zinnia [Double Zahara Strawberry]

Grow in a fertile, well drained soil in full sun

Deadhead to prolong flowering. Pinch back stems of young plants to encourage branching unless long-stemmed flowers are required

Propagate by seed; resents root disturbance so either sow in situ in late spring after the danger of frost has passed or take care when transplanting from seed sown under cover with heat in early spring

Generally trouble free

May be affected by foot and root rot, grey moulds, fungal leaf spot and powdery mildews
