Lawns and Landscaping
- If runoff is a problem in your landscape, lawns established
with turfgrass sod are up to 15 times more effective in
controlling runoff than seed-established lawns, even after three
years.
- Warm-season grasses, including bermudagrass, zoysia grass, and
centipedegrass, should be fertilized with 1 pound of nitrogen per
1000 square feet of quickly available nitrogen fertilizers (with
less than 50 percent slowly available nitrogen). This application
should be repeated in May and June.
- Bluegrass uses the most water of the lawn grasses. Fescues are
between ryegrass and bluegrass in water consumption.
- Control lawn weeds now through late May before they get large,
and temperatures get too high to apply herbicides safely.
- The first grass clippings of the season are rich in nutrients
and contain fewer weed seeds than those collected later. Put them
in the compost pile or mow frequently and leave them on the
ground.
- Where flower gardens or window boxes are visible from indoors,
select flowers in colors to complement your curtains or porch
decor.
- An important principle of garden design to remember is to have
your plants in groups large enough to form masses of color or
texture. As a rule, five or seven plants set a in grouping to
form an irregular shape creates the desired effect. A large
delphinium or peony may be of sufficient size to be attractive
alone, but a random collection of individual, small- to medium-
sized plants will yield a disorganized appearance.
- A well-designed berm or man-made hill is a landscape asset.
Even a low berm adds considerable interest on a flat property. A
berm will provide screening for privacy, deflect and absorb noise
or redirect wind or water flow where necessary. It can also
improve the microclimate for plants; its south side staying
warmer, the north side cooler.
- A tall, evergreen hedge north of your home can cut heating
bills by 34 percent in windswept regions or by 10 % in sheltered
areas. If your house is exposed to winter winds, this spring,
consider establishing an evergreen planting for a windbreak.
- Many herbs are excellent for natural-appearing rock gardens or
formal plantings with brick pathways. These herbs do well in
sandy soil and are partial to full-sun locations: creeping thyme,
sage, santolina and garlic.
- Estimate your grass seed needs at 2 to 3 pounds of bluegrass
seed or 4 to 8 pounds tall fescue per 1000 square feet. Remove
debris, level and firm soil before seeding. Cover seed by raking
the area lightly.
- Do not mow the lawn until it has grown at least two inches. The
roots are being renewed in the spring and grass needs vigorous
top growth initially.
- Plant grass seed to fill in bare spots in your lawn. Loosen the
soil to a depth of one-half inch with a spade or rake. Sow a
good-quality seed with a low percentage of weed content and a
high germination rate. Spread the seed liberally and work it in
lightly. Use a fertilizer designed to encourage root development
in new lawn areas. Gently water the newly seeded area. Keep it
moist, but not flooded. Use a mulch, such as straw, to retain
moisture.
- Lawn grasses do best if mowed at the correct height:
Kentucky Bluegrass 1 1/2 to 2 1/2"
Tall Fescue 1 1/2 to 3"
Creeping Red Fescue 2 to 3"
Perennial Rye Grass 1 1/2 to 2 1/2"
Bermudagrass 1/2 to 1"
Zoysia Grass 3/4 to 1"
- Once the snow melts and the surface is dry, established (but
uneven) lawns will benefit from being rolled. Depressed areas may
be filled with shifted topsoil. Fill in the sparser areas by
sowing new seed.
- The lawn mower blade should always be sharp so as not to tear
the grass. If you sharpen the blade at home, be sure to balance
it, too. Place the center hole of the blade on a screwdriver
handle held upright in the vise. Check to see if it balances. If
not, sharpen the heavier side some more until the blade balances
on the handle.
- Remove sticks, rocks and other debris from your lawn to prevent
damaging your lawnmower or injuring yourself when mowing. Check
your lawnmower and other lawn-care equipment in preparation for
the coming season.
