Lawn Care for the 21st Century

Posted May 15, 2015 2:34 PM by BestInShow

An old advertisement for the now-defunct Oldsmobile division of General Motors had the tag line "not your father's Oldsmobile." Do you tend your lawn, or your business's lawn, the way your father taught you? Good news: lawn care is changing, becoming simpler, less expensive, and more sustainable.

IHS Engineering 360 recently sponsored a presentation with a local garden/lawn care expert. Instead of conventional lawn-care "wisdom," much of which originates with seed and fertilizer companies, we came away with a trove of solid, lower-impact methods for establishing and maintaining a good stand of grass. Here are a few examples.

Weedy lawn. Photo from Gardendaze's blog, Karla A. Dalley, author. Use is licensed under a Creative Commons License.

  • Use common sense
    • How many weeds do you have in your lawn? Not too many? Then don't waste time and money applying a "weed and feed" product. Pull the weeds by hand, or use a sprayer to zap weeds with weed killer. And follow directions on the weed killer: applied too early, it won't work.
    • Lots of weeds? Use a strategy that keeps weed seed from germinating, such as applying corn gluten meal in the early spring to knock out crabgrass. Germinating crabgrass seeds can't penetrate this covering, so they never get a chance to take hold. Use weed killer on perennial weeds - like dandelions - since killing seeds won't kill established plants.
  • Water correctly
    • A little water every day is not good. An inch of water once a week is just right. If Mother Nature takes care of this, great! If not, water only as much as your grass needs to be watered.
  • Fall is the best time to prepare for next spring
    • It's easier to prevent weed seeds from germinating than it is to eradicate the resultant weeds. Put down corn gluten in spring and fall.
    • Establishing a new lawn or rejuvenating part of an old one is best done in the fall. You'll have a lovely green lawn sooner in the spring.
  • Pick the correct grass variety for circumstances.
    • Don't plant bluegrass in shady areas; choose a variety recommended by your Agricultural Extension Service for your local conditions.
  • You don't have to spend a lot of money
    • Need a rain gauge? Use a tuna or cat food can. Mark an inch. Use when it rains and when you're watering your lawn.
    • Want to kill off a weedy patch of lawn before you replant? Or kill off some grass for a new flower bed? Cover the area with cardboard. You can put some mulch on top to look pretty. The cardboard will break down over time, leaving you with a pristine plot for new planting.
    • And follow directions on fertilizers, weed killers, grass seed - you'll save money and frustration if you use your supplies effectively.

Tuna Can Rain Gauge

f you're not a fan of turfgrass, stay tuned. Next week's blog will examine how we got hooked on growing perfect lawns.

From what I have seen in the news lately, a green lawn will become a scarcity, especially on the west coast. Unless you are a celebrity.

A lot of the search results I got for "lawn replacement" come from California: municipalities, the state extension service, private landscape companies, garden blogs. Some of the lawn care water-use statistics I've found are jaw-dropping. This is from a 2012 publication of the University of Delaware Agricultural Extension Service -> Across the United States, over 7.9 billion gallons of water are used on landscapes each day, primarily on lawns-and most often this water is fresh and potable.

Guess it depends on Can Size: From our trusty friends over at the FDA and as noted in 21CFR161.190:

"For the purposes of this section, cans of dimensions 211 * 109 shall be deemed to have a water capacity at 68 deg. F of 3.55 avoirdupois ounces of water; cans of dimensions 307 * 113, a water capacity of 7.05 avoirdupois ounces of water; cans of dimensions 401 * 206, a water capacity of 13.80 avoirdupois ounces of water; and cans of dimensions 603 * 408, a water capacity of 68.15 avoirdupois ounces of water."

I'm confused! If tuna are salt water fish and rain is fresh water, or at least most of it, how do the tuna swim out of the can to let the rain in the can? If they can't swim in fresh water, how many cats does it take to empty the tuna can before the storm comes? Which would eat the tuna faster, the feral cats or domestic cats? Cats don't like water or rain so you better get the fastest cats in the neighborhood to get your rain gauge ready for the rain!

Good Luck, Old Salt
