Lawn Sprinkler Background The lawn sprinkler is a mechanism through which water is distributed in a spray so that a residential lawn or garden is irrigated. Sprinklers may take extraordinarily large forms, such as the irrigation systems used by professional farmers to water crops in the field. Many serious gardeners employ landscaping firms to develop and install expensive, permanent sprinkler systems in the ground. However, the average American simply purchases an inexpensive plastic and metal sprinkler and attaches it to a garden hose so that the sprinkler disseminates the water evenly. Residential use lawn sprinklers take a wide variety of forms and are available in a wide variety of materials and associated prices. However, the oscillating sprinkler, with a metal arm that sprays out a fan-shaped curtain of water in an area approximately 600 ft2 (55.7 m2), is likely the most popular. Such oscillating sprinklers sell for well under $10, but can be over $40. The permanency of the materials generally determines the price.

The less expensive, plastic and aluminum oscillating sprinkler is very simple in construction and in operation. Most include only a base that enables the piece to seat securely on the lawn, an oscillating arm, a bracket with regulating cam (it controls the width of the fan spray as it moves the spray arm), the mechanical motor, and the connectors to the garden hose. The oscillating sprinkler works on the principle that water provides the power to move the elliptical cam (or heart-shaped cam in some models) which moves the sprinkler arm. Water spins a simple turbine which must be attached to a series of gears stacked up (called a gear train) to slow down the speed of the water.

Without the insertion of the gear train the cam and the oscillating arm would move much too quickly. The gear train reduces the speed of the incoming water so that the cam moves at only about one mile per hour.

History The advent of the residential lawn sprinkler is inextricably bound with Americans' desire to cultivate the yard for fun and aesthetic reasons and not for farming purposes. In fact, Americans of the seventeenth and eighteenth centuries did not think much of developing bucolic spaces in and around their homes. The town square in New England, now gorgeous green pastures, was a scruffy piece of land in which cattle could graze. In the nineteenth century attitudes toward the cultivation of the lawn change for two reasons. First, more Americans moved out of the city to the evolving suburbs as rail transportation enabled them to live further from places of business. As they moved out where there was space for gardens there was the urge to work the lawn as a hobby. Beautifying the home and garden were thought to strengthen the family. Secondly, Victorian Americans began to long for the rural New England they thought they were losing while others wanted to emulate the pastoral estates developing in England. Notable landscape architects urged Americans to beautify their property and published treatises and designs to help them achieve this goal.

Lawn sprinklers require a city water delivery system because they are generally used with a hose. Such systems were not in place in large measure until about 1870. The very wealthy used fountains to water the lawn and dazzle neighbors. Patents on lawn sprinklers follow in short order; the first patent on an American lawn sprinkler was issued in 1871. Hose reels, nozzles, and sprinklers were advertised by 1900. Sprinklers took various forms. Large contraptions that rolled on carts with immense yardage of rubber hose were popular with some in the early twentieth century. By about 1930 the mechanisms took other forms such as cast metal with a three or four-arm rotating head that shot water as it spun around. Some were formed in the shape of animals with a rotating arm on the top. Plastic-bodied sprinklers followed in the later 20th century.

 A plant's ability to survive-and thrive-in your garden depends on the quality and condition of the soil. It needs to have good water drainage, yet hold just the right amount of water and nutrients. It also needs ample pore spaces to hold air. Good soil is your best guarantee for a healthy garden. Here's how you grade your own soil: First, find out what your soil is made of. Take a sample from the top 6 inches of your garden's soil. Put it in a jar; fill the jar with water; and cap it, shake it, and let the mixture settle. It will settle into three distinct layers. Sand, the heaviest, will settle to the bottom; clay, the lightest, will sit on top; silt will be in the middle. If you have roughly equal amounts of each of these layers, your soil is in good shape. If there is more sand or clay, you will need to improve the soil. The drainage in soil is determined by the soil's texture-the size of the soil particles. Clay soil is composed of tiny granules that stick together. You can roll clay soil into a firm ball that feels smooth and sticky. Sandy soil has large sand particles you can see; it feels coarse and gritty. You can't form a ball with sandy soil. It also doesn't hold water or nutrients very well. Loam, the ideal garden soil, is a good mixture of sandy soil, medium-size silt particles and clay. You can determine how well your soil drains with this simple test. Dig a hole about 4 inches deep. Fill the hole with water to saturate the soil around it. Wait for the water to drain. Take a tin can with both ends removed and push it down into the hole (see photo at right). Note the time you insert the can. Fill the can with water and see how long it takes to drain. If the water is gone in less than an hour or if it takes longer than five hours, your soil needs some organic material added to it. How do you fix a soil problem? Adding organic matter, or humums, is usually the best solution. It makes the soil soft, crumbly and workable. Soil that is high in organic matter drains well, and warms up and dries out faster in the spring. Peat moss is one source of organic matter that's readily available. Apply about 1 to 2 inches of peat moss to the soil in the spring or fall and work it into the top 6 inches of your soil

Weed-free lawns are the stuff of dreams and championship golf courses. In fact, when you consider the tenacity of weeds, it's a wonder any of us win the pitched battles we wage with these pesky invaders. Just one dandelion plant makes up to 15,000 seeds, each of which can survive six years in the soil—creating 15,000 more seeds when it sprouts and matures.

Synthetic herbicides are the usual response to chronic weed problems. But used unwisely, these chemical weed killers can be dangerous to people, pets and turf. And unless you get at the underlying problems that weaken lawns and favor weeds, you might have to apply herbicides frequently.

The best way to control dandelions and other weeds in your yard is to grow a thick, vigorous lawn. Dense grass crowds out weeds and blocks the sunlight their seeds need to germinate. If only a few weeds dot your lawn, changing your maintenance tactics might be all it takes to get rid of them. And if your efforts at hand-to-hand combat haven't worked, take heart. There really is a way to pull out even stubborn dandelions so they don't come back.

PLAN YOUR APPROACH
No single herbicide, weeding technique or lawn care tactic works against all weeds. How you attack the weeds in your lawn depends on which you have. Lawn weeds fall under three broad categories: unwanted grasses; grasslike plants called sedges; and broadleaf plants. Most are annuals or perennials. Annuals complete their life cycle in one season and reproduce from seeds. Perennials live several years and spread underground as well as by seed, making them harder to control.

Healthy Beginnings:  No amount of watering or fertilizer will compensate for improper planting. On many occasions I have puzzled over the problems of plants only to discover they were planted six inches too deep or with their roots bound tightly. There isn't any mystery to good planting, just some common sense techniques. Dig the Hole FirstBefore you unpot your plant, prepare a hole fifty to a hundred percent larger than the plant's root ball. Work some compost, peat moss or other soil conditioners into the soil you've removed. When planting smaller perennials or bedding plants, rather than preparing individual holes, it may be simpler to amend a larger area and use a trowel to place the individual plants. In the case of large trees, it is generally best not to amend the soil too much. The roots of the tree will try fairly quickly to spread past the prepared area, and if the composition of this soil is significantly different from that of the surrounding area, the roots can have trouble getting past the barrier. If the tree is going to have to survive in a primarily clay soil, you won't be doing it any favors by creating a super-rich loam immediately around the root ball. Just Deep EnoughPlace some soil in the center of your hole creating a mound. Generally, you want the soil line to be at the same point it was in the pot. But since the loose soil you'll be using to fill your hole is bound to settle some, start with the plant sitting a little higher. Then when it settles it should be at the correct height. It is usually better to err on the side of having the plant too high rather than too low. Some plants, like rhododendrons, actually like to sit with the top of the root ball an inch or so above the soil line, especially if you have a slow-draining, clay soil. When the hole is ready, unpot the plant. Hold it upside down, and with one hand holding the plant in place, hit the bottom of the pot with the palm of your other hand. Now make sure the plant isn't root-bound. If the roots have formed a solid wall around the inside of the pot, you'll need to gently loosen them or carefully score the outside layer. If planted with the roots left constricted, the plant is unable to send out new roots beyond this barrier and can actually strangle itself. As you place the plant in the hole, try to gently spread the roots atop the mound of soil. Unwrapping BurlapIf you're planting a large shrub or tree that's wrapped in burlap, place the plant on your mound of soil and then untie the burlap. Lean the plant in one direction and pull the burlap underneath it as far as you can. Then lean it in the opposite direction and you should be able to pull the burlap out. At this point it will be much easier to pull soil out from under a large plant than to try to put soil underneath it. This is another good reason to make your mound of soil rather tall to start with. As you fill in the hole around the plant, leave an indentation, or shallow moat, around it and fill this with water. After it has drained, fill it again several times. The purpose of watering at this time is not just to dampen the roots, but to help the soil settle and fill in any underground air pockets that might have formed. You can now fill in the moat with soil and mulch around the plant. Leave a gap in the mulch around the stem or trunk of the plant to allow air to circulate and prevent rot.

It's only been just over a hundred fifty years since grass was cut with a hand scythe - if it was cut at all. That was about the extent of lawn and garden tools then. Now, there are a dozen tools - some hand, some power, that are considered essential for keeping that green carpet in shape.

A lawnmower is the most basic. It's odd to think of a living organism as needing to be sliced to stay healthy, but as a professional gardener acquaintance once said 'Grass likes to be cut'. To accomplish that, a good lawnmower is a necessity. Though among the more expensive items in the tool set, if maintained well it will last forever.

Keep the blade sharp, the spark plug clean and (if it has one) the air filter changed. Change the oil as you would on a car, every season.

Keeping the lawn neat is almost always a matter that can't be completely carried out just by mowing, though. A trimmer or edger is needed. The two basic types are the old-fashioned two-blade models with a long handle. Running the blade alongside patio bricks, steps and other edges keeps the lawn trim and looking good.

The other type is a powered whirling device that shoots a plastic string out a few inches. The string whacks off grass or other plants wherever you aim it. They're lightweight, inexpensive and can last for years, though the coil of plastic string needs to be replaced every couple of months. At a cost of only a few dollars, it saves a lot of effort.

A spreader or two is vital for evenly laying out fertilizer, weed killer and other compounds that help keep the lawn weed free, healthy and looking great. One sort is like a small lawnmower with no blade, just a tub with small holes and a roller that dispense material. Easy to use and long lasting, they're adjustable for a variety of applications.

The second type of spreader is a hand-held unit, usually plastic with a rotary handle. They're perfect for specialized applications of seed for patching small lawn areas, distributing dry fertilizer beads and so forth.

A rake is handy for more than just piling up leaves in the late fall. Though it's important to use for that. Leaves left on the ground can cause grass to overheat or get too little water. In areas that get winter snow, at the end of the season the grass will be compressed into thatch.

Blades will overlay one another, preventing air from reaching the soil efficiently. De-thatching can be done with a power tool, but a simple hand rake is also effective.

1. MOWING: An unsharpened lawnmower blade will actually rip or tear the grass rather than provide a clean even cut. The ripping or tearing of the plant tissue can create a breeding ground for disease and other problems. Cutting your lawn too short is another common mistake that can create an environment that encourages weed growth, increases heat stress during dry or hot periods and makes your lawn more susceptible to insects and disease. Recommendation: Always keep your lawnmower blades sharp. At the outset of each growing season, sharpen the blades or have your blades sharpened by a professional. If you live in a warmer climate, where lawn care is a year-round activity, check your lawnmower blades periodically to make sure they're sharp. Set your mower blade to a height that cuts no more than the top third of the grass plant; this will encourage stronger roots. Cutting your lawn too short not only creates an environment for both weeds and disease it causes the lawn to lose moisture much quicker.

2. WATERING: Water is essential to all life . . . too little water and we die, too much and we drown. The same is true of the grass in our lawns. Water makes up 70% to 80% of the weight of our lawn grasses and the clippings alone are nearly 90% water. While most people are concerned about not watering their lawns enough, the fact is, more lawns are damaged or destroyed by over-watering then underwatering. 

Recommendation: Use water wisely and practice water conservation. To establish itself, freshly seeded area or newly installed turfgrass sod has very important watering needs. Proper watering immediately after installation will ensure the turf gets established, and it will also have an impact on how well the lawn continues to flourish for years to come. Give your new sod lawn at least 1 inch (2.5 cm) of water within 1/2 hour of installation. Water daily or more often, keeping turf moist until it is firmly rooted (about 2 weeks). Then less frequent and deeper watering should begin.

The amount of water required for an established lawn will be determined by its overall health, beauty and ability to withstand use and drought. One inch a week is the standard water requirement for most lawns; however, this will vary between different turf species and even among cultivars within a specie. There will also be varying water requirements for seasonal changes and still more differences brought about because of different soil types. Some helpful advice, look at your lawn to determine if it needs water. Grass in need of water will have a grey-blue cast to it. Also, foot prints will still be visible after a half-hour or more on a lawn in need of water, while on a well watered lawn foot-prints will completely disappear within minutes.

You can also use a soil probe, such as a screwdriver or large spike to determine how dry your lawn is. If the probe can be pushed into the soil easily, it's probably still moist, but if it takes a lot of pressure to push in, it's time to water.

Remember too, just because your lawn turns brown during extremely dry periods doesn't mean it's dying; grass will go dormant during such periods. Your lawn doesn't have to be green to be healthy.  Most grasses can survive 30-60 days of drought without substantial losses.

3. FERTILIZING: A few of the biggest mistakes made when it comes to using fertilizers is not only using the right mixture, but using the right quantity and applying it at the right time of the year. Often times when spring comes around people feel a need to fertilize their lawns in hopes of seeing a green plush lawn as soon as possible. Too much fertilizer, especially with high levels of soluble nitrogen fertilizer, tends to increase thatch problems and leaves lawns more prone to insect and disease. Or, worse yet, you will literally burn your lawn.

Recommendation: The goal of a good fertility program is to produce a reasonable amount of top growth, but not at the expense of root growth or carbohydrate storage. A good root system is the key factor to a healthy lawn.

Nitrogen (N), Phosphorus (P), Potassium (K)
Lawn fertilizers typically contain these three nutrients, although other nutrients may be included in small amounts. The three numbers on the fertilizer bag represent the percentages of N, P, & K-in that order. The back of the fertilizer bag should show the guaranteed analysis. Always follow the recommended application rates suggested by the manufacturer on the bag.

The grass plant needs more nitrogen than any other nutrient. Nitrogen is part of the chlorophyll molecule and helps give the lawn its deep green color. Nitrogen also tends to promote high leaf growth rates at the expense of root growth. Phosphorus is responsible for the energy transfer systems in the plant and is generally required in much smaller amounts than nitrogen or potassium on an established lawn. The exception is for newly established lawns by seeding, sodding, or sprigging, when the need of phosphorus is higher in the new plant. Potassium has a lot to do with good cell wall development and the plant's ability to withstand stress, disease, and insect damage.

Look for slow-release forms of nitrogen. The two basic forms of nitrogen that can be used as a fertilizer are organic and inorganic. The most commonly used inorganic forms of nitrogen in fertilizers are ammonium nitrate and ammonium sulfate. Both are soluble, quickly available forms of nitrogen and both tend to produce a fast increase in leaf growth for a fairly short period of time.

More and more, the slowly soluble or slow-release organic forms of nitrogen are being recommended by turf experts. These include sulfur-coated urea, urea formaldehyde, I.B.D.U., methylene urea, natural organics, and resin-coated urea. These tend to produce a lawn with good color without excessive leaf growth. They are designed to meter-out the nitrogen over a longer period of time. The slow-release forms of nitrogen do not have to be applied as often.

What fertilizer should I use?
Most turf experts recommend that a lawn fertilizer should have at least one-half of its nitrogen in one of the slow-release forms mentioned above. In most cases, both cool season and warm season grasses will do well when a 3-1-2 or 4-1-2 ratio of N-P-K is used on an established lawn. Some analysis numbers that meet these ratios are: 12-4-8, 15-5-10, 16-4-8, 21-7-14 and 20-5-10.

How much fertilizer should I use?
Fertilizer application rates should be as low as possible and still produce a high quality lawn. Over-fertilization weakens your lawn and causes excess leaf growth. As a general rule, if the amount of Nitrogen (N is the first number in the analysis) is between 5 and 12, the application rate should be 8 pounds per 1,000 square feet. If the N number is between 12 and 18, the application rate should be 6 pounds per 1,000 square feet. Any N number over 19 should be applied at a rate of 4 pounds per 1,000 square feet. Always follow the recommended rate stated on the bag by the manufacturer.

When should I fertilize?
The best time to fertilize a lawn is when it is actively growing. For Northern lawns (Cool Season grasses), begin the fertilization program as the grass begins to grow in the spring and reduce applications as the weather gets hotter. When cooler weather returns in the fall, the lawn can again be fertilized. A late fall fertilizer application after the first frost can increase lawn quality the following spring. For Cool-Season grasses, it is usually best to concentrate a larger amount of nitrogen during the early fall growing period and a lesser amount in the spring.

Southern lawns (warm season grasses), flourish during the warmer summer months, and therefore tend to require fertilizing shortly after green-up in the spring and again in the late summer months. For Warm-Season grasses in the southern areas, it is best to concentrate a larger amount of nitrogen during the early-late spring applications and a lesser amount in the fall. The fertilization program should start just after spring green-up and stop about two months before the average frost date in the fall. Frequency of fertilizer applications depends primarily on the amount and form of nitrogen used. The slow-release type fertilizers can adequately feed the lawn from 6 to 10 weeks. If the lawn still looks good and is growing well after 6 to 8 weeks, wait longer for the next application.

IMPORTANT: By leaving your grass clippings on the lawn, you are adding nitrogen almost continually, which can reduce the need for fertilization by as much as 25%. And, leaving the clippings on the lawn (grasscycling) helps the environment by keeping clippings out of our community landfills!

4. DETHATCHING: Thatch is that tightly packed layer of dead and living shoots, stems, and roots that develop between turfgrass and soil surface. As it is, dethatching takes a little time and effort and using the wrong dethatching equipment can make it a Herculean effort when it needn't be. Some dethatching machines have flexible, leaf rake-type tines that are ineffective in removing thatch. Spring tines that attach to a rotary mower blade aren't good for dethatching and can damage your mower. It's important that you use the right equipment if you are going to dethatch. Don't attempt to remove the entire thatch layer in one treatment and do not dethatch when soil is wet; only dethatch your lawn when it is needed rather than on a routine basis.

Recommendation: A little thatch is desirable, since it helps moderate temperature extremes at the soil surface and provides a cushion effect on the surface but too much thatch can present some negative consequences. To determine if your lawn has a thatch problem, remove a small, plug of turf several inches deep. Note the spongy layer of material between the turf and the soil. If this layer is more than 3/4 to 1 inch thick when you compress it, you should consider having your lawn dethatched or begin program which will encourage thatch decomposition. If you need to dethatch your lawn there are garden centers and equipment rental outlets that rent dethatchers. These machines are known as vertical mowers, verticutters, dethatchers or power rakes and they have vertically spinning blades which pull some of the material to the surface as they slice the thatch layer. Mechanical dethatching should be done in either late summer or fall when cool weather prevails. As is the rule when operating any equipment, follow the manufacturers or rental store's operating procedures. The organic material dislodged by the dethatching machine should be removed and composted. It's also important to note that grass clippings do not cause thatch and they are good for your lawn.

5. AERATION: Aerating a lawn is usually recommended when the soil becomes compacted and water and nutrients can't get to the roots of the plant. Lawn aeration equipment will pull "cores or plugs of soil out of the ground, letting air in. These plugs should be 2"-3" in depth. Such a plug should be pulled out of the lawn at about every 3". The plug-removal process is facilitated by watering the lawn the day before, but don't water to the point of muddying the soil. One of the most frequently made mistakes is the lack of sufficient cores or plugs removed from the lawn. If the tines of the aerator are set more than three inches apart, and only one pass is taken on the lawn, the effort may not have been sufficient to solve the problem. Two passes may be required to ensure that air, water and nutrients can get down to the roots. 

Take care to mark all sprinkler heads so that they can be avoided with the aerator. This will save on costly repairs to the irrigation system.

Recommendation: Core aeration, a process where plugs of soil and grass are removed at regular intervals, can be done either by renting equipment or hiring a professional. A cool, dry fall day is the perfect time for this beneficial chore. Core aeration reduces compaction in heavy clay soils, permits a more rapid exchange of oxygen and water with grass roots and reduces the thatch layer on lawns. The soil and grass plugs can remain on the lawn since they will gradually decompose and return all their nutrients to the soil. Often times, two passes in the form of a criss-cross pattern are recommended to make sure aeration is sufficient. Leave plugs on the lawn as they will eventually breakdown and return nutrients to the soil.

The type of grass will determine whether to aerify in the fall or in the summer. Lawns composed of cool-season grasses such as Kentucky bluegrass and tall fescue are best aerified in the fall, when there is less heat stress and danger of invasion by weedy annuals. Allow at least four weeks of good growing weather to help the plants recover. Warm-season grasses such as zoysiagrass, centipedegrass, carpetgrass, St. Augustinegrass and bermudagrass, on the other hand, are best aerified in late spring and summer, when they are actively growing. With either type of grass, choose a day when temperatures are mild and soil is moderately moist, which makes the soil easier to penetrate. Avoid aerifying a wet soil, as it is messy and leads to further compaction of the soil as well. If the soil sticks to your shoes or if the core samples you take stick to your probe, you should wait until it dries out some before starting the job.

Pests can completely destroy your lawn, so if you think you may have a pest problem have it taken care of soon! There are many types of lawn bugs. Below is a list of a few lawn bugs in Idaho. Remember that a healty lawn is a good defense against insect pests.

1. Grubs What are they?

Grubs are the larval form of much more destructive insects, like Japanese beetles.

Which stage does damage?

Unfortunately, each stage of the grub can do damage to the garden.  Grubs eat the roots and stems of young plants.  Moles like to eat the grubs and are drawn to lawns with high grub populations.  Moles make tunnels and runways in the lawn.  Any grubs that are allowed to mature turn into Japanese beetles, which chow their way through prized plants like roses.

How do you get rid of them?

The best way to rid the garden of grubs is to apply Milky Spore, a bacteria that destroys the grubs.  This needs to be applied to the lawn at the proper time to work-when grubs are young.  This treatment works especially well when entire communities inoculate their lawns at one time.  The bonus effect of controlling grubs is that you also control moles and the adult grub populations, as well.

2. Chinch Bugs What are they?

Chinch bugs are one of the rare lawn insects that is found all over the United States. The adult orm is scarcely bigger than a ladybug.  They damage plants by sucking the juices out of the leaves.

Which state does damage?

The larval form does the most damage to lawns, hatching in April and May, and feeding on grass during the hot, dry summer months.  They overwinter as adults in the thatch layer of grass.

How do you get rid of them?

It is very difficult to rid a lawn of chinch bugs.  One of the most effective treatments is to plant resistant grass.  Some types of St. Augustine are more resistant to chinch bugs than other grass types.

3. Billbugs What are they?

Billbugs are the worst pests of Kentucky Bluegrass lawns.  The larvae of these bugs look like small grains of rice.  They feed on the stems of the grass, right at the base of the stem, which caused the grass to turn brown and die.

Which stage causes damage?

These bugs overwinter as adults.  The adults lay eggs in April and May, and the larvae commence eating the grass blades.  They turn to adults around the end of October.  These lawn insects begin to overwinter in late October in piles of leaves.

How can you get rid of them?

To keep these lawn insects out of your yard, it is best to discard leaf piles, or not keep leaf piles near the turf.

4. Sod Webworms What are they?

Adults are sometimes called “sod moths” because they fly up when disturbed from the grass.  They lay eggs as they fly, which become the ravenous caterpillars.  They overwinter as caterpillars in the soil, only to emerge in the spring to become adults and breed.

Which stage causes damage?

Sod webworms cause damage mostly in the caterpillar form.  They stay in this larval form for most of the year, eating everything they can reach.

How can you get rid of them?

The best way to rid your lawn of these pests is to irrigate and fertilize regularly.  Grass that is stressed is most susceptible to pest damage.

Not all lawn insects are destructive, but the insects described are both destructive and highly prevalent.  For a healthy lawn, it is best to keep these lawn insects under control

Cool season grasses On average, these climates have cold winters and warm/hot summers. Usually they also have regular intervals of rain throughout the summer months, but grasses will tolerate some extended periods of draught by going dormant.

Transition zone grasses There is a “transition zone” between northern and southern turf regions, which follows the lower elevations of Virginia and North Carolina west through West Virginia, Kentucky, Tennessee and Arkansas and includes southern Ohio, Indiana, Illinois, Missouri and Kansas. In this transition zone, neither warm nor cool season grasses are uniformly successful. However, several of the northern or “cool season” grasses, such as Kentucky bluegrass and perennial ryegrass and tall fescue, do well across Kentucky, Virginia, West Virginia and Missouri. Tall fescue is the best choice in Tennessee, North Carolina, northern Georgia, northern Alabama and the Texas panhandle. In the lower elevations of these latter states warm season grasses do well too.

Warm zone grasses In some ways, growing and maintaining a good-looking lawn in the South is more involved than in the North. Choosing grass varieties is trickier; many grass varieties do much better when started as plugs or sod than from seed, as is usually done in the North. Good soil is critically important for growing a low maintenance lawn in this region. Most all warm weather grasses will turn brown when cooler temperatures arrive. Some southern gardeners seed their existing lawns with ryegrass each fall to maintain green color during the winter months. This is called “winter overseeding.”

Maintaining ideal growing conditions for your particular grass type is critical, otherwise unwanted grass varieties will start popping up and will be extremely difficult to remove. For example, St. Augustine grass being invaded by Bermuda and vice versa.

Mixtures and Blends Cool-season grass seeds are frequently packaged in either a mixture or a blend. Mixtures have two or more species of grass, and blends contain two or more cultivars of the same species.

There are many advantages to planting a mixture or blend. For one thing, the turf will be more resistant to diseases and pests, because each cultivar or species has its own strengths and weaknesses. Since most lawns have a variety of growing conditions, different grasses can grow where they are best adapted within your lawn.

In a typical grass seed mixture containing bluegrass, ryegrass, and fine fescue, the fescues will thrive in shady portions of the lawn, while bluegrass likes sunny areas. If conditions should turn adverse for one grass, you won't lose the entire lawn, just the part that's made up of the susceptible grass.

Unlike cool-season grasses, warm-season grasses tend to be planted as monostands, meaning a single type of seed is planted, not a mixture. Their growth via stolons and rhizomes makes them so vigorous that other grasses cannot compete.

Because of their distinctive appearance, some grasses, such as the original tall fescues and most native grasses, also look better planted alone.

Grass seed labels Thanks to the passage of the Federal Seed Act of 1936, grass-seed labeling must meet certain requirements. You'll know at a glance what is in any given box of seed, including what percentage of the seed will germinate.

When you shop for seed, compare brands closely and remember the adage, "the lawn you grow is no better than the seed you buy." The extra expense for higher-quality seed is usually worth it.

Check labels and avoid mixtures containing lower-quality grasses, like timothy, meadow fescue, orchard grass, tall oatgrass, and annual ryegrass.
