What to Do When Cymbidium Leaves Turn Yellow
Today, the editor will elaborate on the related experience of planting flowers when Cymbidium leaves turn yellow. Let's take a look together.
What to Do When Cymbidium Leaves Turn Yellow
Cymbidium flowers often have a fragrance, with a wide range of color changes, usually light yellow-green with purple spots. The reason for the yellowing of Cymbidium leaves may be due to unsuitable soil, improper lighting, or incorrect fertilization. To deal with yellowing leaves, change the soil immediately if it is not suitable, apply a thin layer of fertilizer frequently, and water once a week.
What Causes Cymbidium Leaves to Turn Yellow
Cymbidium has 2-6 leaves, strap-shaped, glossy, 30-60 cm long, and 1-2.5 cm wide. The flowers often have a fragrance, with a wide range of color changes, usually light yellow-green with purple spots. The flowering period is usually from June to October. When the leaves of the plant turn yellow, the first sign is that the older leaves turn yellow, followed by the new leaves, and the edges of many leaves will turn from yellow to dry.Common Reasons for Cymbidium Leaves Turning Yellow
1. Unsuitable Soil - Cymbidium has fleshy roots with well-developed and robust root systems, so it requires high permeability in the soil. If planted in heavy clay soil, it will affect root growth, leading to a disruption in the nutrient transport channel between the roots and leaves. 2. Improper Lighting - Cymbidium is a兰花 variety that prefers sunlight. If it is kept in a shady area for a long time, the plant may lack photosynthesis, leading to a decrease in chlorophyll and yellowing of the leaves; if exposed to strong sunlight for a long time, the plant can easily get sunburned, causing the leaves to lose vitality. 3. Incorrect Fertilization - Too much nitrogen fertilizer can promote leaf growth, but Cymbidium has root nodules that can aggregate nitrogen elements. If the nitrogen content in the fertilizer applied during a certain period is high, it can cause fertilizer damage and yellowing of the leaves.What Causes Yellowing and Falling of Leaves:
Root rot is one of the reasons for yellowing leaves, as the leaves above the ground will not grow well if the rootstock rots and turns yellow or even withers. Additionally, the infestation of scale insects can also cause yellowing leaves, as the branches become covered with insects, affecting photosynthesis and leading to the gradual withering of the branches.Methods and Techniques for Dealing with Yellowing Cymbidium Leaves
1. Change soil and provide appropriate lighting - If the soil is not suitable, change it immediately. You can choose professional orchid-growing soil, which is suitable in terms of permeability and pH. Try not to use soil directly dug from the outside, as such soil does not have good breathability. In daily maintenance, place the orchid pot in a bright area, with full sunlight in spring and winter, and no need for shading. In summer and autumn, avoid direct sunlight at noon and provide some shading. 2. Apply thin layers of fertilizer frequently -兰花 dislikes heavy fertilization. Those who do not know how to fertilize should learn carefully. Fertilize promptly when needed, as correct or incorrect fertilization affects the growth of Cymbidium. Stick to applying thin layers of fertilizer frequently and do not be lazy, so that Cymbidium can grow robustly.How to Prevent Cymbidium Leaves from Turning Yellow
To prevent Cymbidium leaves from turning yellow, water once a week and deeply water once every two weeks.兰花 often develop yellow leaves or leaf tip burn during growth and development, which reduces their ornamental value. The causes of yellow leaves or leaf tip burn in兰花 are: too much or too little watering.兰花 prefer a humid climate, especially higher air humidity. If watering is insufficient for a long time and the air is too dry, the roots will shrink, weaken the absorption function, and cause an insufficient supply of water and nutrients.The above () introduces a comprehensive guide on what to do when Cymbidium leaves turn yellow, hoping to bring some knowledge about green plants to green plant enthusiasts.
