What to do if the leaves of the large leaved begonia flowers are rotten

Rotten leaves may be caused by too much moisture, excessive humidity and insufficient ventilation in the environment! Suggest improvements!

1. Like bright: In addition to the seedlings that need to be raised in a dark place in summer, they need to be in a bright place in other seasons, but avoid direct sunlight, otherwise the leaves will be scorched. Second, like moistness:

Iron cross begonia should not be sprayed with foliar water, in case of rotten leaves, but can be sprayed with ground water, in order to increase air humidity, the potting soil will be too dry will scorch the leaves, but too wet will also rot the leaves and rotten roots, in summer can be put on the pebbles in the water basin with pots, in order to increase humidity, which is very beneficial to growth. 3. Warmth: the growth room temperature is 20 25, 10 18 in winter, can be kept dormant, during this period must be controlled watering and fertilizer, summer should pay attention to ventilation.

Fourth, change the pot in April and May every year, it is advisable to loosen and fertile humus, you can add an appropriate amount of bone meal as base fertilizer, and you can apply thin liquid fertilizer once every half a month during the growth period, pay attention to the fertilizer water do not splash the foliage, otherwise the leaves should fester.

Obviously sick. Remove diseased leaves and spray. It's hard to say what kind of medicine to spray, and it is not ventilated indoors for a long time. In addition, if the soil is often too wet, I think your begonias will only die and not live.

Begonias are actually very easy to grow, they don't need to be taken care of, and they are more drought-tolerant, so they don't need to be watered often, which is very suitable for lazy people.

Is the edge of the leaf dry up? Find these 3 "reasons", the green branches and flowers continue to bloom!

1. Lack of moisture.

Reason: Begonia flowers prefer relatively moist flower soil conditions and cannot grow on dry flower soil for a long time. Otherwise, it may be dehydrated, resulting in undesirable phenomena such as leaf loss and leaf rolling.

Treatment: Hydrate it promptly. At first, water a small amount or branch water, and after it gets used to it, gradually increase the amount of watering to keep the soil slightly wet.

2. Nutritional deficiencies.

Reason: It needs nutrient support for its life activities, and if it is not fertilized for a long time, it will reduce nutrient consumption by shedding leaves.

Treatment: Apply some flower fertilizer to it and give it enough nutrients. Pay attention to the frequent application of thin fertilizer, do not apply thick fertilizer, otherwise it may cause fertilizer damage.

3. Insufficient light.

Reason: It prefers light, and if it is placed in the shade for a long time, it is easy to cause it to have dead leaves and fallen leaves.

Solution: Move the plant to a well-lit room and maintain it, and it will soon be able to return to normal.

4. Disease occurs.

Reason: When it is invaded by some germs, its normal physiological functions will become disordered, resulting in the problem of leaf loss.

Treatment: Cut off all its diseased leaves with sterilized tools, and then put it in a well-ventilated old banquet area, and use drugs for **.

Begonia flowers are rotten roots, and I personally think that it may be caused by too much watering, and it is recommended to control the water well.

1. Increase air permeability.

Reason: Begonia growth is required to have good air permeability, if the soil air permeability is not good, it will affect its growth, and in severe cases, it will also cause roots to rot.

Solution: Cut off the rotten root system, replace it with suitable soil, and properly loosen the soil in daily maintenance to increase soil permeability and let the roots of begonia breathe better.

2. Reduce the amount of fertilizer.

Reason: If you apply too much fertilizer, it will cause the roots of the begonia to rot and the leaves will turn yellow.

Solution: Water it generously and flush out the excess fertilizer. If the root rot is severe, remove it from the potting soil in time, cut off the rotten root system, and replant it in the new potting soil.

3. Deal with potting soil water.

Reason: If the amount of watering is too large and the amount of watering is not well controlled, it is easy to produce stagnant water in the potting soil, and there is stagnant water in the potting soil for a long time, which will lead to root rot.

Solution: Tilt the pot to drain the stagnant water, or spread dry soil on the surface of the potting soil, or use old newspapers to absorb water.

Fourth, re-cultivation.

Reason: If the rotten roots are found at an early stage, it can be remedied, but if it is found late, it is necessary to repot and replant.

Solution: Take out the potting soil in the begonia, cut off the root system that has rotted, be careful not to have new wounds when cutting, and then soak it properly with carbendazim, and then re-cultivate.

Dispose of the rotten roots, of course, in the process of cutting to control the force, do not cause new injuries due to your own negligence, put it in a windy place, transplant it into a new pot. A flower that is particularly easy to take cuttings can grow white roots in about half a month.

Begonia root rot is caused by improper watering, sometimes too much fertilization will also rot the roots, but the rotten roots caused by fertilization are not as many as the rotten roots caused by watering. The roots of the begonia are relatively fragile, and when they are found to be rotten, they are already rotten and cannot be treated, so they can only be re-cutting.

In summer, we should pay attention to the growth of begonias, and if the leaves appear yellow spots or rot, it is necessary to consider that the roots are rotten, and they can be saved by turning the pot in time. Many flower friends find that the leaves of begonias are dry or spotted, and they often think that it is a lack of water, and if they continue to flood the water, the rotten roots will be out of control.

First of all, we need to have a general understanding of the phenomenon of plant drying, from top to bottom, carefully observe, where the leaves are dry, and then, it is best to analyze the problem of leaf drying, according to the analysis to ensure the best response.

1. Dry soil If you find that the flower soil of the plant has become very dry, then it can probably be determined that it is caused by lack of water. In this case, many people may immediately replenish a lot of water, but in fact, the flowers that have been dry for a long time can not be watered immediately, which will not only damage the plant, but also may cause the death of the plant, it is best to use a watering can to simply replenish the plant, and then gradually increase the amount of water. In addition, begonia flowers do not need to be watered every day, as long as the soil is kept slightly moist.

2. Insufficient light In fact, begonia is a relatively sun-loving plant, if it does not receive light for a long time, the plant will definitely have no vitality and become sluggish and dry. At this time, what we need to do is to move the potted plants in the cold space to a well-lit and well-lit location to maintain, and the phenomenon of plant dryness will generally improve in about a few days.

3. Lack of fertility We all know that plants and people are the same, need to constantly supplement nutrition to grow better, if you find that your flowers and trees have become yellow leaves drooping, then it is almost certain that the plant should need to supplement nutrition, timely to the plant to supplement some potassium and phosphorus fertilizer, you can make the leaves of the plant gradually restore green, but we must pay attention to the use of the measurement, to prevent too much damage to the root system.

4. Caused by pests and diseases, no timely ventilation Finally, there is a possibility that the plant has been attacked by pests and diseases, in addition to watering more, usually do not pay attention to the hygiene of the potting soil, and do not timely ventilation is also very related, to solve this dryness, it is necessary to find pests and diseases in time, and then prescribe the right medicine, common, can be controlled with dimethoate or not Boer and other agents. Also, pay attention to ventilation! In this way, the plants can be healthy and healthy!
