The term "Australian Pine Tree" typically refers to the Casuarina genus, specifically Casuarina equisetifolia, also known as the Australian Pine, Coastal Sheoak, or Ironwood. However, it's important to note that despite the name, it's not a true pine tree, but rather a member of the Casuarinaceae family, which is native to Australia, Southeast Asia, and some Pacific islands. Here's a description and care guide for the Australian Pine:

Description:

Foliage: The Australian Pine tree has thin, needle-like, green to blue-green foliage that somewhat resembles pine needles. The foliage hangs in dense, feathery branches and provides a soft, fine texture.

Bark: The bark is rough and textured, often with a greyish-brown hue.

Size: It can grow tall, reaching heights between 50 to 100 feet (15 to 30 meters) or more, with a slender and upright growth habit. It's often used for landscaping in coastal areas due to its tolerance to salt spray.

Seeds: It produces small, cone-like seed structures containing numerous winged seeds.

Care Guide:

Light: Australian Pine trees prefer full sun exposure. They thrive in direct sunlight and are well-suited for coastal regions due to their tolerance to salt spray.

Temperature: They are adaptable to various temperatures but generally prefer warmer climates. They can withstand occasional short-lived cold spells but not prolonged freezing temperatures.

Watering: Once established, they are relatively drought-tolerant. Water young trees regularly to establish a strong root system. Mature trees are more tolerant of dry conditions.

Soil: They grow well in a wide range of soil types, including sandy or loamy soils, and can tolerate some degree of soil salinity.

Fertilization: Australian Pine trees are not heavy feeders. They generally don't require regular fertilization unless the soil is nutrient deficient. Use a balanced fertilizer sparingly.

Pruning: Minimal pruning is necessary. Prune to remove dead or damaged branches and maintain the tree's shape. Be cautious as the wood is dense and hard to cut.

Pest and Disease Management: They are relatively resistant to pests and diseases. Occasional problems include scale insects or root rot in poorly drained soil. Monitor and address issues promptly.

Propagation: Propagation is commonly done from seeds. The winged seeds can be collected and sown in well-draining soil.

As these trees can grow quite large, consider their ultimate size when planting them, especially in residential landscapes. Australian Pine trees are often used in coastal areas due to their tolerance to salt spray and sandy soils. When providing care, focus on proper watering during establishment and maintaining suitable growing conditions to support healthy growth and development.
