The optimal period for propagating winged elm is early autumn, utilizing stem cuttings. This timing takes advantage of cooler temperatures and adequate light, facilitating root development before winter. Autumn propagation aligns with winged elm's natural growth cycle, ensuring higher success rates and healthier growth in spring.

Once rooted, gradually acclimatize the winged elm to less humid conditions by opening the plastic covering progressively over a week. Once the cutting has established roots, transfer it to a larger pot or outdoor location, providing it with well-draining soil and full sun to partial shade. Water it regularly during dry periods and apply a balanced fertilizer during the growing season. Pruning should be done judiciously to maintain shape and promote a strong structure, especially in young winged elm. Monitor for pests and diseases, and treat them as necessary to keep your winged elm healthy.
