How Long Does It Take for Grass Seed to Grow?

It typically takes between ten and fourteen days for your grass seeds to germinate and start growing.

But this can vary widely, based on your location and other factors.

Here’s what affects how quickly your grass seeds will germinate, plus tips for successfully sowing your lawn.

Growth Rate of Popular Grass Types

Here’s how long it takes some of the most popular grass types to germinate:

Grass Type	Growth Rate
Bermuda grass	5-14 days
Zoysia	14-21 days
Kentucky bluegrass	14-30 days
Rye grass	5-10 days
Fine fescue	7-14 days
Buffalograss	14-30 days
St. Augustinegrass	10-30 days (rarely grown from seed)
Centipedegrass	14-28 days
Tall fescue	7-14 days

Factors Affecting Grass Seed Germination

When planting either cool-season or warm-season grass, everyone wants to know how long it’ll take to see growth.

Keep in mind these factors:

1. Plant Grass Type

The grass type you choose largely determines how quickly it will germinate and grow.

Cool-season grasses, such as Kentucky bluegrass and bentgrass, that grow in the spring and fall, germinate in approximately four weeks.

With the likes of rye grass, it’s closer to ten days, and with tall and fine fescue, they usually take a couple of weeks.

Other hardwearing seed mixes can germinate as early as four days after sowing.

2. Soil Moisture Conditions

Grass seeds will germinate quickly in balanced soil conditions, where the soil is neither too dry nor too wet.

Always water lightly at first to prevent seeds from washing away or puddles from forming.

3. Time of Year

If the air or soil is too cold, your grass seeds won’t germinate, so avoid sowing in the winter or during a chilly spring.

If you do, the delayed germination will cause the seeds to be blown away by the wind or eaten by birds.

Extremely high temperatures can also inhibit the growth of new grass seeds, as they can dry out the soil’s moisture.

The best time to sow grass seeds is in early autumn or mid-to-late spring.

Choosing the Right Seed Mix

If your grass seed is taking longer than expected to germinate, you may have to ask some of these questions:

• Was the seedbed adequately prepared?
• Is the soil the right temperature
• What kind of mix did you purchase? Is it high-quality or hardwearing?

Choosing the right seed mix is a core aspect of getting a lawn that suits your needs and your site.

General-Purpose Lawn

If you plan to have a general-purpose lawn, you can have a mix of hard-wearing grasses that can withstand steady foot traffic, especially from pets and kids.

You can blend red fescues with bentgrass (browntop), tall fescue, and perennial ryegrass.

Keep in mind this combination grows quickly and needs frequent mowing.

Luxury Lawn

You can include a mix of dense, slightly robust, fine-leaved grasses such as browntop, red fescue, and Chewing’s fescue for your fine or luxury lawn.

Unlike the grasses ideal for a general-purpose lawn, these grasses are slow-growing and can be mown at a low height to achieve a neat finish.

Shady Lawn

For lawns in shady areas of your garden, such as beside fences, hedges, or underneath trees, you can sow hard fescue, browntop, and red fescue.

These aren’t hard-wearing, but fine-leaved grasses.

You can also tailor your grass seed mix to meet other specific needs, such as ease of maintenance, quick germination, or drought tolerance.

How to Sow a Lawn

After selecting your preferred grass seed, the next step is to prepare the sowing site. Here’s how it’s done:

• Step 1: Eliminate all perennial weeds, such as bindweed and couch grass, well in advance.
• Step 2: Break up compacted soil by digging or tilling to a depth of up to eight inches
• Step 3: Add home-made compost to help hold soil moisture
• Step 4: After digging, leave the site for about five or six weeks to allow the organic material to settle into the soil
• Step 5: Rake the surface in different directions to level the surface of the soil and eliminate any clumps or rock chunks

After preparing the site, you’ll get to sowing the lawn properly:

• Step 1: Weigh out the correct quantity of seeds for your lawn size, using the appropriate seed to lawn ratio as indicated on the packet
• Step 2: Divide the seeds into two separate batches and sow each half over the area, first in parallel rows, then from side to side.
• Step 3: Rake the sown area lightly to ensure that the seeds are covered with soil
• Step 4: Water the area gently without dislodging the seeds

For new lawns, it’s essential to water the seedlings regularly if there is no rain forecast.

This is usually done through a couple of thorough sprays a day until the seedlings are well-established, then, you can move to a more specified watering schedule depending on the grass type.

Tips to Successfully Grow Grass Seeds

To successfully grow your grass seeds:

• Sow when the soil temperature is at least 46 degrees F
• Keep the soil from drying out
• Use high-quality seed mixes and stick to the use instructions as indicated on the packet.
• Don’t sow if it’s too windy, as it’ll blow your grass seeds over the place.
• Keep the soil moist, but avoid overwatering

Grow Healthy Plant Grasses in Your Lawn

Several factors, such as the type of grass seed, weather conditions, and soil moisture, determine how fast your lawn grass will germinate and grow.

While most grass plants typically germinate within two weeks, it’s important to follow the right steps to ensure that you have a healthy, beautiful turf in the end.
