Healthy Phlox Plants Are Severed At Base

Question From: Nantucket, Massachusetts, United States
Q: Tall healthy phlox paniculata plants are good and healthy one day and next severed at the base. What is causing this. Slowly all my phlox are being destroyed.

A: If the plants are not eaten, my guess is you have cut worms. Google cut worms them for more info and control measures. Best And Happy Yardening, Nancy
