How to Water Orchids? Master the Key Techniques of Water Management

     Water management for orchids is very important and is one of the keys to success or failure in growing orchids. As stated in "Linghai Lanyan" (Orchid Talks from Lingnan), "There are living methods for growing orchids, but no rigid rules" - water management should be handled even more flexibly.

　　

1. Newly potted orchids must never be immediately drenched with "settling-in water." Transplanted orchid plants inevitably suffer some damage to their roots and rhizomes, making them prone to bacterial infection. If watered immediately after potting, it will affect the normal growth of the orchid plant, causing root rot, withered leaves, or even death. Before transplanting and potting, the orchid roots should be dried slightly so they become somewhat softened and less likely to break. At the same time, the growing medium should be moist but not wet. After planting, if the weather is dry, you can spray a fine mist on the leaves, and it is better to wait three days before watering thoroughly.

　　

2. Orchids should be watered by pouring. Orchids have the habit of "loving cleanliness and fearing filth." Watering by pouring can both satisfy their water needs and flush out residual fertilizers, chemicals, and stale gases from the growing medium in the pot, renewing the air inside the pot so that the root system can better absorb nutrients from the air. If watering is frequently not thorough, causing the growing medium in the pot to be neither dry nor wet ("half-sick water"), it easily leads to the problems of the medium heating up and turning sour, and bacteria and pests multiplying. Therefore, in orchid growing, "half-sick water" is the thing most to be avoided.

　　

3. When encountering "white-blinding rain" (sunshine rain), water heavily. In the hot seasons of summer and autumn, there are times when the sun is shining while it is raining (sunshine rain). This kind of rainwater is extremely harmful to orchid growth and easily causes disease. After such rain, water heavily in a timely manner to wash away the acidity in the rainwater and the stuffy hot gases in the pot.

　　

4. If a large number of disease spots appear on the orchid leaves, be careful not to spray or sprinkle water on the leaf surfaces for the time being. Keep the leaves dry to prevent the spread of pathogens. Only after spraying fungicide to control the disease can you spray water on the leaf surfaces. If the disease is not yet controlled, you can only water thoroughly along the edge of the pot to soak the growing medium.

　　

5. Different water management should be applied according to the seasons. In winter and spring, temperatures are lower and orchids are in their dormant period, with new shoots not yet emerging and the plants requiring less water. If too much water is supplied, it will damage roots and leaves and affect the normal growth of the orchid plant. In summer and autumn, orchid plants sprout and gradually enter their vigorous growth period. Summer and autumn temperatures are high, and the plants absorb and evaporate large amounts of water. Therefore, more water should be supplied to meet the needs of orchid growth and to help prevent heat and lower temperature. Orchid water management can be divided into three steps: "spraying, sprinkling, and pouring." Generally, "in winter and spring, spraying and sprinkling are primary; in summer and autumn, sprinkling and pouring are combined." In hot weather, it should be done in the early morning and evening; in cold weather, it should be done at noon when it is warmer. At the same time, according to the physiological characteristics of orchids, regular spraying and sprinkling to wash away dust and dirt from the leaves is more conducive to the plant's respiration and nutrient absorption, promoting normal growth.

　　

There is no fixed method for orchid water management. It must be determined according to factors such as the orchid pot, growing medium, environment, light, temperature, humidity, ventilation conditions, variety, weather, and the growth condition of the orchid plant. In particular, you need to understand the habits and characteristics of orchids to provide suitable water supply. Orchid enthusiasts should be good at exploring and summarizing in their orchid-growing practice. The approach that achieves success is the most workable method.
