Evergreen grass is a succulent alpine plant, which has a high demand for light and good cold tolerance. According to the data, some varieties can withstand the lowest temperature of MINUS 30 degrees, and can be exposed all year round in most areas of China. Although the perennial grass is resistant to low temperature, it doesn't mean that it can be thrown into the cold outdoor immediately after being kept in a warm room for a long time. Plants can't stand any drastic changes in the environment. Evergreen grass can also accept conditional high temperature, that is, dry and ventilated high temperature. The highest temperature in my shed has reached 48 degrees, except for a few varieties with thin leaves, most of them can be safe and sound.
First, the planting environment
The ideal environment for long grass is rainy and windy mountain areas, barren soil, strong ultraviolet rays and cool weather. For us, there is no way to imitate this environment, and there is no need to imitate it. The adaptability and tolerance of long grass to the environment exceed my expectations. The best way for meat lovers to raise grass is to raise it in the open air. European growers even throw the perennial grass directly on the roof and let it grow. If it cannot provide an open air environment, the state effect will be discounted.
Second, flowerpots and soil preparation
The long grass hardly picks the medium, and any soil can be used. Players only need to choose the matching method according to their own maintenance habits. There is a need for concrete analysis of specific problems. Sometimes grass fans ask me how to mix the soil. I can only say, "If the hands are cheap, the proportion of particles is large or even whole, and if the self-control is good, the proportion of peat is large." For the general fans, to grasp a little is the permeability of the soil and add some perlite appropriately. At present, my way of mixing soil is: 2 parts of peat or sawdust, 0 part of garden soil/kloc-0, 1 part of river sand, 1 part of vermiculite, and an appropriate amount of slow-release fertilizer. I add river sand to enhance the water permeability of the soil, because I supply a lot of water and work hard. Garden soil is more used as fertilizer. In the proportion of soil, there is also the difference between the north and the south. The north is dry, which increases the proportion of peat, while the south is wet, which increases the proportion of particles. Generally speaking, it should be mixed according to personal preference and environment, and no formula can be applied to all.
Regarding pots, some people like porcelain pots, some people like pottery pots, and some people use small black squares. I think, anything can be done without holes. The quality of plants is often under personal control, but some media and pots are difficult to use.
Third, watering and fertilization
The long grass needs more water than most other Sedum plants, especially in the growing season. In the dry north, it is best to keep the soil moist, as long as the leaves do not turn down and there is no need to cut off water. Whether the color of perennial grass is gorgeous or not is the result of the comprehensive action of climate, temperature and humidity, and it is not green when there is more water.
The demand for fertilizer by long grass is not great, and the general slow-release fertilizer can cope with it. In the spring and autumn growing season, it is also possible to simply spray thin foliar fertilizer several times. Less or no fertilization will not cause any bad results. If there is too much ammonia nitrogen, it will grow in vain or grow into a huge plant.

Fourth, the light
In the spring and autumn growing season, receiving full sunshine is a necessary condition for the evergreen grass to reach its most beautiful state. When it is hot in summer, the perennial grass is in a semi-dormant state. At this time, it needs proper shading, just cover it with an ordinary sunshade net. If there is no sunshade net, it can be placed in a place where the midday sun can't be direct.
Five, the long grass in summer
Many flower lovers turn pale at the smell of summer. It seems that summer is the most annoying thing. In fact, summer also has many benefits, such as seedling raising and leaf cutting in early summer, which grows very fast. In fact, it is not as difficult as expected for the perennial grass to spend the summer. The perennial grass, which is in a semi-dormant state at high temperature, will adjust its summer, which means that its color turns green to avoid excessive heat absorption. Man-made intervention to strengthen the grasp of summer is to shade, strengthen ventilation (it is best to have electric fans in a continuous sauna day), and to shelter from the rain when it rains continuously to avoid toxic days after the rain, then we will prepare for the summer of long grass.
First of all, it is to make the root system grow well to the maximum extent, and it is best to fill a pot. If it is a newly cut evergreen grass seedling, it needs more water to urge it.
Secondly, comb the places that are too dense and cut off the small heads that are stacked in order to have better ventilation. Flower friends in some coastal cities said that Xia Feng is very big there, and I think it is necessary to get rid of some small heads, because the ventilation of the macro environment does not mean that the micro environment is also ventilated.
Finally, control water. In the growing season, if the leaves of the perennial grass turn down due to heavy water, the frequency of watering should be gradually reduced, and it should be restored as much as possible before midsummer. Water can't be completely cut off in midsummer, because the long grass is semi-dormant, so it won't completely enter the dormant state. When the pot soil is dry, it should be watered. The best way to water is to soak the pot, but don't soak it. Only supply some water to the capillary root at the bottom. The taproot above has no water absorption capacity, and it will rot if soaked for a long time. If there are many things, it is better to ventilate after soaking in the basin, such as blowing a fan.
Six, the propagation of perennial grass
The main propagation mode of perennial grass is cutting by asexual seedlings. Sowing often can't get the complete traits of the female parent, unless only one variety is planted in the collection area, it will bloom at the same time, which is very easy to cross. Some varieties give birth to more babies in spring, and some varieties give birth to more babies in spring and autumn. The most important breeding season is spring, so it is necessary to ensure adequate water supply.
The succulents of the genus Eupatorium are very hardy. Even in Xinjiang, they can spend the winter in the open air, growing in spring, autumn and winter, but stopping growing in summer and entering dormancy. If you want your succulents to grow healthy and beautiful, you must pay attention to their growth period.
