What about the yellowing of cinnabar root leaves? the causes and solutions of cinnabar root leaf sagging

Friends who love flowers and plants have heard of cinnabar root, but many friends do not know how to raise cinnabar root. What should we do if the leaves of cinnabar root turn yellow? Cinnabar root is evergreen all the year round. When we cultivate cinnabar root in our lives, the leaves will droop. So what is the cause of this phenomenon, and how can we solve it?

What if the cinnabar root leaves turn yellow?

1. Because the frequency of watering is too high; if the cinnabar root leaves turn yellow due to watering, it is necessary to loosen the soil in time and stop watering until the surface of the soil is slightly whitened before watering. As long as the soil is moist, it cannot be watered. It should be watered thoroughly after the topsoil is dry, like the light, and do not put it in a position without light.

2, due to the low temperature, cinnabar root has been frozen, now do not put it under the condition of too high temperature, between 10 and 15 ℃, after 10 to 15 days and then gradually rise or maintain the status quo, when the outdoor temperature is suitable, it is better to maintain in the open air.

3. If the yellowing is caused by insect pests, it is necessary to spray insecticides to kill insects.

Causes of leaf sagging of cinnabar root and its solution

First, the reasons for the sagging leaves of cinnabar root

1. Bacterial wilt: the main manifestation of bacterial wilt is that the plants on the ground are not abnormal, but they suddenly lose their vitality during the day, the aboveground parts wither and the stems and leaves remain green. This process is relatively rapid, first of all, the root lesions rot, and then gradually invade upward.

2. Drought: because cinnabar root is not resistant to drought, if it is not watered enough to make it too dry for a long time, it will lead to the phenomenon of leaf dry scorch. Of course, this not only refers to not watering for a long time, but also easily leads to the lack of water in the roots of cinnabar root and the drooping leaves of cinnabar root.

II. Solutions

1. Bacterial wilt is easy to occur in the case of high temperature and humidity and the soil is not changed for a long time, hardening or watering is more inclined to apply nitrogen fertilizer, so we should first make preparations from the growth environment to avoid these adverse conditions mentioned above. If bacterial wilt occurs, it needs to be controlled by spraying wet streptomycin in time.

2. If cinnabar root is caused by dry coke sagging of leaves due to drought, watering must be sufficient and reasonable. Pay attention to keep the soil moist but not stagnant, watering must be thoroughly watered.

Planting techniques of cinnabar root

1. Humidity management

Like the humid or semi-dry climate environment, the air phase humidity of the growth environment is required to be 50-70%, the lower leaves yellowing and falling off when the air relative humidity is too low, and the upper leaves are not glossy.

Temperature management: because it is native to the subtropics, it has strict requirements for winter temperature and stops growing when the ambient temperature is below 8 ℃.

2. Lighting management

The ability to adapt to light is strong. Put in indoor maintenance, as far as possible in places with bright light, such as well-lit living room, bedroom, study and other places. After indoor maintenance for a period of time (about a month), it should be moved to an outdoor place with shade (heat preservation in winter) for a period of time (about a month), so alternately.

3. Fertilizer and water management

①, for potted plants, in addition to adding organic fertilizer when potting, proper fertilizer and water management should be carried out in the usual maintenance process.

②, spring, summer and autumn: these three seasons are its peak growing season. Fertilizer and water management circulates in the order of "Huabao"-- clear water-- "Huabao"-- clear water, with an interval of about 1-4 days.

③ Winter: during the dormant period in winter, the main task is to control fertilizer and water. Fertilizer and water management circulates in the order of "Huabao"-clear water-clear water-"Huabao"-clear water-clear water, with an interval of about 3-7 days.

④ for ground-planted plants, according to drought conditions in spring and summer, fertilizer and water were applied for 4 times: first, a small trench was opened at 30cm to 100cm outside the root neck (the larger the plant, the farther away from the root neck), the width and depth of the ditch were both 20cm. The ditch is sprinkled with 25-50 jin of organic fertilizer, or 1-5 two-grain compound fertilizer (chemical fertilizer), and then poured with water. After the beginning of winter, before the beginning of spring, fertilize again according to the above method, but do not need watering.

Growth environment of cinnabar root

Cinnabar root likes warm, moist, shaded and ventilated environment, and the growth temperature is 8: 32 ℃. The suitable temperature for its growth is 16 ~ 30 ℃. When the natural temperature is higher than 32 ℃, the growth is stagnant. Shading, ventilation and humidification (air relative humidity 70% ~ 80%) should be strengthened to cool down. Anti-freezing measures should be taken when the winter temperature is below 3 ℃. Not resistant to drought and exposure, poor growth in full sunlight, and not suitable for wet environment. The requirement of soil is not strict, but it grows well on acid or slightly acidic sandy loam or loam soil with loose and moist soil, good drainage and rich humus.

Cinnabar root has a wide variety of fruits, bright red and beautiful, which is very beautiful and has great ornamental value. The above content hope that in your breeding process, can help you solve the problem.
