How to maintain the bracts of crab claw orchid

During the maintenance period of the flower bud, the crab claw orchid had better be topdressing the mature organic fertilizer for 1 or 2 times, fertilizing mainly along the edge of the pot, not fertilizing after growing buds, keeping a minimum light treatment of about 10 hours a day before flowering, and controlling the temperature at night at about 10 ℃. If there is not enough light during the day, the supplementary light treatment can be carried out at night.

1. Rational fertilization

The fertilization of crab claw orchid is also different in different growth periods, and appropriate nutrients should be given when the bud grows, so it is necessary to supplement potassium dihydrogen phosphate fertilizer to the leaves before flowering. At this time, it is also necessary to apply mature organic fertilizer for 1 or 2 times, mainly along the edge of the basin, and then every 10 days, and then stop fertilizing when the buds grow.

If the sun is not enough during the day, light should be illuminated at night.

3. Temperature control is the main factor affecting the flowering of crab claw orchid. The temperature should be kept at about 10 ℃ at night before flowering. After the flower bud is formed, the temperature can be increased to about 20: 22 ℃. The best temperature during the day is above 22 ℃. The temperature difference caused by this can make the plant blossom ahead of time and promote the formation of flower bud.

4. Rational watering

Watering should be carried out in an appropriate amount in autumn, generally watering when the pot soil is dry, and watering should be timely, otherwise it will affect the growth of flower buds, watering can not be too much before flowering, and watering times can be increased appropriately after flower bud differentiation is completed. it can be carried out according to the principle of a small number of times.
