Little Lost - Losing Leaves

[kmccormic]

Hi There!

I have 2 dendrobiums. I recently repotted them (and my whole 10-plant collection) 2-3 weeks back, because I thought I might've had bugs in the mix- some plants had bugs, not all. No more sign of bugs. The mix is lecca, small stalite, bark, some charcoal, and lots of small perlite, because that's what I could find locally. They've been losing leaves ever since. I tried watering one more frequently and the other less frequently, still yellowing leaves, and no new leaves developing. I'm not sure if, with the new mix, I'm under/over watering, or if this is potentially a biological cycle thing?

Dendrobium victoriac-reginae x sib
Dendrobium lawesii (red and yellow x red)

Could you tell me if this is their "winter rest" now? I'm in the US, I'm not sure if their time schedule is southern hemisphere. Are they deciduous? Evergreen? Type I? Help! I'm not averse to starting over, but I can't even tell if they're dying or not.

Regards,
Kara
