Question From: Wenatchee, Washington, United States
Q: My trumpet vine has flowered all summer, now that fall has begun, all of the apical tips have died back to the first bracket of leaves. There are no flowers left at all. Additionally, the nearest remaining leaves have developed odd deformities, including multiple tips and something akin to blisters. This happened seemingly overnight, certainly in less than a week. The weather has been in the 70-80 degree range during the day and cooling to the high 40s-50s at night. It is planted in sandy soil and watered weekly. I live in the arid region of Eastern Washington.
Sounds like some sort of disease. I suggest you bag up some cuttings of infected leaves showing the symptoms and take them to an independent garden center or nursery that sells shrubs for an accurate diagnosis and method of control. Best And Happy Yardening, Nancy
