Orchid leaves are a little wilted, what to do

There are many reasons why orchid leaves wilt, and it is not possible to generalize. The most common orchid leaf wilting and treatment methods are probably as follows: 1. Potting period.

Orchids need to go through two stages after planting before they can truly survive. Slow seedling, which is when the orchid is adapting to a new environment. At this time, it is not advisable to water too much, not to fertilize, and it is best to avoid direct sunlight.

Then it is the potting period, and whether the orchid can survive mainly depends on the potting period. The wilt starts at the tip of the leaf and extends downwards without noticeable dark spots.

Treatment: Improve the humidity and ventilation of the environment, and you can also spray foliar fertilizer once, it is recommended that potassium dihydrogen phosphate 800 times + urea 600 times, spray through the front and back of orchid leaves in the evening. Orchid two rot is a combination of stem rot and soft rot, although both have a rot word, but the mechanism of these two diseases is not the same.

Stem rot is fungal and soft rot is bacterial. The difference lies in the leaf wilt, stem rot is usually the whole leaf wilt, and the wilted leaf as a whole presents a "dry" feeling; Soft rot, on the other hand, begins to rot from the heart and base of the orchid leaf, and the withered part often feels sticky and wet. If the decay is dry, use a fungalicide (e.g., methyltobuzin); If the lesion is wet and sticky, use bacterial drugs (carbendazim is actually broad-spectrum and can also be used).

Or the moisturizing properties of the planting material itself are not very good. If you don't water for a long time, it may lead to a lack of water in the orchid plant, and the principle of this withered leaf is similar to that of weeding, but it is somewhat different when it is handled.

Orchid dead leaves can be appropriately reduced to watering it, keep the soil moist, generally orchids like to grow in a cool and humid environment, so the leaves are withered to reduce the light, it is too much nutrients in the process of growth will make it appear dead leaves, according to the situation to increase the material, at the same time to carry out insect and pest treatment.

1. Reduce watering

What to do with orchid dead leaves must first find the reason to solve, the leaf wilting of orchids is likely to be too much watering in the early stage, so that too much water in the roots leads to root rot and thus affects the normal growth of leaves, orchids like a moist environment, generally keep the soil moist, so in the later stage to reduce watering to avoid water accumulation.

2. Reduce light

Orchids like a cool and humid environment, long-term exposure to the sun, let it overshine will make the tip of the orchid slowly scorch and wither, so slowly transplant the orchid to a cool place or can be exposed to astigmatism to breed, so as to facilitate the growth of orchids, can avoid the situation of orchid dead leaves.

3. Add ** material

Too little fertilization in the process of maintenance will make the orchid wilt because of the lack of nutrients, and too much fertilization will cause the seedlings to burn, so in the later planting to control the number and amount of fertilization, according to the situation of the orchid appropriate increase of the first material, generally insist on watering every three months can greatly avoid the orchid due to the problem of fertilizer and withered leaves.

4. Insect and pest control

Orchids are easy to suffer from anthracnose and round spot disease during the growth process, the orchids suffering from this disease are first yellowed leaves, slowly withered, and finally the whole plant will wither, so to remove insects and pests in time, you can buy some professional drugs to spray on the orchid plants, which can alleviate the situation of orchid dead leaves.

Causes: 1. Overwatering. Although orchids prefer a humid environment, they should not be watered too much, resulting in rotten roots and dead leaves.

2. Less fertilizer or excessive fertilization. Less fertilizer will cause orchids to be malnourished and withered leaves, and excessive fertilization will cause seedlings to burn and withered leaves.

3. Excessive lighting. Orchids are shade-loving and yang-phobing flowers.

4. The humidity is too low. The humidity requirement of the orchid macro calendar is kept between 60-80%, and if it is too dry, it will cause dead leaves.

5. Low temperature. Orchids are suitable for survival in warm environments, and low temperatures or freezing can cause the orchid to wither.

6. Suffering from diseases or encountering pests. These can cause the orchid to wither leaves.

7. Change the pot and soil in time. Generally, orchids need to be repotted and changed once in about 2 to 3 years.

8. Air pollution occurs in the environment where orchids are cultivated. Orchid is one of the indicator flowers of air pollution, orange judgment, very sensitive to air pollution, such as soot, soot, smoke, paint, air fresheners, chemical synthesis preparations, sandworms, etc., a little carelessness will lead to orchid dead leaves and even death.

Solution to orchid wilting:

1. Orchid watering wax stall is dry and wet, do not water the tap water and rainwater that have just been connected. Water frequently in autumn, and the potting soil should not be too wet in winter;

2. Orchid fertilization should be rather light than thick, orchid foliar oil shows that there is no shortage of fertilizer, and the foliage is dull and dull to fertilize. Orchids grow slowly, and when they grow vigorously, fertilizer is applied every 7 days. No fertilization is applied every year when it is hot, cold and rainy;

3. The long-term humidity required for orchid flowers should not be less than 70%, and the dormant period in winter is about 550%; The air humidity is higher at night than during the day. Sprinkle or spray the foliage of the orchid with water in the evening to ensure that the foliage can be dried again at night;

4. Orchids like shade and should not directly accept too strong light. In summer and autumn, if you want to go into Shenfan for shade, you need to reasonably adjust the light to help it grow robustly;

5. The best temperature for the vegetative growth of orchids is 20 to 35 degrees Celsius, and below 15 degrees Celsius, it enters reproductive growth. Take care to regulate the temperature around the orchid;

6. Orchids should not use pesticides, and pollution-free methods should be used to prevent and control hail diseases and insect pests. For orchid leaves that have dried up, when they are not too serious, the method of manual pruning is adopted, and the dry part is cut off with sterilized scissors;

7. When the air quality is not good, ventilate in time and keep away from oil fumes.

Water or fertilizer shortage, less serious, can be improved with high-quality fertilizer.

When planting, hold the leaves with one hand, add nutrient soil with the other, and hold the base of the orchid plant slightly upwards to stretch the root system and shake the orchid pot at the same time. Let the cultivated soil penetrate deep into the rhizosphere; Continue to add soil and shake the pot to adjust the position and height of the plant. Press along the edge of the pot with your hands, but do not hurt the roots too much, continue to add soil and squeeze until the soil on the surface of the pot is 2-3 cm higher than the mouth of the pot, slightly steamed bread shaped.

The depth of the fill is traditionally believed to be shallow, and Huilan should be deep, but it is generally not buried and the leaf base on the false bulb is the degree. When the newly-haired orchid grows in the mountains, it leaves a clear mark on the soil surface, which can be used as a standard.

The size of the pot should also be commensurate with the size and number of plants, neither large pots and small plants, nor small pots and large plants. Generally, the number of plants is expected to be full in 2-3 years. The size of the plant is commensurate with the height of the pot.

It is not only conducive to growth, but also meets the requirements of ornamentation.

After planting, you can spread a layer of small stones or moss on the surface of the potting soil, preferably high-quality moss under the forest, which is not only beautiful, but also can regulate the water, and can also protect the leaf surface from being polluted by muddy water, and the new shoots will not be infected with the germs in the soil and rot their hearts; In addition, it can also slow down the erosion of the potting soil by rainwater and keep the potting soil loose.

After the planting is completed, the first water must be watered, the potting soil must be soaked, the water droplets should be small, and the impulse should not be large. If it is placed in a basin of water, do not soak it for too long. Once the potting soil is soaked, the pots are immediately removed and then placed in a shaded place for maintenance.

You can use "Yanwo microbial agent" + "root rooting agent" in the early stage, and the effect will be better when combined with Yanwo water-soluble fertilizer.

1. Proper shading: If the orchid has a dry problem, it may be because it has received too strong sunlight and has been sunburned. Cut off the parts of the plant that have been completely dried up, and then move the plant to a darker location with only scattered light for maintenance.

2. Spraying liquid: If you do not pay attention to ventilation when maintaining it, it may be infected by germs, so as to get sick and have the problem of dry leaves. Then prepare some sterilant and spray it on the cut and other diseased parts of the plant.

3. Increase watering: If the watering interval is too long when raising it, and the water-holding capacity of the planting material used is poor, then it may appear dry leaves due to lack of water. Prepare some clean water, wet the soil and increase the frequency of watering to keep the planting material moist.
