Use the mulch technique in selected areas to establish natural plantings.
- In relatively small island plantings
- In manicured areas
- To form an edge to a native or naturalized plant community
- In close proximity to residential or formally maintained areas where dense planting is desired as a visual or sound barrier
- Eliminate grass and herbaceous plants through herbicides (for example, Round-Up).
- With a sod cutter, cut an area that will contain the mulch and provide a well defined boundary.
- Spread mulch to a depth of 10 cm (3 inches).
- Monitor the area for a growing season to ensure grass and weeds do not return. Spray or pull any that do.
- After one growing season, plant the area with a selection of native plants. Consider the soil, moisture availability, exposure. before choosing plants.
The mulch technique will:
- Reduce weed invasion and establishment
- Improve growing conditions by conserving moisture and maintaining even soil temperatures
- Result in faster growth and establishment of native plantings
- Enhance the look of the area as the plantings are established
- Reduce maintenance costs (for example, less weed control required, reduced need for watering)
