How to grow

Cultivation

Grow in containers in a peat-free compost with added perlite. When buds appear, feed with a high potassium liquid feed. Perpetual flowering carnations are often grown under glass all year but can be placed outside in summer. Stems will require staking

Propagation

Propagate by cuttings taken from non-flowering stems; early spring is a good time to do this but cuttings can be taken any time from late winter through to late summer
