Do you wonder, “How long does the grass seeds have to grow”? Perhaps you have been sowing, and watering continuously, and you do not see any grass seed growth. Well, the problem may not be something you are doing wrong. Sometimes, the problem is about what you are not doing correctly; you just need to give your lawn some time to grow.
So how long does the grass take to grow? Ideally, most grass will grow within 10 days after planting and will be fully developed in 6-8 weeks. When fully established in the 6-8 week mark, you are free to walk and play as much as you see fit! However, a lush, green and established lawn requires patience and attention to achieve it.
Factors to Consider When Planting Grass
Certain things must be taken into account when planting grass and expecting the best result. These are the environment in which the seed is trying to grow, e.g. climate and soil conditions, including the method of planting, the type of grass seed you are sowing, the mixture of grass and subsequent care.
- Climate and soil conditions
Sunlight, temperature, and water are the main elements that drive the growth rate of your lawn; however, even with these elements, the grass can still be detrimental to poor soil preparation and adverse weather conditions that delay or completely impede their ability to germinate. Therefore, the climatic conditions and the condition of the soil in which the seed was sown are crucial for its germination and, secondly, it’s rapid growth
Most grass species will grow at temperatures in the region of 8-10 degrees more, but if these temperatures are not consistent and fall frequently, germination and establishment may take longer. For best results, sow your grass seeds when temperatures reach 8-10 degrees more, steadily, for at least two weeks. In the United Kingdom, this generally means that the planting season is from March to September, always attentive to frost, snow or flooding. When deciding when to plant, see a two-week forecast.
- Ideal soil/planting conditions
The seedbed should be free of weeds and moss, leveled and without drainage. If it flops on any of these fronts, the seed may have difficulty growing. Similarly, if the seed is sown incorrectly, buried too deep (unable to reach sunlight), too close to the surface or planted at an incorrect speed, etc., it may also have difficulty germinating.
- The type of grass seed
Some grass species germinate at different temperatures, and this also amounts to how long it will take the grass seed to grow completely. For example, perennial ryegrass is a cold season lawn and only requires temperatures of 8-10 degrees consistently to germinate. This makes its growth extremely fast, especially in the United Kingdom, since it is easy to achieve 8-10 degrees consistently during the planting season (spring, summer, early fall).

- Grass Seed Mixture
Grass seed mixtures are often a mixture of multiple species. Most of these blends contain a mix of ryegrass and perennial fescue, except some specialized combinations for sports, shaded areas, and mixtures that are 100% perennial ryegrass or 100% fescue. What is in your mix will determine how fast it will grow. As indicated above, the perennial ryegrass grows more quickly than the fescue, so if you want a very fine ornamental grass (100% fescue), be prepared to have to wait a little longer for everything to happen.
- Subsequent care
Then, after you have planted your grass in excellent climatic conditions in a perfect seedbed with a perfect seed and the ideal mixture for what you need: how can you be guaranteed more rapid growth? Well, your lawn needs water. After seeding your grass, you should water it at least once a day and deeply during the first weeks.
NOTE: Avoid watering when it rains, and you will soon see that the small green sprout begins to appear throughout the lawn.
How to Grow Grass Fast?
Here is my guide on how to successfully grow grass.
Prepare the Soil
- As you aim at the problem areas first, prepare the soil properly.
- Use a scoop and garden rake to scratch the ground 1 to 2 inches above the surface, then dig to remove roots and rocks.
- Add planting soil to the top of your existing land and smoothen using the rake.
- Add the starter bud fertilizer over the soil using a spreader, if you are not using sowing soil.
- Mix well-decomposed manure in the ground, filling the holes.
- Smooth the area with a rake and then apply it gently.
Sow Grass Seed
- Now it's time to plant seeds.
- A spreader is necessary for the uniform growth of the new bud. In large areas, you can use a drop spreader for coverage. In smaller spaces, you may need a hand spreader.
- Use a rake to cover the seeds with soil.
- Cover the area with a small layer of wheat straw to hold the seeds in place and help them retain moisture.
Tamp the Seed
- Fill your lawn roller with sand or water to add weight, then go over to the area's top to tamp the seed down. This will keep the birdies away from eating the seeds and will help control erosion.
- If you live on a hill, you may choose to use a seed mat to keep the seed from washing away.
Water the Lawn
- A well-watered lawn is crucial for growing grass.
- Wet the soil 4 to 6 inches deep immediately after planting. For new seeds, a soft approach is vital. Use a sprayer with a fog setting to avoid washing the soil and seeds.
- Subject to weather conditions, follow up with daily watering or twice a day until the seeds are well established.
- It is essential never to let the seed dry, as this hinders germination. The seed takes a minimum of seven to 14 days to grow and much longer for warm-season lawns (up to 30 days for grasses such as Zoysia and Bermuda).
- Until the seedlings are visible, water lightly with a sprayer daily until the lawn is approximately half an inch high.
- Once you can mow the lawn, water at the rate of 1 inch per week to keep the bases healthy, it is more important to water deeply and less frequently than to water every day. It will help grow the roots and help the grass to survive in drought conditions.
Grow Your Grass Organically
- Growing grass without having to rely on chemicals becomes much easier when you start with seed that wouldn’t have to fight the conditions it will be grown in.
- Do not cut the grass excessively. Do not cut more than one-third of the height of a leaf when mowing and allow the height of the grass to remain 3 inches. Mowing the short grasses stresses the plant and can deplete the soil of moisture and minerals.
- Do not overwater the lawn.
- Organic fertilizer comes in several forms and can usually begin with many of the same tools as chemical fertilizers.
- Avoid weed control chemicals and rely on organic herbicides and more natural methods.
How Often Do You Water New Grass Seed?
Before planting new grass seeds, it is essential to start with watering. Nature designed the seeds to respond to moisture, so it makes perfect sense that watering the grass seeds properly is essential to start the germination process that results in healthy growth.
- Several days before sowing your new seed, water the area to a depth of 6 to 8 inches.
- Water the new grass seed for 5 to 10 minutes immediately after planting to soak in the first few inches of the soil tenderly.
NOTE: How often to water new grass seed depends on the amount of rainfall your region will get after seeding. If you’re not getting any rainfall, you’ll need to water new grass seed twice per day until the first couple inches of soil is moist.
Best Time to Water New Grass Seed
The best time to water grass seeds is in the morning and the afternoon. These are the calmest parts of the day, which allows water to be absorbed into the soil instead of vaporizing. A water timer can ease the process of when to water lawn seeds, so you can quickly and efficiently irrigate your newly sown lawn without problems.
