There is a leaf edge rotten in the Gentleman s Orchid, what should I do with it?

In fact, the main reason for rotten leaves is not that we imagine that we have watered too much, because no matter how careless the owner is, he will rarely water a pot of water at one time to soak the soil, basically not enough watering. The most likely cause of leaf rot is actually the presence of pathogens, that is, lesions in some parts of the plant.

This damaged leaf should be cleaned up in time to prevent him from re-infecting other leaves. It is also necessary to apply some fertilizer to better ensure its growth trend.

This leaf can be plucked in its entirety to prevent infection, as well as to prevent infection of other leaves, and to disinfect the leaves.

The causes and treatment methods of the rotten leaves of the junzi orchid are as follows:

1. Too much water.

Orchid has a certain drought tolerance and has little water requirement at the seedling stage. During the growing season, you only need to water properly to keep the potting soil of the orchid moist. When cultivating Junzi orchid, watering should not be too much, too much water is easy to rot the roots of the plant, and even lead to the death of the plant.

If you find that the leaves are rotten, you need to stop watering immediately and turn the potting soil over. Place the plants in a cool, ventilated environment, or change the potting soil directly after disinfecting the plants.

2. The fertilizer is too thick.

Orchid likes fertilizer, but too much fertilizer will cause the roots of Orchid to rot, and further leaf rot will occur. It is necessary to follow the principle of "thin fertilizer and more application".

When maintaining the orchid, fertilization is particularly important in winter, the growth rate of the orchid is the fastest in winter, the nutrients need the most, and the application of winter fertilizer is conducive to the rapid growth of the orchid. Compound fertilizer can be added to the pot and applied to the plant every 20 days.

3. Insufficient nutrients in the soil.

The rot of the leaves of the orchid may be due to the fact that the soil has been used for too long and there is not enough nutrients in the soil. Under normal circumstances, the maintenance of the orchid requires repotting every two years. If you don't change the potting soil for a long time, the soil will not be able to provide nutrients to the plants in time, which is not conducive to the growth of the plants.

4. Germs or insect pests.

If it is caused by bacteria or insect pests in the cultivation soil, you need to take the plant out of the pot to find out which disease is causing it and then prescribe the right medicine. It is also necessary to cut off the residual leaves of the plant and place them in a cool and ventilated place for maintenance. Throw away the old potting soil and plant it with new potting soil.

5. The temperature is too low.

Orchid likes to grow in a warm environment, if you don't take cold measures after winter, it is easy to get frostbite on its leaves, and it will rot in serious cases. Whatever the cause of the rotten leaves, you need to prune the rotten parts, and if it is frostbite, you need to move it to a warm location to avoid continuous frostbite.

Pruning and disinfection: Rotten leaves of Monarch Orchid, you need to cut off the rotten leaves and spray carbendazim. Wrapping the wound:

Move the seedlings to a ventilated semi-shaded place and wrap the wound with plastic film. Top dressing fertilizer: Thin liquid fertilizer needs to be applied during the growth period to avoid fertilizer damage.

Precautions: Move the orchid to a warm room in winter to avoid frostbite.

1. Pruning and disinfection

Rotten leaves of Monarch Orchid, you need to prepare a sharp pair of scissors to ensure that the wound is smooth, and then spray alcohol on the scissors for disinfection and sterilization, and then cut off the rotten and blackened leaves of Monarch Orchid and burn them, and spray carbendazim on the fracture of the plant to avoid its infection.

2. Wrap the wound

After pruning the orchid, it is necessary to move the plant to a ventilated and breathable semi-shaded environment to avoid direct sunlight, so that the wound of the orchid can heal quickly, and the branches and leaves of the plant can be wrapped with plastic film to avoid water contamination and promote the healthy growth of the orchid.

3. Topdressing fertilizer

When cultivating Orchid, you need to apply thin liquid fertilizer or nutrient solution during the growth period of the plant to avoid fertilizer damage, and when watering the Orchid, you need to let the water flow down the edge of the pot, not sprinkled at the center of the leaf.

4. Precautions

When cultivating the orchid, it is necessary to move the plants to a warm room before winter to avoid frostbite, and when the outside temperature is too high, you need to open the window to make the indoor air circulation and reduce the probability of infection of the orchid.

Junzi orchid is now a common family potted plant, when there is rotten leaves, it should be treated in time, the soil is not appropriate, the sandy soil should be re-formulated, too much light should be maintained in a scattered environment, too much water should be drained to keep the soil moist, and the temperature should be too high to do a good job of cooling and keeping warm.

1. Re-allocate soil.

Orchid is a common family potted plant, which not only has high ornamentality, but also has a good purification effect on indoor air. So when the best way to deal with the rotten leaves of the gentleman's orchid, first of all, it is necessary to remix the soil, and it is best to use humus soil, river sand, and cinder according to 3:1:

Mix in a ratio of 1 and then put some small stones at the bottom best.

2. Reduce light.

Because the requirements for light are not very high, about 4 5 hours of light time a day, if the strong direct light or long-term exposure, resulting in the leaves can not carry out effective photosynthesis and the phenomenon of rotten leaves wilting, it is best to cut off the rotten leaves in time, and maintain them in an environment with good ventilation and astigmatism.

3. Reduce moisture.

Because the roots of the orchid plant are fleshy roots, which contain a lot of water substances, so the process of maintaining the orchid does not need to be watered frequently, if too much water leads to water accumulation in the potting soil and causes rotten roots, it is necessary to stop watering in time.

4. Reduce fertilization.

If the fertilizer is too large or very thick, it will also lead to the phenomenon of burning roots of the plant, so that the leaves can not absorb nutrients and the phenomenon of rotten leaves, when this phenomenon occurs, it is necessary to reduce fertilization in time, it is best to apply a thin fertilizer solution every other month, and then pour a small amount of water to mix.

5. Cool down and keep warm.

The growth of Junzi orchid is best to control the temperature at about 18 28, if the temperature is higher than 30 in the summer, the leaf water evaporation of the plant is faster, affecting the photosynthesis of the leaves and the phenomenon of rotten leaves, it is best to put it in a cool place or spray water mist on the leaves to increase humidity, and put it indoors to warm and prevent cold in winter.

6. Prevention of pests and diseases.

If the orchid is harmed by pests and diseases during the growth process, it will also lead to leaf rot. Because the pest mainly sucks the sap of the leaves or stems, it leads to poor leaf growth and rotten leaves. It is best to disinfect the potting soil from time to time, and then spray pesticides in time, cut off the branches of pests and diseases, and strengthen the circulation of air.
