What are the solutions for yellowing geranium leaves?
There are many reasons why geranium leaves turn yellow. Based on feedback from fellow gardeners, we have summarized some common causes of yellowing geranium leaves, along with the corresponding prevention and treatment methods.
First, you need to be familiar with the habits of geraniums: geraniums are drought-tolerant, dislike waterlogged conditions, and are heavy feeders. They hate water accumulating in the pot, so watering should be properly reduced in winter. Do not spray much water on the fuzzy leaves. In autumn and winter, apply a liquid fertilizer mainly containing phosphorus and potassium. They grow well at a room temperature of 15 degrees, and can safely overwinter at around 7 degrees.
If geranium leaves are wilting or showing soft rot, it is mostly caused by overwatering. If the leaves are relatively firm but have scorched yellow edges, it may be underwatering. Generally, both of these conditions can cause leaf drop.
Some gardeners also habitually mist their geraniums, not realizing that geranium leaves have many epidermal hairs on their surface and are not suitable for misting. Misting can cause geranium leaves to droop.
Also, during normal growth, as long as the whole plant is healthy, occasionally producing a small number of yellow old leaves is normal and no cause for worry. If a large number of yellow leaves appear within a short time, it usually means something has gone wrong with the root system, due to water or soil problems.
A bonus bit of gardening knowledge: in summer, the sun is strong and the temperature is high, which intensifies leaf transpiration. At this time, if the root system has not fully developed, or the amount of water the roots absorb is less than the amount the leaves need, the plant will become sick. In spring, the sun is not very strong, so this conflict is not very prominent yet. In summer, as temperatures rise sharply, this problem suddenly becomes obvious.
What to do when geranium leaves turn yellow? Prevention and treatment methods for yellowing geranium leaves
Previously, some gardeners reported that the geraniums they were growing had yellow leaves. What exactly causes this? In fact, there are many reasons why geranium leaves turn yellow. Based on feedback from fellow gardeners, we have summarized some common causes of yellowing geranium leaves, along with the corresponding prevention and treatment methods, for everyone's reference and learning.

If a large number of yellow leaves appear within a short time, it usually means something has gone wrong with the root system, due to water or soil problems.
When geraniums are in an overly hot environment, chlorophyll is destroyed, the leaves turn yellow en masse, and more of them drop. In severe cases, new leaves turn white or yellow and fail to grow large. At this point the leaves become thicker and smaller, reducing the amount of light they receive. (Excessive heat can also cause dormancy.) At this time, move the geranium to a shady spot and reduce its exposure to sunlight (but it should not be too deeply shaded either). This kind of plant will look rather bare. It can recover on its own once the weather turns cool. Overly cold weather. Excessive cold can freeze-damage the leaves; after the cells die, the leaves turn yellow and drop.
Now let's share a bit of gardening knowledge with everyone: in summer, the sun is strong and the temperature is high, which intensifies leaf transpiration. At this time, if the root system has not fully developed, or the amount of water the roots absorb is less than the amount the leaves need, the plant will become sick. In spring, the sun is not very strong, so this conflict is not very prominent yet. In summer, as temperatures rise sharply, this problem suddenly becomes obvious.
Summary: The above are the causes of yellowing geranium leaves and the solutions. We hope this is helpful to gardeners growing geraniums.
