Yellowing Leaves

[kmccormic]

Hi There:

As you may recall, I had a bug problem which I took some unfortunate actions to try to address. I rinsed, trimmed roots, and repotted them, tossing two with the worst bugs. Since the repotting, I haven't seen any bugs, but the dendobriums haven't bounced back. It seems like they have shriveled in the canes, and leaves have been slowly turning yellow and dropping off. They were in their own mixes from the vendor, and I didn't have small chip bark or moss to replace it, so I put them into a mix of large bark mixed with medium lecca, small and medium charcoal, and small perlite, and small stalite. Since then, I've watered 2-3 times a week, like I had been and they liked it before the repotting, using some Superthrive rooting hormone in some of the waterings to encourage new roots. Any idea what's wrong? They never lost leaves over the winter.

I have a lawesii and a victoria reginae.
