Orchids in the glass

If you just want to put the orchid in a new glass jar, only a few preparations are necessary. However, the change from soil to substrate-free cultivation looks different. For this you need:
  • glass vessel
  • scissors
  • water
Similar to a hydroponic plantation, the transition from conventional potting soil poses some difficulties. Because the roots of the plants must be cleaned completely from the old substrate. Even the smallest of remnants can lead to the formation of decay at the increased humidity in the glass vessel, which ultimately weakens the orchid sustainably and can lead to its death. Follow these steps:
  • Gently clean the roots mechanically.
  • Put the root system in the lukewarm water.
  • Carefully move back and forth.
  • If necessary, clean it again with a soft brush.
Under no circumstances should the aerial roots of the orchid be damaged during this procedure. Therefore, be as careful as possible. With the scissors weak, injured or dead roots are shortened. The rule is: less is more. Because in the end there should be enough healthy root system. If this is not guaranteed, leave the plant untouched. Especially healthy orchids quickly get used to the change and can regenerate themselves.
Other room orchids can be planted in the glass, but it needs constant humidity. For storage, you can resort to an air-permeable substrate, such as a mixture of Styrofoam, bark and peat. But also seramis and expanded clay have proven themselves.

The ideal location

The tropical ornamental plants are extremely light-requiring, but do not tolerate strong midday sun. Window sills on the east or west side, on the other hand, are very well suited to meet the lighting needs of tropical orchids. In winter, direct proximity to active radiators leads to irreparable leaf damage. But even cold from below can have a negative impact on the health and resilience of Orchidaceae. Here, a 2 to 3 cm thick pad of styrofoam can help.
In summer you can treat the ornamental plants in the decorative plant containers also an outdoor stay. For example, conjure up a tropical floral atmosphere at your next convivial garden party or create a personal oasis of wellbeing on the terrace. Regardless of where you place the orchid, keep in mind the following points:
  • Avoid direct and long-lasting sunlight.
  • Avoid dark locations.
  • Protect from wind and rain.
  • Safe from rodents.
All orchid plants are extremely sensitive to standing wetness. In free-growing Orchidaceae rainwater can bead off or seep directly into the loose soil. In glass vessels, however, the roots are exposed to the ever-increasing water level defenseless and can suffer damage resulting from decay. Even diseases and pests have an easy game with the weakened plants. Even regular pouring is not enough. As a precaution, you should therefore place orchids outdoors in a covered area.

Pouring and fertilizing

Orchids in the glass

Each type of orchid places different demands on the right supply of water and nutrients. In Vanda hybrids, it is sufficient if you put the orchids in a water bath about every 4 to 5 days to the upper root neck. The immersion bath can be done directly in the glass container and should last a maximum of a few minutes. Tilt the water directly afterwards completely. Because waterlogging is not tolerated by the robust hybrids. The plants "consume" the residual moisture and roots in the time until the next dive.
Phalaenopsis likes to fall back on a constant supply of water, but without the plant itself comes into contact with it. The pebbles in the glass ensure that the orchid keeps a dry foot, the water is absorbed by the high humidity inside the glass. Again, when watering, make sure that the water level in the vessel does not touch the roots of the plant.
Tip: Spray the leaves of the orchids regularly with a fine water atomizer. Especially in warm locations you protect the plants from overheating.
Although all orchid plants differ in terms of care, you can still refer to the following tips:
  • Bulb orchids should be almost dry before the next watering.
  • Use only lime-free water at room temperature.
  • Distilled water also benefits the plants.
Access a special fertilizer for orchids.This contains all the important minerals that promotes the flowering power and also the resistance of tropical plants. When and how often fertilization is also dependent on the selected orchid species. The fertilizer is administered directly via the irrigation water.
Cultivating the tropical ornamental plants in the glass without soil is not a modern way of planting. Rather, in this way you fulfill the requirements of many orchid varieties whose roots depend on light. In addition to the choice of the ideal glass vessel, however, the location and the proper care contribute to the well-being of the exotic flowering plants. Keeping orchids successful is not only reserved for experienced hobby gardeners, but you should never take the claims of the plants lightly.
