Trees are plants that take long time to grow. Some varieties take more time than others. Then you must think in other factors here:
- How long are you willing to wait for the shade or privacy you want.
- When do you expect to have trees that look like real trees.
You can fall in a common mistake. Some trees owners plant younger plants when they want their big shade landscape or their natural privacy system. But they get very disappointing when notice that will have to wait some years to have that garden expectation in their houses.
