What to Do When the Leaves of the Crested Euphorbia Turn Yellow? Causes and Solutions
The crested euphorbia (Euphorbia neriifolia var. cristata) is a plant native to eastern India. It was originally a variant of the Indian spurge tree, but later people found this variety quite distinctive and gradually propagated it. The fleshy stem of the crested euphorbia is an irregular flat fan shape, and its branches and leaves are emerald green and dripping with freshness. However, when growing it, yellowing leaves sometimes occur, which greatly detracts from its ornamental value. What causes this? Below, Qinnong Network will explain it to everyone.
1. Temperature
The place of origin of the crested euphorbia is near the equator, so it cannot tolerate cold. Generally, it should be moved indoors in late autumn, and the temperature should be kept above 15°C, so the leaves are less likely to turn yellow. If the temperature drops below 10°C, the leaves may wither and yellow, so temperature is very important and must not be too low. Of course, too high a temperature is also undesirable.
2. Light
The crested euphorbia likes a sunny, well-lit environment. Apart from needing appropriate shading in summer, it needs sufficient light in the other seasons. Even in winter, sunlight must be ensured so that photosynthesis can provide the basic nutrients for the plant's growth. If there is not enough light, then over time the leaves will turn yellow and fall off.
3. Water
The crested euphorbia is a fairly drought-tolerant plant. Under normal circumstances, as long as it is not left unattended for a long time and allowed to wither to death, there will not be any major problem. For daily watering, follow the principle of preferring dry over wet. Especially in winter, watering must be strictly controlled, otherwise yellow leaves are very likely to occur.
4. Fertilizing
The crested euphorbia does not have a great demand for fertilizer, and the main principle is to fertilize less and use dilute fertilizer. When potting, some base fertilizer can be applied, such as some crushed solid fertilizer. When fertilizing, avoid raw fertilizer and concentrated fertilizer, otherwise it would be bad if it causes leaf drop. Fertilizing should also be stopped in winter, and only resumed after the beginning of spring the following year.
The above is what Qinnong Network has introduced about the causes of yellowing leaves in the crested euphorbia and the solutions. We hope it can be of some help to everyone. In addition, Qinnong Network would like to remind everyone here that the crested euphorbia itself is a toxic plant. Its sap is highly toxic, so it must never be eaten, and it must not splash into the eyes, as there may be a risk of blindness.
