Mold

[HW]

Hi all,

My baby oncidium: Aloha Sunshine 'Blackhole' Maddie Gulbrandson X Kaala (bumble-bee type dancing lady) has some fungus growing on the sphagnum moss when I first acquired it.

I removed the infested moss, soaked the roots in 3% hydrogen peroxide, bleached the pot and repotted in fresh bark mix. A few days later, the mold came back and it came through the drain holes! This suggests the mold was all through the root system.

I have been pouring hydrogen peroxide and sprinkling cinammon powder on the plant everytime the mold comes back for the last few weeks now. The plant is obviously not very happy with me, some of the leaves have turned yellow with brown/black spots and fell off.

Does anyone have any suggestions for getting rid of the mold permanently ? There's been 2 new roots growing since I potted in the bark mix, phew! It's not dead yet, but how would I speed up the plant's recovery from the disease and the harsh treatment I had put it thorough?

Regards,
HW
