As an elegant and unique indoor ornamental plant, Phalaenopsis in hydroponics requires both fun and certain professional knowledge in the maintenance process. Especially in the middle stage of hydroponics, the growth of Phalaenopsis enters a critical stage, and correct watering and fertilization methods are crucial for its healthy growth.
Whether Phalaenopsis in Hydroponics Needs Watering in the Middle Stage
Watering Principle: Different from soil - cultivated Phalaenopsis, the roots of hydroponic Phalaenopsis are directly immersed in water. Therefore, the term "watering" is not accurate. A more accurate term is "changing water". In the middle stage of hydroponics, the roots of Phalaenopsis have adapted to the aquatic environment, but it is still necessary to change the water regularly to keep the water quality clean and ensure sufficient oxygen supply.
Frequency of Changing Water
Initial Stage: In the initial stage of growth, since the roots have not fully adapted to the aquatic environment, it is recommended to change the water every 2 - 3 days to remove harmful substances and microorganisms produced by the roots.
Middle Stage: As the adaptability of the roots increases, the frequency of changing water can be appropriately reduced, but the water quality should still be kept clear. Generally, change the water once a week, or change it in a timely manner when the water quality is found to be turbid.
Precautions for Changing Water
Water Temperature: When changing water, make sure that the temperature of the new water is similar to that of the old water to avoid irritating the roots due to excessive temperature difference.
Water Quality: When using tap water, it is recommended to let it stand for one day in advance to allow the chlorine in the water to evaporate, or use purified water.
Water Level: Keep 1/3 - 1/2 of the roots immersed in water to ensure that the roots can absorb water and avoid respiratory obstruction caused by total immersion.
Fertilization Method for Phalaenopsis in Hydroponics in the Middle Stage
Fertilization Principle: Because the roots of hydroponic Phalaenopsis are directly immersed in water and cannot absorb nutrients through the soil like soil - cultivated plants, it is necessary to supplement nutrients through fertilization. Fertilization should follow the principle of "applying thin fertilizers frequently" to avoid root damage caused by excessive fertilization at one time.
Fertilizer Selection
Liquid Fertilizer: In the middle stage of hydroponic Phalaenopsis, special hydroponic nutrient solution or liquid compound fertilizer can be selected. These fertilizers are rich in nutrient elements such as nitrogen, phosphorus and potassium, which are required for the growth of Phalaenopsis.
Granular Fertilizer: In a specific period, such as one month before flowering, granular fertilizers such as potassium dihydrogen phosphate can be used. Sprinkle them on the edge of the container to allow the roots to absorb them slowly.
Fertilization Frequency and Quantity
Liquid Fertilizer: Apply it once a week, and irrigate it after diluting it according to the proportion in the instructions each time.
Granular Fertilizer: Use it once a month before flowering. The amount of each use is adjusted according to the size of the container and the growth state of Phalaenopsis, generally 5 - 10 grams.
Precautions for Fertilization
Avoiding Excessive Concentration: When fertilizing, make sure that the fertilizer concentration is moderate to avoid burning the roots.
Observing Reactions: After fertilization, closely observe the growth state of Phalaenopsis. If phenomena such as yellowing of leaves and root rot occur, stop fertilization immediately and replace the water with clean water.
Combining with Light: The fertilization effect is closely related to the light conditions. It is necessary to ensure that Phalaenopsis receives sufficient light to promote the absorption and utilization of nutrients.
Watering and fertilization in the middle stage of hydroponic Phalaenopsis are key links in the maintenance process. By mastering the correct methods of changing water and fertilization, a good growth environment can be provided for Phalaenopsis, promoting its healthy growth and flowering.
