Repotting Oncidium -
Transplanting into Hydroponics

Repotting Oncidium?
Transplanting Oncidium into Hydroponics can bring dramatic results. These plants require generous amounts of water during the growing season but their roots will rot if kept too wet. This means frequent waterings (almost every day in the summer) and a potting mix that drains quickly.  With our system Oncidium is a large and diverse family of plants. Some look similar; others look radically different. All are comfortable with Hydroponics.
Here's a healthy Oncidium looking for a new (and bigger) grow pot. Perfect choice to illustrate repotting oncidium into hydroponics.


1.  We always start by rinsing LECA pebbles with clear water to wash away the dust from shipping. Then soak pebbles overnight in a solution of 2-3 TBS of K-L-N Rooting Solution per gallon of water. KLN promotes new root growth while resisting disease. Save soaking solution for watering new transplant later.


2.  Remove grow pot and inspect the roots. As you can see, this plant has lots of healthy roots.


3.  Untangeling roots and removing old potting media can be a project with mature Oncidiums like this one. Chop sticks are the perfect tool for removing imbedded bark chips. Remember, remove everything!


4.  Cut away any rooting or discolored roots. Be aggressive!


5.  Many times we remove almost all of the existing roots. 


6.  Fill bottom of culture pot with pebbles from soaking.


7.  Postion plant toward the back of the culture pot with new growth facing front (notice new growth tip in the center). This gives the plant plenty of room for new growth to mature. Add more pebbles. Tap down pebbles to eliminate air gaps.


8.  Insert Water Gauge into culture pot and set plant in Outer Pot. There's a good looking plant!
