Why do the needles of the five-needle pine turn yellow?
This article will elaborate on the reasons why the needles of the five-needle pine turn yellow and share some green plant maintenance experience related to the rescue methods for yellowing leaves of the five-needle pine. Here is a comprehensive introduction.
Little Black has two potted five-needle pine landscapes at home, but a few days ago, he noticed that there is a problem with the leaves of these landscapes. All the branches have shown signs of needles turning yellow and drying, appearing as if they are about to "ascend to the west," which made him very worried. He wants to know what is happening and what are the causes of this phenomenon, and how to solve it.
Regarding this issue, let's explore several possible reasons for the drying of the five-needle pine and discuss the causes of this phenomenon and the solutions:
1. Overwatering
Yes, you read it right. Often, the drying of the needles of the five-needle pine is not caused by a lack of water but by overwatering. The five-needle pine is drought-resistant, and the potting soil should be kept slightly dry. Frequent watering can make the soil too wet, leading to a lack of oxygen in the soil, preventing the roots of the five-needle pine from breathing, which can cause suffocation and root rot, resulting in the needles turning yellow and drying.
Solution: Simply stop watering immediately, do not let water accumulate in the pot, and place the potted five-needle pine in a well-ventilated area. Pay attention to controlling watering in the future.
2. Sunscorch
In hot summer weather, water evaporates quickly. Many plants, if their leaves lack water, can easily dry under the sun, and the five-needle pine is no exception. If the potting soil is too dry and exposed to the scorching sun, the tips of the needles will scorch. If not watered in time, they can easily die. Note that in this case, the needles will not entirely turn yellow and dry, only the tips will be dry.
Solution: Water the plants that lack water in the evening, pay attention to the placement of the pot, ensure it is well-ventilated, and can have strong light but not direct sunlight.
3. Improper maintenance
The five-needle pine is best kept outdoors. Indoor lighting is often insufficient and不利于ventilation, which can affect the normal growth of the plant. Of course, if placed outside in direct sunlight, that is also not advisable. Light, water, and air circulation all affect the growth of its leaves. Insufficient or excessive water, poor ventilation, and lack of sunlight can all lead to drying and yellowing of the five-needle pine leaves.
Solution: Strengthen daily management, it can be kept in the shade of trees outdoors, the potting soil should not be kept moist for long periods, it can be slightly dry, and the leaf surface should be sprayed with water regularly. Once any problems are noticed, immediate preventive and rescue measures should be taken, such as removing the dried and scorched leaves, controlling water, and ensuring ventilation.
