Smart Mountain Lawns

 

Our Truckee Donner PUD irrigation days are Tuesday and Friday and lawn's are our largest outdoor consumer of water yet they are not as bad as they are often made out to be. They clean volumes of air pollutants and dust and they produce vast amounts of oxygen and they give us an outdoor room where our children can run. (“Plant containers, trees, shrubs, groundcover, and vegetable gardens may be watered as needed when using automatic drip irrigation or hand watering.”) Please Share this.

My lawn tips: • Keep lawns small. Sheet Mulching is an easy method of reducing your extra turf without injuring tree roots. Mow tall and leave the clippings. Lawns mowed to ≥3" use less water, have far fewer weeds, require less fertilization and require less frequent mowing than short lawns. The longer blades photosynthesize far better (feeding and encouraging deeper roots) and they shade the soil surface (reducing temp's, moisture loss and impeding weed growth). • Aerate and Topdress (with a deep-tine or plugger aerator - Truckee Rents) twice a year (or at least once) and then top dress with your own mature compost or bags of Kellogg Topper (a fine screened mature compost). Aeration opens compacted soils and allows for deeper water penetration and better aeration (healthy soils, roots, microbes NEED oxygen). Topdressing compost adds humus that helps soil hold much more water, reserve nutrients and supports microorganisms that break-down lawn clippings, digest & excrete organic fertilizers and protect the lawn from pathogens. We apply 2cu.ft. over 200 sq.ft. and it defies logic that it helps as well as it does. It really helps lawns retain moisture through the summer. • Use organic fertilizers. We usually apply BIOSOL (food-grade organic cottonseed & soy meals that have been completely digested by fungi :) in fall. Biosol seems to minimize rodent damage under snow in "normal" winters and releases throughout the rest spring and summer. We use G&B Organic Lawn Fertilizer in spring (and at a lighter rate every time we aerate & topdress) to give lawn a little boost while the living microorganisms in the fertilizer go to work digesting the brown straw (no, it's not "thatch") left over after every winter. • Water deeply and infrequently. In a normal summer I'll water 3 days a week in July & August but 2/week June & Sept. and occasionally, as needed in the shoulders. This summer I'll water Tuesday & Friday. Break-up your irrigation on watering days. For example, if you put your gauge out on the lawn and found it takes 30 minutes to apply 1/2" of water, then water for 10 minutes at 5am, 10 min at 6am and 10 min at 7am. Like a light rain, the first watering, wets the soil, breaks the surface tension and allows the next watering to go deeper without running-off, the third, allows water even deeper into the soil. Do not water for 10 minutes at 5am, 10 min at hood and 10min at 5pm as the moisture will simply evaporate & transpire without getting to the deepest roots that you are really trying to encourage.  This is especially important if you have any slope to your lawn or if you planted sod (often grown in dense Nevada clay). Syringing is a technique, used in the hottest weeks, where we apply 1-2 minutes of water to the lawn, near the hottest time of day (on your lawn) in order to cool the grass blades, increase humidity and halt evapotranspiration (moisture loss) for a few hours which actually saves much more water than it uses. On those Tuesdays & Thursdays, in July & August, you might try this at ~about~ 2:00pm.  Watering late in the day is generally discouraged because moist leaf surfaces at night invite disease.  • If you have dandelions it is a strong indicator of poor soil (bluegrass in rich soil, will not allow many weeds). Aerate & top dress more frequently and avoid chemical fertilizers.  There is a relatively new natural selective herbicide (Natria) of chelated iron, that kills broadleaf plants in lawns without killing grass.

Bluegrass can go many months without water in a summer dormant state and come back to life when moisture returns. Turf-type Tall Fescues are slightly more drought tolerant in a daily basis but will die in a month without any water. Fine Fescues Meadow Blend (meadow-like grasses) are shade tolerant and can stay green on once a week watering and once a month mowing. Native Grass Blend is six species we selected for relatively short growth, drought tolerance and the ability to thrive when grazed (or mowed occasionally). Clover added to a lawn at 1/4-1/2 lb / 1000 sq.ft. reduces the lawn's need for fertilizers, improves the color of the grass and the lawn as a whole, improves the soil, and is NOT a weed in lawns. Bluegrass is a weed, that's why it makes such durable turf.
