Gardenias require consistent moisture. Water thoroughly when the top 2-3 cm of soil feels dry, ensuring good drainage. Avoid letting the plant sit in standing water, which can lead to root rot.

Reduce watering frequency slightly during cooler, dormant periods in winter, but never allow the soil to dry out completely. Use soft, room-temperature water if possible.

Prune gardenias after they finish blooming in late summer or early autumn to maintain shape, remove spent flowers, and encourage bushier growth. Remove any dead, diseased, or crossing branches.

Light shaping can be done throughout the year. Avoid heavy pruning in late autumn or winter, as this can remove flower buds for the following season.

Gardenias are commonly propagated by semi-hardwood stem cuttings. Take 10-15 cm cuttings from healthy, non-flowering stems in late spring or early summer.

Dip the cut end in rooting hormone and plant in a well-draining, moist potting mix. Provide high humidity and warmth, typically under a plastic dome or in a propagation chamber, until roots develop.

Repot gardenias every 1-2 years, or when they become root-bound, typically in spring before new growth begins. Choose a pot only one size larger than the current one to avoid overwatering issues.

Use a fresh, acidic, well-draining potting mix. Handle the roots gently to minimize stress. Ensure the new pot has adequate drainage holes.
