The reason why the leaves of green radish turn yellow

Many friends like to place a few pots of green ivy at home. Not only do they look fresh and pleasing to the eye, but they also have the function of purifying the air and absorbing formaldehyde, which is helpful in improving indoor air quality. But for some people, the leaves of their green radish turn yellow. Let’s learn why the leaves of green radish turn yellow. ,

1. Strong light exposure causes leaves to turn yellow and dry

Pothos should not be exposed to strong light, especially during the high temperature period in summer. The strong sunlight will burn the leaves, and Pothos has poor tolerance to high temperatures. The most suitable growth temperature is 16-28℃. High temperature and dry air will accelerate the transpiration of the leaves, causing the leaves to lose water and turn yellow.

Solution: Pothos is more suitable for a cool environment and can accept some scattered light. It is best to receive light between 8 and 9 in the morning or after 4 in the afternoon. If the leaves of the green radish are injured by strong light, they should be moved to a cool place to recover immediately and avoid exposure to light in the short term. During the high temperatures in summer, you can also spray water on the leaves of the green radish regularly to lower the temperature, but be careful not to spray too much.

2. Improper watering causes yellowing of leaves

The growth of green radish requires sufficient water. If there is insufficient water, the growth of green radish will slow down and eventually the leaves will turn yellow due to lack of water. On the contrary, if you water too much, it will cause root rot, which will cause the leaves to turn yellow and black and fall off easily.

Solution: If you find that the leaves of the green radish are turning yellow and the bottom leaves are turning yellow as a whole, you should stop watering immediately and loosen the soil to prevent root rot, while maintaining ventilation. Usually, water the potting soil thoroughly at one time when it is almost dry. In a humid environment, you can water the plant every 2 days in summer, and reduce the frequency of watering in spring and autumn to once every 3-4 days.

3. Improper fertilization causes yellowing of leaves

Summer is the growing season for green radish, which requires sufficient nutrients. If the leaves of the green radish become lighter in color, light green or yellow, it may be due to a lack of nutrients. At this time, it is necessary to apply fertilizer in time, mainly nitrogen fertilizer. Pay attention to applying thin fertilizers frequently, and dilute the liquid nitrogen fertilizer before watering to avoid burning the roots. Some flower lovers do not dilute the fertilizer when applying fertilizer.

This leads to excessive fertilization, which injures the roots of the green radish and causes the leaves to turn yellow.

Solution: If excessive fertilization has caused the leaves of the green radish to turn yellow recently, you need to remove the green radish from the pot, clean the soil around the roots with water, check the roots, and cut off any rotten parts. Then replant it with sterilized new soil and place it in a cool place for maintenance.

In addition, fertilization for green radish should be adjusted according to the season. Increase fertilization appropriately before the spring growing season, apply fertilizer every 10 days; once every two weeks during the growing season; stop fertilizing in winter.

In short, green ivy likes a cool environment and avoids direct sunlight. Scattered light is enough for daily maintenance. Green radish is suitable for growing in a warm and humid environment. When cultivating it in soil, you should choose soil that is rich in humus, loose, fertile, and slightly acidic. During the maintenance process, once you find that the leaves of the green radish are turning yellow, you need to check the above aspects, find out the real reason, and take corresponding measures.
