What if the orchids don't bloom? 10 Tips for Winter Orchid Conservation

Many flower friends report that orchids raised at home do not blossom for a long time. Why? The cold weather in winter can easily cause the problem of orchid culture, and florists should take more careful care. The following editor will talk to you about the 10 key points of orchid maintenance in winter.

1. Diseases and insect pests

The common diseases of orchids are anthracnose, leaf spot, leaf blight, blue lice and so on. If there is no prevention in advance, it is easy to cause orchid plant diseases and pests to harm the whole plant. Therefore, it is necessary to make a schedule and spray regularly.

2. Insufficient supply of nutrients

If the one-sided pursuit of air and water permeability makes the water retention of the cultivation medium poor, the amount of fertilizer applied will leak as much fertilizer. Therefore, it is necessary to change the cultivation medium properly and apply additional fertilizer in time in order to contribute to the budding of orchids.

3. The plant is too small

Many orchid plants do not blossom because the orchid seedlings are too small to reach the reproductive stage. Some seedlings that have not yet formed false bulbs must grow for two years to form false bulbs before they can bloom.

4. Improper drying and wetting

The orchid is dormant in winter, which is suitable for the dry environment. If the humidity is too high, it is easy to cause the rotten roots of the orchid and affect its flowering in the coming year.

5. The temperature is too low

The roots of potted orchids are prone to frostbite in winter. Even if it doesn't die, it won't blossom. The best ambient temperature in winter is 0: 3 ℃.

6. Excess nitrogen fertilizer

If too much nitrogen fertilizer is applied, the plants will grow too much, the leaves will be too fat, and the reproductive growth will be inhibited. The correct fertilization should be dominated by nitrogen fertilizer from the end of April to early July, supplemented by phosphorus and potassium fertilizer, dominated by phosphorus and potassium fertilizer and supplemented by nitrogen fertilizer from the middle of July to the end of August, and no fertilization in winter.

7. Nutrient dispersion

If the orchid plant blossoms too much in the first year and bears seeds, and there are too many new buds in the second year, it will cause the dispersion of nutrients, so it is necessary to sparse buds and buds in time, and do not allow seeds, so as to ensure that they will bloom in the coming year.

8. The hibernation period is too short

The orchid will enter the dormancy period after entering the winter, but if the orchid is moved indoors too early, it will postpone the hibernation, and the high indoor temperature will shorten the dormancy time of the orchid, disrupt the biological clock of the plant, and inhibit the flower bud differentiation.

9. Be affected by air pollution

Orchids like to grow in a clean environment, if often polluted by air, smoke and other pollution, it will lead to poor plant growth and difficult to bloom.

10. Improper fertilization season

If fertilizer is continued to be applied in late autumn and winter, the vegetative growth of orchids will be stimulated and can not be dormant normally, weakening vernalization, resulting in physiological function disorder. Orchid fertilization is mostly carried out between Grain Rain and the Beginning of Autumn.

[the reason why orchids don't blossom] what if orchids don't bloom?

There are many reasons why orchids do not bloom. Orchids need to be investigated and analyzed. For a normal adult orchid, as long as it reaches more than two or three conjoined plants, if it is cultivated properly, it can blossom under normal circumstances, but the actual orchid is not very easy to raise. In the process of orchid cultivation, it is easy to rot the root and rot the stem or the orchid will not blossom if handled improperly. In general, if the stem buds of orchids rot, do not deal with them, then the roots and yellow leaves will rot, and the orchids will not blossom in the end.

There are five reasons why orchids do not bloom. 1. The orchid plant is still small and does not have flowering.

The plants of orchids are still small and do not have reproductive genes. Some young seedlings that have not yet formed pseudobulbs can bloom only after two years of vegetative growth to form pseudobulbs, and then germinate new shoots two or three times, and the branches are three generations in the same house.

2. Orchid ramet destroys fertility genes.

Ramet planting will destroy the transmission habit of reproductive genes of orchids from generation to generation, so orchids should be planted in clusters, less leaves per plant, less ash accumulation of organic matter and no active reproductive genes. Generally speaking, it is difficult to blossom without three generations of pseudo-bulbs in the same house.

3. Orchids do not blossom: the environment does not adapt.

Improper dry and wet, spring and summer and autumn is the vegetative growth period of orchids (but need to avoid plum rain and rainstorm), if the autumn is too thousand, it will make vegetative growth. Winter is its dormant period, which should be on the dry side. If it is too wet, it is easy to make the basin soil freeze and expand, squeeze the roots, affect the new shoots of the following spring and summer, and affect its normal reproductive growth.

4. Orchids do not blossom: too little light

The light is too little, and the accumulation of organic matter is limited, which can not supply the needs of reproductive growth. Although Lanhuo is a shady flower, it does not mean that it does not need time. It only avoids direct and long light. But need to diffuse, scattered light (semi-shade). Plants that tend to grow in the shade have dark green leaves, but they are more difficult and less flowering, while those growing in the south and mid-summer shade are slightly yellowish-green, but with more flowers, and are gaudy and fragrant.

5. The orchid itself does not blossom

Orchids can not bloom for their own special reasons, or a very small number of orchids do not like to blossom. This phenomenon has appeared in various orchid species, and I have also encountered: in 2004, a vegetarian Jian Lan, which came down the mountain, has been cultivated in this garden for six or seven years, and it has developed to more than a dozen pots. I have never seen flowers until now. This is probably the sterility of plants (orchids).

What if the orchid does not blossom? 1. Cultivate strong seedlings

In general, the spring orchid for ornamental flowers cannot be divided into single seedlings for propagation. It is best for three seedlings to be connected to the pot, so that strong seedlings can be cultivated.

2. Enhance the illumination

Light is the main factor affecting the growth and flowering of orchids. Plants rely on sunlight for photosynthesis to produce indispensable nutrients for their growth. The growth of Cymbidium and the formation of flowers need sufficient light. Sunlight can help orchid leaves carry out photosynthesis, create "food" and support the growth and flowering of orchid seedlings. In addition to summer and early autumn, Chunlan can not let direct sunlight in other seasons, which can not only make the orchid seedlings healthy and strong, but also strengthen the bulbs and promote the propagation of buds. Orchids with exuberant growth are easier to draw buds.

3. Master watering

Water is one of the material bases for plant growth, but there should be a limit to the amount of water. Watering should not be fixed for a fixed time, but should seize the opportunity. If it is dry, it will be watered thoroughly, and when the orchid basin is dry, it will be watered. This is the basic principle of watering. When watering, it should be noted that the temperature of the water should be similar to that in the orchid basin of the orchid place as far as possible. Summer and early autumn can be watered in the morning and evening, while in winter at noon, the aim is to reduce the temperature difference between water and orchid pots. Spring orchids should generally be watered during the growing period, and watering should be strictly controlled before flower buds are formed.

Why don't orchids blossom? What if orchids do not blossom? with more and more orchids growing, of course, there are many problems in the process of conservation. before, some flower friends asked about the reasons why orchids do not bloom, in fact, there are many reasons, and orchids need to be investigated and analyzed. a normal adult orchid, as long as it reaches more than two or three conjoined plants, if cultivated properly In general, it can blossom (a small number of orchids can also blossom, and cold orchids with thick roots and fine leaves often have this phenomenon). This article focuses on introducing the reasons why orchids do not bloom and the solutions for the majority of flower friends to refer and learn. First, the reason why orchids do not bloom. 1. The plants of orchids are still small and do not have reproductive genes. Some young seedlings that have not yet formed pseudobulbs can bloom only after two years of vegetative growth to form pseudobulbs, and then germinate new shoots two or three times, and the branches are three generations 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, less leaves per plant, less ash accumulation of organic matter and no active reproductive genes. Generally speaking, it is difficult to blossom without three generations of pseudo-bulbs in the same house. 3. Improper dry and wet, spring and summer and autumn are the vegetative growth periods of orchids (but need to avoid plum rain and torrential rain). If autumn is too thousand, it will make vegetative growth. Winter is its dormant period, which should be on the dry side. If it is too wet, it is easy to make the basin soil freeze and expand, squeeze the roots, affect the new shoots of the following spring and summer, and affect its normal reproductive growth. 4. The light is too little, and the accumulation of organic matter is limited, which can not supply the needs of reproductive growth. Although Lanhuo is a shady flower, it does not mean that it does not need time. It only avoids direct and long light. But need to diffuse, scattered light (semi-shade). Plants that tend to grow in the shade have dark green leaves, but they are more difficult and less flowering, while those growing in the south and mid-summer shade are slightly yellowish-green, but with more flowers, and are gaudy and fragrant. 5. Orchids do not blossom because of their own special characteristics. You should know that very few orchids do not like to blossom. This phenomenon has occurred in various orchid species. Before the solution, it was written in the book that more yang means more flowers, and more yin means better leaves. This shows that if you want the orchid to blossom more, it is necessary to let the orchid bask in the sun. Basking in the sun more is beneficial to the orchid to accumulate the nutrients of flowering, and basking in the sun in the bud is beneficial to the orchid to produce a better opening product. Secondly, the amount of watering is also the main condition for orchid flowering, and the moisture should be well controlled. If there is too much water, the orchid plant will grow and it is not easy to grow buds. Proper moisture is one of the ways to promote flowering. However, when there is a lack of water, the phenomenon of clamping will occur. To promote orchid blossom again, it is necessary to make the temperature difference between day and night about 10 degrees Celsius, that is, the temperature of 18 to 21 degrees Celsius during the day and 7 to 10 degrees Celsius at night grows best and blossoms more. When the temperature is high at night, the leaves of the orchid plant will be soft and the flower buds will fall off. Too low temperature can cause blind buds and spots on the leaves. The flowers show brown spots when they are damaged by low temperature when they bloom. Usually maintenance of orchids should also maintain a ventilated environment, too muggy, will also lead to not blooming. Conclusion: the above is the analysis of the reasons why orchids do not bloom. I hope you can exchange more knowledge about orchid planting.
