The reason why the leaves of green radish turn yellow is revealed!1. Too much fertilizer!In the winter in the north, the temperature is low, and the green radish generally grows slowly or stops growing, so it is necessary to reduce or stop fertilizing. If too much fertilizer is applied, it will easily cause the roots and leaves to turn yellow and fall off. Solution:After winter, reduce the amount of fertilizer applied, and mainly spray fertilizer on the leaves, mainly through the stomata on the leaves. The fertilizer is absorbed through the stomata on the leaves, and the fertilizer effect can directly act on the leaves. Special fertilizers should be used for foliar application, as ordinary inorganic fertilizers are not easily absorbed by the leaves. 2. The light is too weak!Pothos is afraid of excessive sunlight, but the sunlight is weak in winter. If the green radish is kept in a dark place for a long time, the lack of chlorophyll will cause the leaves to turn yellow, especially the newly grown leaves. Solution:Try to place the green radish in bright places indoors such as the balcony and living room. If there is not enough light, you should move the green radish to a well-lit environment every once in a while, allow it to recover for a while, and then move it back to its original position. 3. Overwatering!If there is too much water in the soil or container of the green radish, it will cause the leaves to turn yellow, the leaves will appear dark yellow and dull, and even the roots may rot. Solution:In winter, strictly control the amount of watering, water appropriately, and wait until the soil in the pot becomes dry before watering again. Avoid water accumulation. 4. No ventilation!The growing environment of green radish requires ventilation and shade. The indoor temperature should not be too hot in winter. Pay attention to ventilation, otherwise dry heat will also cause the green leaves to turn yellow. It is necessary to open windows for ventilation and water more to ensure nutrition. 5. The air is too dry!The air in the heating room and air-conditioned room is too dry, which is not conducive to the growth of moisture-loving plants such as green radish. Therefore, different humidification measures can be taken if conditions permit to ensure the normal growth of green radish: 1. Place the plants close to the humidifier. The humidifier should be open for more than 5 hours a day so that the plants can enjoy the water mist sprayed by the humidifier. 2. Use a sprayer set to the mist scale to spray water on the leaves, stems and aerial roots of the plants several times a day; keep an appropriate amount of water in the flower pot tray to increase the local humidity of the plants through its evaporation; 3. Gently wipe the leaf surface with a cold wet towel or toilet paper or apply a light compress to the leaf surface for a short period of time (1-2 hours a day); 4. Cover the plants with a transparent plastic film to create the effect of a small greenhouse. Replenish the plants' moisture by evaporating the water vapor in the soil. This should not exceed 2 hours a day. Too long a time will affect the plants' ventilation and photosynthesis. Complete guide to caring for green radish in winterHow to keep the green radish green in winter, you also need to pay attention to the following 8 points:1. The green radish bought in winter is usually frozen, so the leaves will turn yellow quickly if placed indoors. After these frozen leaves turn yellow and fall off, they will grow again during the Spring Festival, so you just need to clean up the yellow leaves in time. 2. The newly bought green radish needs about a month to adapt to the new environment. It is normal for the leaves at the bottom to turn yellow. But remember: do not peel off the yellow or dead leaves directly. Cut them off from the middle of the petiole to avoid direct peeling, which will cause excessive water loss and increase wounds, causing the upper leaves to turn yellow again. 3. Pothos is not afraid of darkness, but it is best to move it to a place with good light in winter, but not in the sun! 4. If the room is too dry and stuffy, proper ventilation is required. 5. When watering, you can wet the pillars and there will be aerial roots on them. Spray some nitrogen fertilizer on the leaves from time to time and pour some diluted ferrous sulfate into the soil. 6. If the leaves are already very yellow! Be sure to control watering, too much or too little is not good! At this time, place the green radish in a well-ventilated and lighted place! 7. The green radish will turn black and die after being frozen, so try to ensure that the temperature is not lower than 10 degrees. 8. When the green ivy grows very long and climbs over the top of the column, you should cut it off or turn its head upside down to let it climb down. Don't let it grow randomly!
