In Pursuit of the Perfect Lawn
by Ruth S. Foster
Lawns are really thousands of tiny plants, each crying for attention. A perfect lawn depends on constant care ..... regular mowing, fertilizer, water, monitoring, maybe chemicals and lots of tough love. The question to ask yourself is "how perfect do you want your lawn to be?"
While researching how sod is grown, the farmer said, "Those riding mowers are grownup toys for men. There's testosterone in them there tanks."
Nurserymen say women customers buy flowers, while men buy lawn stuff and leave. This was reinforced by a garden magazine editor who said that men are into grass while women prefer flowers and sentimental things.
So this column is for guys. It's about grass. Almost everyone has a small chunk of something flat and green. Some folks want that patch to look like a lawn, some even want it to look like a putting green. Which is more of a challenge than a birdie.
The sad unvarnished truth is that lawns are really thousands of tiny plants, each crying for attention. A perfect lawn depends on constant care ... regular mowing, fertilizer, water, monitoring, maybe chemicals and lots of tough love.
Fortunately, there are varying degrees of perfection, so even if you don't do all these things the professionals do, the grass will still grow, and be your greensward.
So let's count the ways to make a perfect lawn for cool areas.
Cleanup First thing in spring, rake the lawn. Rough up bare or thin spots and add grass seed. Sprinkle them with a little special starter fertilizer, high in phosphorous (P), if you have it.
Fertilizer Apply fertilizer three or four times a year, starting in early spring, again in mid-May, then around Labor Day, and finally an organic fertilizer in late fall. But beware, too much nitrogen makes thin cells walls and fragile grass. Use only the right amount, more is not better. Iron (Fe) makes grass greener. Potash (K) makes it tougher. There are many, many fertilizers for each phase of growth and for each season, as well as alternative lawn care programs that add plant hormones and beneficial organisms.
Lime Grass likes a pH 6 to 6.5. Lime is usually needed only every few years, but test the soil first.
Mowing Start mowing when the the spring shoots get 3 to 4 inches high. Try to remove no more than 1/3 of the green shoot at each mowing. Current theory is that mowing high ( about 3 inches) shades out weed seeds, especially crabgrass. For a perfect lawn, mow regularly and often. Keep the blade sharp.
Mulch the Clippings Best for the lawn is to let chopped up, small grass clippings stay on the lawn to compost and return nutrients to the soil. The fastest way to mow is in a big circle, not up and down with many turns. However, if you love your lawn, you probably prefer a particular pattern to the mowing lines.
Crabgrass There exists a passionate hatred for this spreading greenery whose seeds germinate over a long period of time. Pre-emergent herbicide control may be applied (with fertilizer) in early spring, however, herbicides may not be a good idea where there are children or dogs. An alternative safe crabgrass control (made from corn gluten meal) is available but has to be re-applied for two or three years to get reasonable results. Combined with mowing high, overseeding spring and fall, aerating, and yes, hand pulling of the light green seedlings, crabgrass can be kept under control.
Pesticides Use them only when needed after a particular problem has been identified. Then treat just thatproblem. There are lots of books on the subject or get professional help. Fortunately, there is a new, safer pesticide called Merit for white grubs in the lawn. (Grubex is the same thing.) Apply it in May for control of the new grubs which will hatch in summer. It works slowly and is most effective on small grubs.
For more immediate insect control, one can apply a strong chemical pesticide (after identifying the insect). But remember, if children or dogs play on the grass, they will be exposed. Better to let the kids grow up first.
Water and Sprinkler Systems Ideally a lawn likes one inch of water about once a week to encourage deep, healthy roots. Fight to get your sprinkler company to cut your frequency to once a week, twice at most. Overwatered grass is shallow rooted, fungus prone, soft and fragile. Have a manual sprinkler override to turn it off when rains are heavy and don't begin irrigating until the first long heat wave in late May or June. If you pay for sewer charges based on how much water you use, try to get your sprinkler system on a separate water meter. It will save sewerage charges.
Fine Tuning Aeration (making holes for air in the soil) helps a compacted lawn so, if you own some, wear spikes when you work on the lawn. Topdressing with a fine compost or topsoil helps too. Current theory suggests that a late fall application of organic fertilizer will melt thatch.
Overseed Lawns grow best in the cool of spring and fall, so twice a year regularly apply grass seed at the start of each growing season to replace all the little grass plants that didn't get all the love and attention they were crying for.
But what if you don't care about having a perfect lawn?
If all the above sounds too daunting, here are some simpler ways to manage a lawn, if you can accept a lesser degree of perfection:
Fertilize Less Apply some fertilizer around Labor Day if you only want to fertilize once. If you're willing to fertilize twice, apply it in spring just as the grass starts to grow. Or don't fertilize at all and just mow the green weeds and wild flowers which will spring up. The lawn will not look like perfect wall to wall carpet, but will have interesting color variations.
Mow and Mulch Definitely leave the grass clippings to mulch in the lawn, which saves collecting them. Leaving the clippings add enough nutrients to equal two fertilizings. If you don't get around to mowing often enough, mow over the bigger clippings two or three times to chop them up.
Water Less Water when there is a drought by soaking deeply. Use a can or jar to measure when the water reaches one inch. Or let the lawn turn brown, which it will do naturally during summer's heat. A little rain will green it up again.
A Wild Flower Lawn While this sounds easy, it's not but requires as much work as growing vegetables. If wild flowers appear of their own accord in your grass, you can mow around them while they are in bloom if you wish. When they finish flowering or get too long and straggly, just mow over them. Dandelions, butter and eggs, clover, hawkweed, violets, johnny-jump-up, Queen Anne's lace, cinquefoil, English daisy and ajuga are some of the flowers that may appear.
