I have a large scruffy weigela as a border hedge and have built a 2m by 1.5 m trellis, mounted to a raised bed placed in front of the weigela. This is for my Bathsheba. Today doing a prune i noticed that the weigella leaves have multiple brown blotches on the edges of the leaves and some of them are looking like simply autumn leaves, ie brown and withering. Admittedly these leaves are last years and they've just come through winter, so I 'd expect some of them to have deteriorated and eventually die off. But I'm wondering, does weigella have 'Blackspot', is this then likely to be blackspot and therefore contaminate my climber ?
