Hydroponic vs. Soil Culture for Phalaenopsis: Which Is Better? Cultivation Methods and Precautions Explained

The Phalaenopsis (moth orchid) can be called the dream flower of many people; its elegant, graceful bearing after blooming makes it widely loved. In recent years, it has even risen to become one of the popular Lunar New Year flowers. But did you know that besides soil culture, Phalaenopsis can also be grown hydroponically? So what techniques do you need to master in daily care? The following text will focus on how to make Phalaenopsis bloom with unprecedented beauty.

Generally speaking, when caring for Phalaenopsis, whether hydroponic or soil-cultured, as long as the substrate is well maintained, it can be made to bloom. If a flower enthusiast buys a hydroponic Phalaenopsis, what needs to be regularly checked at this time is the water quality, because only a clean, pollution-free environment can let Phalaenopsis grow. At the same time, before each water change, an appropriate amount of nutrient solution can be added; doing so can ensure the Phalaenopsis has sufficient nutrients.

If a flower enthusiast buys a soil-cultured Phalaenopsis, it is recommended to choose a substrate mixed from perlite, coconut husk, and the like, because only this kind of loose, breathable, well-draining soil can let it survive normally, while also reducing root rot caused by retained moisture.

Then in daily management, whether hydroponic or soil-cultured, be careful to give the Phalaenopsis diffused light, and never put it under fierce direct sunlight. When encountering high summer temperatures, appropriately add a shade umbrella over its placement location; when winter comes, pay attention to protecting it from the cold and also make some tools yourself to increase light, such as using a grow light to add light.

Next, regarding water management, for hydroponics there is no such thing as watering; usually you only need to check whether the water level reaches the standard line, and at the same time see whether the water quality is cloudy. If you find many impurities in the water, clean and change the water in time to avoid breeding bacteria. For soil-culture enthusiasts, watering should follow the principle of "water when dry, stop when wet," that is, when you find the soil surface slightly dry, water it. At the same time, if it is relatively dry in autumn, use a sprayer to regularly spray the leaves to increase air humidity, but be careful during operation not to spray water into the leaf center.

Finally, to maintain the basic nutrients of Phalaenopsis, fertilizing is indispensable. In hydroponics, a dedicated hydroponic nutrient solution can be chosen for fertilizing, while in soil culture, orchid-specific fertilizer or compound fertilizer can likewise be chosen for "light fertilizer, frequent application," and note that fertilizing should be stopped at high or low temperatures.
