Common problems encountered when growing green plants at home or in the courtyard are yellowing leaves. The yellowing of plant leaves is caused by multiple factors and cannot be resolved in a short time. If the leaves turn yellow, don't worry. First, observe the extent of the yellowing.

Mainly talking about the causes of yellowing in plant leaves and how to solve them.
Let me clarify that yellowing of plant leaves cannot be solved fundamentally, no matter who it is, even the most experienced flower bloggers cannot eliminate the issue of yellowing leaves. Factors such as watering, sunlight, and environment can all lead to yellowing, so it's not possible to address it directly. Yellowing of plant leaves is still relatively easy to solve.
During the growth period, plant roots consume a large amount of nutrients and water. The nutrients consumed include some trace elements, such as iron. Some plants grow very fast, and their roots can fill the pot within a short period of a year. Moreover, they tend to have a high number of flowers during the blooming season, making the leaves prone to yellowing.
What to do if the plant leaves turn yellow
Common houseplants like gardenia, jasmine, osmanthus, and hydrangea are prone to yellowing leaves. Their leaves tend to be more yellowish-green than the normal green of plant leaves, especially noticeable in gardenias and hydrangeas.
The yellowing of leaves is usually caused by a lack of iron in the potting soil, which means that the trace elements in the soil have decreased. When the plant roots cannot absorb iron, the leaves will turn yellow overall, and the chlorophyll content in the leaves will also decrease, slowing down the plant's growth rate.
Some gardening enthusiasts may wonder why their plants still lack iron even after fertilizing. The nutrients required by plants and trace elements are different. Fertilizers refer to nitrogen, phosphorus, and potassium, while trace elements include carbon, hydrogen, oxygen, calcium, iron, etc. A lack of iron will cause the leaves to turn yellow.
