Pruning: Promptly remove spent flowers and yellow leaves to encourage branching and a second bloom; pinch off the top when the plant grows too tall.
Overwintering: Annuals wither in winter; for perennials, the aboveground parts wither but the roots can survive the winter, and in the north they need to be covered with film for warmth.
Pest and disease control: Common diseases of Jerusalem artichoke include root rot and leaf spot, mostly caused by poor ventilation and waterlogging. Prevention comes first: keep the environment ventilated and avoid keeping the leaf surface wet for long periods. Main pests include aphids, red spider mites and scale insects; once found, they can be sprayed with the appropriate pesticide.
Repotting: Repot once every 1-2 years, choosing a pot one size larger than the original, replace with fresh potting soil, trim old and rotten roots, then replant. The suitable time for repotting is generally during the spring growth recovery period.
