How to reduce lawn size
Large lawns are beautiful, but the cost is high.
|Fuel for power mowers, toxic emissions, fertilizers and pesticides, water consumption
and your weekend time are all part of the cost of lawn maintenance. Hiring a
lawn care service will save you the time and energy, but the environmental costs
|Reducing the size of your lawn can benefit the environment while saving you time, energy and expense. And the result need not be a loss in aesthetic appeal.|
|Here are a few suggestions to help you reduce lawn size:|
These are plants which spread across the ground but do not grow tall, so no cutting is required. Areas planted in groundcover need little to no maintenance. Groundcovers are usually chosen for texture, density and how well they spread and choke out the weeds. They enhance the soil by acting as a mulch, and some groundcovers are nitrogen-fixing.
varieties are available, including flowering groundcovers which offer color
and add emphasis to the seasons. Although groundcovers are usually perennials
and evergreens, annuals make excellent groundcovers as well, but do require
more work each spring.
Some groundcovers are edible, such as strawberries or low-growing herbs. Ever-bearing strawberries produce fruit most of the summer and tolerate marginal soils and light shade. Dwarf dogwood (also called bunchberry), and herbs like thyme and oregano work as groundcovers for limited areas.
During the first year, new plantings of groundcover will require weeding and mulching, but once established, little care is needed.
need an edge barrier to contain them. A low brick or wood edging, or any lawn
edging which cuts down a few inches into the soil will usually be sufficient.
Your garden center can recommend local groundcover varieties and their characteristics.

Clover is often planted by gardeners as a soil conditioner. It grows quickly and easily, chokes out weeds and is easily 'turned in' to the beds when planting time draws near. The deep root system reduces soil compaction. Clover is also a nitrogen-fixing plant, which enriches the soil with natural fertilizer.
also works well, however, as a replacement for turf - consider the benefits:
|Commonly available clovers are Dutch White, Yellow Blossom and Red Clover. Of these, Dutch White is best suited for lawn-type use. (Yellow Blossom and Red Clover grow taller, from 18 - 36". They are more suited for pasture application.) Dutch white clover is often blended with lawn seed for its value as a natural fertilizer and because it grows well in poor clay subsoil common around new home construction.|
|Dutch White clover is a perennial, but acts as a reseeding annual in the Lower
South. It is an excellent reseeder because it flowers from March through early
May. Dutch White clover germinates in 7 - 10 days, and grows to a height of 4-
8". White clover does need moisture at time of germination, but is drought tolerant
Dutch White clover is an effective alternative to lawns because:
- it is relatively low-growing, at about 4 - 8" high
- tolerates low mowing well
- stays green through droughty periods of summer
- tolerates dog urine
Clover is not durable enough for playing surfaces or high use areas. It is torn up easily by pet activity such as dog runs, and is not suitable for this purpose.
You can convert part of your lawn to a display of ornamental grasses. These grasses are low maintenance and grow well in most soils. They seldom require fertilizer, and have few pest and disease problems. Ornamental grasses are also drought-resistant and low maintenance. When choosing ornamental grasses for your yard, consider the characteristics of each variety. They are categorized as:
grasses grow best at temperatures ranging from 15
to 24° centigrade ( 59 to 75° farenheit ). New growth starts as
soon as temperatures rise above freezing in spring, in temperate climate
zones. Growth slows and flowers bloom by early summer.
Warm-season grasses prefer temperatures ranging from 26 to 35° C ( 78 to 95° F). New growth begins after the soil warms up to 16° C. Growth slows and flowers starrt to bloom by mid-summer, and continuing through fall.
Running-growth habit: Ranging from slow creepers to agressive spreaders, running grasses are useful for erosion control on slopes or as ground cover.
Clumping-growth habit: These grasses grow in tufts. They make fine specimens and are also effective planted in groups or masses. Most ornamental grasses commonly used in gardens today are clump-forming.
|Tips for Growing Ornamental Grasses:|
Most grasses prefer a sunny area, especially the
more brightly colored varieties.
Water new plantings. Drought-resistant grasses still require watering while getting established.
Space generously. When planting, allow room between clumps for movement.
Trim. Clump grasses can be cut back with a shears each spring to allow for fresh new growth. Grasses which turn brown in winter (deciduous) can be cut back to a few inches of the ground. Evergreen grasses, however, should not be cut back too drastically.
Divide. Clump grasses may need to be divided if they get too big or have die-back in the center of the clump. Use a pointed spade (or a hand trowel for smaller clumps) to cut larger divisions; pull apart by hand into smaller sections. Be sure to water replanted divisions.
& Shrub Beds
Flower and shrub beds can be strategically located to add color and interest while expanding the "low maintenance" areas of your yard. Terraced beds are a good solution for sloped areas which are difficult to mow. Beds of shade-loving varieties can be planted beneath trees with low-hanging branches or protruding roots which cause mowing problems.
Here are a few suggestions for designing and locating flower and shrub beds:
~ Choose native perennials.
Ask at your local nursery for recommended local perennial flower and shrub varieties. Native plantings will require less attention and less fertilizer, and are your best guarantee of good results. Perennials will require occasional dividing and replanting as they grow. Divided sections can be given to friends as gifts. When choosing shrubs for your landscaping, be sure to find out the height and width of the shrub at maturity. This will ensure that you plant them the right distance from each other.
~ Choose low-maintenance varieties. Ask your nursery to recommend varieties which don't need to be pruned, regularly divided or staked as they grow tall.
~ Mulch plantings.
Spread mulch around the base of plants at least 2 inches deep. This will save water and keep the soil loose and aerated. Mulching slows water evaporation and prevents weeds from taking over. Over time, mulch gradually breaks down into the soil and often needs to be reapplied once or twice during the growing season. Common materials used for mulching include:
Ideal for use as mulch, whether green or dry. Too thick a layer, however, will cause the clippings to mat together and reduce air flow. Use grass clippings in layers of an inch or less, or mix with other mulch material such as straw or leaves. Grass clippings can be interspresed withother mulches to prevent matting.
Can be a bit acidic for flower beds, but bark is commonly used for larger plantings, such as trees and shrubs. Lime can be added to reduce acidity if required. It is a common practice to first lay down a covering of landscape cloth, then apply the mulch over the top. When buying bark mulch, ask the supplier if there have been amy reports of weed seeds in the bark which may sprout in your shrub beds.
A thick layer of leaves will help retain soil moisture and prevent root exposure and surface drying. Maple and Alder leaves are best, as they return nitrogen to the soil during decomposition. Large leaves, however, tend to mat together; they work best when dried and shredded. Some gardeners use a lawnmower to shred leaves before using as mulch. It is helpful to sprinkle some soil over the leaves to help them stay in place during windy weather. Leaf mulch will need to be renewed periodically, usually once a year.
Coarse sawdust works as a mulch, and the light color of sawdust helps reflect heat. Check the source of the sawdust - chainsaw sawdust contains oil. Sawdust from certain wood species, such as cedar, may be too acidic for good growing conditions. Avoid using thick layers of sawdust, as it tends to clump together and block air and nutrients.
A good light-coloured mulch, which will reflect heat away from the soil. Straw, as opposed to hay, contains fewer seeds which could sprout in your soil. Straw is commonly used as a mulch for vegetable crops, but is less commonly used to mulch shrubs because of its un-groomed appearance.
If you have access to seaweed, it makes an excellent mulch and soil additive. Seaweed shrinks considerably on drying, so use a thick layer and cover with grass clippings. This will retain moisture and reduce shrinkage of the seaweed, which can otherwise leave bare spots for weeds to poke through. Seaweed is also a deterrent to slugs. SOme gardenes prefer to rinse seaweed before applying in order to reduce salt, but this is not usually required.

~ Plant fewer varieties. A few varieties can make a big impact with less cost and effort. With many varieties, you'll be preoccupied with the specific needs of individual plants. Keep it simple.
~ Keep flower beds narrow, but shrub beds wide. For flowers which need occassional tending, keep beds no wider than 3' (1 meter), so it's easy to reach the back of the bed. Even if you have room to work on the back side, it gets tedious going back and forth to work the bed. With shrubs however, make beds wider. Planting shrubs closely will minimize weeds, and the wider beds allow you to reduce lawn size. Use local or regionally adapted shrubs for lowest maintenance.
planning how to reduce the size of your lawn, lawn shape should be considered.
Maintenance can be reduced and simplified by designing the lawn areas in
continuous, easy-to-mow swaths.
By eliminating corners, mowing becomes quicker and easier because you don't have to back-up and go forward repeatedly. Corner areas can be replaced with shrub or flower plantings which bring visual appeal while helping reduce maintenance.
the example to the right, the dark green shaded areas are plantings of
low-maintenance shrubs, groundcover or even small xeriscapes.
Although only about 25% of the original lawn area is given over to these plantings, the time and energy saved in cutting the lawn is almost 50%.
Continuous swaths, with no corners, will save you time when mowing.The narrow strip to the right of the driveway and the garage can be ground cover, bark mulch, gravel or a low-maintenance, drought-tolerant xeriscape.
in the lawn, such as trees or flower beds will slow down the mowing; better to
have one or two large islands than a number of smaller ones. Trees will
do better with bark mulch or ground cover planted beneath, as grass will
compete with the tree roots for nutrients. Trees
with low-lying branches can have ground cover planted beneath,
so the person mowing doesn't have to duck below the branches. Tree rings are available which separate the mulched area from the lawn and add visual appeal.
Trees in the lawn can have a wide skirting surrounding the base, using mulch, groundcover or native plants. A flagstone or brick border can be used to define the edge; set this border below the level of the lawn, so mowing is easy and no other trimming is required. This looks attractive and cuts down considerably on maintenance
Edges of the lawn can also be defined with inset flagstone, landscaping brick or slate. Set the edging below the level of the grass so the mower can go right over. This eliminates the need for edging. With careful planning, you can do without a weedeater for edging.
Lawns and Golf Courses
Large lawns, and especially golf courses, require large amount of herbicides and chemical fertilizers to maintain their condition and appearance. The impact on the environment is considerable.
Recent experiments using organic compost have shown this method to be very promising. Generally, researchers and practitioners recognize that incorporating high-quality compost does several things:
1. Adds food and nutrients for plants and organisms,
2. Adds a diversity of organisms to the soil,
3. Encourages plant growth promoting substances in soils.
