illuminate
Winter is the flowering period of crab claw orchid. In order to ensure normal flowering, it is necessary to give sufficient light, 8~ 10 hours a day can promote the normal differentiation of flower buds, and the flowerpots are often rotated to make all parts of the plant receive light evenly.
temperature
When the temperature drops in winter, move the crab claw orchid to a sunny place indoors in time to avoid frostbite. The room temperature should be kept at 2 1℃, and the temperature should be appropriately lowered at flowering stage, and controlled at 10~ 15℃. Avoid sudden temperature drop or excessive temperature difference.
water
Crab claw orchids like to be wet, but their roots like to be dry, so water them on the principle of being dry but not wet. In winter, the temperature is low, the water evaporates slowly, and watering should not be too much. Water should be poured every 4~5 days. Avoid water in the basin, which is easy to rot. Water is often sprayed in the bud stage of plants to keep the stems moist.
Fertilize soil or land
In winter, the crab claw orchid is breeding buds and needs sufficient nutrients. In winter, phosphate fertilizer is the main fertilizer, and the decomposed liquid fertilizer is applied after 7~ 10 days. Or spray leaves with potassium dihydrogen phosphate solution to ensure the normal growth of flower buds. In the flowering period, in order to ensure continuous flowering, phosphorus and potassium fertilizer were applied every 10~ 15 days.
decrease
The grafted crab claw orchid grows vigorously. Usually, families will use circular supports to support drooping stems. When plants spread around, they will cut off uneven stems and diseased branches. If the buds are too dense, they can be properly thinned. Leaving a big bud on each stem node and cutting off other buds can reduce the loss of nutrients and make the flowers bloom brightly.
In winter maintenance, crab claw orchids tend to wilt and spend less, so it is necessary to check whether they are properly placed in time to reduce the light.
