Traditional turf lawns are the standard even within the arid, desert climate of Utah, but such lawns are not sustainable in practice. Maintaining traditional lawns places significant stress on grass and creates a reliance on constant watering, fertilizer, and pesticide use.
Promoting natural ecosystem mimicry
Reducing the application of fertilizers and pesticides can actually improve plant and soil health. Salt Lake City is promoting methods to create yards that mimic natural ecosystems by allowing organic materials like leaves and grass clippings to remain on the lawn.
Soil health and fertilization tips
To improve soil health and reduce weed growth, residents can add one-fourth inch of compost in early spring and fall or apply a mixture of water and liquid molasses to feed soil microbes. Natural fertilization can be achieved by mulching with leaves and leaving grass clippings on the lawn.
Effective maintenance and irrigation strategies
Effective lawn maintenance includes aerating to avoid compaction and keeping mower heights between 3 and 4 inches. This height helps block sunlight from reaching weed seeds. For irrigation, officials recommend one inch of water per week in May and September, and 1.5 inches per week during the summer, while avoiding watering during the heat of the day.
Alternative ground cover options
Alternative ground covers are also suggested for those looking to reduce lawn space. Options include creeping thyme, which supports foot traffic, Roman Chamomile, moss for shady areas, and white clover. White clover is noted for being drought resistant and providing nitrogen to the soil through its root system.
Recommended drought-tolerant grass species
Selecting site-adapted grasses can further reduce maintenance needs in northern and central Utah. Recommended species include:
Fine Fescue, which is shade tolerant and drought tolerant with low fertilizer needs.
Tall Fescue, which features deep rooting and requires less irrigation.
Kentucky Bluegrass, which is ideal for heavily used yards due to its ability to recover quickly.
Buffalo Grass, which requires minimal fertilizer and can tolerate moderate foot traffic.
Natural pest control methods
To discourage pests, residents are encouraged to declutter yards and homes, remove standing water, and eliminate open food sources. Natural alternatives like neem oil or peppermint oil can be used in place of chemical pesticides.
