In fact, it is to control the temperature and humidity, bask in the sun sooner or later, and apply fertilizer properly.

When Anthurium andraeanum leaves are yellowed, withered and rotten, it may also be caused by bacteria. To remove bacteria, you can spray 0.3% solution of garlic juice, 0.2% solution of vinegar or 8-1000 times of carbendazim and chlorothalonil.

Indoor maintenance of Anthurium andraeanum should be managed in a semi-overcast, humid and warm environment, with the best temperature between 20 ℃ and 25 ℃, not higher than 33 ℃, otherwise it is prone to uncomfortable symptoms; the air humidity must be between 75% and 90%, and the leaves below 50% are prone to scorch edge drying.

But this can not solve the fundamental problem, because Anthurium andraeanum has such symptoms, because the maintenance environment is not suitable, Anthurium andraeanum should be managed in a semi-shady, humid and warm environment, and the temperature should be between 20-25 ℃, not higher than 33 ℃, otherwise it is prone to uncomfortable symptoms; the air humidity must be between 75-90%, and the leaves are prone to scorch edge drying.

The leaves of Anthurium andraeanum are easy to turn yellow, so pay more attention to conservation. If you want to maintain it well, you have to know the causes and rescue methods of yellowing leaves.

5. the low temperature leads to the yellowing of Anthurium andraeanum leaves.

If the indoor temperature is too low in winter, the leaves will turn yellow; if the room temperature is too high, the plant transpiration is too high, and the root water and nutrients are insufficient, the leaves will turn yellow.

Solution: keep the temperature in the greenhouse relatively stable.
