Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly when the top 2-3 cm of soil feels dry. Cestrum diurnum prefers consistently moist soil but dislikes waterlogging. Reduce watering slightly in winter when growth slows.
Ensure good drainage to prevent root rot, especially in containers.
Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches.
Heavy pruning can be done in late winter or early spring before new growth begins to stimulate more vigorous flowering.
Propagate by semi-hardwood cuttings taken in summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil consistently moist and humid. Cuttings typically root within 4-6 weeks.
Repot every 2-3 years in spring, or when the plant becomes root-bound. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.
