[SG] Mystery Disease

I NEED HELP!!

    I have several white astilbe that are beginning to die and I can't
explain why. First symptoms where a sudden drooping look and over the
past several days the plant has begun to shrivel up. I thought it was
isolated to only one plant until this evening I have noticed several
others with same problem. Plants were on the verge of blooming (flower
stalks grown and up but not open). The astilbe "Pumila" and pink astilbe
have not been affected. The area has received plenty of water (who
hasn't in the tornado alley of the upper midwest) but also has good
drainage. No otherr planys seem to be affected.

    Also I have been attacked by a green caterpillar on my Columbines.
They have stripped several plants to the bone. They leave small black
specs on the plant. What is it and what can I do? I am not against an
organic solution but with no desire to start a war I am also not against
dropping a nuclear bomb or two. Any suggestions?

    One last bug question. I have hanging baskets with liccorish
(spelling?) as a trailing plant. The ends are being attached and curled
up in a web by something I cannot locate. It also leaves the small black
specs or droppings inside this fine web. What is it and again what can I
use to eliminate them? They have no affect on the viburnum that is in
the same baskets.

    Thanks in advance and thanks for the patience on the basket question
as I realize it is not a shade plant question.
