This morning, I found SCALE on my Sans!It's a cultivar from my mom that she's had more than 30 yrs. I've owned this baby for 9 yrs and have NEVER seen this. I fear that the scale arrived on a new Drac cordyline I just purchased.

I've banned the DC to another room and will attack the scale by picking,after misting with a 1/3 water, palmolive dish soap and oil adding a bit of alcohol. Then I'll wipe down each gloriously tall leaf w/ cotton ball and alcohol.

Thank you all very much for the great posts. I was really at a loss...
