The causes and treatment methods of the yellow leaves of begonia

1. The reason why the sun is too strong: crabapple flowers like the sun, but can not bear the strong light. If the sun is too strong in its environment, its sunny leaves will be sunburned and turn yellow. Treatment: cut off the yellowed leaves on the plant.

2. The reason why the light is too strong: begonia likes shade and cannot be raised in an environment with too much sunshine. If exposed to strong light, it can easily lead to slow growth and yellowing of leaves. Measures: you need to move it to a shady place with scattered light in time, but when the outdoor sun is too strong at noon, you can use a sunshade net to avoid the light.

3. Solution: replace the unsuitable soil and prepare the new acidic soil. Or add acid, loosen the soil appropriately and keep it loose. Improper watering reason: insufficient or too much watering will cause the leaves of begonia to turn yellow and scorched, do not water for a long time, the soil is very dry, can not absorb water.

4. There are many reasons for the yellowing of begonia leaves. If it is caused by too much watering, control watering; if it is caused by lack of light, increase the time of illumination appropriately; if it is caused by too little moisture, increase watering; if the soil is not suitable, replace the acidic soil; if it is caused by lack of fertilizer, increase fertilization.

What if the leaves of begonia become thinner?

More light will restore it. Reducing watering has a certain drought resistance, and water evaporates slowly in low temperature environment in winter, so there is no need to replenish water frequently. If you water it too often, the plants won't be able to absorb it all. Over a long period of time, there will be water, so the root system is easy to rot, can not normally provide water and nutrients to the leaves, and will slowly become soft.

At this time, it is necessary to replenish water to the plant in time and loosen the soil appropriately.

Lack of fertilizer, like fertilizer watering, it is better to add some nutrient solution, light and drought resistance is better in the bright part of the room.

Leaves alternate, elliptic to long elliptic, apex slightly acuminate, base cuneate, margin with flat obtuse teeth, surface dark green and glossy, abaxially grayish green and pubescent, petiole slender, base with two lanceolate stipules.

Brief introduction to the shape of begonia leaves: the leaf is oval or oval-oblong, 5-9 cm long and 3-6 cm wide. Apex acute, base cuneate or subrounded, margin spiny awn-serrulate, tooth tip glandular. Surface glabrous, sparsely pilose along leaf veins when young, abaxially densely yellow-white tomentose when young.

The leaves of crabapple flowers are oval to long oval, the leaf length is about 5-8cm, the tip of the leaf is obtuse, or acuminate, and the bottom is nearly round or broadly wedge-shaped. The edges of its leaves are also very fine serrated, young leaves will have short hairs, mature leaves do not.

The crabapple flower belongs to the rose family, the leaf is oval, the edge of the leaf is smooth, the color is green, looks like a small balloon. Begonia is a common deciduous tree, which belongs to Rosaceae. Beautiful pink flowers bloom in spring, luxuriant green leaves in summer and red or orange leaves in autumn, bringing visual enjoyment.
