Reasons for Yellowing and Withering Leaves on Crabapple (Begonia) and How to Fix Them

After the crabapple fruits, apply a quick-acting fertilizer as soon as possible to ensure sufficient nutrients for flower bud differentiation and storage of tree nutrition. After fruiting, the crabapple should be promptly disbudded, pinched back, or have its shoots twisted. For clustered branches, overly dense branches, thin and weak branches, drooping branches, leggy branches, and pest- or disease-affected branches, some or all should be pruned away.

During the high-temperature summer dormancy period, the soil for crabapple should be on the dry side and not overly moist, so watering should be reduced. Otherwise, it will cause leaf drop and stem withering, the entire root system will rot, and eventually the whole plant will die. 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.

During the growth of crabapple, growth may be hindered by the lack of a certain trace element. For example, if crabapple lacks iron, the leaves will turn yellow. A lack of magnesium can also cause leaves to turn yellow. These trace elements are important elements for synthesizing chlorophyll.

Crabapple likes sunlight and is not shade-tolerant. Insufficient light will prevent the crabapple from synthesizing chlorophyll, causing the leaves to turn yellow. When summer temperatures are too high, exposure to strong direct sunlight can also cause the crabapple's leaves to be scorched or even wither.

Fertilizer is needed during the growing period of crabapple. If there is insufficient fertilizer and no base fertilizer, the plant will become stunted and the leaves will become thin and pale or reddish. Over-fertilizing will cause fertilizer burn, and the leaves will also turn yellow. Applying too much fertilizer during the summer dormancy period can also cause leaves to turn yellow.

During the summer dormancy period of crabapple, watering should be reduced. You can spray water around the edge of the pot soil. But you can't give it no water at all. During the normal growing period, its water needs must also be met.

In early spring, fertilize the crabapple, and after leaf drop in autumn, apply additional fertilizer to replenish nutrients. Usually, you can use some specialized fertilizers. If the crabapple has not been fertilized for a long time, apply a dilute liquid fertilizer or compound chemical fertilizer about once a week. If the crabapple lacks iron, you can spray ferrous sulfate to supplement iron. If it lacks magnesium, you can apply some fertilizer containing magnesium.

In high-temperature summer weather, avoid exposing the crabapple to direct sunlight. In winter, when bringing the crabapple indoors to keep it warm, be sure to place it in a sunny spot and not in a dark corner.

1. Semi-shaded environment, place on the inner side of a balcony, at an east- or west-facing window

2. Water only after the soil has dried; each time water until water flows out

3. Pinch back frequently. Don't be reluctant to lose flower buds. Keep removing the tips of each branch so it will keep branching and become ball-shaped rather than growing into one long stem, which is not only ugly with few flowers but also easily broken. Spent flowers should also be pruned off promptly.

4. Frequently rotate the direction of the pot so it doesn't grow crookedly toward one light direction.

5. If the leaves are too dense, remove some. Poor ventilation makes it prone to mildew diseases.
