Wenzhu, a common indoor foliage plant, has won the love of many people for its elegant posture and verdant leaves. However, many friends who raise bamboos may encounter a problem, that is, the leaves of bamboos turn yellow. So, why does Wenzhu have yellow leaves?And how should we deal with it?This article will answer this question for you.
First of all, we need to understand the reason why the leaves of bamboos turn yellow. In general, the yellowing of bamboo leaves can be caused by several reasons:
1.Lack of light: Bamboos are a light-loving plant, and if they are in a shady environment for a long time, their leaves will turn yellow due to the lack of light needed for photosynthesis.
2.Too much or too little water: Bamboo has a special need for water, which can neither be too wet nor too dry. If you water too much, it will cause a lack of oxygen in the roots and the leaves will turn yellow;Conversely, if you water too little, the leaves will also turn yellow due to lack of moisture.
3.Nutritional deficiencies: If you do not fertilize the bamboo for a long time, or if it is not fertilized properly, it may cause the leaves to turn yellow. Because the nitrogen, phosphorus, potassium and other elements in the fertilizer are necessary for the growth of bamboo.
4.Pests and diseases: If bamboo is infested by pests and diseases, the leaves may also turn yellow. For example, aphids can suck the sap of bamboo, causing the leaves to turn yellow.
After understanding the reasons for the yellowing of the leaves of bamboo, we can deal with it in a targeted manner.
1.Lack of light: If the leaves turn yellow due to insufficient light, we can try to move the bamboo to a place with sufficient light, but avoid direct exposure to the sun.
2.Too much or too little water: If the leaves turn yellow due to too much or too little water, we need to adjust the frequency and amount of watering. Generally speaking, you can water once a day in summer, and you can reduce the number of watering times in winter. At the same time, we also need to observe the moisture of the soil, and if the surface of the soil is already dry, it is ready to be watered.
3.Nutrient deficiencies: If the leaves turn yellow due to nutrient deficiencies, we can apply some fertilizer to the bamboo. Generally speaking, spring and autumn are the peak periods for the growth of bamboo, and fertilization is best at this time. When fertilizing, we can choose compound fertilizers containing nitrogen, phosphorus, potassium and other elements.
4.Pests and diseases: If the leaves turn yellow due to pests and diseases, we need to deal with them in time. For example, if it is an aphid infestation, we can use pesticides to control it.
In general, the yellowing of the leaves of the bamboo is not an unsolvable problem, as long as we find out the cause and take the right treatment method, we will definitely be able to restore the bamboo to a healthy state.
