What are the reasons for the yellowing of carnation leaves?
Carnation flowers are bright and colorful, often used as cut flowers, and can be cultivated in greenhouses to bloom all year round. However, some friends have noticed the yellowing of carnation leaves during storage, which seriously affects their ornamental value. So, what are the causes of yellowing in carnations? How should we deal with it?
Unsuitable Soil
Carnations have high demands on soil conservation. If organic matter is insufficient in the soil used for cultivation or the soil is alkaline and has not been repotted for many years, yellowing of the leaves can occur due to poor soil fertility.
Solution: First, prepare some loose, breathable, slightly acidic soil to create a suitable environment for its growth. After removing the main stem from the pot and cleaning it, it should be replanted in the prepared soil and carefully cared for, which will soon recover slowly.
Excessive Sunlight
Carnations prefer a well-lit environment, but if exposed to the strongest sunlight for a long time, the intense sunlight can directly burn their leaves, causing them to turn yellow. In severe cases, it can lead to the entire plant withering and leaves falling off.
Solution: First, cut off the withered yellow leaves and place them in a well-ventilated semi-shaded area, strengthen water management, and appropriately spray water mist around to prevent green leaves from regrowing.
Overwatering
Carnations are afraid of excessive water. If watered too frequently during maintenance, their roots and stems can be completely soaked in water, leading to root and stem rot, reduced absorption capacity, and yellowing of the leaves without nutrients.
Solution: First, remove the pot and then cut off the yellow leaves and rotten roots. Since planted in a new soil layer that retains water, it can gradually recover.
Pruning
If the environment is suitable and there is sufficient fertilizer and water, carnations will grow excessively, and the leaves will grow lushly. This can cause some leaves to turn yellow.
Solution: Prune in time when the growth is vigorous to maintain internal ventilation and prevent insects as well as the yellowing of carnation leaves.
