Detailed Guide to Growing Phalaenopsis in Water Culture and Key Care Points

Phalaenopsis is a perennial epiphytic orchid of the genus Phalaenopsis in the orchid family. Its scientific name means "orchid resembling a butterfly" in Greek. It is native to subtropical rainforest regions. In cultivation, it is mostly planted in sphagnum moss, but some flower enthusiasts have tried water culture for Phalaenopsis and achieved good results. Let's take a look at how to grow Phalaenopsis in water culture!

Container Selection

The operation time for water culture of Phalaenopsis is generally chosen in April to May (the beginning of the growing season, when plants acclimate quickly). Rinse the potting medium off the Phalaenopsis roots with water, remove dead and rotten roots. If conditions allow, flower enthusiasts can soak the plant in a fungicide solution, then air-dry the plant in a cool shaded place. Choose a suitable container; a transparent glass bottle is recommended, as you can observe the root condition at any time. Light exposure is beneficial to root growth, and the roots are also a kind of beauty.

Fixing the Plant

Place the dried plant into the prepared container. At this point, you may encounter the problem that the plant cannot be fixed in place. If the plant and container happen to fit well, you can just let the Phalaenopsis leaves support it without any additional fixing measures. You can also choose a suitable planting basket to use with the container. You can also use wire of appropriate thickness to form a ring, wrap it around the roots up to the stem of the Phalaenopsis, and hook it onto the rim of the container. The specific wrapping method depends on personal aesthetics.

Adding Water to the Container

After adjusting the Phalaenopsis and container, you need to add water, mainly for evaporation to provide humidity. The water level should be such that it does not touch the roots, or only slightly touches the root tips. Then maintain the humidity for the Phalaenopsis according to the ambient temperature, and mist it with water. Next comes a long waiting period. The acclimation period varies depending on the original condition of the plant. Generally, signs of new roots and new leaves will appear in 2 to 4 weeks. If they haven't appeared but the plant hasn't died, then just wait a bit longer.

Care and Management

1. Temperature: When the temperature is low in winter, note that humidity should be lower. This is mainly because if the roots have already grown into the water, the roots soaking in water at low temperatures are prone to rotting.

2. Fertilizing: Liquid fertilizer can be sprayed on the leaves. Solid granular fertilizer (such as Magamp) can be placed directly in the water in the container, or wrapped in a fertilizer packet and tied to the roots.

3. Cleaning: After a long period of water culture, moss will grow on the surface of the container and on the water roots. After adding fertilizer, it grows even faster. It needs to be cleaned regularly, otherwise the water roots will rot.

4. Flower spikes: Fixing the flower spikes of water-cultured Phalaenopsis is a problem. Actually, whether to prop them up or tie them is entirely up to personal aesthetics.
