What causes the leaves of white magnolia to turn yellow?
Today, I will explain to netizens why the leaves of white magnolia turn yellow and the reasons for the yellowing and withering of the leaves of white magnolia trees, as follows:
White magnolia is a relatively common plant in the south, both planted in the ground and in pots. It has dark green leaves, a long blooming period, and a strong fragrance. The most common problem encountered when caring for white magnolia is yellowing leaves, which is also the most troublesome. The leaves turn yellow and fall off easily. There are several reasons for the yellowing of white magnolia leaves;
The first point is water.
White magnolia is a typical succulent-rooted plant and should never be overwatered. Excessive watering can easily cause the potting soil to remain moist for a long time, which can lead to root suffocation. Root suffocation can cause yellowing and falling leaves. In the spring, summer, and autumn seasons, you can water thoroughly when the surface of the potting soil is dry. During consecutive rainy seasons, it is important to observe and drain the water in a timely manner. In winter, when the temperature is too low for maintenance, the amount of watering should be reduced.
The second point is sunlight.
White magnolia is a plant that likes sunlight. Many friends are afraid that it will turn yellow when exposed to the sun, so they choose to shade it. However, this is not correct. Besides shading in summer, it is recommended to have full sun in other seasons. Insufficient sunlight can cause the leaves to turn yellow, starting with the older leaves. This situation can be resolved by gradually increasing sunlight.
The last one is chlorosis.
White magnolia prefers an acidic growing environment. If the soil is alkaline, it is prone to yellowing leaves due to iron deficiency. You can use pH test strips or soil acidity testers to check. If the soil is alkaline, use iron sulfate promptly at a 1:1000 ratio, apply to the roots, and use it once every 7 days, for 2-3 consecutive times to improve the condition.
