The perfect lawn in three steps
Spring is the best season to plant new lawns. The necessary preparations can be started in April if there is no more snow. When laying out the lawn, it usually decides how the grass will grow in the future.
Especially at the end of April/beginning of May the conditions for the first sowing are ideal. During these months, not only are the temperatures very mild, but also the soil is already warming up, which favours the germination of the grass seeds. But the preparations for the perfect lawn can already be started at the beginning of April.
Preparation of the soil
Ideally, the topsoil, which usually originates from excavation, should be evenly distributed as early as autumn. As a result, the topsoil had time to settle all winter long, so that the loose chunks of soil could again form a whole. In spring – ideally in March or early April – the planned lawn area should be turned over with a spade.
At this point, it is recommended that the entire soil be torn flat with a so-called cultivator. So the soil can be loosened in a gentle way and the natural layering is not disturbed. If the soil is too heavy, too loamy or too clayey, it can become permeable to water again with the help of sand or peat, which is mixed under the soil.
This process plays an important role for the perfect lawn, because rainwater should be able to start up in any case, as otherwise waterlogging will occur. If the soils are very sandy so that they dry out quickly, it is advisable to mix in peat or compost, as this can improve the soil structure. Some soils are also acidic. If this is the case, add lime before sowing. If you are not sure whether the soil is acidic or not, you can take a sample and have it tested.
If the pH value is below 5.5, then garden fertilizer lime should be mixed in. Now level the soil evenly using a rake. The soil should also be given a few weeks to regenerate. Before the planned sowing date, which should ideally be taken into account from April to June, the soil is cultivated with a mechanical garden tiller, so that an optimal and fine-grained structure can be created in the seedbed. The surface is then levelled again with a rake. The inequalities can be compensated relatively easily with the help of a wooden slat.
Sowing the seed
The seeding period is from April to mid-June in the spring, and from mid-August to mid-October in the autumn. The hot and dry time in high summer should be avoided. The optimum grass mixture should be chosen according to the requirements and purpose of use. Before sowing it is recommended to fertilize the soil a little bit. Depending on the type of lawn, there are also different fertilization options, often special fertilizers are offered for sale.
The spreader is suitable for uniform seed distribution. This can also be borrowed at a DIY store for a small rent. Care should be taken to ensure that the seed is evenly distributed, as this is the only way for the lawn to grow evenly. Sowing should be carried out on a windless day, so that the wind does not blow all seeds off the area immediately.
After the seed has been distributed, one of the most important steps is taken. The seeds should remain in the soil so that they can germinate. For this purpose, either a rake or a star wheel roller can be used.
This can also be borrowed from the DIY store for a small surcharge. Afterwards, the surface is smoothed with the aid of a roller or with running boards. This step should be carried out carefully so that the soil does not become too compacted. If the soil becomes too dense, irrigation cannot seep sufficiently into the soil and the scattered seeds are washed away.
The first lawn care
Uniform moisture is extremely important, especially in the first three weeks after sowing. As soon as germination has begun, make sure that the soil does not dry out any more. In order to prevent the young plants from being washed away, care should be taken during irrigation to ensure that only fine drops are added to the soil. The first cut can be made when the stalks are about 7 to 10 centimetres high and the sky is covered.
When mowing, care should be taken to ensure that the cutting height is uniformly high. Regular grass cutting is essential for the perfect lawn. When mowing, never cut deeper than half of the current blade height, even if a mowing appointment could not be noticed in the meantime. Particularly in the summer at high temperatures, mowing should be less than usual. The cuttings should also always be removed from the lawn so that the grass is adequately ventilated. The cutting height should ideally be between 3.5 and 5 centimetres.
Fertilizing cannot be avoided so that the lawn can be kept healthy and strong. It is advisable to use a slow-release fertilizer about two or three times a year. These have the great advantage that the nitrogen is only released gradually to the blades of grass, which prevents the so-called shock growth. If fertilisation takes place during a dry season, the lawn should be watered beforehand. In addition, the instructions for use should be adhered to in order to avoid over-fertilisation or under-fertilisation.
Targeted irrigation is essential for the perfect lawn. The lawn should be watered before it is completely dry. The water should fall slowly and in fine drops onto the lawn. In order for the moisture to penetrate sufficiently into the soil, water should be irrigated thoroughly. Never water at noon, but only in the morning or evening.
