What to do with poinsettia leaves turning yellow

Poinsettia Leaves yellow is too dry basin soil

In the cultivation of poinsettia, if there is too little water, or the weather is dry and the light is strong, it is easy to cause its leaves to turn yellow. Basically, it's related to the air humidity. In the hot summer or autumn, poinsettia needs to be put in the sunny time, but it's better to be watered. In addition, water needs to be replenished in time, and spray water to improve the air humidity.

Poinsettia Leaves yellow is not timely flower pot

In the cultivation of poinsettia, the first planting is generally a relatively small flowerpot, but after a period of cultivation, the plant will grow slowly, grow up a lot, with dense branches and leaves, at this time, the small flowerpot can affect the continued growth of poinsettia, and the basin soil loses nutrients, which leads to the yellow leaves.

So in the cultivation of poinsettia, we need to timely change the pot according to its growth condition, and we need to loosen the soil frequently, so that the nutrients and water can better nourish the roots and avoid soil hardening.

Poinsettia culture temperature is too low

When cultivating poinsettia, we need to pay attention to a temperature, because Poinsettia likes warm climate and is afraid of cold. When it is cold, the plants are easy to be frozen and the leaves turn yellow. When cultivating Poinsettia in winter, you need a higher temperature, between 15 ℃ - 18 ℃. In general, indoor breeding is relatively high, you need to pay attention to avoid cold air, if necessary, you can turn on the heating.

Poinsettia Leaves yellow is watering too much

Poinsettia Leaves yellow, may be caused by too much water, too much water, will lead to water in the basin. At this point, the root of Poinsettia will be lack of oxygen, and may appear rotten roots, which will lead to yellow leaves. Therefore, when cultivating poinsettia, it needs to be watered reasonably to avoid ponding under the condition of sufficient water. If the phenomenon of rotten roots is found, the rotten roots should be cut off in time to avoid further infection.

Poinsettia Leaves yellow is lack of light

Poinsettia can be said to be a kind of short sunshine plant, but during the breeding period, it is better to keep the appropriate light, not long time without sunshine, so it will lose green, easy to turn yellow. So it's best to put Poinsettia in a place with sufficient light for maintenance, which can promote its photosynthesis, and make its leaves green.
