Solution: Many people said before that Anthurium doesn't have to be kept at 14 degree. In fact, Anthurium grows day by day at 15 degrees, so it is not easy to suffer from cold damage so quickly. Specifically, when the temperature is lower than 10℃, Anthurium andraeanum will have side effects due to chilling injury. If you want to enjoy blooming again in winter, the temperature should be kept around 15 degrees. If you can safely spend the winter, it is generally not a problem to exceed the daily maintenance temperature 10 degrees.
Tip: Never buy Anthurium in areas where the indoor temperature is below 10 degrees in winter. Unfortunately, there is no guarantee after buying it. If the leaves are frostbitten, the scratched parts can be trimmed to keep the indoor temperature.
Second, the brown Anthurium caused by air drying likes wet growth environment. The air in the south of China is humid and the leaves are scorched, mainly in the north. The air is dry and the cold wind is like a knife. Therefore, people usually move indoors in winter for health preservation, but in areas with indoor heating, the doors and windows are closed, the indoor temperature is relatively high, the gas is easy to dry, and the leaves of Anthurium andraeanum are very easy to turn yellow and burn. Especially leaves.
Solution: Anthurium andraeanum should be maintained indoors in winter in the heating area of the northern region, and the wood planting guide should avoid the heat source, air conditioning warm air and the periphery of the heater to prevent the leaves from being burned by continuous high temperature. In addition, due to the high indoor temperature and low humidity, the leaves must be scrubbed with clean cloth dipped in warm water close to the indoor temperature at intervals, or sprayed with water every two days. On the one hand, it can increase the indoor humidity, on the other hand, it can eliminate the dust on the surface of fallen leaves and improve the contact surface with sunlight.
Tip: Watering Anthurium in winter must be done in the warm afternoon. It is not necessary to spray at night to prevent the risk of freezing of Anthurium andraeanum.
Third, the root system of Anthurium andraeanum caused by excessive watering is as chubby and fleshy as the flowers of Orchidaceae. This root system itself can store water, so it has strong drought tolerance. On the contrary, I am particularly afraid of waterlogging. You must be careful not to pour too much water under normal maintenance conditions. In addition, the temperature in winter is low and the water loss is slow. If people who like peony flowers are watered, the roots of Anthurium andraeanum will turn into muddy water. Long-term soaking will make the roots unable to breathe, cut off the transfer of nutrients, and make the leaves yellow or loose.
Solution: When the temperature is lower than 15℃, Anthurium andraeanum begins to gradually sleep and basically stops developing. At this time, the water demand is much less. Therefore, in North China where there is no heating in winter, it is necessary to control red and brown water injection and basically ensure B.
Reminder: Large area yellowing of Anthurium andraeanum was found to basically produce brown spot disease. At this time, the flower shop needs to stop watering, let the soil dry naturally, then move the ramets, cut off the withered roots, apply pesticides and fungicides, scrub the water and replant.
