The cause of the loss of leaves in poinsettia and its solution

Poinsettia is not only beautiful, but also implies happiness. It is appropriate to give it to anyone as a blessing, but what if a poinsettia loses its leaves? Next, let's share with you the reasons and solutions for the loss of leaves in poinsettia.

The cause of the loss of leaves in poinsettia and its solution

1. the light is too strong

Poinsettia should not be exposed to strong light in summer. If the sun is too strong and the ventilation is not good, it is easy to lose the leaves of poinsettia due to high temperature drying.

Solution: in summer, poinsettia plants should be placed in a well-ventilated place, the distance between pots and pots should be kept at a distance of 50 centimeters, and water should be sprayed frequently on the ground, which can increase the humidity of the air and effectively control plant defoliation caused by high temperature and dryness.

2. The temperature is too low

Poinsettia prefers warm, humid, cool climate, not cold-resistant, suitable for growth of 15-20 ℃, winter night to maintain more than 15 ℃, not less than 5 ℃, otherwise the leaves are easy to fall off. If you open a window and blow a cold wind in winter, it will also lead to a large number of fallen leaves.

Solution: too low temperature is the main reason for the fallen leaves of poinsettia, so it is better to keep poinsettia in a higher temperature and stable environment in winter.

3. Overwatering

Poinsettia is afraid of dryness and waterlogging, the basin soil is too wet, plant canopy density is large, photosynthesis can not be carried out well, resulting in malnutrition and fallen leaves.

Solution: if poinsettia is properly watered, not too much, such as drainage in case of heavy rain, or move the pot plant into the room before the rain.

4. Too little watering

Poinsettia likes to be wet, if it is too dry and meets the hot sun, it will make the plant physiologically short of water, then the leaves will curl and a large number of fallen leaves.

Solution: poinsettia is watered every 2 days in spring. When the branches and leaves are luxuriant and growing fast in summer, the amount of water should be large and sufficient water should be provided.

5. Improper fertilization

Poinsettia likes fertilizer, needs more nitrogen fertilizer in the growing period, and the lack of nitrogen fertilizer will make the lower leaves of the plant fall off.

Solution: in addition to the base fertilizer applied on the basin, the thin pancake fertilizer and water that has been mellowed should be applied every 7 days or so within a month after picking the heart, not too much fertilizer should be applied during flowering, otherwise the phenomenon of leaf bud anxiety will occur. 40% fermented human feces can be applied before entering the house in winter.

How to prevent a poinsettia from losing its leaves

The low temperature is the main reason for the loss of leaves in poinsettia. For this reason, poinsettia should be maintained in a higher and stable environment in winter. Poinsettia grows very slowly, and the frequency and dosage of watering and fertilization are gradually reduced. In winter, poinsettia should be protected from freezing and keeping warm. Poinsettia should be watered every other week at noon on a sunny day, with the water temperature close to the soil temperature. Poinsettia should not apply more fertilizer during flowering, otherwise it will cause anxiety in the leaves of poinsettia. Before entering the house in winter, give poinsettia 40% fermented human feces.

When the leaves of other plants have withered, the leaves of poinsettia are still green and fiery red, just like an oasis in the desert, full of hope. Therefore, the flower language of poinsettia is an oasis. Born with the blessing of poinsettia, it is comforting and kind-hearted. If you point this heart at a particular person, he or she will immediately become your captive.
