How to deal with the yellowing of Hawaiian coconut leaves

1. Fertilizer discomfort

To cultivate Hawaii, choose some rotten leaf soil, river sandy soil, and so on, and then mix them with a small amount of organic fertilizer to form a culture medium. During the growing season from March to October, liquid fertilizer or granular compound fertilizer was applied every two weeks to promote leaf growth and leaf color. Depending on the growth of the plant, the pot will be changed once every 2 to 3 years. If the above is not done, its nutrition will not be supplied, and it is inevitable that the leaves will turn yellow.

two。 Humidity discomfort

During the growing period of Hawaiian coconuts, the soil must always be kept moist and the air should not be too dry, otherwise the leaves will become dull and even yellow. When the air is dry, we can often spray water on its leaves to increase the humidity of the air. At the end of autumn and winter, the watering amount should be reduced appropriately to keep the basin soil moist and not dry, so as to enhance the cold resistance and overwintering ability of the plant.

3. Light discomfort

Hawaiian coconuts are very afraid of bright light, otherwise the leaves will turn pale or yellow. It generally likes the semi-overcast environment, and endure the shade for a long time, even if you stay in a dark place for 1 to 2 months. So when taking care of it at ordinary times, if you really give it too much sun, you can only accept some bright scattered light. Resistant to shade, the three seasons of spring, summer and autumn can be placed in any position indoors, and it is appropriate to put it in a sunny place in winter.

4. Watering is uncomfortable

Although it is moist, it can not make the water too sufficient, otherwise it will make the basin soil too wet, cause the roots to fester, nourish the nutrient transfer of the plant, and then make the leaves yellow. Therefore, watering must be appropriate in order to keep the leaf color thick green.

5. Caused by diseases and insect pests

When the temperature and humidity are extremely high, brown spot and downy mildew are easy to occur, which can lead to yellowing of leaves, which can be controlled by fungicides (such as carbendazim or topiramate 1000 times solution).
