I'm better at 'dusting' them - or tossing them out. :) I don't do live green plants very well - your 'tangled vines and brown leaves' is the main reason. LOL!
...)...I hear ya...don't do much dustin' myself, but I toss 'em soon as they give me that bad look.
I have pretty good luck with most of them, though...it's easy here, they thrive with minimum effort from me...)
