Knock out roses disease?

Asked June 25, 2013, 4:35 PM EDT

My knock out roses start out beautiful but after first blooms the leaves turn yellow and start falling off. They are bare, but continue to put on some new leaves at the end of the branch and some blooms.

Howdy!
Just got this in my email box, so sorry for the delay.
Is this still a current problem in July? I don't know how long this question has been out there in cyberspace.

First, idea is to have discussion by phone about soil, location, fertility, watering, etc. I am in the office today. Additionally, is this one plant or many?

If we cannot determine anything from that, I would recommend submitting the entire plant to the TAMU Plant Diagnostic & Disease Lab on campus. Their website is: http://aggie-horticulture.tamu.edu/organic/files/2011/03/stinkbugs.pdf

Hope that helps. cd
