Non-toxic Treatment For Rosemary Plant With Whiteflies

Question From: Greenville, South Carolina, United States
Q: My mature rosemary plant has whiteflies. Is there an product I can spray it with to kill the white flies and still be able to eat the rosemary? I saw the water spraying 3 x a day for 3 days....

A: A neem oil product that lists the letters OMRI on the label would work. Do read the label and follow the directions. Best And Happy Yardening, Nancy
