IV. Interest Approach:

* Show a picture of the water cycle.

- Ask s’s, “What is this a picture of?

- What is the water cycle? How does it work?

- What types of plants grow in these different areas?

* Bring out a group of plants- pictures- which are used in a xeriscape. Ask the s’s, What do all these plants have in common?

|BR (bare-root): dug from nursery field, soil washed from roots. |B1. Pictures |

|B&B (balled and burlapped): dug from nursery with ball of soil around roots, wrapped with |OR |

|burlap and wire basket. |B2. Overheads, PP |

|List the four different factors related to selecting the proper plant; | |

|Role Factors | |

|- architectural element: wall, ceiling, or floor | |

|- USDA Hardiness Zone |C2. PP, Overheads |

|- Microclimate | |

| | |

| | |

|Physical Factors: | |

|- Mature Size and Rate of Growth | |

|Define and describe the purpose of Xeriscaping; | |

|Xeriscape (zeer-escape) - used to describe techniques of landscaping that conserve water. | |

| |**Show pictures of those plants |

|List the economic, environmental, and aesthetic benefits of Xeriscaping; |that have overgrown there area. ** |

|Saves water & money | |

|less fertilizer | |

|Less time mowing lawns | |

|Use of native plants | |

|Aesthetic designs | |

| | |

|Explain the seven principles of Xeriscaping; | |

|Proper planning and design | |

|Soil analysis | |

|Appropriate plant selection | |

|Practical turf areas | |

|Efficient irrigation | |

|Mulching | |

|Appropriate maintenance |D1. Pictures/ Book |

| |OR |

| |D2. PP., Overheads |

| | |

|Apply the principles of Xeriscaping to landscape design; and | |

|Limit areas of lawn, use fescue blends, water 1x/week 6-8” deep. | |

|Group plants together with similar water requirements in sprinkler zones. |E1. Pictures, Book |

|Design water conservative irrigation systems. |OR |

|Water just to meet plant needs, preferably in the early morning. |E2. PP, Overheads |

|Do not water non-growing areas (decks, concrete, fences, etc.). | |

|Select drought tolerant and native plant species. | |

|Plant trees and shrubs to shade the ground, use water-retention rings. | |

|Plant windbreaks to protect plants from desiccation. | |

|Consider interior climate control to save energy for the home (place deciduous trees on south | |

|and west sides of house, use foundation plantings). | |

|Amend the soil with organic matter & apply 3-4” of mulch to planted beds. | |
