Here's how to care for Norfolk Island pine during, after holidays [Master Gardener column]
The Norfolk Island pine is a popular gift during the holidays, but many people don’t realise it can live for years with the right care. Often mistaken for a true pine, this plant actually belongs to the same family as the monkey puzzle tree. Native to Norfolk Island in the Pacific, it thrives indoors in cooler climates when given proper attention.
In our climate, Norfolk Island pines should be treated as houseplants. Place them near a bright window, but avoid northern exposure. If kept outdoors, they need some afternoon shade to prevent stress.
Watering is key—check the soil surface and only water when it feels dry. During periods of new growth, fertilise lightly to avoid overfeeding. A common issue is browning or dropping lower branches, usually caused by low humidity or too much fertiliser. Keeping indoor humidity above 50% helps, though this can be tricky in most homes. The plant prefers cooler nights, ideally around 10°F lower than daytime temperatures, with a minimum of 50°F. To prevent a bent trunk, rotate the plant weekly so it grows straight. Repotting is only needed every three or four years, once roots start appearing above the soil. For holiday decorating, use lightweight ornaments and LED lights to avoid heat damage. With these steps, the tree can stay healthy long after the festive season ends.
With proper placement, watering, and occasional repotting, a Norfolk Island pine can thrive indoors for many years. Maintaining the right temperature and humidity levels will help prevent common problems like branch drop or a crooked trunk. This makes it a lasting addition to any home, not just a seasonal decoration.
