Smooth sailing is a perennial herb with green leaves and white flowers like fire buds, which are very fresh. Mainly used for viewing, but also for filtering indoor exhaust gas, which has a certain effect on ammonia, benzene series and formaldehyde.
The reason why the leaves turn yellow after smooth sailing
1, excessive water injection
Pour water too often, maybe too much water will be unlucky for it. If the roots of Yifan Feng Shui don't breathe well, it will easily lead to root rot, and the leaves will turn yellow and black.
2. The atmosphere is boring
The development of Yifan geomantic omen needs to adhere to high atmospheric humidity. If the atmosphere is too dull, it will cause scenes such as leaves wilting.
3. Bad lighting
Yifan Feng Shui needs good light in winter and early spring, so don't hide at this time, but gradually block the sun when the light is getting stronger.
If you browse in a hidden place, simply expose yourself to the sun, otherwise you will feel uncomfortable due to the rapid change of the situation, wilting, yellow leaves and even dying.
4. The temperature is uncomfortable
When the development temperature is lower than 15℃ or higher than 35℃, it is easy to show the yellowing of Feng Shui leaves.
5. Insufficient nutrition
In the early stage of development, if there is no nutrition in the soil, Yifan Feng Shui Hua will be stunted. If you don't change pots and soil for many years, the soil will gradually become barren and hardened, the roots will be underdeveloped, and the leaves will gradually turn yellow.
6. Improper fertilization
Yifan Fengshui applied raw fertilizer or agricultural fertilizer, causing fertilizer damage and hurting roots and yellow leaves.
7, the outbreak of pests
If it is beneficial to the risk of mites, the leaves of Yifan Fengshui show wilting, fading and yellowing.
How to remedy the yellow leaves after the smooth sailing?
1, lighting
Yifan Feng Shui insists on better illumination in winter and early spring, preventing direct glare in summer and autumn, and blocking sunlight by 70% in summer. If you browse in a hidden place, Fu Cheng simply puts it in the sun, otherwise it will be uncomfortable because of the sharp changes in the situation. Ordinary family farming can be maintained in semi-shade.
2. Humidity
Yifan Feng Shui needs high development humidity. In low temperature or boring weather, it can be treated by strengthening water spraying or sprinkling water in the air. Therefore, it should be covered with transparent plastic bags in winter. When the light is good, it is necessary to ventilate slightly or open a vent at the upper end of the plastic bag, otherwise the temperature in the bag will rise sharply.
Step 3 apply fertilizer
Fertilization should be thin and diligent, and it is best to use weak fat water instead of clear water for irrigation. Avoid applying concentrated fertilizer or raw fertilizer, and it is best to irrigate with clear water once after applying solid fertilizer, so that fertilizer damage will not occur and plants will flourish.
4. The temperature is not suitable
If the temperature is high in summer, it should be placed in a ventilated and cool center, spraying water on the leaves and taking cooling measures. The indoor curing temperature in winter should not be lower than 65438 05℃.
5. Pests
If there is no risk of mite damage, the leaves will have wilting, fading, yellowing and other adverse symptoms, and special chemicals for mites can be sprayed for continuous control, such as dicofol, nisolone and pyridaben.
