Can spruce trees be grown in Australia?

This genus is a member the Pinaceae family and contains approximately 45 species of evergreen coniferous tree. It's also known as spruces. They can be found in temperate and subarctic areas of the Northern Hemisphere.



This begs the question: Where do spruce trees actually grow?

Colorado blue spruce thrives in sunny areas with well-drained and fertile soil. It can tolerate dry winds and adapts to dry soil. The tree can be grown in USDA plant zones 3 through 7. Colorado blue spruce can be planted in a hole as deep as the rootball and up to two- or three times wider.

Second, which type of spruce tree am I using? First, look at the needles to identify spruce tree species. If the needles are attached to individual branches, and can roll between your fingers easily, it's a tree. Next, examine the cones. They are smooth and thin on spruce trees and easy to bend.

How do spruce trees reproduce, you ask?

Every spruce tree has both male and female cones. Ovules are found in larger female cones. These ovules then develop into egg cells or female gametophytes. reproduction requires that the male gametophytes are able to reproduce through the release of pollen grains from the smaller cones. The pollen is carried by the wind to fertilize the eggs in the female cones.

How long does it take for a spruce to grow?

A Sitka spruce can grow to 160-200 feet in its 500-year lifespan. It will also reach maturity at 60 inches per year. The Norway spruce is second, with an average annual growth rate of 30 inches. It stands between 40-60 feet and has an impressive but manageable height.
