Desert rose leaves yellow

In botany, desert rose, also known as Tianbao flower, belongs to succulent plants. It likes high temperature, dry and sunny environment, and is resistant to extreme heat and cold. It is named desert rose because its origin is close to desert and red as rose. Mineralogical desert rose is a kind of gypsum crystal, born in the desert, shaped like a blooming rose, magnificent and magical, the main ingredient is limestone, because of its special geographical conditions and rare production, is a kind of all-natural strange stone.

Desert rose is very popular and popular as a family potted plant, and its leaves are usually yellowed. Sum up the experience of most flower friends and share several possible situations of leaf yellowing:

L, bought soon, in the adaptation period, a small amount of yellow leaves are very normal and common.

2. The flowerpot is airtight and the root is small, so as to avoid the long-term dampness of the pot soil and cause root rot.

3. When the temperature is low, winter will be in a dormant period, that is, the leaves turn yellow and fall off, or even fall into poles.

4. It is relatively resistant to drought, and the amount of water should not be too much each time. If there is more water, it is easy to cause root rot and cause leaf yellow.

5, the sun is too shady, but also remember not to expose to the sun, the leaves are also easy to yellowing, and affect flowering.

6. poor ventilation and insufficient light will inevitably lead to yellow leaves, and in serious cases, the whole plant will rot and die.

7. If you apply too much fertilizer, you should apply an appropriate amount of fertilizer, not more. What about the yellowing of desert rose leaves? find out the cause of desert rose leaves yellowing.

Desert rose is named desert rose because its origin is close to desert, so its plant shape is similar to that of desert rose. Desert rose is a very popular breeding plant. The leaves of desert rose are often yellowed in the process of artificial breeding, so what about the yellowing of desert rose leaves?

Brief introduction of Desert Rose:

Desert rose (Latin name: Adenium obesum.), in fact, it is not a rose growing in desert areas, and it has no close relationship or resemblance to roses. Also known as Tian Baohua, Apocynaceae, which is a plant of Apocynaceae. Tianbao flower is a succulent plant, also known as succulent plant. Succulent shrubs or small trees, up to 4.5 m; trunk swollen. Leaves alternate, apical, Obovate to elliptic, 15cm long, entire, apex obtuse and mucronate, fleshy, subsessile. Like high temperature, dry and sunny environment, heat-resistant, not cold-resistant, named desert rose because its origin is close to desert and as red as rose; Kenya and Tanzania, which originated in Africa, are beautiful when they are in full bloom and are often cultivated and ornamental.

What if the desert rose leaves turn yellow:

One: have not yet adapted to the environment

Newly bought desert roses are in the adaptation period, and the phenomenon of a small amount of yellow leaves is very common, and it is normal to wait for it to adapt itself after a period of time.

Second: root rot

Plant roots need to breathe, keep the soil loose, the flowerpot is airtight, it is easy to cause root rot, once the root rot plants naturally can not absorb enough nutrients. The solution is to remove the rotten part and loosen the soil. If all the roots rot, it will be hopeless.

Three: too much watering

From the name of the desert rose, we can see that it is more drought-resistant and should not be watered too much each time, otherwise it is easy to cause rotten roots and yellowing leaves. Control watering after removing rotten roots.

Four: the temperature is too low

Desert roses will be dormant when the temperature is low in winter. the leaves turn yellow, dry and even lose leaves in order to reduce water evaporation and nutrient consumption. it is a mechanism of self-protection, so don't worry. If you want desert roses to come alive in winter, move into the greenhouse.

Five: lack of light

Desert rose is a sunny plant, sufficient light can ensure its normal growth. If you put it in the shade now, let it bask in the sun.

Six: poor ventilation

Poor ventilation will inevitably lead to yellow leaves of the plant, and in serious cases, the whole plant will rot and die. The solution is to take it to a "breeze", that is, to move to a well-ventilated location, such as balconies, windows, and so on.

Seven: excessive fertilization

On the one hand, excessive fertilization will make the soil impervious, on the other hand, the concentration of extracellular solution is too high, and the root cells lose water and die. The result is root rot until death. Therefore, fertilizers should be in the right amount, and remember not to apply too much.

Eight: insect pests

The main pest of desert rose is shell insect, which causes all leaves to fall off, plant growth point necrosis and even plant death when it occurs seriously. As soon as it is found that it is immediately wiped with water with cotton swabs, it can also be sprayed twice with 40% omethoate EC 1000 times or 50% fenitrothion EC 1000 times during spawning and incubation period.

Nine: diseases

Desert rose is mainly caused by leaf spot and root rot. When the leaf spot is serious, it can cause a large number of leaves to fall off. It can be controlled with 25% carbendazim wettable powder and 50% topiramate 1000 times. Root rot often causes root rot and death, which can be irrigated with 50% topiramine wet powder or 1000 times agricultural streptomycin.

Finally, it is necessary to pay special attention to: whether it is in the adaptation period or dormant period, watering should be controlled and fertilization should be suspended. When a large number of new buds are sprouted in spring, topdressing is added according to the growth situation. Winter can be placed in a sunny position, and keep the basin soil dry, the lowest temperature should not be lower than 8 ℃. Other seasons can be placed in the sun area, not in the shade to maintain, otherwise even if watering, fertilization is normal will be due to less light and yellow leaves fall off.
