When do crab claw orchids blossom?

Crab claw orchid is an epiphytic succulent plant of the cactus family. It is native to the Brazilian rainforest. Because it is often attached to large tree trunks or dark and moist stone crevices in its place of origin, it needs shady and moist environmental conditions for its growth and development. It is a short-day plant that needs 8 to 10 hours of sunshine every day. Let's take a look at when the crab claw orchid will bloom.

When do crab claw orchids blossom?

According to the morning and evening of flowering, crab claw orchid can be divided into early species, mesophytic species and late species, the flowering period is from September to April of the following year, the flower is single on the top of the branch, rose red, and it will be different according to the region, but because of the way of culture, some crab claw orchids are regulated to bloom in October. Crab claw orchid has been produced on a large scale in Japan, Germany, the United States and other countries, and has become one of the main indoor potted flowers in winter.

How to adjust the florescence of crab claw orchid?

If the crab claw orchid wants to blossom early, it must be exposed to 8-10 hours of sunshine every day, the rest of the time is completely dark, and the water is properly controlled. It can blossom in 60-70 days after taking the above measures. If it is required to blossom on National Day, the crab claw orchid can be shaded with an opaque black cloth cover or black plastic cover in mid-late July. The crab claw orchid is shaded for only 8 hours a day, and the rest of the time is covered with a black cloth cover, so that it can blossom in late September. Water once a day during shading treatment, keep the basin soil slightly moist, and pay attention to ventilation. In order to prolong the flowering period of crab claw orchid, it should be placed at about 15 ℃ after flowering. To delay flowering, the pot plants can be maintained at a low temperature of 5: 8 ℃ or the light can be extended to more than 14 hours a day.

Why don't crab claw orchids blossom?

1, the light is too long: crab claw orchid is a short-day plant, when the light is more than 10-12 hours a day, it is difficult to form buds. If there is plenty of light during the day and strong electric light at night, it will also affect the blooming of pregnant buds.

2. The room temperature is not suitable: when the room temperature is too low, it is difficult for the crab claw orchid to blossom. At this time, the flowerpot can be moved to the greenhouse to keep the temperature above 15 ℃, and then move back to the original room to watch after flowering.

3, the temperature difference is too large: when the temperature difference between day and night is too large, the pregnant buds will be damaged or falling buds, so people should move indoors in time to avoid sudden temperature changes from mid-October to mid-November, and usually bask in more sunshine outdoors during the day to promote more pregnant buds. Enter the room at night to prevent excessive temperature difference.

What if the crab claw orchid does not bloom?

1. Apply less nitrogen fertilizer: if the crab claw orchid does not bloom, it should apply less nitrogen fertilizer and contain more nitrogen fertilizer, such as horseshoe slices, ammonium sulfate, etc., although it is essential for the normal growth of crab claws, if it is applied too much, and in the case of insufficient supply of phosphorus and potassium fertilizer, it will make the vegetative growth too exuberant and inhibit reproductive growth, and then there will be a situation that you do not like flowering. Therefore, less nitrogen fertilizer should be applied.

2. correct lighting: crab claw orchid is a typical short-day plant, which can blossom smoothly only under the condition of short day and long daylight. Some growers like to put it near the light at night in winter, because the light time is prolonged, the differentiation of flower buds is affected, so they don't like to bloom. The correct way to manage them is to put them where the light is synchronized with nature, that is, where there is light during the day and dark at night.

3. The suitable temperature: the flower bud of Cymbidium is slow in the low temperature environment of about 15 ℃, which is easy to cause the dumb bud phenomenon of flower bud death. In addition, if the ambient temperature drops to about 0 ℃, the buds will freeze and die. Keep the ambient temperature of 15 to 20 ℃ to ensure the normal development of flower buds.

4. Pruning the old plant: the flower buds of crab claw orchid grow at the top of the leafy stem, so promoting the growth of a large number of new leafy stems is the key to ensure the normal flowering of the plant. Every spring, it is best to cut off part of the older crab claw fleshy stem in combination with changing pots, and carefully knock out the plant from the flowerpot, and use a sharp knife to remove a layer of old root from the surface of the soil block to promote the new root, so that the plant's fertility is increased and the growth potential is stronger. Naturally, there are more flowers.
