What if the leaves of melon and chestnut turn yellow?
I. rational watering
Reason: melon chestnut is the most potted plant. If it is watered too much or too often, the leaves will turn yellow, and the wet soil will lead to lack of oxygen. Once lack of oxygen, its roots will rot, it will be difficult to breathe too long, and the leaves will turn yellow.
Solution: to control the amount of watering, it is best to wait for the yellow leaves to recover before watering. If you cannot control the amount of watering, you can use the way of spraying. Although it is necessary to reduce the amount of watering, it should not be watered for a long time, but should be watered reasonably.
Second, receive the right amount of light
Reason: melon chestnut likes the sun, but can not be exposed to the sun for a long time, being exposed to strong light will cause the leaves to turn yellow. If you put it in a dark place for a long time, it will not be able to carry out normal photosynthesis, and it will also cause the leaves to turn yellow.
Solution: receive an appropriate amount of sunlight in spring and autumn, but shade measures should be taken when the sun is strong in summer, or move it in astigmatism, which can be directly exposed to sunlight in winter.
III. Scientific fertilization
Reason: if you apply too much fertilizer or immature fertilizer, it will burn its roots, causing the leaves to turn yellow and fall off.
Solution: scientific fertilization should be applied during the growth of melon chestnut, thin fertilizer can be applied every 20 days, and some fully mature base fertilizer can be applied when changing pots, so that scientific fertilization can make it grow more luxuriantly.
Fourth, adjust the temperature
Reason: if the winter temperature is low, frost injury will occur, which will cause the leaves to turn yellow or fall off, and in severe cases, it will lead to plant death.
Solution: give it a growth environment of 20-30 ℃, the lowest temperature should not be lower than 5 ℃, if the temperature is low, you can use film or plastic bag to cover it, which can play a role in keeping warm.
