The leaves of my honeysuckle had a greyish white mould on them and have now started to go patchy brown and fall off. Is my plant dying or will it recover?
It sounds like your plant has powdery mildew which is a common problem on honeysuckles as well as many other plants. It makes the plant look unsightly but it’s unlikely to kill it. The problem is often worse when plants are dry at the roots so keep susceptible plants well mulched to help keep moisture in around the roots in dry weather; also tidy away and destroy any fallen diseased leaves especially at the end of the season. There are a number of garden fungicides which will also help control powdery mildew; always read the label before use.
