What to do with anthurium rotten leaves, and how to deal with anthurium rotten leaves

The leaves are often sprayed with carbendazim sterilization and disinfection, put in a bright place indoors, the leaves are often sprayed with potassium dihydrogen phosphate, the leaves are greener, brighter and bigger, and the all-element plants grow better and more vigorously when they are watered.

Causes

1. Plants are damaged by frost.

1) Specific reasons: If you do not pay attention to cold protection in winter, and the plant is damaged by frost, then it is likely that the leaves will rot. This is a mild symptom, and in severe cases, the plant can easily freeze to death.

2) Solution: Move the plant to a warm place immediately. In winter, the maintenance temperature should not be lower than 10 degrees.

2. The air is too dry.

1) Specific reasons: This situation mainly occurs in winter. In winter, the air is generally dry, which can easily cause leaf rot.

2) Solution: You can move the position of the plant and place it in a place with higher humidity. You can also spray some water appropriately.

3. Watering too much.

1) Specific reason: If you water too much, resulting in serious water accumulation, then the roots will rot first. Next, the leaves will also rot.

2) Solution: Reduce watering immediately and see if the situation will be relieved. If there is still no sign of relief, the plant can be removed, the roots can be trimmed, cleaned, disinfected, and dried before potting.

4. Caused by disease.

1) Specific causes: There are some diseases that will cause leaf rot, such as "bacterial leaf spot" and so on. First some lesions will appear, then the lesions will expand, and then the leaves will rot.

2) Solution: Dispose of the rotten leaves. Then, spray streptomycin sulfate. Spray about once a week to 10 days.

1. Dispose of the medium in a timely manner.

1.The reason is that when it grows, it sometimes encounters sudden changes in the environment, such as unsuitable soils. In many parts of the north, the medium and water contain a lot of salt, so that it lacks the elements necessary for growth, and the leaves will rot over time.

2.At this time, we will find some oxalic acid solution to treat the medium to meet its growth needs.

2. Reduce watering.

1.The reason is that when people raise it, they sometimes keep watering to keep the medium moist all the time, and even produce water, which will cause most of the roots to rot, seriously affecting the normal absorption of nutrients by the plant, so the leaves will slowly rot. 2.

SolutionWhen it is found that the leaves are rotten due to excessive watering, the watering should be controlled immediately. If the situation is too severe, a part of the soil needs to be replaced.

3. Increase light.

1.The reason is that if you leave it in a cool place for a long time and don't get enough light, the slow growth will slow down and the leaves will start to rot. 2.The solution is to give it the right amount of light according to its growth needs.

Fourth, timely prevention and control of pests and diseases.

1.Reason: It is usually very resistant to pests and diseases, but without good feeding, it can also be easily infected with pests and diseases, such as snails and aphids, which can damage the leaves. 2.The solution can be sprayed with fungicide when it is judged, which can play a good preventive role.

Anthurium leaves rotten remedy:

1.Soil culture anthurium can be changed to grass peat, humus soil cultivation, grass and humus soil is acidic soil, usually watering socks water, a small amount of ferrous sulfate fertilizer can be added to the water, or vinegar to maintain the acidity of the soil.

2.When the soil-cultivated anthurium is overwatered and causes yellow leaves, the watering should be stopped immediately, and the root system should be removed from the pot to observe the root molding, and no rotten roots are found, then the depotted anthurium can be placed in a shaded and ventilated place to accelerate the evaporation of water in the soil, and then put it back into the pot for maintenance when the soil becomes not very wet.

3.Move to a well-lit place, such as near a south window, but avoid direct sunlight.

Breeding methods and precautions:

1 pot shouting calendar specifications of potted anthurium from small seedlings to large seedlings at different growth stages of the pot specifications are different, the seedling stage has generally been completed in the seedling company, we purchased the anthurium seedlings are seedlings (about 15 cm) or more, so, when planting in a pot, the choice of pots can be planted in a one-time 160 150mm red straight-edged plastic pot.

2. Cultivation substrate: The cultivation substrate must have strong water and fertilizer retention capacity, good permeability, no water accumulation, no toxic substances and can fix plants. Before planting, the substrate must also be thoroughly disinfected to kill pests and diseases and maintain its normal growth.

3 Anthurium is a shade-loving plant planted in pots, and a shading net with 75 shading capacity is required to prevent excessive light exposure. Double-plant planting is better than single-plant planting, and it is important to make the growth point of the core of the plant exposed to the level of the substrate when planting in pots, and at the same time, the plant should be avoided from contaminating the substrate as much as possible. When potting, fill the lower part of the pot with 4 to 5 cm of granular gravel and other materials for the drainage layer, and then add 2 to 3 cm of culture soil, and at the same time put the plant in the pot **, so that the root system is sufficient, and finally fill the culture soil to the pot surface 2 to 3 cm, but the growth point of the center of the plant and the leaflets at the base should be exposed.

Fungicides must be sprayed in time after planting to prevent the occurrence of Phytophthora and Pythium.

1. Improper watering If the amount of water is too much, or the water is too frequent, the soil will be in a wet state for a long time, and the roots will easily rot, affecting its breathing, and will also hinder it from absorbing nutrients, so its leaves will turn yellow and fall off. At this time, you should help it drain the water, and in the future, you should pay attention to the proper watering, not too much.

2. Improper fertilization.

If you fertilize it once for a long time or don't give it a new pot and new soil for a long time, the nutrients in the soil have been absorbed, and there is no new nutrients for it to feed, its branches will grow very thin and thin, and the leaves will become thin and yellow. At this time, it is necessary to replenish fertilizer and change soil in time.

If it is too fat, it is also not good, its leaves will become very thick and not smooth, and gradually turn yellow and fall off. At this time, you should immediately stop fertilizing, replace the soil, wash the roots with water, and plant them in the new soil.

3. Uncomfortable temperature.

If your home is in the north and the winter is very cold, even inside the house is very cold, its leaves will die and wither. If it is very hot in the summer, it will evaporate quickly, and the roots will not provide nutrients in time, and the leaves will wither and fall off. So keep it at a good temperature to ensure its normal growth.

Fourth, the soil is unsuitable.

In many places in the north, the content of salt and alkali in soil and water is higher, and the soluble iron in the soil is relatively lacking, and the leaves will fade green and fall off. That's when we need to change the soil.

5. Improper lighting.

If, like the friend at the beginning of the article, you leave it in an inappropriate place for a long time, exposed to the sun or left it in a dark area, it will be very weak, and the leaves will not grow as usual, and it will fall off.

6. Erosion of diseases and insects.

If a fungus attacks it, such as leaf spot, its leaves die easily, and if it is mosaic virus, its leaves will grow yellow spots. If insects erode it, such as scale insects and red spiders, the leaves will fade or shrivel and fall off. At this time, it is necessary to buy a special medicine for it, the proportion of the medicine should be small, the proportion of water should be large, and spray it several times.
