What to do if the leaves of poinsettia turn yellow

The yellowing of poinsettia leaves is due to the soil being too dry.

When growing poinsettias, if there is too little watering, or the weather is dry and the light is strong, it will easily cause the leaves to turn yellow. Basically, this is related to the air humidity. In the hot summer or autumn, poinsettia needs to be placed in a sunny place, but it is best to water it sufficiently, and it is also necessary to replenish water in time and spray water to increase the air humidity.

The yellowing of poinsettia leaves is due to improper potting

When growing poinsettia, smaller flowerpots are generally chosen for initial planting. However, after a period of cultivation, the plant will slowly grow and become much larger with dense branches and leaves. At this time, the small flowerpot can affect the continued growth of the poinsettia, and the potting soil will lose nutrients, causing the leaves to turn yellow.

Therefore, when growing poinsettia, it is necessary to change the pot in time according to its growth conditions, and the soil needs to be loosened frequently to allow nutrients and water to better nourish the roots and avoid soil compaction.

Poinsettia cultivation temperature is too low

When growing poinsettia, you need to pay attention to the temperature, because poinsettia likes warm climate and is afraid of cold. The plant is easily frozen when it encounters cold weather, and the leaves will turn yellow. When growing poinsettias in winter, a higher temperature is required, between 15℃ and 18℃. It is generally higher when growing them indoors. Care should be taken to avoid cold winds and the heating can be turned on if necessary.

The yellowing of poinsettia leaves is due to overwatering

The yellowing of poinsettia leaves may be caused by excessive watering. Excessive watering will cause water accumulation in the pot. At this time, the roots of the poinsettia will lack oxygen and may rot, which will cause the leaves to turn yellow. Therefore, when growing poinsettias, it is necessary to water them reasonably, ensuring sufficient water while avoiding water accumulation. If root rot is found, the rotten roots must be cut off in time to avoid further infection.

The yellowing of poinsettia leaves is due to insufficient light

Poinsettia can be said to be a short-day plant, but during the cultivation period, it is best to maintain appropriate light. It cannot be deprived of sunlight for a long time, otherwise it will lose its green color and easily turn yellow. Therefore, it is best to place the poinsettia in a place with sufficient light for maintenance, which can promote its photosynthesis and make the leaves green.
