How to grow

Cultivation Grow in a sheltered site in full sun in fertile, well-drained soil enriched with organic matter and general-purpose fertiliser. Water freely in dry weather. Pinch out the growing tip when the plants are 15-20cm tall to encourage free-flowering, bushy plants. Staking and deadheading are not usually required. Plants should survive outdoors in most areas especially if protected by a thick mulch. In very cold areas lift the crowns and store in a greenhouse, raising fresh plants from these each year

Propagation Propagate by softwood cuttings taken in spring

How to care

Pruning Cut back to near ground level in the autumn

Pests Aphids and leaf miners are common pests. Leaf and bud eelworms can damage stock that has not been heat-treated. Earwigs sometimes damage blooms. Capsid bug and glasshouse red spider mite are occasional pests

Diseases Chrysanthemum white rust can be very damaging and hard to control. Powdery mildews can be damaging in dry conditions. In wet weather, grey moulds and other fungal rots can be severe. A virus may cause stunting and leaf markings
