With the improvement of living standards, many flower lovers will cultivate some Crabapple orchids at home. If Crabapple orchids don't bloom, it will be a big eyesore. Many people don't know the reason why Crabapple orchids don't bloom. Generally speaking, it is mainly caused by long light time, inappropriate temperature and improper fertilization. At the same time, we should pay attention to the treatment methods of Crabapple orchids after flowering and the treatment methods of pests and diseases. Only in this way can we cultivate more beautiful and lush Crabapple orchids. First, the reason why the crab claw orchid does not bloom and its treatment methods

1. The illumination time is too long

Because the crab claw orchid is a short-day plant, if the sunshine time is more than 1 ~ 12 hours every day, the roots will not grow nutritionally at this time. It is difficult to form flower buds, and flower buds naturally cannot form, resulting in the loss and consumption of nutrients. Moreover, at night, the electric light can't shine for a long time, which will also affect the flowering of flower buds.

solution: it is best to keep 8-1 hours of light every day, and keep it in a dark and cool place at night, and it is not suitable to be outdoors too much in summer. It is best to keep it in a semi-cloudy and semi-sunny state, and shade it irregularly, and keep good ventilation and ventilation, which is conducive to the formation and germination of flower buds and the flowering.

2. The temperature should not be

In general, the suitable temperature of Crabapple is 2℃~25℃, and the flowering temperature is 15℃ ~ 25℃, and it is best not to exceed 25℃. Because Crabapple is not cold-tolerant, it is best to keep the daily temperature at around 2. If the temperature is too low, it will affect the flower bud formation of Crabapple, and the flower bud will develop slowly, resulting in flowering.

solution: it is best to heat it in winter, which can be placed indoors or in Dapeng in greenhouse, and keep the normal light every day. In summer, if the temperature is too high, move it indoors and put it in a ventilated place.

3. Improper fertilization

Many people don't know why the crab claw orchid doesn't bloom. In fact, fertilizer is the main factor. Because the crab claw orchid likes loose organic fertilizer, the root system is weak and easy to be damaged. If too much nitrogen fertilizer is applied, and both phosphorus fertilizer and potassium fertilizer are in short supply, root development will be inhibited due to vigorous nutrition. Thereby destroying the root tissue system and naturally failing to blossom.

solution: it is best to cultivate crab claw orchid mainly with organic fertilizer, followed by nitrogen, phosphorus and potassium fertilizer, because organic substrate will be beneficial to the growth and development of roots, and less nitrogen fertilizer will be applied. This will keep the balance of nutrition, and it can grow and bloom normally. Second, the treatment method of crab claw orchid after flowering

1. Pruning

Craclaw orchid will enter a dormant period after flowering, and most of the nutrients have been consumed during the growth period. When flowering, the root development is slow and the bud formation is slow, so it will enter a dormant period. Therefore, pruning after flowering is also a very important stage. When the crab claw orchid blooms, the redundant lateral branches can be cut off to avoid the consumption of nutrients, which can concentrate nutrients and be beneficial to the growth of the next flowering.

2. Appropriate temperature

Generally, it is necessary to prepare for the next flowering after the crab claw orchid blooms, and the crab claw orchid will enter the next stage of flowering and growth after flowering. At this time, the stems and buds will re-grow and form, so we must ensure the appropriate temperature, the right amount of water and fertilizer, and the reasonable illumination time every day, which will accelerate the effect of the next flowering.

3. Pot soil disinfection

Crab claw orchids need to be re-treated after flowering. Because the root system will consume a lot of nutrients in the soil when Crab claw orchids are put in the pot, the nutrients in the soil will be reduced after flowering. Because of the great demand for nutrients during the growth period, the pot soil should be disinfected first and then put in the pot again to ensure the normal growth and development of plants. Third, the pests and diseases of crab claw orchid after flowering and their treatment methods

1. Red spider

The most common pest of crab claw orchid after flowering is red spider, which has great harm ability. Mainly attached to the leaf, mainly sucking the nutrients on the leaf, and having strong reproductive ability, it will quickly accelerate the senescence of the leaf and even lead to the death of the plant. It is best to spray omethoate solution irregularly and sterilize it once every two weeks.

2. Scale insects

Scale insects appear more frequently after flowering in crab claw orchids, mainly in white spots, and slowly form a large brown pathogen, mainly on the epidermis of leaves and plants. Its harm is great, which will directly lead to the withering and falling of plants. It is best to remove it with bamboo chips at the initial stage, then rinse it with clear water, and spray it with the emulsifiable solution of iminophosphate when it is serious.

Conclusion: Through the above introduction, I believe everyone has a deep understanding of the flowering of Crab Claw Orchid. In order to avoid it in the process of planting crab claw orchid in the future, it can also cultivate crab claw orchid with leafy green branches.
