What is the annual bluegrass?
annual bluegrass, scientifically named Poa Annua , is an annual plant belonging to Poaceae or grass, family. The word poa is Greek for feed, although this particular grass is not considered a particularly useful feed for livestock. Also known as the annual grass of meadows, ordinary meadow and walkgrass, grows up to a maximum height of about 1 foot (0.3 m). This low -growing grass occurs throughout the world, especially in places with a slight climate. Flowers of the annual bluegrass flower in yellow or light green throughout the year, except for heavy winters.
have both male and female organs, flowers can pollinate themselves, although grass also benefits from wind pollination. This grass has light up to dark green leaves and short leaves have a smooth texture, are dull on the tip and tend to knock. The annual bluegrass produces brown seeds that usually ripen during April until November.
Thirostina S is considered easy to grow because it can survive in fine rough soilDách, which are well drained but damp. Annual bluegrass can also grow in very acidic and nutritionally poor soils. It prefers sunny spots because it is not doing well in the shade. The plant can withstand cool temperatures up to 47 degrees Fahrenheit (about 8.3 degrees Celsius). It attracts caterpillars of many types of butterflies, of which they act as a source of food.
The natural habitats of the annual bluegrass include wastelands, sophisticated soil and pastures. This grass is also located on the lawns, where it acts as a lawn or a lawn on the grass. The patches of this grass may brown during the summer because it tends to disappear in very hot weather. It is promoted by seed and, in addition to being found on lawns, is also used for golf, which gives green.
In most cases, cultivation is not required because the readily seeds fall from the plant, resulting in a rapid speed of seed spread. Some regions of the connectedStates such as Nebraska, Illinois and Wyoming included this grass in the list of invasive weeds. In these areas of the world, it concerns the interest of controlling its spread rather than its encouragement. In addition to the rapid speed of seed spreads, the seeds also lie before germination, making it difficult to control and eradicate grass. Control is still possible using pre -emergence herbicides that prevent seed germination.
