As long as a plant part on your Dendrobium orchid is still green, it fulfills an important function in the plant metabolism. If green leaves or shoots are removed, this intervention weakens the grape orchid and jeopardizes the next flowering period.

Cut withered grape orchid or not?

At the end of the flowering period, the pseudobulbs are initially without flowers and later without leaves. In this case, please stick to the basic rule. As long as a leafless shoot is still green and vital, there are good prospects for further flowers. Only when a bulb has dried up and has died, cut it off with a clean, sharp knife. The cut is dusted with charcoal ash for disinfection.

Only cut aerial roots in exceptional cases

Air roots are significantly involved in the supply of your dendrobium, so that they are also only cut when they are dead. Since they differ in growth from the herbaceous parts of the plant, it is not always clear whether the roots are still alive or not. A vitality test sheds light on the darkness. That is how it goes:

  • Use a knife to scrape off the upper layer of tissue at an affected aerial root
  • Green tissue indicates activity
  • Brown tissue has died

If you don't want to attack your grape orchid with a knife, spray the aerial roots with soft water. In addition to the strands then turn green or creamy white again, scissors or knives are not used.

Tips

For a Dendrobium nobile to plant its flower buds, it depends on a cool resting phase. From October, the rainforest beauty wants to linger at temperatures between 5 and 12 degrees Celsius. At the same time, it is only rarely poured so that the root ball does not dry out. Without this winter time-out, your grape orchid won't bloom.
