What to Do When Desert Rose Leaves Turn Yellow? Causes and Solutions

In botany, the desert rose is also known as Tianbao flower (Adenium obesum). It is a succulent plant that prefers high temperatures, dry conditions and a sunny environment. It tolerates extreme heat but not cold. It gets the name desert rose because its place of origin is close to the desert and its flowers are red like roses. In mineralogy, desert rose is a kind of gypsum crystal, born in the desert, shaped like a blooming rose, in a thousand varied forms, magnificent and magical. Its main component is limestone, and because its geographical conditions for formation are special, its output is scarce. It is a purely natural wonder stone.

The desert rose is a common flowering plant that is highly favored and loved as a household potted plant. Yellowing leaves often occur. Summarizing the experience of most flower lovers, here are several situations in which leaves may turn yellow:

1. Not long after purchase, it is in an adaptation period. A small amount of yellow leaves is very normal and very common.

2. The flower pot is not breathable, or the pot is large while the roots are small. Avoid the potting soil being wet for a long time, which causes root rot.

3. When the temperature is low, in winter it enters a dormant period, that is, the leaves turn yellow and fall off, even falling until only bare stems remain.

4. It is relatively drought-tolerant. The amount of water each time must not be too much. If there is too much water, it is very easy to cause root rot and yellow leaves.

5. If the sunlight is too shaded, but also remember not to expose it to strong sun, the leaves are also prone to turning yellow, and flowering will be affected.

6. Poor ventilation and insufficient light will inevitably cause yellow leaves. In severe cases, the whole plant may rot and die.

7. Too much fertilizer. Fertilizer should be applied in an appropriate amount, not excessively.

What to Do When Desert Rose Leaves Turn Yellow: Figure Out the Cause of Desert Rose Leaves Turning Yellow

The desert rose gets its name because its place of origin is close to the desert and its plant form resembles a rose. It is a plant much loved for cultivation. In the process of artificial cultivation of desert rose, symptoms of yellowing leaves often appear. So what should be done when desert rose leaves turn yellow?

Introduction to the desert rose:

Desert rose (Latin scientific name: Adenium obesum.) is actually not a rose that grows in desert regions, and it has no close relationship or resemblance to roses. Also known as: Tianbao flower, Apocynaceae. This is a plant of the Apocynaceae family. Tianbao flower genus is a succulent plant, also called a succulent. It is a succulent shrub or small tree, up to 4.5m tall; the trunk is swollen. Leaves are simple, alternate, clustered at the branch tips, obovate to elliptic, up to 15cm long, entire, with a blunt apex and a short point, fleshy, nearly sessile. It prefers high temperatures, dry conditions and a sunny environment. It tolerates extreme heat but not cold. It gets the name desert rose because its place of origin is close to the desert and its flowers are red like roses; its places of origin are Kenya and Tanzania in Africa. It is beautiful when in full bloom and is often cultivated for ornament.

What to do when desert rose leaves turn yellow:

One: Not yet adapted to the environment

A newly purchased desert rose is in an adaptation period. The phenomenon of a small amount of yellow leaves is very common and a very normal thing. After some time, once it adapts on its own, it will be fine.

Two: Root rot

Plant roots need to breathe. Keep the soil loose. A flower pot that is not breathable easily causes root rot. Once the roots rot, the plant naturally cannot absorb enough nutrients. The solution is to cut off the parts that have already rotted, loosen the soil. If the root system has completely rotted, then there is no saving it.

Three: Overwatering

From the name desert rose, you can see that it is relatively drought-tolerant. The amount of water each time must not be too much, otherwise it easily causes root rot and thereby yellow leaves. After cutting off the rotted roots, control watering.

Four: Temperature too low

In winter, when the temperature is low, the desert rose enters a dormant period. The leaves turning yellow, drying up, and even falling off are all to reduce water evaporation and nutrient consumption. This is a self-protection mechanism, so there is no need to worry. If you want the desert rose to revive in winter, then move it into a greenhouse.

Five: Insufficient light

The desert rose is a sun-loving plant. Only sufficient light can ensure its normal growth. If you currently place it in a shaded place, quickly let it take a sunbath.

Six: Poor ventilation

Poor ventilation will inevitably lead to yellow leaves on the plant. In severe cases, the whole plant may rot and die. The solution is to take it out to “get some air”, that is, move it to a well-ventilated location, such as a balcony, a window, and so on.

Seven: Too much fertilizer

Too much fertilizer, on the one hand, makes the soil not breathable; on the other hand, the concentration of the solution outside the cells is too high, and the root cells lose water and die. The result in both cases is root rot, until death. Therefore, fertilizer should be applied in an appropriate amount, and remember not to apply too much.

Eight: Pests

The main pest of the desert rose is scale insects. When the infestation is severe, it causes all the leaves to fall off, the plant growth points to die, and even the plant to die. Once discovered, immediately wipe them off with a cotton swab dipped in water. You can also use 40% omethoate emulsifiable concentrate at 1000—2000 times, or 50% fenitrothion emulsifiable concentrate at 1000 times, and spray 1—2 times during the egg-laying period and hatching period.

Nine: Diseases

The desert rose is mainly harmed by leaf spot disease and root rot. When leaf spot disease occurs severely, it can cause large numbers of leaves to fall off. It can be controlled with 25% carbendazim wettable powder at 500 times solution, or 50% thiophanate at 1000 times solution. Root rot often causes the plant roots to rot and the plant to die. It can be controlled by drenching with 50% thiophanate wettable powder at 500 times solution or agricultural streptomycin at 1000 times solution.

Finally, special attention should be paid: whether it is in the adaptation period or the dormant period, watering should be controlled and fertilizing should be paused. When a large number of new buds sprout in spring, supplement with topdressing according to the growth situation. In winter, it can be placed in a sunny location, and the potting soil should be kept dry. The minimum temperature must not be lower than 8°C. In other seasons, it can be placed in a sunny area and must not be kept in a dark place, otherwise even if watering and fertilizing are normal, the leaves will still turn yellow and fall off due to insufficient light.
