Hi all, I have some exciting news to share. My oncidium was half dead the last time I posted. I ended up trimming off all, yes ALL, off its roots because they were all dead and there's mold/fungus. I stuck it in a home made humidity chamber (a small plastic cup with a medium cup fitted snuggly over top. Punched holes at top and bottom. Then fit the "capsule" in a large cup with water at the bottom) and left it by the window with ambient light.
2 months went by, I was cleaning the room I picked up the chamber for disposal. To my amazement, there are two new growths coming about!
It's too early to tell, but I think they may be new bulb formation or new leaves. There is still a bit of fungus going on but if the plant is surviving, I am not going to bother getting rid of the fungus for now. I am a little surprised that there is no new roots coming though. I am spraying it with a diluted root growing hormone every now and then. Any comments?
