A thick, lush lawn is simply a great sight and often forms the centrepiece of the garden. Here we tell you how to successfully sow a lawn and what to consider.
Sowing lawn seeds: When is the best time?
In order for the lawn seeds to germinate, some basic conditions should be right. The grass seeds need a sufficiently warm soil temperature, which should not fall below 10 degrees. The ideal temperature is between 15 and 25 degrees Celsius. Therefore, either spring or the beginning of autumn is recommended for sowing lawn seeds. So you can still get started in September to the beginning of October.
Before sowing, the soil must be prepared. Dig the soil to about the depth of a spade. In addition to a spade, a digging fork is also suitable for this. At the same time, remove larger stones and weeds. Ideally, one to two weeks should elapse between digging and sowing the lawn. If this is not possible, the area must be levelled more thoroughly at the end instead.
Levelling the area can be done either with a roller or with wooden boards that you step on evenly several times. The floor should be firm and smooth at the end.
In addition, fertilise the area about a week before sowing. This promotes rapid growth of the lawn. Organic fertiliser or fresh compost is best suited. A so-called soil activator can also be helpful. It improves soil life and soil structure in heavily depleted substrates. The addition of bentonite increases the water storage capacity of sandy soils.
The choice of lawn seed
First check the condition of your garden soil to be able to choose the right lawn seed. Even if the soil has been well loosened and fertilised beforehand, you should still adapt the lawn mixture to your soil conditions. Only a drought-resistant lawn is likely to thrive on sandy soils. The site conditions and future function of the lawn should also be considered. For example, a shade lawn mixture is suitable for shady and semi-shady areas, and a so-called hardwearing lawn for areas that will be subject to heavy use in the future.
Sowing the lawn: This is how you proceed
Choose a day for sowing when the soil is still moist from previous rain. Otherwise, you can of course water it yourself. You can sow large areas with a spreader or small areas by hand. The right amount of seed is crucial. Use the information on the seed packet as a guide. There you will read how many grams of seed are needed per square metre of area. First measure your lawn and weigh the amount of seed accordingly. Walk the entire area in strips – once lengthwise and once crosswise – and spread as evenly as possible.
It is best to start with one square metre of area and the corresponding amount to get a feel for how densely you should scatter the seeds.
The area is then worked with a rake in longitudinal and transverse lines. This way the seeds are well distributed and can be easily worked in. Afterwards, the area must be rolled again or trampled with boards and feet so that the lawn seed has sufficient contact with the ground to grow.
First of all, it is important that the area is not walked on too often after the lawn has been sown. In addition, the soil must remain sufficiently moist in the period after sowing. In the first 4 to 5 weeks, you should water daily for about 10 minutes – preferably with a sprinkler that provides gentle irrigation. If you are using a garden hose, it should not be set too high so as not to wash away the seeds.
Once the lawn is well established, regular mowing and sprinkling will help it stay thick. Annual fertilising has the advantage that weeds do not gain the upper hand in the long run. By the way, don’t worry if it doesn’t become an English lawn right away, because you can always reseed it!
