Root maggot in Cauliflower http://xohghi.notlong.com/ 6 June 2008 Root maggot in Cauliflower. My cauliflower were drooping, so I pulled one and found it was infested with root maggots. I pulled all plants and put them in water, and will leave them there for several days. In the area the mulch was raked off, and the bed was rototilled several times, and the mulch replaced. It is too late for a early cauliflower, so I will plant a late crop about the 25 of July. This is my first experience with this pest.
