spots within 4-6 weeks during the active growing season.

Will this sideways growth damage my sidewalks or garden beds?

For aggressive spreaders like Bermuda or St. Augustine, stolons can sometimes creep into unwanted areas. This is easily managed with a string trimmer or a spade edger. Regular edging during your mowing routine will keep a clean, crisp line and prevent any encroachment.

Can I make clump-forming grass like Tall Fescue spread with runners?

Unfortunately, you can’t change a grass plant’s fundamental genetics. Tall Fescue will never produce stolons or rhizomes. However, by following the best practices in this guide, you can encourage it to produce more tillers, which will make each individual clump much thicker and denser, helping to crowd out weeds.

Is it better to overseed or encourage sideways growth for bare patches?

It depends on the size of the patch and your grass type. For small, fist-sized bare spots in a spreading-type lawn, encouraging sideways growth is often enough. For larger patches (dinner plate-sized or bigger) or for any bare spots in a bunch-type lawn, overseeding is the faster and more effective solution.

Your Journey to a Lush Lawn Starts Now

See? The idea that grass grows sideways isn’t some complicated horticultural secret—it’s about working with nature, not against it. By making a few simple tweaks to your lawn care routine, you are empowering your grass to build the thick, resilient, and beautiful lawn you’ve always wanted.

Remember the keys: mow high, water deep, feed right, and give the roots room to breathe. You’re not just maintaining a lawn anymore; you’re cultivating a living, breathing ecosystem.

So go on, give these tips a try. I know you’ll be amazed at the results. Happy gardening!
