When will the latest crab claw orchid blossom?

Crab claw orchid is an epiphytic succulent plant belonging to the genus Crab claw orchid of the cactus family. It is native to the Brazilian tropical rain forest. Because it often grows on large trunks or dark and humid stone crevices in its place of origin, it needs shade and humid environmental conditions for its growth and development. It belongs to short-day plants and requires 8 to 10 hours of sunshine every day. Let's take a look at when Crab claw orchid blooms!

When does the crab claw orchid bloom?

According to the flowering time, the crab claw orchid is divided into early, middle and late species. The flowering time is from September to April of the next year. The flower is single on the top of the branch, rose red, and the flowering time varies according to the region. However, due to the breeding method, some crab claw orchids are regulated to bloom in October. In Japan, Germany, the United States and other countries, crab claw orchid has been large-scale production, become one of the main winter indoor pot flowers.

How to adjust the flowering period of crab claw orchid?

In order to make it bloom early, it must be treated with 8~10 hours of sunshine every day, complete darkness in the rest of the time, and appropriate water control. After taking the above measures, it can bloom in 60~70 days. If it is required to bloom on National Day, it can be treated with opaque black cloth cover or black plastic cover in the middle and late July. It can only see light for 8 hours every day, and cover the black cloth cover for the rest of the time. In this way, it can bloom in late September. During the shading treatment, water is poured once a day to keep the pot soil slightly moist and pay attention to ventilation. In order to prolong the flowering period, it should be placed at about 15℃ after flowering. To delay flowering, pot plants can be maintained at a low temperature of 5~8℃ or extended to more than 14 hours per day.

Why doesn't the crab claw orchid bloom?

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

2. Room temperature is not suitable: when the room temperature is too low, the crab claw orchid that has been pregnant bud is difficult to bloom. At this time, the flowerpot can be moved to the greenhouse to keep the temperature above 15℃, and then moved back to the original room for viewing after flowering.

3, temperature difference is too large: when the temperature difference between day and night is too large, the pregnant buds will be damaged or bud drop, for this reason, from mid-October to mid-November, people should move indoors in time to avoid sudden temperature change, usually in the daytime in the outdoor sunshine, promote more pregnant buds, night into the room to prevent excessive temperature difference.

What if the crab claw orchid doesn't bloom?

1, less nitrogen fertilizer: crab claw orchid does not bloom to apply less nitrogen fertilizer, containing more nitrogen fertilizer, such as horseshoe tablets, ammonium sulfate, etc., although essential for the normal growth of crab claws, but if too much is applied, and in the case of insufficient phosphorus and potassium supply, it will make nutrient growth too vigorous and inhibit reproductive growth. Therefore, nitrogen fertilizer should be applied less.

2, correct light: crab claw orchid is a typical short-day plant, to be in the short day long light conditions to bloom smoothly, some growers love to put it in the winter near the light, due to the extension of the light time, flower bud differentiation is affected, so do not love flowering. The correct way to manage them is to put them where light is in sync with nature, where there is light during the day and darkness at night.

3. Suitable temperature: The flower bud development of crab claw orchid 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. Maintain an ambient temperature of 15 to 20 ° C to ensure normal flower bud development.

4. Pruning old plants: The buds of crab claw orchid are born at the top of leafy stems, so promoting the growth of a large number of new leafy stems is the key to ensuring normal flowering of plants. Every spring, it is best to combine with pot change to cut off part of the older crab claw fleshy stem, and carefully knock the plant out of the pot, use a sharp knife to rotate a layer of old roots on the surface of the soil to promote new roots, so that the plant absorption fertility increases, the growth potential is stronger, and the flowers naturally bloom more.
