Pruning and fertilizing crab claws
The reasons for the different sizes and small amounts of crab claw orchids may be related to factors such as imbalance of fertilization, undernutrition, and low room temperature. For the crab buds that have been flower buds, they should insist on applying a thin fertilizer every 10 days, such as potassium dihydrogen phosphate, the concentration is about 0.2, you can also use multi-component fertilizer; in general, the crab claws of the existing flower buds Blue, the room temperature should be maintained above 10 °C in winter, and slightly light, and the potting soil should be dry, not too much water or often too wet.
The pruning, stalking and tying work of the crab claw orchids are: after the spring flowers, the short cuts from the 3 to 4 pieces of the stems under the residual flowers are promptly removed, and some of the old stems and the dense stem sections are removed to facilitate ventilation. And home maintenance; in the cultivation of crab claw orchid, sometimes four to five new branches will grow from the top of a segment, and one or two should be deleted in time.
There are too many weak flower buds on the stem section, and some should be removed, which can promote the flower size and flowering. The plants cultured for 3 to 5 years can be inserted into the pelvic wall with 3 to 4 thick lead wires. In the soil, the upper part is tied into a 2 to 3 circular bracket, and the branch branches are tied to the ring to avoid the stacking and scattering of the stems, and some uneven stem sections are deleted to make the plants umbrella-shaped. This will be beneficial for photosynthesis and display viewing.
In order to control the plant shape to be too large, it is suitable for indoor decoration. When the whole plant has a diameter of more than 50 cm, the stem section can be shortened in the spring, and some aging and overly dense branches are removed, and the branches are removed. The new branches that grow later will look green and strong, and the flowering will be more lush. It is worth noting that the pruning should be carried out on a sunny day, not on rainy days or in the summer.
The application of crab claw orchid should pay attention to the following aspects: After the flowering of crab claw orchid in March, there is a short period of dormancy, the fertilizer should be stopped and water control, until the sprout is sprouted on the stem section, the normal water and fertilizer management is given; Apply thin nitrogen fertilizer once every half month in the season, do not smear the stem section to facilitate the vegetative growth of metamorphic stems.
Crab claws can be changed every 2 years, usually from March to April, except that sandstones of about 3 cm thick should be padded at the bottom of the basin to facilitate drainage, and should be added to the culture soil. If the temperature is above 30 °C, the plant enters a semi-dormant state when the temperature is above 30 °C.
At this time, not only should we avoid the sun and rain, but also should be placed in a humid and cool place, while stopping the fertilizer to control the water to prevent the roots of the plants; autumn and winter are the flowering period of the buds of the crab claws, in late September. Slightly see the sun, and then give full light in the middle and late October, which can promote flower bud differentiation and multiple buds. At this time, it is better to apply a liquid fertilizer with more phosphorus every 7 to 10 days until the flowering stops.
