The Norfolk pine (Araucaria heterophylla) is native to Norfolk Island in the South Pacific. In its native habitat the tree can grow to a height of 200 feet. In its hardiness zones in the United States (USDA zones 10 and 11) the Norfolk pine generally remains between 50 and 100 feet tall. Although the Norfolk pine is a conifer, it is not a pine tree. It is a member of the Araucaria genus, which includes the monkey puzzle tree. The Norfolk pine requires warm temperatures to survive and is grown as a houseplant in cooler regions. It is low-maintenance tree, given the proper environmental conditions. It tolerates a variety of soil textures and will thrive even in acid soil.
Choose a planting location in an area that receives full sun. Remember that the tree will get tall, so check for overhead power lines or other obstructions. The Norfolk pine has a weak root system, so any underground structures should be fine.
Loosen the soil in the planting area by digging to a depth of 8 to 12 inches. Use a shovel to crush any large clumps of soil. Rake the area smooth.
Measure the nursery pot in which the Norfolk pine is growing.
Dig a planting hole three times the diameter and the same depth as the nursery pot.
Remove the Norfolk pine from the pot and place the roots into the hole. Throw a shovelful of soil over the roots and work it around the roots with your fingers. Fill the hole with soil.
Water the Norfolk pine until the soil is saturated. The soil may settle when the water drains. If this occurs, add more soil.
