Frog Grass

Frog grass, scientifically known as Axonopus compressus, is one of the most popular residential lawn grasses in Metro Manila and across the Philippines. It's also commonly referred to as broadleaf carpet grass because of its wide, flat leaf blades that grow close together to form a dense, carpet-like mat on the ground.

So why do Filipinos call it "frog grass"? The name comes from the fact that frogs love to hide in its soft, thick cover. The dense growth creates a cool, moist microenvironment near the soil surface — the perfect spot for small frogs, especially during the rainy season. If you've ever walked across a lush frog grass lawn after a rain shower, you've probably seen a few tiny frogs hopping around.

What makes frog grass stand out from other lawn grasses is its exceptionally soft texture. The wide leaf blades feel smooth and comfortable underfoot, making it the top choice for homeowners who want a lawn where their family can walk barefoot, where kids can play safely, and where pets can run around without rough or scratchy grass bothering them.

Frog grass has excellent shade tolerance — probably its biggest advantage over other common Philippine lawn grasses. It performs significantly better in areas under trees, beside walls, and in courtyards that receive only partial sunlight throughout the day. If your yard has large trees or structures that cast shade over portions of the lawn, frog grass will fill in and stay green where carabao grass and other varieties would thin out or turn patchy.

This grass spreads through stolons (horizontal runners along the soil surface), which means it naturally fills in gaps and bare spots over time. Once established, it forms a thick cover that suppresses weeds by blocking sunlight from reaching the soil. It grows well in the Philippine tropical climate with moderate water needs — consistent watering helps it thrive, but it's not as drought-hardy as carabao grass.

In terms of maintenance, frog grass falls in the medium-maintenance range. It needs mowing every 2 to 3 weeks to keep it looking neat and carpet-like. During the wet season, you may need to mow more frequently as it grows faster with abundant rainfall. Keep the mowing height at 3 to 5 centimeters for the best appearance.

Frog grass is the preferred choice for Filipino homeowners who want a soft, lush lawn without the premium price of blue grass. It delivers that manicured, carpet-like look at a more accessible price point, and its shade tolerance means it works for a wider variety of yard conditions than most other lawn grasses available locally.

Installing frog grass is straightforward and doesn't require professional landscaping skills. Here's a step-by-step guide to help you get a beautiful, soft lawn:

Step 1: Prepare the Ground

Clear the area of weeds, rocks, old grass, and debris. Use a rake or hoe to loosen the top 2 to 3 inches of soil. If the existing soil is compacted clay or sandy, add a layer of garden soil or loam (about 1 to 2 inches) on top to improve the growing medium. Frog grass prefers slightly moist, well-draining soil — avoid areas where water pools after rain.

Step 2: Level the Surface

Use a flat rake or a wooden plank to level the soil surface. A smooth, even surface ensures the grass patches make good contact with the soil and prevents low spots where water can collect. Fill in any dips or holes before laying the grass.

Step 3: Moisten the Soil

Before laying the grass, water the prepared soil thoroughly so it's evenly moist but not muddy. Frog grass establishes faster in slightly moist conditions — this step is especially important and gives frog grass an advantage in shaded areas where the soil stays cooler and retains moisture longer.

Step 4: Lay the Grass Patches

Place the frog grass patches tightly next to each other with no gaps between them. Press each patch down firmly so the roots make contact with the soil underneath. For sloped areas, you can use small wooden stakes or bamboo pins to hold the patches in place until they root.

Step 5: Water Generously

After installation, water the entire area thoroughly. For the first 2 weeks, water your new frog grass lawn at least twice a day — once in the early morning and once in the late afternoon. Frog grass needs extra moisture during establishment compared to tougher grasses like carabao. Keep the soil consistently moist but avoid flooding.

Step 6: Let It Establish

Avoid walking on the newly installed grass for at least 2 to 3 weeks. Within 4 to 8 weeks, the frog grass should root fully and begin spreading via stolons to fill in any small seams between patches. In shaded areas, frog grass tends to establish even faster than in full-sun spots because the cooler, moister conditions suit it well.
