Pests Eating my Irises
My irises have small chew holes in their leaves. I thought it was too soon for caterpillars, and I am worried about my budding bulbs. How do I organically get rid of the pest chomping on my irises?

Have you seen the insects that are chewing holes in the leaves? If they are indeed caterpillars, Bt (Bacillus thuringiensis) is a natural insecticide that would control them. Spinosad is another natural product that has broad insecticidal activity. Another organic approach is to physically remove (hand-pick) and destroy the chewing insects.
