It takes a lot of effort, money and time to seed one’s lawn with new grass. When you’re done with it, you tend to feel relaxed but you can’t afford to relax for long. That’s because there are many more responsibilities to be undertaken and tasks you need to follow up with. One of the most important things you need to do is water your new grass seed.
The big questions are – how often should you water it and how much water does it need? The answer to these queries isn’t always straightforward as it depends on a lot of factors such as seed type, climate, time of year and more.
Following a regular watering schedule is essential for developing lush green grass on your existing lawn. To water grass seed, you’ll need to be patient, but there’s no major expenditure required. It’s a rather straightforward procedure that takes only a few minutes each week. In this article, we will provide you with a detailed guide on how often you should water new grass seed. We’ll also offer some insights on the best time of day to water your lawn and how much water it needs:

How Often Should You Water New Grass Seeds?
Before casting out new grass seeds, it’s important to water them properly. Organic seeds respond very well to moisture. Therefore, watering grass seed properly paves the way for a smooth germination process which, in turn, ensures its healthy growth.
When it comes to the frequency of watering new grass seeds, here are a few things you need to remember:
- A few days before you plant the seed, water the area in a way that it covers a depth of 6-8 inches. If you are wondering how to measure the depth of water penetration, then you’ll be relieved to know that it’s relatively straightforward. You have to insert a long screwdriver inside the ground. If you find that the screwdriver is getting pushed 6-8 inches within the ground without any difficulty, then this is an indication that the ground offers adequate water saturation.
- When you’re ready to plant new grass seeds, make sure they’ve been watered for 5-10 minutes. This is done to ensure that the first few inches of soil have been adequately moistened. After this, you must take steps to maintain the moisture in the seeding area. Keep in mind one key fact here. If you allow the seeds to dry out, they will become soft and eventually die.
- One of the most crucial components to consider when determining how often you should water new seeds is the amount of rainfall a location receives at a specific time. You’ll need to water fresh grass seed twice daily if you reside in an area that seldom sees rain. When you notice a few inches of the soil at the top have become moist, you may start doing this task once daily.

Most Appropriate Time to Water New Grass Seed
Wondering what’s the best time to water new grass seeds? The most appropriate time to water them is early morning.
At night, or in the early morning hours, is a fantastic moment to do this. You should attempt to water new grass seeds in the early mornings and late afternoons. This will make it much easier for the water to sink into the ground, ensuring that there is less of a risk of it evaporating into the air.
Using a water timer to keep track of how long you water the new grass seeds is beneficial. You won’t be stressed about remembering when and how often to water the grass seeds if you use such a gadget.
The amount of grass seeds to be watered is primarily determined by the area being seeded. If you’re seeding a big piece of ground, it’s a good idea to use a rectangular simple lawn sprinkler. For limited areas, you can use a tiny spot cheap lawn sprinkler system instead.

Preventing Water Evaporation
Watering grass seed for the first time necessitates devising appropriate measures to protect it from evaporation. Straw mulch could be used to help prevent water from evaporating quickly over the newly seeded lawn.
From 10 a.m, there’s more of a risk of water evaporating rapidly because of the increase in temperature. It’s a good idea to avoid watering the seeds until the weather is cooler. When you water the seeds at the proper time, the water will flow into the soil without evaporating. This also helps to save water by keeping it from evaporating as quickly.
Duration of the Process
The amount of time you need to set aside to water new grass seeds is dependent on multiple factors including the condition of the soil and the kind of sprinkler setup you are choosing. Watering grass seeds for ten minutes per session will offer it sufficient water to ensure the top few inches of the soil remain moist.
Once your grass seed starts growing and looks healthy, you can water deeper and with less frequency. Doing this helps older grass roots to extend themselves further into the soil. When you water grass seedlings, try to remember to extend your morning watering sessions with time.
We advise you to water the plants between 6 am and 10 am as long as the weather is sufficiently cool. To balance it out, you could reduce the time you spend watering the seedlings in the evening. An established lawn needs close to 1 inch of water every week.

Growth of Grass Seed
The area you live in and the climatic conditions in that region play an important role in determining the amount of time it will take for the new grass seed to grow. If the weather in the area is not favourable for the growth of grass seeds, it will take longer for them to grow.
Another important factor that determines the growth speed is the type of grass you decide to plant. Making this important decision marks the beginning of the grass seed growing process. A new grass seed could take anywhere between 3-28 days to grow. Following the right processes is key to ensuring they grow well and on time.
Apart from being visually appealing, a vibrant lawn becomes a good place for the different members of a family to relax and engage in recreational facilities. A healthy lawn proves to be beneficial in several ways in the long run. When it comes to watering new grass seeds, following a well-drawn out water schedule is very important.

People Also Ask
Can I water new grass seed in the sun?
It is best to water new grass seed in the early morning or late afternoon when the sun is not as strong. Watering in direct sunlight can cause the water to evaporate before it has a chance to sink into the ground and hydrate the seeds.
Can I overwater new grass seed?
Overwatering new grass seed can be just as detrimental to the growth of your seeds as not watering them enough. Excess moisture in the soil can lead to fungal or bacterial disease, or mold and mildew, which can kill the seeds before they have a chance to grow. Water your new grass seed until it is moist but not saturated.
How soon after seeding do you water?
Most grass seed begins to germinate within six days of planting, so it is important you are watering at least once per day during this time. After your new lawn has started showing signs of life and good health, regular watering schedules may vary based on rainfall or other environmental conditions that may affect your lawn’s health.

How to water new grass seed without stepping on it?
Don’t mistake grass that is yet to be seeded for dead, dormant grass. The new lawn hasn’t grown yet; it’s simply dormant. Once you’ve finished seeding, make the area a no-traffic zone. If possible, water the area with a sprinkler rather than by hand to minimize foot traffic.
How to water new grass seed without a sprinkler?
If you don’t have a sprinkler, you can still water your new grass seed. Use a hose with a spray attachment to lightly mist the seeds. Be careful not to wash them away with too much water pressure. Water in the morning so the seeds have time to dry before nightfall.
Should I water new grass seed before frost?
No. It is best to wait until after the ground has thawed and the last frost has passed before watering new grass seed. Watering before the ground has thawed can cause the water to freeze, which can damage or kill the seeds.

How long do you keep new grass seed moist?
It is important to keep new grass seed moist for at least the first three to four weeks after planting. Once the grass has germinated and begun to grow, you can reduce watering to once or twice per week. Remember to always water deeply, rather than frequently, to encourage strong root growth.
What temperature kills grass seed?
It is important to keep new grass seed moist for at least the first three to four weeks after planting. Once the grass has germinated and begun to grow, you can reduce watering to once or twice per week. Remember to always water deeply, rather than frequently, to encourage strong root growth.
