Fertilizing

Monthly during growing season (spring and summer)

Pruning

Prune in spring to control size and promote bushiness; remove any leggy stems or dead leaves. Wear gloves as sap may irritate skin.

Propagation

Take 10-15 cm stem tip cuttings in spring or early summer. Remove lower leaves and dip the cut end in rooting hormone. Place in moist perlite or potting mix at 20-25°C with high humidity. Rooting usually occurs in 4-6 weeks.

Growing

Crotons require bright, indirect light to maintain vibrant leaf coloration; direct sun can scorch leaves. Keep soil consistently moist but never waterlogged; allow the top 2 cm to dry slightly between waterings. Use a well-draining, peat-based potting mix and maintain high humidity by misting or using a humidity tray. Fertilize monthly during the growing season with a balanced liquid fertilizer. they are sensitive to cold temperatures; keep above 15°C and avoid drafts.
