Clematis

Diseases & pests on this plant

• clematis wilt (leaf & stem spot)Calophoma clematidina

  A previously healthy, lush clematis shoot suddenly wilts and collapses from the top down, often just as the flower buds form; leaves blacken; at the base of the wilted stem there are dark lesions and dieback, often near a leaf node or a soil-level wound; large-flowered hybrids are far more prone than species clematis. The roots usually stay alive, so the plant often re-shoots from the base.

• slugs & snailsGastropoda

  Irregular holes with smooth (not jagged) edges eaten from leaves, flowers and soft stems, often starting at the margins; whole seedlings can vanish overnight; tender hostas, lettuces and bedding are stripped; the tell-tale sign is a silvery dried slime trail on leaves, soil and pots. Damage is worst at night and in mild, wet weather.

• two-spotted spider miteTetranychus urticae

  Yellow stippling on upper leaf surface, fine webbing.
