In the wild, Norfolk Island pines grow in sandy and slightly acidic soil. This means they need well-draining soil, which you can make by combining equal parts:  Potting soil Peat moss Sand These trees like soil that's evenly moist, similar to the slight dampness of a wrung-out sponge, but not wet or soggy. Before watering, stick your finger into the soil. When the top inch (2.5 cm) of the soil is dry, water thoroughly with lukewarm water until the water drains through the holes in the bottom of the pot.  Allow all the excess water to drain through into the saucer below the pot. Empty the saucer when the water stops flowing.  Even if it only happens once, severe drying can cause needles and branches to dry out, fall off, and never grow back. Norfolk Island pines need several hours of sunlight per day, but they do not like direct sunlight. A good location for this plant is in a room with lots of northeast- or northwest-facing windows.  You can also place these trees in rooms with south- or west-facing windows, but they must be shaded windows to protect the tree from direct sun. Other great locations for a Norfolk Island pine include sunrooms and covered patios. In the spring, summer, and early fall, feed the Norfolk Island pine with a balanced fertilizer every two weeks. When the plant needs to be watered, add some liquid fertilizer to the water and feed the tree.  A balanced fertilizer is one with equal parts nitrogen, phosphorous, and potassium. Norfolk Island pines do not need to be fed during dormant periods in late fall and winter. To know when the growing phase starts up again, look for light green growth on the tips of the branches in spring.

Summary:
Plant the tree in the right soil. Keep the soil slightly moist. Make sure the tree gets lots of indirect sunlight. Fertilize during growing phases.
