Texas FFA Nursery Landscape Practice Exam

At what depth should a transplanted tree or shrub be set in the ground?

1. At the same depth at which it was originally growing

2. 50 percent deeper than it was originally planted

3. With the top of the container slightly covered

4. So that the top roots are exposed to the air

The correct answer is: At the same depth at which it was originally growing

Setting a transplanted tree or shrub at the same depth at which it was originally growing is vital for its health and successful establishment in the new location. This practice ensures that the root crown—the area where the roots meet the trunk—remains above the soil level, which is crucial for several reasons. When a plant is buried too deeply, as might happen if it is set deeper than its original growing depth, the trunk can become susceptible to rot and disease due to excess moisture and lack of air. Conversely, if the plant is not buried deep enough or if the roots are exposed to the air, they can dry out and become damaged, hindering the plant's ability to absorb water and nutrients. By planting at the same depth, you allow the tree or shrub to adjust naturally to its new environment and maintain its physiological functions appropriately. It promotes better anchorage and support in the soil, aids in efficient water uptake, and ensures that the plant can thrive as it establishes itself in its new location.
