Reasons and solutions for yellowing leaves on crabapple flowers

The crabapple flower is a plant unique to our country, known as the "national beauty." As early as the pre-Qin period, there were already records of cultivating crabapple flowers in documents, so it can be said to have a very long history, and in modern times its planting range is even wider. Whether in classical gardens or public green spaces, the beauty of crabapple flowers can be seen everywhere. But sometimes we find that as the crabapple flower grows, its leaves suddenly turn yellow. Why is that? Below, Qinnong Network will introduce to everyone why crabapple flower leaves turn yellow.

I. Reasons for yellowing leaves on crabapple flowers

1. Improper watering

During the high-temperature dormancy period in summer, the soil for crabapple flowers should be on the dry side and must not be too moist, so watering should be reduced. Otherwise, it will cause leaf drop and stem withering, and the entire root system will also rot, eventually killing the whole plant. If the soil is too dry, it will cause the soil to harden, the roots will be unable to breathe, and the leaves will wither.

2. Improper lighting

Here, Qinnong Network wants to say that improper lighting has two meanings. The first meaning is insufficient light. Crabapple flowers like sunlight and are not shade-tolerant. Insufficient light will prevent crabapple flowers from synthesizing chlorophyll, and the leaves will turn yellow. The second meaning refers to too much light for crabapple flowers. This means that when the summer temperature is too high, exposure to strong sunlight will also cause the leaves of crabapple flowers to be scorched, or even wither.

3. Lack of trace elements

If crabapple flowers lack certain trace elements during the growth process, it can also cause the leaves to turn yellow. For example, if crabapple flowers lack iron or magnesium, the plant is very likely to turn yellow, because these two elements are important for synthesizing chlorophyll.

4. Improper fertilizing

Crabapple flowers need fertilizing during the growth period. If there is insufficient fertilizing and no base fertilizer, the plant will become short, and the leaves will become thin and pale in color or reddish. Too much fertilizing will cause fertilizer damage, and the leaves will also turn yellow. Too much fertilizing during the summer dormancy period will also cause the leaves to turn yellow.

II. Solutions for yellowing leaves on crabapple flowers

Now that we know the reasons for yellowing leaves on crabapple flowers, how should we solve the problem of yellowing leaves on crabapple flowers? Naturally, this means starting from the causes and finding the corresponding solutions. Qinnong Network has summarized three points here, including reasonable watering, reasonable fertilizing, and lighting. Let us take a closer look below.

1. Reasonable watering

Crabapple flowers enter a dormant state in summer. At this time, there is no need to water crabapple flowers too much. You can use a spray bottle to spray water around the pot soil, but you cannot give no water at all. Apart from summer, during the growth period of crabapple flowers, we should fully satisfy its water needs and water it normally.

2. Reasonable fertilizing

Reasonable fertilizing. In early spring, crabapple flowers should be fertilized, and after leaf drop in autumn, topdressing should also be given to supplement nutrients. Usually, some special fertilizer can be used. If crabapple flowers have not been fertilized for a long time, apply a light liquid fertilizer or compound chemical fertilizer about once every week. At the same time, some trace elements can also be appropriately added to the fertilizer. If iron is lacking, ferrous sulfate can be sprayed to supplement iron. If magnesium is lacking, some fertilizer containing magnesium can be applied.

3. Lighting

In high-temperature summer weather, avoid exposing crabapple flowers to direct sunlight. In winter, when placing crabapple flowers indoors to keep them warm, be careful to place them in a sunny spot and not in a dark corner.

The above is the summary from Qinnong Network of the reasons for yellowing leaves on crabapple flowers and the corresponding solutions, hoping to bring everyone some help.
