5 Steps to a Better Back Yard

Clover is the secret to having a healthy lawn without chemicals.

clover is the secret to a great organic lawnThe secret to having a great lawn without chemicals is Dutch clover. For the past 50 years, clover has been considered a noxious lawn weed, but before that it was an important component in fine lawns—and for good reason. Clover is drought-tolerant, virtually immune to diseases, and distasteful to common turf insects. And it generates its own food by fixing nitrogen in the soil.

So how did this lawn superstar get such a bad rap? Blame the broadleaf herbicides introduced after World War II. Used to kill weeds such as dandelions and plantains, the chemicals also destroyed the clover that was used in many lawn mixes of the time (leaving ugly bare patches in their wake). Today, virtually all seed companies omit clover from their mixes.

But that doesn't mean that you can't enjoy the advantages of this great green. Eliminating herbicides from your lawn regime is incredibly easy. And once you do it, most clover you introduce into your back yard will thrive. Here's where to start?

Step 1: Kick the fertilizer habit.
If your lawn is already in decent shape—no big bare patches, less than 20 percent weeds—you can make it organic without adding any new clover or grasses. Conversion is not so much what you do as what you stop doing. In other words, throw out your fertilizer. Most commercial synthetic versions are loaded with nitrogen (represented by the first of three numbers in the analysis on the package).

But turf needs a lot less nitrogen than people think. Though you'll see figures as high as 30 percent, it's better to use a less concentrated nitrogen source that lasts longer. So try an organic lawn-food blend such as Concern or Espoma, cottonseed meal, or dried poultry waste. Most of the nitrogen in these is water-insoluble; it stays put and is released over a month or more, providing nutrition to the plant in small doses. Apply it at a rate of one pound actual nitrogen per 1,000 square feet in midspring and again in autumn. (The percentage of nitrogen lawn food varies, so you'll have to do some calculations to figure out how much to apply.)

Granted, your lawn might not turn emerald-green overnight, but you'll find it retains a uniform color through the season. Best of all, it will grow slowly and steadily, loosening those chains that bind you to the mower.

Step 2: Add clover and other grasses.
If you're lucky, you already have some clover in your lawn. If not, it's easy to add it by overseeding, or planting on top of what's already there. In spring or autumn, rough up the surface of the lawn with a metal garden rake. Mix the clover seed with sand or finely screened compost to ensure even distribution. Sow two ounces of clover seed per 1,000 square feet for a moderate clover cover, or up to eight ounces if you want the clover to dominate the turf. After sowing, water your lawn deeply and keep the soil surface moist until the clover germinates. The result will be a soft, cushy, deep-green lawn that stays lush through spring, summer, and fall.

If you can't give up the idea of an all-grass lawn, you can still go organic without clover. Use the same overseeding technique to introduce a low-maintenance turfgrass, such as hard fescue or sheep fescue, to your Northern lawn. In the South, try buffalograss or blue gramagrass. If you're starting over, consider an ecology-lawn mix that incorporates turf-type fescue with flowering plants, such as English daisy and yarrow. More than a lawn but less than a meadow, an ecology-lawn mixture can be mowed and used like turf.
