I don't want to damage any of my plants, but would like to know what is the best way to remove (or not to remove if that's the case) dead/burned/yellowed foliage off some of my tropicalesque plants.

Philodendron has some all yellow leaves, Calla Lily stalks/leaves burned but not dead, new zealand flax dry and some dead leaves, Queen palms still have some yellow dead ends on the fronz (sp) from the bad winter frost. Thanks-- Terra
