What is the reason for the yellowing of crabapple leaves? What should I do with it?

Begonia flower is an endemic plant in China, known as "Guoyan" reputation, a wide variety, delicate and beautiful. So, what is the reason for the yellowing of crabapple leaves? What should I do with it? Let's get to know it together.

First, the reason why the leaves of crabapple flowers turn yellow.

1. Improper watering

Crabapple flowers in the summer high temperature dormancy period, the soil should be dry, can not be too wet, so it is necessary to reduce watering, otherwise it will lead to withered leaves and stems, the whole root will rot, and eventually the whole plant will die, but if the soil is too dry, it will lead to soil consolidation, roots can not breathe, resulting in leaf withering, so it should be watered properly according to the actual situation.

2. Improper lighting

The improper lighting here has two meanings. The first layer is insufficient light, and the crabapple flower likes the sun, but it is also not tolerant to shade. Insufficient light will cause the crabapple flower to synthesize chlorophyll, and the leaves will turn yellow. The second layer means that the light of the crabapple flower is too strong. This means that when the summer temperature is too high, the exposure to the strong light will also cause the leaves of the crabapple flower to be burned or even withered.

3. Lack of trace elements

If the crabapple flower lacks some trace elements in the process of growth, it will also lead to the yellowing of the leaves. For example, if the crabapple flower lacks iron or magnesium, the plant will easily turn yellow, because these two elements synthesize the important elements of chlorophyll. So if it is not caused by other causes of leaf yellowing, it is necessary to fertilize in time.

4. Improper fertilization

Fertilizer is needed during the growing period of crabapple flowers. If there is not enough fertilizer and there is no base fertilizer, the plant will become short, the leaves will become thin and light or red, and too much fertilization will lead to fertilizer damage, overnutrition and yellowing of leaves. Excessive fertilization during the summer dormancy period will also lead to yellowing of leaves, fertilization should be carried out at an appropriate time and conditions.

2. Treatment of yellowing of crabapple flowers and leaves

1. Rational watering

The crabapple flower will enter the dormancy state in summer, at this time does not need to pour too much water to the crabapple flower, can use the spray pot to spray water around the basin soil, but cannot completely do not provide water, except in summer, in the crabapple flower growth period should fully meet its water demand, normal rehydration.

2. Rational fertilization

Rational fertilization should be applied to the crabapple flower in early spring, and topdressing and replenishing nutrients should be given to the crabapple flower in early spring, and some special fertilizers can be used at ordinary times. If the crabapple flower has not been fertilized for a long time, apply light liquid fertilizer or compound chemical fertilizer every other week or so. At the same time, some trace elements can be properly added to the fertilizer. If iron deficiency, ferrous sulfate can be sprayed to supplement iron. If there is a lack of magnesium, you can apply some fertilizer containing magnesium.

3. Lighting

In the hot weather in summer, the crabapple flowers should be avoided from being exposed to the sun. In winter, when the crabapple flowers are put indoors in order to keep warm, they should be placed in a sunny place, not in a dark corner. If they are cultivated outdoors, they should be shaded at the right time.

The above are the reasons and treatment methods for the yellowing of crabapple flowers and leaves. If you also cultivate begonia, I hope you can know more about it!
