Reproduction of White willow ( Salix alba ) by means of 1‐ or 2‐year old cuttings is recommended, since these cuttings are not yet infected by Erwinia salicis , the cause of the Watermark disease. The use of sets originating from older trees or pollard willows should cease, since there is no guarantee that they are healthy.
