Winter goes and spring comes, and everything recovers. Spring is the key period for orchid growth. How to raise orchids well in spring is summarized as follows for reference by orchid friends.
First, the blue room management
First, the ventilation of the blue room should be increased appropriately with the increase of temperature; But for those who haven't changed the pot within a year, hurry up and change the pot. The process of changing pots is also a kind of management, removing rotten roots and leaves, the ramet of this ramet. Orchids need to be cultivated with coarse plant materials with good air permeability and good drainage, and the coarse plant materials are mostly a mixture of perlite, fine pebbles and coarse skins.
Second, fertilization.
During this period, increasing fertilizer supply properly has a great effect on the growth of orchids. However, we should pay attention to implementing the principles of "thin fertilizer and diligent application" and "rather less than more". Fertilization of orchids can be divided into root fertilization and leaf fertilization. It is best to use slow-release fertilizers for root fertilization, such as inorganic fertilizers such as "Haokangduo" and organic fertilizers such as "bone powder phosphate fertilizer" and "orchid organic fertilizer". It is best to choose liquid fertilizer for foliar fertilization, such as "liquid flower treasure" and "multiple roots and multiple buds", to avoid that the solid fertilizer is not fully dissolved and attached to the orchid leaves, resulting in leaf burns. If it is not good for the roots, or if you want to grow more buds, you can choose "multiple roots and multiple buds", dilute them in proportion and then water the roots or spray the leaves. Fertilization is best carried out after watering and leaf drying. Root fertilization is generally once every six months, and foliar fertilizer can be once every five to seven days.
Third, water.
Although the air humidity is relatively high in spring, we should pay attention to watering enough water to strengthen the roots of orchids and keep enough fresh air in the orchid pots. Watering must be thorough every time, to ensure that there is water flowing out from the bottom of the orchid pot, and to wash off the plant substances and air pollutants on the orchid leaves.
The watering time of orchids in spring can be flexibly mastered. The general principle is that the closer the water temperature is to the temperature, the better, and the temperature should be kept above 10 degrees.
The watering interval depends on the plant materials, and the selected plant materials can be once a day or once every two or three days. If the selected plant materials are dense, they can be used once every seven or eight days.
After each watering, it is best to strengthen ventilation and dry the orchid leaves.
Fourth, the prevention and control of pests and diseases.
A year's plan starts with spring. If a thorough prevention can be done during this period, it will have a multiplier effect on the prevention and control of orchid diseases and insect pests throughout the year. Orchid pests and diseases are insects, such as aphids, beetles, red spiders and so on. A genus of fungi, such as carbon maggot and black spot. You can choose "quick killing" in disposable small bottles for killing insects, and "Tobuzin" in bottles made in Japan for sterilization. Make a full spray at different times. Spray thoroughly, not only the leaves and back of orchids, but also the upper and lower parts around the orchid room, orchid racks and orchid pots. On the third day after each spraying, insects, bacteria and residual pesticides must be thoroughly doused with clear water.
