Caring for orchids properly without soil - this is how it works

This is how maintenance works without a substrate

If an orchid is majestically perched on a branch or impressively staged in a glass, there is no orchid soil available to supply it with water and nutrients. So that the noble plant does not suffer a deficiency, it now depends on this care program:

  • Spray the leaves and aerial roots daily - morning and evening in summer - with soft water
  • Add liquid orchid fertilizer to the spray water every 3 to 4 weeks during the growth and flowering period

Cultivate an orchid in a glass without a substrate, fill it with lime-free, lukewarm water every 2 to 3 days in summer. The heart of the plant and the leaf axils must not get wet. After 20 to 30 minutes, pour the water out again. Ideally, you take the orchid out of the glass vase to dip it in a bucket. With this variant, the water can drain off well before the queen of flowers takes a seat in her glass vessel again.


The orchid culture without a substrate requires a location with a humidity on a tropical level. Where no orchid soil is available as a water buffer, the aerial roots are permanently threatened by drought. Vanda, Phalaenopsis and their conspecifics are very grateful for a place in the humid and warm bathroom or in an air-conditioned plant display case with at least 80 percent humidity.
