How to Repot a Bulbophyllum Orchid

Repotting a Bulbophyllum Orchid – Video Demonstration

RVO is happy to share our step by step video demonstration on how to repot your bulbophyllum (bulbo) orchid. Bulbophyllum orchids never want to completely dry out and most appreciate bright (cattleya type light). Many vendors grow their bulbo in sphag moss as this medium allows them to water less frequently and when shipping the orchid, adds very little weight to the package. However, for the home grower, sphag can cause serious problems including root rot. Growers who grow in the home often enjoy watering their orchids. Watering an orchid growing in sphag before it has almost dried out, can keep your orchid roots from being able to breath. Orchid roots like to have air movement around them to allow gas exchange. RVO recommends growing bulbophyllum orchids in a small and medium orchid bark mixture. The mix you will see in our video below uses the following ingredients:

  • medium coconut husks (soaked and rinsed to remove any salts)
  • medium red wood bark (rinsed)
  • sm. seedling bark (redwood)
  • charcoal chucks (small)
  • Perlight or Sponge Rock (small)
  • pulverized lava rock
  • and in the bottom of the pot – we use medium sized lava rock.

The bark mixture is mixed and soaked for a couple of days. We changed the water a few times during the soaking process to remove any salts that may be present in the coconut husks. Once we were ready to repot, we filled the bark mixture with fresh water again and this time, we only use the medium that actually floats to the top of the bucket. Anything that is water-logged and sinks to the bottom will end up rotting quickly and should be avoided as it holds too much water.

After removing the floating mix, we drain the water from our mix bucket and add in the pulverized lava rock and mix well. With the bublo potting mix now ready, we need to remove the orchid from its original grow pot. (Note: the bulbo used in the video was sent to us bare-root .) To remove a bulbo from a pot, simply follow the following steps: First, submerge the pot in a bucket of water to get the medium in the pot as well as the roots very wet and pliable. (Let your pot and roots soak for 10 minutes) Once ten minutes had passed, removed the pot from the orchid’s root mass, clean away any attached medium still clinging to the roots, and began repotting as shown in the video below.
