White “lines” under camellia leaves



  1. 0 Votes

    I think it’s leaf gall. These lines will rupture and release a whitish mass of spores. These then harden and become brown. To treat this, remove and destroy young galls before the surface on the underside of the leaves turn white and spores are released, or else the disease will be worse next year. Rake up and remove leaves that fall. Also, don’t water the infected leaves when you’re watering the plant. Galls develop more easily in wet or humid conditions.

      I now understand that it is caused by “scale insects” treated by Provado that though expensive at £10 a bottle has a picture of the bugs that do the damage. Further research in a gardening book confirms this. Thanks anyway
