Pests and diseases
Listed here is every problem for which the sources name this plant as a host. The problems are not listed in order of how common they are.
Powdery mildew
disease- Signs
- A white, floury coating spreads over the leaves, first on the lower and older ones. The leaf under it yellows and dries up. The fruit stays small, because the plant loses leaf surface.
- Prevention
- Plant resistant varieties, leave an airy spacing and sun, and clear the debris at the end of the season. Unlike most fungi it is not helped by wet foliage, since it spreads in heat and high air humidity, in a dry summer too.
Rose black spot
disease- Signs
- On the leaves there are purple to black spots, with the leaf yellowing around them. The leaves drop early and the bush stands bare by midsummer. The weakened plant flowers less well the following year.
- Prevention
- The fungus overwinters on fallen leaves and in dormant infections on young shoots and buds. In autumn pick up and remove the fallen leaves or bury them under mulch, in winter pick off the leaves that stay on the bush as well, and in spring, before the leaves come out, cut out every spotted part of the shoots. This only delays the start of the disease, because the spores arrive with the rain from elsewhere.
- What to do
- Do not use fungicides. What is left is cleared leaves, cutting out the spotted shoots in spring and the choice of variety. The resistance of a new variety usually does not hold for long, because new strains of the fungus turn up. The old species roses are the least affected.
