Reasons for Yellowing of Winter Flowers' Leaves
Let's share with you the reasons for the yellowing of winter flowers' leaves and a review of five solutions to address yellowing leaves, offering insights into the world of greenery. Let's take a look together.
Firstly, we need to understand why flowers develop so many yellow leaves. Only by clarifying this issue can we apply the right treatment. In fact, yellowing leaves are mainly caused by the following five reasons:
I. Watering
After winter begins, temperatures drop significantly, and the evaporation of moisture from the soil decreases, as does the transpiration of moisture from the surface of the flower leaves. If we continue to water as we did before, the soil in the pot will remain moist for extended periods, leading to a lack of oxygen in the soil. This can cause part of the plant's roots to rot, affecting the leaves and resulting in yellowing. This is also the most common mistake made.
II. Light
Some flowers that require strong light may develop yellow leaves if placed in a shaded area during winter due to lack of sunlight. This is similar to what happens when we place shade-loving plants in direct sunlight during summer. Remember to place the flowers in the sunlight when it's sunny to give them warmth and pay attention to their placement.
III. Fertilizing
Winter is a dormant period for many flowers, and their growth rate slows down, so their absorption of fertilizer is not as efficient. If we apply too much fertilizer during this period, it can overwhelm the plant, causing it to sustain burns and resulting in yellow leaves. So, remember to fertilize less during winter.
IV. Humidity
Those living in northern regions, take note! If there's heating at home, the air can become very dry. Flowers that prefer a humid environment, like orchids and jasmines, may develop yellowing leaves, curling edges, and spots. Use warm water that's roughly the same temperature as the room to gently spray the leaves. Remember to keep these flowers away from the heating. Increasing the humidity will prevent them from yellowing.
V. Ventilation
In autumn and winter, due to weather conditions, we often keep our windows and doors closed. In this enclosed, unventilated environment, the concentration of ethylene in the air can significantly increase, which can cause rapid aging of the flowers. When ethylene reaches a certain concentration, the leaves of the flowers may also turn yellow. Therefore, if the sun is shining in the middle of the day, be sure to open the windows to maintain good ventilation.
