In spring, you can put the orchid on the window sill facing south or in a bright light, which can keep the leaves green and glossy, which is conducive to its flowering. When watering, see wet and dry, and pay attention to prevent water accumulation in the basin. In addition, young plants can generally change pots once a year in spring, when changing pots, some old roots should be cut off. The young plant should be plucked early, so as to promote branching, and timely set up a scaffold, so that it can climb up and grow.
Bulblets like the environment of astigmatism and half shade. In summer, sunshade work shall be done well, and the bulb orchid shall be moved to a cool place to avoid exposure to the sun or direct sunlight, otherwise the leaves will easily turn yellow and shrink, and at the same time, the duration of 2-3 hours of astigmatism shall be maintained to provide bulb orchid. In addition, the summer watering must be sufficient, can often spray on the leaves, maintain a higher air humidity, promote the better growth of the orchid.
If more P and K fertilizer is applied, liquid fertilizer with a little more P can be applied properly before the buds bloom, for example, 0.1% solution of potassium dihydrogen phosphate can promote the opening of autumn flowers. In addition, ensure enough light for 3-4 hours a day to promote flowering. Pay attention to keep basin soil moist during flowering. In this case, you can't move the flowerpot at will, because this kind of behavior is easy to cause the flower buds to fall.
The suitable temperature for growth is about 15 ℃ - 25 ℃. In winter, the room temperature should be kept above 10 ℃, once it is lower than 5 ℃, bulblets will be easily damaged by cold, and then the leaves will fall off. In serious cases, the plants will not survive.
