V. Key Care Points

In the daily care of hollyhocks, pay attention to the following points:

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