Fertilizing. Feed the plant with a balanced, water-soluble fertilizer every 4 to 6 weeks during the growing season (spring and summer). Reduce feeding in fall and winter when growth slows down.
Norfolk Island Pine is a moderately easy plant to care for. It prefers bright, indirect light and needs regular watering but should not be overwatered. It can suffer if kept too dry or in low light, and may develop brown tips if humidity is too low. Overall, it requires moderate attention to thrive indoors.
