The Q&A Archives: Red Honeysuckle

Question: Hi - I have a Red Honeysuckle that is not doing so well. I is in an area where I have a butterfly garden (they are all healthy). As much as I baby it, it just keeps turning brown, like it is burnt (it is not in complete full sun; morning to mid day). I don't know what to do. It is just about on it last leg.

Thanks - Lynn

Answer: There is a disease that attacks honeysuckles called leaf blight. Symptoms are commonly seen on young foliage first. Infected areas are initially slightly crinkled or rolled. Veinlets and the tissue around them becomes infected and turns yellow. The affected area later turns brown. Lesions enlarge and coalesce with age. A zone of yellow tissue surrounds the affected area and large veins may remain green while interveinal tissue becomes necrotic. Eventually large areas of the leaf become affected. The tissue becomes brown and dry, causing leaves to curl and twist. Most of the leaves on a shoot may become infected giving the appearance of shoot blight. However, woody tissue is not infected. Premature defoliation occurs with heavily infected leaves. If this sounds familiar, it could be what is affecting your honeysuckle.

It should be in full sunshine, with adequate plant spacing to provide good air flow all around the plant. It's also important to schedule irrigation so foliage dries rapidly.

Mancozeb (Fore) is labeled for control of leaf blight, listed as Herpobasidium blight.

Hope this information is helpful!
