Question From: Whitehall, Michigan, United States
Q: our trumpet vine has rusty trails all over the leaves. Very unsightly. What is causing this?
My guess is you have leaf minors. Take samples of the damage to an independent garden center for an accurage ID and method of control. Timing is crucial. Once they get inside the leaves it's over for the season. Google "life cycle of the leaf minor" for more information. Best And Happy Yardening, Nancy
