Does Christmas cactus need sunlight? (Master these few tricks to meet the lighting requirements for Christmas cactus flowering)

Except when the temperature exceeds 32 degrees Celsius, the growth rate of Christmas cactus can be greatly improved by giving it full sun.

When caring for it at home, you must also ensure that it is in bright light during the day and give it more than 3 hours of weak light for good growth . When there is insufficient light, the branches and leaves are small and weak, and it will also cause it not to bloom.

1. Sunbathing in summer

In summer, when the temperature exceeds 32 degrees Celsius, the Christmas cactus will enter a dormant period. At this time, you can reduce the high temperature of the Christmas cactus and increase the humidity of the microenvironment by strengthening ventilation, providing appropriate shade, and spraying the leaves and the surrounding of the flowerpot.

When the temperature is high in summer and the sunlight is strong, the leaves may become dry and wrinkled, or the plant may lose water and die.

2. Sunbathing in spring and autumn

Spring and autumn are the vigorous growth seasons for Christmas cactus, and at this time it needs full sun care.

Spring is the time when leaf buds grow. If the plant is maintained in full sunlight, the efficiency of fertilizer will be greatly improved, which will promote the growth of branches and leaves.

Autumn is the time for flower bud differentiation . The sunshine time should be maintained for more than 6 hours. There should be a completely dark environment at night so that the Christmas cactus can effectively absorb and digest nutrients. It can bloom during the flowering period.

3. Sunbathing in winter

Even if the temperature drops in winter and the Christmas cactus is brought indoors for the winter, it is necessary to try to expose the Christmas cactus to sunlight. If the Christmas cactus is not exposed to sunlight for photosynthesis for a long time in winter, it will also cause the Christmas cactus to die.

The indoor ventilation is not good, and the Christmas cactus is in a low temperature dormant period. It takes a long time for the planting material to dry out when watering. Without the assistance of light to increase the evaporation of soil moisture, the Christmas cactus planting material will be moist for a long time, which will cause the roots to lack oxygen and rot.

The sunshine time of Christmas cactus should be kept at least 3 hours of bright light. The best sunshine time for growth is at least 6 hours of light a day, but avoid high temperature.

If flower lovers cannot grasp the seasonal light time standard, they can refer to the temperature. When the temperature is maintained at 15 to 28 degrees Celsius, they can give full sun. When the temperature exceeds 30 degrees Celsius, shade and increase ventilation to avoid strong light.
