Choosing a grass type and sowing seeds is just the beginning of painstaking lawn care. For each seed to germinate and young sprouts to turn into a luxurious lawn, you need to know how to water them properly. Lack of liquid can permanently kill the grass as it dries out. An excess of it will also negatively affect the lawn health, as it will lead to the decay of the vegetation. From my own experience, I have deduced several basic rules and steps for watering new grass seed. Read them in the article below.

Irrigation is necessary for the lawn throughout the entire growth process; however, the first steps are the most important for its health. It is essential to correctly prepare the soil and maintain soil moisture by properly watering a new lawn. I will tell you more about all this.

Watering a New Lawn from Seed

How often to water new grass seed is a pretty challenging question. There are no universal recommendations regarding the timing and volume of liquid. To avoid overwatering, you should take into account the soil structure, the local climate, and, of course, the grass kind. Some types of lawns can easily withstand mild drought, while others are very sensitive to sudden changes in humidity. Only by studying these aspects will you develop an optimal new grass watering schedule.

Why is keeping grass seed moist essential? Like any other plant, lawn grass seeds need water to grow and develop. Proper irrigation at the initial stage will allow seeds to “wake up” at the right time. The liquid makes outer shells softer, allowing natural light and nutrients to penetrate inside and start the growth process. When seeds are sufficiently nourished, sprouts break through their shells and come to the surface, and roots go deep into the soil.

Essential Tips on Watering a New Lawn

As I said, every lawn requires personal care. You can determine the exact amount of liquid and the optimal days for watering. However, there are a few basic steps that every gardener should follow.

Step 1: Preparation

Sowing the territory should be accompanied by high-quality preparation. You should carefully inspect the area for weeds, fungi, and mold; if necessary, use means to destroy them. Next, it’s vital to ensure the soil is adequately aerated and has a balanced pH. For several days before planting, you need to moisten the soil so that water penetrates an average of 6-8 inches. To determine the depth, stick a regular screwdriver into the ground. If it sinks pretty easily, the soil is sufficiently moist. The last watering should be carried out no later than one day before sowing.

Step 2: Seeding and first watering

Spread seeds evenly throughout your yard; try to avoid overseeding. Right after planting, the ground should be moistened, and watering should last for 10-15 minutes. The best way to water new grass seed is to use a pre-installed sprinkler system. Keep in mind that the pressure should not be too intense so as not to wash off seeds that have not yet taken root. Use the method above again and check the soil moisture with the screwdriver. The tool should freely enter the ground to a depth of about 4 inches.

How quickly does grass seed dry out? It is enough in the first days not to moisten the soil well for the plants to die. That is why, for the viability of your lawn, care, before the first shoots appear, is critical.

Step 3: Further care

It is important to ensure the ground doesn’t dry out. When to water new grass seed? I recommend doing it in the morning and evening, once or twice, depending on weather conditions. The liquid will have time to soak into the soil and will not stagnate on the surface, as it can be with night processing. Now it is important to moisten the ground to a depth of two inches.

As soon as the first green shoots appear on the surface, watering grass seedlings should be reduced to once a day. It should take you an average of 15-20 minutes. When the grass is tall enough to mow, move on to the recommended irrigation schedule for your area.

Can you over water grass seed? My unequivocal answer is no. You should never allow it to happen, as it will lead to seed death, mold growth, and the appearance of lawn diseases and pests. Fixing such a mistake will be tricky.
