Melaleuca alternifolia prefers consistent moisture, especially when young. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly in winter but never allow the soil to dry out completely.

Avoid waterlogged conditions, which can lead to root rot.

Prune to shape and maintain size, typically in late spring after flowering. Remove any dead, damaged, or crossing branches. Light pruning encourages bushier growth.

Heavier pruning can be done to rejuvenate old plants, but do so gradually over a couple of years.

Best propagated from semi-hardwood cuttings taken in summer or autumn. Dip cuttings in rooting hormone and plant in a well-draining, moist medium. Maintain high humidity and warmth.

Seeds can also be sown in spring, but germination can be erratic.

Repot young plants every 1-2 years, or when root-bound, in spring. Use a well-draining potting mix. For mature plants, repot every 3-4 years or top-dress the soil annually.

Choose a pot only slightly larger than the previous one.
