Newbie?? - What is this and how do I treat it??

13 years ago

Hi guys...hope everyone's gardens are bursting! I haven't been on in a while, but mine is going bananas. First full season in and I'm very excited!

So my trumpet vine is sick. I know it's pretty hard to kill these things and I think it's just a leaf disease, but could someone please tell me what this is and how do I treat it? I can't exactly remove all the infected leaves since it's kind of a monster, so I hope that's not the diagnosis!

Many of the leaves are affected. The vine is also dropping a LOT of leaves. Here are the spots:

This is the site - it's kind of hard to tell with the yews in the way, but there are 5 large vines trained up the fence. I'm hoping the answer will be some sort of spray??

I'm sorry if this is a dumb question. I did some googling but didn't find out exactly what to do/what to treat it with and what exactly it was. Thank you in advance. :)

looks like fungal leaf spot that can develop from the humidity in summer and/or lots of rain as well.

When watering don't water the leaves, just the ground to get the roots and you can try a fungal spray as well.

The other possibility could be bacterial leaf spot.

You can take one of the leaves to a local garden center to see if they could ID whether it is bacterial or fungal as the treatment would be different for each.

IMO, typical Cercospora leaf spot (fungal disease) caused by overhead watering or overly wet spring or both.
Nothing major. Check hydrangeas below as well. They are very succeptible to cercospora.

Thanks guys...I'm going to a garden center today so I'll bring a leaf along just to make sure. Do you think it could have been all the rain we got in March? It hasn't been overly wet here since and I haven't watered the trumpet vine at all otherwise. It didn't leaf out until maybe 5 weeks ago, and I started noticing the spots about 2 weeks ago. The hydrangeas below are healthy, no spots. (unlike last year, when we got doused in June and July, they looked horrible.)

Check the undersides of the leaves for insects too.
