What causes orchids to fall within a few days of flowering during flowering?

The flowering of orchids is caused by improper maintenance in the process of cultivation and management.

Due to the wide variety of orchids, their flowering period is basically all year round, and with the improvement of cultivation technology, the flowering period of orchids has also become relatively long. So do you know how to manage the flowering period of orchids?

1. Light. Orchids are also phototaxis when kept indoors, and their growth will be biased towards the side with strong light. Therefore, no matter what the season, we should rotate the pot regularly, so that all aspects of it can receive light equally, which is very beneficial to the ornamental nature of the plant or its own health.

During the flowering period of the orchid, we only need to give it some scattered light to meet the growth. Never leave it in the sun as it can cause burns. We can put it in a place with scattered light and keep it in a relatively cool growing environment!

2. Moisture. Seeing dry and wet is very conducive to the growth of orchids, especially when the buds are growing, the soil is too wet and will cause its growth to be slow, and even the flowers will fall. Soil that is too dry can cause poor growth.

We only need to see that the surface of the potting soil is white and dry, and when it is dry, we can water it thoroughly. Usually we can properly spray it to moisturize and cool down, especially when it is dry, it is very good for its growth.

3. Temperature. In the hot summer, it needs to be given a shady growth environment to reduce the poor growth caused by excessive evaporation of water or the rapid penetration of potting soil. When it is cold, we pay attention to keeping it warm from the cold, and put a plastic bag on it or put it in a warm place indoors, so that it can survive the winter safely.

4. Nutrients. Before the flowering period, we should start to apply a fertilizer rich in phosphorus and potassium, which can make the flowers bloom more beautifully and the fragrance is more fragrant. However, we should pay attention to the fact that it is not allowed to fertilize when flowering, and it is necessary to apply water-soluble fertilizer to fertile leaves before flowering, otherwise it is easy to cause flower drop.

5. Pruning. If there are more flowers during the flowering period, we can properly prune off some flowers that grow too densely, so that more nutrients can make the flowers grow better. At the same time, it also allows more nutrients to promote the growth of the plant itself, preparing it for flowering the following year.

The main reasons that affect the flowering time of orchids are ventilation and temperature. Ventilation is not only in the flowering period, in fact, it is very important at any stage of orchid cultivation, but the flowering season can reflect the importance of ventilation. Especially the environment of basking in the sun through the glass is a taboo for raising orchids, and orchid friends must pay attention to it!

In addition, the temperature at the time of flowering is also directly related to the length of the flowering period, and the shorter the temperature difference is, the shorter the flowering period of the orchid. In this regard, I also compared the orchids in the shed with the orchids outside the shed in the spring, and came to the same conclusion.

In addition to ventilation and temperature.

The above two points are common mistakes made by novice orchids, which will directly affect the length of the flowering period. In addition, there are several important points that will also affect the flowering time of orchids.

1. Water, orchids should not be watered too much during the flowering period, of course, if they have been stocked outdoors, they can be watered with the help of rain and dew, and there is no need to water during the flowering period. And friends who raise orchids on the balcony, you can't water too much during the flowering period, don't think that flowering consumes a lot of water to replenish, and the result of this is to shorten the flowering period.

2. Fertilization, spraying trime amino acids during flowering.

I have experimented with foliar fertilizer, as long as the concentration is mastered, there is no problem at all. However, watering liquid fertilizer (chemical fertilizer) will directly cause the flowering period to end. Because the petals of orchids are very sensitive, once they come into contact with fertilizer or are fumigated by fertilizer, they will end their flowering period early.

3. Don't dare to kill insects. When orchids bloom, they secrete sweet-smelling flower dew, which is meant to attract pollinating insects, but it also attracts pests, especially aphids.

If you don't spray insecticides in time, it will not only end the flowering period early, but also affect the growth of new seedlings after flowering, because aphids will suck the sap of the orchid plant. It turns out that orchids can be insecticide-applied during the flowering period, and the principle is the same as spraying foliar fertilizer.

Summary: It's hard to raise the orchid until it blooms, and who doesn't want to smell the fragrance for a few more days? Orchids are actually not that squeamish, as long as you don't violate its natural growth laws, you can make it bloom for the longest time.

The key is the above points: ventilation, temperature, moisture, fertilization, and insecticide.

There are many reasons why orchids do not bloom, the temperature is not suitable for day and night, the temperature difference between day and night is too small or the lack of light will make it unable to bloom, improper watering or wrong fertilization will also make it not bloom, orchids are in the seedling stage or the bulb is aging, it is also difficult to flower, pests and diseases will also make it not flower, and it is necessary to do a good job of prevention and control to make it grow and bloom normally.

Orchids need to have enough temperature difference between day and night, the temperature difference needs to be kept at about 10, the temperature during the day should be controlled at about 18 21, and the temperature should be guaranteed at about 7 10 at night, so that the orchid with insufficient temperature difference can grow and bloom quickly.

Insufficient light is also one of the reasons why orchids do not bloom, orchids do not receive sunlight for a long time during maintenance, which will make it difficult to give birth to flower buds for flowering, and the orchid should be placed in a sunny place, and properly accept about 2 3 hours of astigmatism, so that it can give birth to flower buds.

Improper watering of orchids during maintenance will also make them not bloom, too much watering to make them grow and drain in time to promote their germination buds, watering too little to properly replenish water, to avoid orchids in the flowering period of the bud, so that orchids can better flower.

Excessive fertilization leads to excess nutrients or too much nitrogen fertilizer, which causes the orchid shoots to grow vigorously and inhibits the differentiation of flower buds, thus preventing them from flowering. To fertilize appropriately, nitrogen fertilizer should be applied every half month in April and July, and phosphorus and potassium fertilizer should be applied in July and August to make its nutrients evenly flowering.

It is difficult for orchids to bloom while they are still in the seedling stage, and only adult orchids will produce beautiful flowers. Therefore, it is necessary to pay attention to providing careful care for it when maintaining, so that it can enter the maturity period as soon as possible, so that it can bloom.

The growth time of the orchid is too long, the bulb has begun to age, the root system is no longer robust, can not absorb nutrients well to provide nutrients for the growth and flowering of the orchid, it will make it not flower, to prune the root system in time, and pay attention to the repotting and soil to make the root system grow better, and absorb nutrients.

Orchids affected by pests and diseases such as leaf spot and whitefly will also not bloom, so it is necessary to carry out pest control in time, spray chlorothalonil solution and garlic homemade insecticidal solution, so that the orchid can be restored to health, so as to grow normally and bloom beautiful flowers.

1.Generally, the flowering period of orchids is usually around 30 days, while there are some orchid varieties that can last for about 60 days.

2.In fact, different orchid varieties have different flowering times, such as spring orchid usually blooms in February and March, while nine-headed orchid usually blooms in March and April, and Jianlan usually blooms between July and October.

3.In addition, the temperature of the orchid is controlled to a certain extent, so that its flowering time can be extended.

Orchid flowering can last 30-60 days, orchid peduncle has a lot of bracts, fragrant taste, thin and long leaves, large and thin petals, when breeding orchids, fertilizer should be applied every 30 days to provide nutrients for the plant, and watered once a month to keep the soil moist, daily maintenance, you can open more windows for ventilation, let the air circulate.

The flowering period of orchids is throughout the four seasons of the year, and it is also within a genus, which seems to have no certain pattern. For example, spring orchids mostly bloom in early spring; Orchid blooms in late spring; Jianlan blooms in summer or sometimes in all seasons, so it is called the Four Seasons Orchid; Hanlan blooms in late autumn and early winter; Melan blooms in winter, so it is also called primrose. But from the perspective of the whole orchid family, the flowering period is closely related to the climate.

Taking the orchids produced in Yunnan as an example, the flowering period is mostly between February and April. The rainy season in Yunnan is from May to October every year, and from February to April, not only orchids bloom more, but other plants are also like this, which seems to be an adaptation to the climate. This is the latter part of the dry season, which may be beneficial for insect pollination and to prevent rain from wetting or damaging the flowers.

In addition, the fertilized flowers at this time ripen in the next dry season, which is also conducive to the dispersal of seeds.

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.

There are several possibilities, generally due to lack of water or large water, affecting the growth of flower buds; Because the orchid has not been fertilized before the flower buds emerge, the flower buds cannot develop; There is also the location of the orchid, the light and ventilation are not good, so that the flowers cannot grow on time during the flowering period.

There are many reasons why orchids do not bloom, we need to investigate and analyze, a normal adult orchid, as long as it reaches more than two or three seedlings of conjoined plants, if cultivated properly, it can bloom under normal circumstances (a small number of orchid single seedlings can also bloom, thick roots and thin leaves of the Han orchid often have this phenomenon).

1. The orchid plant is still small and does not have reproductive genes. Some young seedlings that have not yet formed pseudobulbs need two years of vegetative growth to form pseudobulbs, and then germinate new shoots two or three times, and the branches can only bloom when three generations are in the same house.

2. Scattered planting will destroy the transmission habit of reproductive genes of orchids from generation to generation, so orchids should be planted in clusters, with fewer single leaves, less organic matter ash accumulation, and reproductive genes cannot be active. Generally, it is difficult to bloom without three generations of false bulbs in a row.

3. Improper drying and wetting, spring and summer and autumn are the vegetative growth period of orchids (but need to avoid the attack of plum rain and heavy rain), if the autumn is thousand, it will rush to vegetative growth. Winter is its dormant period, it should be dry, if it is too wet, it is easy to make the potting soil freeze and expand, squeeze the root group, affect the new shoots in the spring and summer of the following year, and affect its normal reproductive growth.

4. Too little light, limited accumulation of organic matter, can not supply the needs of reproductive growth. Although it is a shade-loving flower, it does not mean that there is no need for time, it only avoids direct sunlight and long light. Diffuse and scattered light (semi-shaded) is required.

It tends to grow in shady places, with dark green and lush leaves, but it is difficult and rarely flowering; The plants that grow in the south and in the middle of summer are slightly yellow-green in the leaves, but they have many flowers, and they are pretty and fragrant.

Why don't orchids bloom at home What is the reason?

The temperature is too high.

The cultivation site should be well ventilated, have shade facilities, and master the light. Shade nets and film are commonly used to prevent rain and shade, and better shade is required in spring and summer, and sufficient sunlight is given in autumn and winter, which is conducive to the growth and flowering of roots and leaves. Avoid direct sunlight or exposure.

Watering is the key to raising a good spring orchid, and the amount of watering depends on the temperature, the intensity of the light and the growth of the plant. Generally speaking, in winter, when the temperature is low and the humidity is high, it is watered less, and in summer, the plants are growing vigorously and the temperature is high. However, in summer, it is necessary to avoid showers and use film to block the rain.

Watering should be early in the morning.

Autumn rain is prone to black spot disease. In winter, it is better to water at noon on a sunny day. It is best to install automatic spraying facilities to increase air humidity, which is more beneficial to the growth and development of Chunlan.

The water used for orchids is generally rainwater and river water, and tap water must be used after entering the pool. Fertilization is required. Spring, summer and autumn, is the orchid growth period, can be more fertilization, from late March to late September, fertilization 1 time a week, the concentration should be light.

Orchids grow slowly in autumn and winter, so fertilizer should be applied less and once every half month. Spray a small amount of water after fertilization to prevent the fertilizer from staining the leaves. Fertilization must be done in the evening on sunny days, as there is a risk of root rot on cloudy days.

Generally, orchids are dormant in winter and do not need to be fertilized. During the growth period, you can also use granular compound fertilizer or "Huiyou" 15 15 30 potted flower fertilizer.

Pest control: Due to poor ventilation and high humidity, it is easy to cause black spot and mycosis hazards. Black spot disease often damages new shoots, and in severe cases, the whole plant dies.

In addition to strengthening ventilation and controlling air humidity, 600 times liquid spraying can be used with 65 dysen zinc wettable powder. Mycosis causes rhizome rot, which can be controlled by spraying 500 times of pentachloronitrobenzene powder. During the cultivation process, if scale insects damage the leaves, they can be sprayed with 1000 times of 40 oxidized dimethoate EC.
