2, plastic, binding, do a good job of pruning and thinning buds.
3, lack of anti-fertilizer, crab claw orchids like warmth, after flowering, you can cut 3 to 4 stems under the residual flowers to facilitate ventilation. At this stage, the fertilizer-deficient buds are thin and easy to fall off, and they are moist and semi-shaded. After flowering, it will enter a dormant period of nearly one month. Unless it is particularly dry, there is no need to water it. The temperature should be kept above 10 degrees, below 5 degrees or the temperature difference should be around 10 degrees, which will cause serious bud drop.
4. Pot soil should be kept slightly dry. Indoor air-drying, you can water with fine eyes, and often spray water on the leaves to prevent cold and excessive temperature difference. Excessive humidity can easily lead to root rot. Water the new buds after germination, and topdressing 500 times of potassium dihydrogen phosphate outside the roots every 10 day. If you water the flowers with tap water for a long time, you can add 1000 times of ferrous sulfate to the liquid fertilizer in combination with fertilization. You can put it in a sunny place in winter.
5. Prevent excessive humidity. Crab claw orchid is grafted with succulent flowers such as cactus, which is transparent. In order to control the plant type is too large, pruning and shaping can be carried out by changing pots in spring.
The crown diameter of crab claw orchid can reach 60 ~ 100 cm, and it can bloom 200 ~ 300 flowers at the same time, with beautiful shape. Especially in the dead of winter, the outdoor flowers and plants are dying, but the crab claw orchid is full of flowers and vitality. The thick green leaflike stems are particularly beautiful against the colorful flowers. But it is not easy to make it colorful every year. In addition to the usual careful cultivation, the maintenance and management before and after flowering is particularly important.
After the autumn is cool, the crab claw orchid can get pregnant and enter the flowering period. At this time, move the indoor flowers to a sunny place to avoid damaging the buds due to the large temperature difference between day and night. At the same time, we should trim the flower shape, cut off the uneven stem and hang too many weak buds on the main stem. Don't force it. It is necessary to do so. 1. After pruning, the shape of the plant is symmetrical, and it keeps an umbrella shape to achieve the purpose of beauty. Second, remove the weak and redundant buds, so that the whole flowering period will grow vigorously and the flowers will be the same size. Otherwise, the buds at the top stem nodes will wither due to insufficient nutrition.
Granular compound fertilizer can be applied once every 10 day at flowering stage. Bury in the soil along the edge of the basin, not near the root, so as not to burn. When the soil is wet, it can be dried. If you do a good job of maintenance and management before flowering, you will see a beautiful and spectacular crab claw orchid in winter and early spring next year.
From the end of February to the beginning of March next year, the flowering potential of the crab claw orchid will gradually weaken or even end. At this time, the crab claw orchid is about to enter the dormant period. Most of the stems originally hanging flowers are soft and wrinkled, and some still have some residual flowers, but they should all be cut off, and attention should be paid to trimming the flower shape. Before and after the vernal equinox, put flowers on the balcony or window to shelter from the rain and keep the soil dry. Often spray some water mist on plants to make the branches bright. After the dormancy period is over, the new buds germinate, so you can fertilize and water normally.
