As long as the orchid is basked in the sun for half a day, the leaves will wilt?

Orchids cannot grow without the sun, which is the law of plants, and orchids are no exception. When I talk about my experience in orchid farming, I often emphasize the importance of light to orchids. Orchids with poor long-term light are not only weak seedlings and easy to get diseases, but also not easy to have pregnant buds and flower.

In this way, the original intention of raising orchids is lost, and no one wants to raise only one pot of orchids that will not bloom.

About How to get the sun right for orchids? The amount of light is not weight and length, and cannot be expressed in a precise data, and our need for orchid light is judged by the natural growth of wild orchids.

All things are natural selection in nature, existence is reason, and there is no other better explanation and reason. Wild orchids mostly grow in a mix of broad-leaved forests and pine needle forests, and broad-leaved forests lose their leaves in winter.

Every year during the Qingming Festival, the broad-leaved trees on the mountain begin to sprout, and the light of the orchids slowly decreases, indicating that the season reminds the orchids of the need for shade.

In summer, the broad-leaved forest is shaded by the sun, very cool, because the trees of the orchid mountain are not too short, so the place where the orchid grows must be a cool breeze, and the farmer goes to the orchid many times in the summer to experience the feeling of the cool breeze.

After autumn, the broad-leaved forest begins to fall leaves once a year, the light of the orchid gradually increases, when the last leaf falls at the end of autumn, the orchid is basically in the sunshine all day long, of course, the sunshine time in winter is much shorter than in summer, which is also an important season for wild orchids to accumulate nutrients.

There are really some orchids that can't bask in the sun in some periods or in some specific environments, and the orchid seedlings will not grow stiff for a long time, and the orchid plants will fall into the whole pot. This is not empty nonsense, it is all supported by practice. So, what kind of sunlight is not suitable for orchids?

The good farmer made some statistics, which are now classified below.

After the orchid is planted, it is a slow seedling period within one week to ten days, during which the orchid root basically does not participate in the work, and the orchid plant is in a state of only consumption and no absorption. If you bask in the sun during the slow seedling stage, the water on the orchid leaves will evaporate too much, which will lead to water loss of the orchid plant. The most obvious feature is that the weeding is serious, and the wilting of the orchid seedlings is aggravated.

I have always advised orchids not to bask in the sun for 10 days after planting, and to maintain them in a cool and ventilated place, so that the orchids are easier to pass the slow seedling stage, so that they can survive smoothly.

It is because this kind of flower is suitable for a relatively shady and cold place, and it only needs to receive sunlight occasionally, so you don't need to receive too much, and you don't water it, so you must water it reasonably.

Don't give them the sun, let alone expose them to the sun, otherwise it is easy to let its water be lost, and the morning sun can be basked for a while.

Because orchids are originally suitable for growing in some cool and damp places.

What does a sunburned orchid look like? After reading it, you will know that it was all "confused" before.

The common cause of wilting is due to lack of water.

Either it is wilting caused by the strong sunlight, or it is wilting caused by too little water and not watering thoroughly, or your orchid is rotting from the roots, which is why it will become like this.

1. To ensure that the ventilation is in good condition (alternately use 2 fans to ensure 24-hour operation) - the strong wind outside is not good for orchids, it is recommended to set the wind power of the fan to the maximum after watering.

The general temperature should be kept at about 25 28 (summer standard), 20 25 in autumn (below 20 or above 30 is not good for orchid growth), and in winter try to keep it at 15 or more.

3. Fertilizer is based on summer, and fertilizer is applied on the back of the leaves every three days. Also, when watering weekly, fertilize the entire reed bark pot. Residual fertilizer can cause soft rot.

Therefore, after 1 hour of fertilization, wash off the fertilizer from the leaves with clean water. When using granular fertilizers, dilute the fertilizer with water until it is completely thawed. The fertilizer grains that are not completely thawed adhere to the surface of the orchid leaves, which may cause the leaves to soften.

There are two reasons for this, one is too much watering, and the other is that the planting material is too water-retaining.

Watering orchids is a regular task and an important part of the success of orchid cultivation. The potting soil of orchids should be kept moist frequently, but avoid excessive water content. In cultivation, the amount of watering should be decided according to the different seasons and different stages of orchid growth.

Generally from the spring, with the rise of temperature, the orchid turns into the vigorous growth period, the amount of watering should be gradually increased, every 1 2 days watering; The temperature is high in summer, and it is the peak period of orchid growth, so it is usually advisable to water once in the early morning and once in the evening, and do not water at noon. At the end of autumn, when the temperature begins to drop, the amount of watering should be gradually reduced, and it can be watered once every 2 3 days; The temperature is low in winter, most of the orchids enter the dormant period, at this time to control the watering, can be watered every 5 7 days 1 water, but the winter flowering Mo Lan and Han Orchid watering should be appropriately more.

To fertilize orchids, apply thin fertilizer, do not apply thick fertilizer, there is a saying of "clear orchids, turbid jasmine". Newly planted orchid plants should not be fertilized in the first year; Fertilization begins after Qingming in the second year until the beginning of autumn. Fully decomposed thin pancake fertilizer can be applied 1 or 2 times a month.

There are two commonly used fertilization methods for orchids, one is soil fertilization and the other is foliar fertilization. Foliar fertilization can make up for the lack of trace elements in orchids, but the frequency should not be too much, and it is better to do it once every 15 days during the peak growing season. Soil fertilization is divided into two situations, the fertilizer applied in the soil is basal fertilizer, and the fertilizer applied on the soil surface is called top dressing.

Don't have too much basal fertilizer to avoid fertilizer heat and damage to the roots.

What causes orchids to wilt? Today, let's talk about 5 of these factors and discuss them together.

Orchid leaf drying treatment method: stop watering, sufficient light, control pests and diseases

1. Stop watering

Orchid leaves are dry, it may be that watering is too frequent, resulting in stagnant water in the soil, so that the root system of the orchid is waterlogged and rotten, and it is necessary to stop watering, and drain the stagnant water in the soil, you can move the orchid to a ventilated and dry place for drying, in severe cases, you also need to change the pot and soil for the orchid.

2. Sufficient light:

Orchids need plenty of light during the growth process, if there is not enough light, it will lead to poor plant growth, which will make the orchid leaves dry and yellow, and the orchid needs to be moved to a place where it can be exposed to sunlight for maintenance, so that the orchid receives at least four hours of natural light every day.

3. Prevention and control of pests and diseases

Breeding orchids, if the plant is infected with the disease, it will cause the leaves of the orchid to dry up and yellow, you need to immediately cut off the leaves of the orchid with scissors to avoid the situation continues to deteriorate, you also need to spray the fungicide every other week, and wait until the leaves of the orchid are no longer yellow, which means that the pests have been removed.

Suitable temperature for orchids:

Orchids prefer a warm environment and can thrive at a normal room temperature of 15 to 25 degrees. In winter, the temperature is relatively low, move him into the indoor maintenance, the temperature is about 11 degrees, 5 to 10 degrees at night is appropriate, pay attention to ventilation when raising indoors, and the humidity is not too high. In summer, the temperature is too high, so don't be burned by the sun, and the temperature is controlled below 28 degrees.

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.
