Earth‐Kind Environmental StewardshipWhat is Environmental Stewardship?
• Environmental stewardship is the responsibility for environmental quality shared by all those whose actions affect the environment.
• Source: www.EPA.gov
2
Earth‐Kind Principle:Plant Selection
• Using well adapted plants is one of the most fundamental elements of an Earth Kind landscape.
• Plants that are well adapted to your area will:
– Use less water
– Need less soil modification
– Require little or no fertilizer
– Less susceptible to pest, diseases, and problems
– Be more tolerant of stressful environmental conditions
3
Earth‐Kind PerennialsResearch Program
• Purpose:– Environmental Stewardship
– Evaluate herbaceous perennials without the use of fertilizer and pesticides, with limited supplemental irrigationirrigation
– Utilize the Earth‐Kind Soil Management System to improve soil properties, fertility, and health, reduce weed pressure, and conserve soil moisture
– Collect scientific data on the plant performance to identify superior plant material for the landscape that requires low maintenance
4
Earth‐Kind PerennialsResearch Program
• Earth‐Kind Soil Management System:
• Add 3 inches of compost and till 6‐8” deep
• Add 3 inches of wood mulch to the soil surface
• Maintain a 3 inch layer of mulch• Maintain a 3 inch layer of mulch
5
Earth‐Kind PerennialsResearch Program
• Steps:– Pesticides and Fertilizer
• No synthetic, natural, or organic pesticides or fertilizers will be applied to the plants or the soil during the duration of the trialduration of the trial.
– Maintenance• Limited Maintenance!
• Through these field trials, identification of plants that have low maintenance requirements is significant. Any maintenance that is required for each test plant should be documented on data collection forms.
