Upon successful completion of this course the student will be able to:
1. Select quality trees and other woody plants for optimum performance in the landscape.
2. Evaluate the planting site to determine how plants will respond and/or how to mitigate site conditions.
3. Prepare a site to improve plant performance and ease of maintenance.
4. Recommend proper use of staking or guying for newly planted trees.
5. Compare and contrast planting and transplanting methods for a variety of trees and shrubs.
6. Determine nutrient needs and toxicity problems for woody plants and recommend treatment to correct nutrient deficiencies.
7. Evaluate factors that affect water use by plants and determine minimum water needs and methods of applying water.
8. Manage soil conditions for favorable plant growth.
9. Describe basic concepts of pruning and current pruning standards.
10. Evaluate tree structure and response to pruning.
11. Describe the role of growth regulating hormones in maintaining a favorable root to shoot ratio.
12. Determine which plant growth 'stimulants' and soil applied amendments work and which do not.
13. Evaluate environmental and biological factors that increase susceptibility to insect and disease pests and influence tree failure.
14. Describe structural defects that increase hazard tree potential.
15. Discuss the methodology and current technology for assessing and mitigating tree hazard potential.
16. Decide on best management practices for maintaining landscape trees and plants.
17. Summarize concepts of fire-safe landscaping.
