Grow Notelaea longifolia in ordinary garden soil. This tree tolerates a variety of soil types and rarely requires fertilizer. Notelaea longifolia grows best in neutral soil ranging from slightly acidic to slightly alkaline. Add powdered limestone to raise the soil pH, and add peat moss to lower the soil pH.
Water Notelaea longifolia with 1 to 2 inches of water per week during the first growing season, allowing the soil to dry out between watering for the best results. This tree also tolerates soil that is always moist and generally does not require special maintenance once it establishes its root system.
