I havee a honeysuckle, also, and despite their reputation as being prolific and disease-resistant, and hard to kill, etc. each year mine, in a large wood container (h 3 ft, w 3.5 ft, depth 2.5 ft), each
spring and summer i have problems with it, usually mildew which has to be treated with a sprayed on sulfur solution, a common fungicide. This year it's got I dunno what on the
growing tips, and buds: little green/purple bugs maybe. Perhaps a spraying with the hose and then maybe insecticidal soap.
