My Suzy is a beauty – but what now??
QI brought a black-eyed Suzy last year that has climbed very well. When should I cut it back? Alan Francis, via email
ABlack-eyed Susan is usually grown as an annual in the UK. It is either raised from seed or bought as a young plant and disposed off in autumn. It is perennial but tender and would be killed by frost if left outdoors over winter.
Black-eyed Susan can be grown as a conservatory plant or as a houseplant. If your plant is outdoors, bring it into a
brightly lit spot indoors. If this isn’t possible, take cuttings and overwinter the young plants indoors ready for planting out early next summer. Cuttings will root easily in well-drained soil.
As for pruning, pinch out the tips of young plants to encourage bushiness. For mature plants, remove weak stems and some of the congested stems at the base, but keep pruning to a minimum.
Black-eyed Susan isn’t winter hardy, so either bring it indoors or take cuttings
