How long does lawn need to germinate - after sowing to germination

Category (ies): garden maintenance, lawn

Many hobby gardeners sow their lawn and then wait for the blades of grass to sprout. But how long does it really take for a lawn to germinate? In order not to contain the growth spurt, it is also important not to mow the lawn too early. Otherwise, germination could be contained. However, when and how long it takes for the lawn to grow depends on a number of factors.

In brief - this is how the new lawn germinates faster

There are a few tips and tricks that will help the lawn grow faster. Accordingly, the lawn does not have to be left to its own devices, you can also take action and promote germination. The lawn germinates faster with the following tips:

  • It is best to lay out the lawn in early autumn
  • You should prepare the soil well
  • A soil activator should be used if necessary
  • Choose the right lawn mix
  • The new seeds should be kept moist
  • Germination can be accelerated by using a growth film

How long does lawn take to germinate and grow?

It takes between seven and 20 days for the first stalks to grow out of the earth after sowing. However, the growth of the lawn depends on the seeds used and environmental factors. These are light, water, air and soil conditions.

For example, the lawn takes longer to grow when it's cold outside. If, on the other hand, it is too warm for the lawn, the ground may want to dig in a bit. However, if the temperature is constant and the weather lasts for many days, then the grass seeds have a very good prerequisite for being able to sprout. But it can also happen that the lawn grows unevenly at first. This may be due to the fact that some parts of the lawn are in the shade.

What are the influencing factors in germination?

You don't need math to be able to garden. However, there are the above factors that have a huge impact on the outcome. We would like to introduce these to you in this article.

water

Water is the trigger for germination to begin. The seedling of the grass enlarges as it absorbs the water. Various enzymes are also released to start the germination process.

However, if the seedling does not receive water, it cannot use the nutrients to continue the process of germination. If the seedling does not get any water and thus dries, the germination process is interrupted. It is therefore important that the seedling is continuously supplied with water. It is not advisable to vigorously submerge the soil of the lawn every few days, as it dries out again in the meantime.

Continuous watering is therefore better. It is also advisable to roll the seedlings after sowing so that the seedlings can better absorb the moisture. Why? The seedling gets better contact with the soil through the rolling. This favors a better absorption of the moisture.

The respiration of the seedling

For a seedling, just as it is for a human, oxygen is vital. He gets this oxygen from the soil. Most grasses, however, do not have an excessive need for oxygen.

How long it takes lawns to germinate depends, among other things, on the supply of oxygen. There is a risk that the seedling will not get enough oxygen if the soil is too firm. In such a case, the soil should be aerated. Oxygen deficiency can also occur if the seedlings receive too much water in the form of excessive rainfall or as a result of far too much watering.

Necessary temperature for lawn germination

The soil should have a temperature of over 10 ° C in order to spread the grass seeds. However, it is not advisable to plant the seeds in the first few days of spring when the thermometer has risen above 10 ° C. In order to adapt to the outside temperature, the floor always needs a little longer.

For most types of grass, a temperature between 16 and 23 ° C is optimal. However, there is an upper limit to the temperature at which grass seeds are no longer comfortable. Most of the seedlings therefore die at a soil temperature of 45 ° C. The longer the seedlings are exposed to this extreme temperature, the higher the mortality rate.

How long does lawn take to germinate? The history

All of the facts listed have a great influence on the germination process of the grass seeds. But how strong is the development of a seed during this time?

The seedlings absorb the water in the first step. All other processes are set in motion by the water. This allows the seed to grow into a fully grown blade of grass.

The water also causes the seedling to swell. This allows the nutrients to be absorbed by the seed. The seed thus increases its surface area and it absorbs even more moisture.

As already mentioned, the absorption of moisture releases enzymes. These keep the entire germination process going. Among other things, the enzymes are responsible for enabling the seedling to gain energy.

The seed coat will burst when the seed has absorbed and converted the nutrients. The actual germination and growth process begins at this moment. At the same time, photosynthesis begins with the formation of the first cotyledon.

Help with growing the lawn

The number one priority on a freshly sown lawn is good watering. It is also helpful to loosen up the soil with the rake every now and then. This allows air to reach the seeds. You should also keep an eye out for weeds before they establish themselves in the lawn. Remove this immediately if you discover it. Weeds take away the area for the grass to grow and can disrupt the growth process.

If a seedling has grown for the first time, it is weak. The seedling is therefore unable to assert itself against weeds or other plants. While clover plants look beautiful, they are a threat to the lawn and can lead to bald spots.

Before the lawn is mowed for the first time, you should therefore also give the green stalks time to grow. The plants must first become powerful before they are cut. However, you shouldn't overdo it with mowing the lawn. It makes sense to give the lawn a little more time to grow. You can start mowing for the first time after the lawn has grown for a few weeks.

The germination time is different for lawn seeds

How long does lawn take to germinate? This question cannot be generalized. The different types of grass require different lengths of time for the phases of the germination process. The exact duration varies depending on the prevailing environmental conditions. The following table gives you an overview of the average germination time of the most important grass types:

Conclusion

How long does lawn take to germinate? That depends on many factors. First of all, this depends on the type of grass seed used. Furthermore, this depends on the weather, the soil and the watering. If the ideal conditions are in place, you will have a beautiful, even lawn that you will enjoy for a long time.
