Florist Home :: Flower Guides :: Dianthus Disease Problems

There are a number of carnation disease problems. The main ones are described below.

Bacterial spot causes elongated light gray spots on the leaves. The spots have a water-soaked border and later become brown. Remove and burn diseased plants.

Fasciation causes distorted leaves and stunted growth.

Stem rot is also called root rot and causes stem decay just below the soil surface, leading to sudden shoot wilting. Avoid infested soil and destroy infested plants.

Leaf spot causes light brown spots on the leaves. The spots have purplish borders. Spotting is most prevalent on lower leaves but may occur on the stems as well. The tips of the leaves die.

Branch blight, blight, and collar rot are names for the same disease. Symptoms are rotting of leaf bases. Ashy white spots occur on the leaves which may be constricted and twisted.

Fusarium wilt causes yellowing of new growth. The plants are stunted.
