white dots on leaves of perennials
Many of my perennials (hostas, coral bells, holly hocks, ligualaria, penstemon and snap dragon) suddenly have several leaves covered with white dots that do not rub off. What should I do?

Hmmmmm, white dots? Can you send a picture. There are so many ways white dots could be intrepeted -- hail damage, powdery mildew, holes in the leaves, scarring on the top of the leaf but not on the bottom, etc.
There has been quite a bit of hail in many areas and that would caused damage to lots of plants. If that is the case, you might fertilize lightly, remove any unsightly leaves and wait a couple of weeks for new growth.
Send a picture if you think there is something other than hail that could be causing it. Also, how long has this been a problem, when did you notice it, etc.
