Compost material should be well composted and free of viable weed seeds. Fresh manure should not be used due to high bacteria and nutrient levels.
Add 2 –4 inches of compost across landscape surface area and till into the top 6 inches of soil.

- Mulch receipts
- Plant receipts or contractor invoice. If receipts are not available, close-up photos of plants.

2-3” Double-shredded hardwood mulch
Planting should aim for 100% coverage at maturity. Aim for about one plant every 2-4 square feet for herbaceous plants, with more space provided for trees and shrubs. It is important to consider conditions at the site, such as exposure to sun, soil type, moisture, aesthetics, and wildlife objectives when selecting the appropriate plant species for a conservation landscape. Plants must be native. For plant options: https://www.plantnovanatives.org/

Tips for success:
- Take photos in summer during growing season; take all required photo types.
- Recommended maintenance for your conservation garden:
- Mulching can improve soil health and limit weed growth.
- Maintaining an edge or border around the conservation garden.
- Weeding as needed.
- Trees and shrubs may need pruning.
- Depending on the species, perennials may need deadheading (removing dead flowers from plants).
- In periods of little or no rain, any new plants may need to be watered.
- Typical reasons for denial of re-certification: planting area overtaken by weeds and/or grass; photo documentation does not show plants during growing season.
