As the name already impressively expresses, the lean or dry grassland prefers nutrient-poor soils. This can usually be a sandy bottom, which in addition can not store the water for very long. Thus, the growth in this lawn is very low, which in turn favors many wildflowers.
Usually there is the same seed to buy with wildflower seeds. Of course, the growth could be accelerated by fertilizing, but this results in frequent mowing. As a result, slow-growing wildflowers can not develop. Therefore, the addition of fertilizer should be largely dispensed with.
Soil for lean grassland preparation
- Before you can start sowing, all plants should be removed. Then the floor has to be loosened.
- Even trees should be cut back so that they can not affect the growth of the lawn by leaves and too much shade.
- In many cases it is recommended to plant potatoes before planting a skinny grass. Especially if the soil still has too many nutrients, this is a good way to extract the nutrients.
- After the potatoes are harvested, sand should still be mixed under the ground. For nutrient-poor grasslands, it is important that only very few nutrients are present in the soil.
- The best way to do this is to use a moulder so that the sand and topsoil can mix better.
- Whether the soil now meets the requirements for a dry meadow, is evident in the color. Because by the addition of sand or gravel this goes clearly into the light.
- Once the soil has a very light color, it is finally ready for sowing. Even if growth slows down, wildflowers can develop better.
- After the sand has been incorporated towards the end of the summer or fall, the grass mixture can be sown.
Only when the soil hardly shows any nutrients, this is just right for the nutrient-poor grass. Above all, however, the plants that are contained in the seed mixtures are important. These are all winter proof and can survive frost without damage. These are usually wildflowers, such as Kartäuser- or Heidenelke or small rattle pot and eyebright. The last two species grow on the roots of the lawn and keep growth under control. Thus, it must be mowed less, which is very good not only for the gardener, but also for the plants. The less mowed the better the plants and small animal world. Because these natural plants like to attract bees, who then have something to do diligently. But other microorganisms like to stay in this nutrient-poor grassland, which in turn is good for the birds.
Slow growth also in the flowers
Since the flowers are perennial plants, one or two varieties should be below that already bloom in the first year. Because all other flowers including the lawn need time to develop. If the autumn is relatively mild, it can happen that the first plantlets look curiously out of the ground. But usually you have to wait until spring to do something on the bare ground. Also, the nutrient-poor grassland does not need to be further protected during a long and hard winter, as it endures both strong cold and hot summers. Then it's pretty fast, because in the spring, everything is green, even if it is not clear what is currently growing. If the warmer temperature continues, the first plants will slowly blossom. One of these early plants is the cornflower, which develops its splendor in the first year.
Mow only once or twice a year
In order for the wildflower meadow to develop optimally, it should not be mowed more than twice a year. Also, some plants need more than a year to finally flower. Therefore, annual plants are a good solution, otherwise the grasslands would be quite bare, so just green. The addition of fertilizer should be avoided as this only accelerates growth. Here is the time for the lawn and the flowers, but the biodiversity especially on insects and thus on birds makes up for it again. For a nutrient-poor grassland is a natural grass that has also grown in fields in the past. Unfortunately, this bothers with today's agriculture or is simply fertilized with the same. Exactly that does not need such a lawn however. Although the preliminary work is very labor-intensive, but this lawn is rewarded afterwards with its colorful splendor and this requires very little care. A small biotope for areas in the garden that would otherwise be fallow.
Create lean grass - a checklist
Before the actual work can be started, a checklist should be made. Then up are the steps of the preliminary work. These are as follows:
- free the soil from all plants
- If necessary, plant potatoes before conversion to remove excess nutrients
- If the soil is too dark, sand or gravel with a tiller
- then remove footprints with a roller
- deploy finished seed mixture
- after that, the nutrient-poor grass no longer needs care
Worth knowing: What is a nutrient-poor grass?
- A nutrient-poor grass does not appear lush green like many meadows, but is brownish and slightly stunted.
- A nutrient-poor grassland is a special biotope that forms in nutrient-poor locations.
- A characteristic feature of a nutrient-poor grassland is the species composition of cabbage and half-shrub plants.
Worth knowing: Natural vs. artificial grasslands
Often today you will find a naturally occurring grasslands on skid slopes, because in the course of time arise here again and again new areas that are populated by herbs and flowers. Even on abandoned land, such as old military training areas, still grasslands can be found today. Here, after the breaking up of concrete floors, many different herbs and grasses have accumulated due to the weather, so that such a biotope could arise. However, these natural nutrient-poor grasslands are becoming increasingly rare, as the eradication of large grazing animals and the suppression of nature by man mean that seeds can no longer spread so well. Already in the Neolithic times, grasslands were created by human hands, usually near settlements.
Today, a grassland is often created in the garden instead of a paved garden path. Even on courtyards, the use is always appealing. The creation of a lean lawn is actually quite simple, because it must be sown only a plant mixture for nutrient-poor grass, which can be obtained from specialist dealers.
Worth knowing: sand vs. Lime neglected grassland
- Sandy dry grass is characterized by low-growth plants that cope well with humus and nutrient-poor sandy soils.
- Also characteristic here are the low storage capacity of water, the very low nutrient content of the soil and the extreme temperature rise.
- A sand-dry grassland can be found above all in landscapes that are characterized by their own time and therefore have hardly any forest cover.
- Lime grasslands can be found on southern slopes, which have good drainage. Thus, the low precipitation can be dissipated quickly. Ideal for a lime-poor grassland are shallow limestone soils.
- The typical plantation of such a grassy lawn consists of sparse, short grasses and a variety of weak-growing flowers, such as the Pasque or the silver thistle.
- In Central Europe, the limestone-nutrient-poor grassland is the species-rich plant society.
