Sempervivum var.
My name is "Changshengcao", originally named Sempervium, meaning to grow forever.I come from the Eurasian continent, mainly distributed in the mountainous areas of European countries such as Spain, France, Italy, and the northern part of the Balkan Peninsula. My hometown is cold in winter and hot in summer, with a large temperature difference between winter and summer, and drastic changes in temperature (long and cold in winter, short and hot in summer). The precipitation is concentrated, with four distinct seasons, mainly concentrated in summer.I belong to the genus Sedum in the family Sedum. I am a succulent plant that grows on high mountains. In Europe in the 1st century AD, people discovered my existence on mountains at an altitude of 4000-5000 meters. Initially, people threw me as moss between the rocks on the roof and in the yard. With my tenacious vitality, I thrived and multiplied in their yard.It was not until the 20th century that I was valued and loved by cultivators, who planted me in their own gardens and became a popular ornamental plant, gradually expanding from Europe to various countries.Because my unique breeding method is that a large evergreen grass can easily produce more than N chicks, just like a hen always following a group of chicks, everyone in my hometown gave me a friendly name "Hen and Chickens".When it comes to my family, the most familiar ones are probably Guanyin Lotus, Purple Peony, Spider Silk Rolling Juan, and so on. However, we are a huge family, and you only know a few common members of the family.Some people may ask if the evergreen grass will not die, but its amazing reproductive speed always gives people the illusion of immortality, so it is called the evergreen grass. Imagine if the evergreen grass is truly immortal, it will definitely become the object of research for many scientists. Perhaps it has long been eaten and extinct by those who pursue immortality.Some species have summer dormancy habits.Sensitive to high temperatures, attention should be paid to air circulation during cultivation. In spring and autumn, the soil should be kept moist for a long time, but continuous waterlogging should not be allowed.Evergreen grass has a long dormant period and should be slightly shaded. Pay attention to ventilation and cooling, keep the soil in the pot moderately dry, and prevent plant decay caused by stuffiness and dampness.Summer is prone to decay, and the main growth period is in the cold and cool season. It is suitable for greenhouse cultivation and prefers sufficient sunlight. Ventilation and cooling should be done well in summer, and watering should be controlled to avoid dampness and stuffiness.If the area you are in is relatively hot and humid in summer, it is necessary to do a good job of ventilation and increase the proportion of soil particles. In areas with high temperature and humidity in summer, it is recommended to shade and minimize or cut off water.It's best not to get wet, because the leaves of evergreen grass are small and dense. After getting wet, rainwater can easily gather in the middle of the leaves. If the sun shines after rain, it will be fatal. After the sun shines, your evergreen grass will become crystal clear and dazzling!Finally, harvest an empty basin.Many people think of the densely packed scale insects when they hear the evergreen grass. Many people say that the evergreen grass is prone to scale insects, and when it comes to pests and diseases, the most common pest of the evergreen grass is scale insects, which are small white carnivorous insects. In fact, scale insects are not only found in the evergreen grass. Other types of succulent plants in the Sedum family can still erupt with scale insects, but because the leaves of the evergreen grass are small and dense, it is easy for scale insects to hide, which creates the illusion that the evergreen grass is home to scale insects.Many other plants will grow, such as vegetables, woody plants, and so on.Generally, scale insects have 1-3 generations per year, with a few having 4-5 generations. Before the nymphs transform into adults, there is often an intermediate period during which their appearance becomes dull and some even stop feeding. This period occurs before and after the annual awakening of insects, and at the end of May to early June.At this time, most nymphs have not hatched for long, their surface has not yet secreted wax, and their shells have not formed, making them easy to kill with medication.Spray once every 7 days for 2-3 consecutive times.The early winter season is the best time to exterminate insect eggs. Using 1000 times 40% speed to extinguish or spraying 40% pure chlorpyrifos at 2000 times the entire plant can basically ensure that scale insects do not explode significantly throughout the year.If we can seize these three opportunities and spray pesticides, it will be twice the result with half the effort. At the same time, we can also control scale insects by burying small white medicine and furan Dan.Everyone and different regions have their own different maintenance methods. The above is for reference only and should not be copied.However, my personal suggestion is to shade the grass appropriately during the process of breeding it, so that the grass will not turn into pig liver color or even pitch black.$12.86
