The edges of the leaves are very brittle, and they will go bad when you touch them. What s going on

I didn't make it clear, there are no gods in it, and there won't be such a boring person to guess what you want to ask.

It looks like it is dehydrated, pay attention to watering in time, it is more drought-tolerant and dry and watered thoroughly, afraid of cold wind, afraid of cold and frost in winter, pay attention to heat preservation, and low temperature frost damage will also be like this.

The general causes of the yellowing of pothos leaves are introduced as follows for your self-reference.

1. The temperature of pothos needs a temperature of more than 15 in the growth environment, and there will be leaf yellowing below this temperature range. (It is currently the beginning of autumn not into the problem of low temperatures).

2. Watering requires that the potting soil be kept moist, not drought or long-term waterlogging. (Focus on checking whether the bottom of the pot can leak the remaining water during watering, if it can't leak, quickly use an iron drill to dredge the bottom of the pot from the bottom up.) 3. The light environment is mainly semi-shaded, and when the temperature is low in winter, it can be maintained in full sun, and when the sun is strong in summer, direct sunlight is absolutely prohibited.

However, if it is in a dark place for a long time, it will also have yellow leaves, so you need to adjust the position in time.

4. Fertilization requires less frequent application, not once fed, otherwise it is easy to cause fertilizer damage and rotten roots and yellow leaves.

5. Humidity - air humidity requirements are 60-85%, and when it is lower than 50%, the leaves are easy to yellow.

6. When the insect pests are harmed by red spiders and scale insects, the leaves are also easy to yellow, and the disease spreads very quickly, so it is necessary to spray special pesticides for prevention and control, in addition, frequent wiping of the leaves is a good way to prevent.

It cannot be exposed to direct sunlight and may be burned by strong light. In addition, there are small droplets of water at the tip of the leaf, so there is no need to water.

For example, there is a slight insect infestation and mechanical injury, which is relatively normal. Check for small bugs.

Because begonias are not resistant to direct sunlight and rain in summer, they should be shaded and rainproof, if they are exposed to rain for a long time, it is easy to cause flower stems and leaves to rot. In winter, it likes abundant sunlight and wide sunlight, and if there is not enough light, the growth is weak, and the plants are slender, and the leaves and flowers are colored. ,, fade, the light is too strong, the leaves shrivel, and the scorched spots appear, and when the fertilizer is insufficient, the plants are dwarfed and the leaves are red.

When watering the potted begonias, the potting soil needs to be dried before watering, such as keeping the potting soil moist for a long time, it is easy to cause root rot and cause blight. According to the characteristics of begonias, the preliminary judgment is caused by light, and you can judge the specific reasons yourself.

Because begonias are not resistant to direct sunlight and rain in summer, they should be shaded and rainproof, if they are exposed to rain for a long time, it is easy to cause flower stems and leaves to rot. Therefore, you should avoid direct sunlight and that's fine.

Key Value: The oil content of begonia kernels, the oil yield is 30%, there is no peculiar smell, and it can be eaten and can be used to make soap. The fruit is steamed and boiled to make preserves; It can also be used for medicinal purposes, has the effect of driving wind, smoothing qi, relaxing tendons, relieving pain, and can relieve hangover and phlegm, simmer and stop dysentery.

Flowers can be used as a seasoning for sugar sauce, and the flavor is beautiful. The bark contains tannin and can be used to extract tannin gum. The wood material is hard, which can be used for the bed Zheng Zaozhu.

In addition, the celery species is also a good material for garden greening.

If you keep it in the house for a long time, it may be like this, it should be exposed to a little sun, not too much.

During the growth of flowers, yellowing of leaves often occurs, and the reason is mostly caused by poor cultivation management. Too much water, too little sunlight, too much or too little fertilizer will cause yellowing of leaves, but the yellowing situation is different, and the causes should be carefully observed and analyzed, and corrected.

Water yellow The young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot.

Dry yellow The yellow of lack of water is different from the yellow of more water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.

Burning yellow strong sunlight directly on some shade-loving flowers (such as spider plant, hosta, etc.) is easy to cause the leaf tips and leaf margins of flowers to wither, and the sunny part of the leaves appears yellow spots. Move to the pubic area.

Lack of light yellow long-term shade environment, the leaves do not get enough sunlight, can not form chlorophyll, the whole leaf turns yellow and then falls off, supplemental light can avoid this disease.

Yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in the appearance of dry brown at the top of the new leaves, and the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and peeled off. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.

Lack of fat yellow is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow. Check the potting soil, if there is a dry knot, the soil should be changed, and the thin fertilizer should be applied frequently and some alum water should be poured in a timely manner.
