Why don t orchids bloom and what are the reasons why orchids don t bloom

The reasons why orchids do not bloom are as follows:

1. Light factor:

Orchid is a kind of flower plant that likes to grow in the shade of trees, so in order to avoid direct light damage to orchids, many flower friends will put orchids in a cool environment to maintain, but as everyone knows, if the light is poor for a long time, orchids can not effectively photosynthesize and convert energy, then it will cause orchid plants not to bloom.

2. Vernalization factors:

Orchid is a kind of flower plant with dormant stage, usually the winter and spring orchid to the low temperature dormancy period is called vernalization, in the vernalization settlement, the orchid will convert the growth nutrients in the body into reproductive nutrients, so the vernalization stage is better transformed, then the flower quality of the orchid will be better. However, if the orchid cannot enter the dormant state during the vernalization stage, it will affect the flowering.

3. Pest and disease factors:

When the orchid is infected with whitefly disease or leaf spot disease, and the orchid is not able to be given **, the plant's defense mechanism will judge that this is not a healthy flowering period, and it will not bloom. Therefore, when orchids are infected with pests and diseases, they must go to ** in time, otherwise it will not only threaten the healthy growth of orchids, but also cause orchids not to open.

4. Temperature factor:

When the temperature is too low, the orchid will not bloom, because in a long-term low temperature environment, it will inhibit the normal growth function of the orchid, and even enter a dormant stage, if the temperature is too low, it will easily cause the orchid to be frostbitten, so to promote the opening of the orchid, at least let the growth temperature reach more than 15.

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.

The reason why orchids do not bloom for several years is due to problems with flowering period, planting materials, nutritional needs, and temperature.

1. Flowering problem

There are many varieties of orchids, such as the common spring orchid, Jianlan, Huilan, Molan, etc., then the natural flowering period is also different, what season to bloom what flowers, this is not something we can forcibly change, if we maintain for a long time without flowering, it means that most of the relationship between this and the flowering period is due to the problem of our maintenance methods.

2. Planting material problem

The root system of orchids is fleshy roots, perishable, so the planting material must be drained and breathable, nutritious, many people maintain orchids, and the planting materials selected are often more arbitrary, which will lead to insufficient nutrient absorption by the rhizomes of plants, and the function of drainage is not strong. It is advisable to choose granular soil for matching, or to put a layer of ceramsite on the bottom of the pot.

3. Nutritional needs

Fertilizers are definitely needed for plant growth, and orchids are also fertilizer-loving plants, and they are just like babies with high nutrient requirements. It is required to use the corresponding fertilizer in different seasons, and it should not be used too much. We apply nitrogen fertilizer to the orchid to make it flourish, and we often say that phosphorus fertilizer can make it promote flower germination, and potassium fertilizer can make it strong and strong.

4. Temperature problem

Temperature is very important for orchids, because there are many varieties of orchids flowering is best low temperature and high temperature cross, if you can maintain a temperature difference of about 10 degrees, it will be more conducive to the differentiation of flower buds, and the temperature in winter and spring in some areas is too constant, which will also affect the normal pregnant bud flowering of orchids.
