What is Holcus?

Holcus is a genus consisting of eight kinds of grass. These grass, often called soft grass, come from Asia, Africa and Europe, although they also grow on some of the Atlantic Ocean islands. Plants are a source of food for some types of moths and butterflies in the order of adhesive. Although most species are not invasive, at least one is a problem when it escapes grown soil. That's why it's his common American name of velvet grass. It produces a good pasture of grass because it can prosper under different conditions, even if it can kill heavy frost and tramping. The plant is considered an invasive species or weeds in several countries, including the United States. It is able to disrupt ecosystems by killing the species of native plants. Yorkshire fog prefers soil that is not rich in nutrients and has poor drainage. Therefore, reduce some of the grass population by increasing phosphorus and potassium or drying of the soil.

in 2006 CaliforniaE classified the impact of Holcus Lanatus as mild. Alternative methods for controlling this invasive grass have been investigated since 2010. The species has been reproduced rapidly as a result of numerous factors. Yorkshire fog produces many seeds that fall at the least movement. Disrupted soil, such as soil rooted by animals such as wild pigs, helps the plant in reproduction. People are guilty of spreading invasive species by mowing grass down and then using the same equipment to cut elsewhere without its first cleaning.

Another species, Holcus Mollis , is also called creeping soft grass or creeping velvet grass, is at the beginning of the summer from Western Asia and Europe and flowers. This species has a soft, gloomy appearance like Holcus lanatus , and it is the average height of grass. It prefers very shady areas, but it is known that it is successful even after all shadows are removed. This species is considered to be weed in England, although variants that are sterile and sometimes fistThey are in the gardens.

Third species, Holcus Setiger or annual fog, is originally from South Africa and flowers in the spring. It is an annual grass that is usually a shadow of white or green, even if it can have a gray shade. This species can identify this species from the Yorkshire fog plant according to its distinct glut. Since 2010, it has been considered this species naturalized in several countries due to reported observations outside his native station.
