What to do when hydroponic lucky bamboo leaves turn yellow? Let me teach you the remedies
Lucky bamboo (Dracaena sanderiana) is a common ornamental flowering plant with relatively high ornamental value. It is cultivated throughout China and is welcomed by many people. There are now many ways to grow lucky bamboo, including open-field cultivation, pot cultivation, and hydroponics. When caring for it at home, hydroponics is mostly used, but when growing lucky bamboo hydroponically, its leaves often turn yellow. So how do you save hydroponic lucky bamboo with yellowing leaves? Let's take a look together below!
1. Clean the water quality
When growing lucky bamboo hydroponically, if the water quality deteriorates or the water becomes contaminated, then the roots of the lucky bamboo will be affected by the contamination, thereby affecting the lucky bamboo's absorption of water and nutrients. In severe cases, it can also cause the roots of the lucky bamboo to rot, leading to yellowing of the lucky bamboo leaves. Therefore, we should promptly pour out the water and replace it with clean water. After about a week of care, it will improve somewhat, and when growing it hydroponically, we should also pay attention to doing regular water changes to avoid deterioration of water quality and contamination of the roots.
2. Light control
During the growth period of lucky bamboo, we should pay attention to maintaining a good light environment. Light is very important for the growth of lucky bamboo. If lucky bamboo grows in a dark environment for a long time without receiving sufficient light, then the chlorophyll content in the lucky bamboo leaves will decrease, causing the leaves to lose green color and turn yellow. Therefore, when growing lucky bamboo, we should provide it with sufficient light. However, do not let strong direct light hit it; mainly use scattered light to ensure normal growth of the lucky bamboo, avoid yellowing leaves, and improve the ornamental value of the lucky bamboo.
3. Reasonable fertilisation
Improper fertilisation is also a main cause of yellowing leaves in lucky bamboo. After excessive fertilisation, the tips of the new leaves of lucky bamboo will gradually turn dry and brown, and the leaves will be both thick and lustreless. Moreover, the surface will become uneven and difficult to spread out. If they are old leaves, they will gradually wither, turn yellow, and fall off. At this time, promptly change the water quality, cut off the yellow leaves, and stop fertilising to let it gradually return to normal. However, if fertilisation is insufficient, then the young leaves of lucky bamboo will gradually become lighter in colour, and at this time appropriate fertiliser should be added to meet the nutritional needs.
4. Supplement iron
During the growth process of lucky bamboo, its demand for nutrients is relatively high and also relatively comprehensive. In particular, various trace elements are also indispensable, and among them iron is a very important one. If iron is insufficient, then lucky bamboo is very prone to yellowing leaves. So if the yellowing of lucky bamboo leaves is caused by iron deficiency, then we should pay attention to dripping an appropriate amount of ferrous sulfate into the water. You can also put two nails in to supplement iron for the lucky bamboo, which can effectively alleviate the yellowing of lucky bamboo leaves.
The above is a brief introduction to how to save hydroponic lucky bamboo with yellowing leaves. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
