We have been pulling carrots for a couple of days and have found that about 1/2 have little worms. These small critters are smaller around than a hair and about 1/3 inch long. They are usually near the bottom half.
So how do I treat my soil next year? I'm not into organic and believe that a decent insecticide will save my future crop. In the past I have relied on wood ashes but, no further.
