So I think I spent the majority of my day today repotting Orchids, more specifically Zygopetalum Adelaide Meadows 'Brabum' x Propetalum Mathine 'Elizabeth'; Onc. Heaven Scent 'Redolence'; Blc. Waianae Leopard 'Ching Hua'; & Wils. Pacific Passage 'Peach Cobbler'.
Wow, let me tell you Zygo/Ptpm. was SO root bound but roots weren't so rotted (now I'm in that stage of worrying they're going to suffer from my repot and won't be so perfect). But obviously that's not why I'm here, it's about the Oncidiums of course!
So Wils. wasn't so bad, thanks James for telling me from the get go that I should repot after the flowers die. The spike was still green however while cleaning it off I discovered
a MEALYBUG!!!
tucked into the sheath that surrounded the base of flower petiole. I instantly cut the spike and tossed it in the trash. I've not seen Mealys on any other plant...yet...?? After repotting I sprayed it good with Natria (making sure to get it down into the new growth) and left it outside for the night, same for the other two.
Onc. Heaven Scent was WAY OVERDO for a repot. The media was like dirt and packed around the roots, honestly, I wasn't gentle. The root system seemed pretty big as I cleaned the media away. And it was decent once I could really see it however over 75% of the roots were rotted. I would guess this plant may not have been potted after it was as a seedling. Anywho I downsized the pot according to the roots not the plant, there are no new growths; it had 3 spikes when bought, one in bloom, the 3rd is not dying off, and recently found that two smaller spikes are developing.
So what's my point/question? How near to the base of the pbulbs should the new media be? I suspect I potted a little two deep, not crazy but I'll post pictures tomorrow when I can (forgot to get post-pot pics today).
Thanks for all thoughts and advice/suggestions.
