What should I do if the leaves of the latest star turn yellow?
Mantianxing is a relatively common cut flower plant, which is highly ornamental. If it is cultivated in a pot at home, it also looks pleasing to the eye, and in the process of maintenance, it is found that the leaves turn yellow, and not only when the old leaves are yellowing, the new leaves are also yellowing. What's going on? How to solve it? Let's take a look.
1. Overwatering
In the process of raising the sky star, the demand for water is more, so it often needs to be watered, but watering should also be mastered, and attention must be paid to the amount of water. If there is too much watering when watering, it is very easy to cause the soil full of stars to be too moist, even stagnant water, which can easily lead to root rot, resulting in dry and yellowing leaves.
Solution: in the cultivation of the sky star must be timely and appropriate amount of watering, watering must wait until the soil is dry or cracked before watering, and it is best to put the plant in a place with better ventilation conditions for maintenance, so as to avoid excessive humidity.
2. Weather reasons
The weather may also cause the leaves of the stars to turn yellow, which is more common in summer, because of the high temperature and heat in summer, the stars in the sky will stop growing and go into dormancy. At this time, if it is still the usual maintenance of watering and fertilization, then it is very easy to have rotten roots, resulting in dry leaves and yellowing. In addition, when exposed to strong light in summer, his leaves will also be damaged, causing them to turn yellow and dry.
Solution: so in summer maintenance must pay attention to cooling and shading treatment, can not let the plant receive too strong light, but also appropriately increase the watering frequency, can also spray water in the plant to increase air humidity.
3. Iron deficiency
The growth and development of plants is inseparable from nutrient elements, and the growth of stars is inseparable from iron. When the plant is lack of iron, it will cause its leaves to turn yellow.
Solution: when watering the star, you can add a small amount of ferrous sulfate to the water to subsidize it, but once you pay attention to the concentration of the solution, the content of ferrous sulfate is 1/1000, or you can spray it on the leaves. Spray once every 20 days, about 2-3 times can return to normal.
4. Growth is too dense
In the case of temperature, humidity and sufficient fertilizer and water, the growth of the star is quite fast, if the branches and leaves grow too dense, it will affect the permeability of the internal leaves, because there is no sunlight, the leaves will yellowing for a long time.
Solution: need some proper pruning, properly trim the overgrown branches to ensure that the inner branches and leaves are also exposed to light, and place them in a well-ventilated sunny place after pruning to expose them to fresh air.
