I don't know if we have "cutworms" where I live or not, but we do have little caterpillars that hatch out of the oak trees around here. They come down out of the trees on thin strands of silk, and proceed to eat.........and eat..........and eat. Most times I don't plant anything until I see that they have hatched. I learned my lesson when I first moved here, planted at my "normal" time (roughly 4 weeks ago), and promptly had everything "cuttoff" at ground level. If I wait for roughly a week after I see them coming down out of the trees they seem to be past the "eat voraciously" stage.
