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.
