The leaves of the latest crabapple flowers turn yellow. what's going on?

Begonia flower is a unique plant in China, which is known as "Guoyan". As early as the pre-Qin period, it has been recorded in the literature of the pre-Qin period, it can be said that the history is very long, and the scope of planting in modern times is even more extensive. no matter it is classical garden or public green space, the fragrant appearance of begonia flower can be seen everywhere. But sometimes we will find that crabapple flowers grow suddenly the leaves will turn yellow, this is why? Next, the pro-agricultural network will introduce to you how the leaves of crabapple flowers turn yellow.

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, not too wet, so to reduce watering, otherwise it will lead to leaf and stem withering, the whole root will rot, and eventually the whole plant will die. If the soil is too dry, it will cause the soil to harden, the roots can not breathe, and the leaves will wither.

two。 Improper lighting

Here pro-agricultural network to say improper lighting has two layers of meaning, the first layer is not enough light, begonia flowers like the sun, but also not resistant to shade, lack of light will cause begonia flowers can not synthesize chlorophyll, leaves yellowing; the second layer means that the light of begonia flowers is too strong, which means that when the summer temperature is too high, the exposure under strong light will also cause the leaves of crabapple flowers 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.

4. Improper fertilization

Fertilizers are needed during the growing period of crabapple flowers. If there is not enough fertilizer and there is no base fertilizer, the plants will become short, and the leaves will become thin and light or red. Too much fertilization will lead to fertilizer damage, and the leaves will turn yellow. Excessive fertilization during summer dormancy can also lead to yellowing of leaves.

2. Treatment of yellowing of crabapple flowers and leaves

Knowing the cause of the yellowing of begonia leaves, how can we solve the problem of yellowing of crabapple leaves? Naturally, this is to start with the reasons and find the corresponding solutions. Here, the pro-agricultural network summarizes three points for you, including reasonable watering, reasonable fertilization and light. Let's take a look at it in detail.

1. Rational watering

Crabapple flowers will enter a dormant state in summer, at this time do not need to pour too much water to the crabapple flowers, you can use a spray can to spray water around the basin, but not completely without water. In addition to summer, in the growing period of crabapple flower, we should fully meet its demand for water and replenish water normally.

two。 adequate manuring

Rational fertilization in early spring, crabapple flowers should be fertilized, and topdressing and replenishing nutrients should be given after falling leaves in autumn. You can use some special fertilizers at ordinary times. If you haven't fertilized crabapple flowers for a long time, apply light liquid fertilizer or compound fertilizer every other week or so. At the same time, some trace elements can be added to the fertilizer. If iron is deficient, ferrous sulfate can be sprayed to supplement iron. If there is a lack of magnesium, you can apply some fertilizer containing magnesium.

3. Light

In the hot weather in summer, the crabapple flowers should not be exposed to the sun. In winter, when the crabapple flowers are put indoors in order to keep warm, you should pay attention to putting them in the sunny place, not in the dark corner.

These are the reasons for the yellowing of crabapple leaves summarized by the pro-agricultural network and the corresponding solutions, hoping to bring some help to you. More questions about flower planting can be found on the pro-farmers website, and friends can continue to follow us.
