Course description
This is a one-semester introduction to the applied plant and soil sciences necessary to managing gardens and landscapes sustainably. Students will learn how to assess the site and soil conditions necessary for proper plant selection. Next, they will discover the proper way to prepare both plants and soil for installation designed to maximize root establishment. Finally, students will develop the ability to diagnosis signs of biotic and abiotic stress in landscapes and determine the best treatment. Throughout the course students will be exposed to the numerous myths and misperceptions prevalent in the fields of landscape horticulture and arboriculture.

Grading
Your grade is based on 1000 points, 600 from three one-week-long individual projects,300 from your participation in the weekly discussion forums, and 100 for a critical analysis of a university extension educational resource.
- Projects (3 @ 200 points each = 600 points)
- Discussion forum (15 weeks @ 20 points each = 300 points)
- Extension information analysis (100 points)
