How can orchids avoid yellow leaves? These five points must be done first.
Although orchids are beautiful, they are also difficult to raise in family flowers, mainly because they have high requirements for the growth environment. If flower friends do not have a comprehensive understanding of the growth environment of orchids, it is easy to have rotten roots, yellowing leaves and thin growth in the process of maintenance, so how to avoid yellow leaves in the process of maintenance?
1. Watering
Too much watering leads to stagnant water in the basin, which is a mistake easily made by flower friends. once there is stagnant water in the basin, the roots will not have more breathing and absorption to provide the leaves, and then the leaves will turn yellow. Solution: we should choose a flowerpot with good ventilation and drainage, so that if the pot soil is not dry, it will not be watered, and if it is irrigated, it will be fine.
2. Air drying
Dry air causes orchid leaves yellowing due to lack of water for a long time or often too busy to remember to water orchids, which will also cause orchids lack of water and yellowing leaves.
3. Fertilization
Excessive fertilization will also lead to orchid leaves yellowing, usually in the maintenance process, to achieve thin fertilizer less application, can not apply thick fertilizer, large fertilizer and no mature liquid fertilizer, proper fertilizer orchid will grow well.
4. Lighting
Orchids like semi-overcast environment, early spring and winter can be full sunshine, summer should avoid too strong light to cause leaves yellowing, should be placed in a half-shade well-ventilated environment to maintain. Such as indoor maintenance can not be placed in a place without light. Note that the air is drier in summer and autumn, so it is necessary to spray water to increase the humidity of the air, or you can put a basin of water into it. When you put the whole pot of orchids down, the water can not be flooded to the bottom of the basin, which can also increase the humidity of the air.
5. Diseases and insect pests
Sometimes the leaves of the plant suddenly turn yellow when it is well maintained. If there is a situation, you should carefully observe the leaves in the yellowing part, whether there are insects nibbling away at the leaves, and if so, you should poison the pests in time.
