Because the center of the lignified old branches of Prynne is soft cotton wool, it is easy to absorb water and infect bacteria and rot, and the water at the incision keeps seeping downwards, so the infected branches die step by step. Therefore, the pruning operation must be careful. First, cut it diagonally, and trim it flat. Secondly, it should be tied tightly with plastic paper and isolated from the outside world.

cultivation techniques
decrease
Before entering the room, remove dead branches, diseased branches, overgrown proud branches and over-dense branches to minimize the nutrient consumption of plants; When you leave the room, you can properly remove the old leaves under the branches, which is conducive to promoting the growth of new branches. In addition, we should pay attention to harmful buds such as aphids and be sure to prevent them in time.
land
Family potted orchids should be planted in loose, breathable and humus-rich soil. Usually choose a tile basin with good air permeability, a purple sand basin (cylinder) or a plastic basin with many bottom holes. It is best to have a certain amount of granular soil in the basin to facilitate water seepage and ventilation.
Change the pot
According to the crown size and tree age of the white orchid, change the pots and pans with appropriate size to facilitate the vigorous growth of the plants. When operating, wait until the soil in the basin is slightly dry, slowly (or upside down) tilt the basin (cylinder), hold the basin in one hand and the plant in the other, pour out the white orchid and move it into a new basin. The new basin (cylinder) should be padded with a small amount of loose soil in advance, and then watered to make it permeable and planted stably.
illuminate
From March to April every year, the pots and pans planted with white orchids are moved out of the house and placed in sunny places. When the temperature is high in summer, we should choose a sunshade net or build a simple shade shed as appropriate, so that the white orchid can not only bask in the morning sun, but also avoid the bright light in the summer afternoon (to avoid burning branches and leaves due to exposure).
Before and after the long summer, it should be moved outdoors and placed in a sunny and ventilated place with sunshine for more than 6 hours. Only when there is enough light can it grow well, and when there is insufficient light, it will grow white branches and leaves, and it will bloom less or even not. In hot summer, the intensity of sunlight should be slightly shaded to avoid the scorching sun burning leaves and tender stems.
Fertilize soil or land
In the vigorous growth period of white orchids (usually in May, June or July and August of each year), apply flower fertilizer to white orchids once every half month or a little compound fertilizer of nitrogen, phosphorus and potassium every 20 minutes, with 2 ~ 6g each time.
