Today I noticed two Knuthianus cuttings had scale. I've had them for nearly five months & both came from the same seller, could they have had scale all along; or is it more likely they've been attacked recently? (the cuttings were moved to a more sunny location in the last month, I'm pretty sure stress triggered the attack; just not sure if the scale was there all along).
So far I've quarantined the cuttings & given them a good ol scrub down. They appear scale free for the moment, but I don't think I'm out of the woods yet.
Looks like I'll be paying close attention to my collection for the next few weeks & hopefully with enough repeated toothbrush action I won't need to resort to spraying...
