Lawn Care Tips
A beautiful
lawn does not come without some effort. Depending upon what type
of soil you have, the amount of effort will vary. For instance
when raising trees and shrubs, sandy or a gravel base soil is
great. Landscape plants like well drained soiled. A lawn on the
other hand is different. Lawn grasses grow constantly throughout
the growing season, and need an ample supply of both nutrients
and water.
The most basic
of lawn care tips includes regular watering and fertilization is
required to keep a lawn beautiful. If you’re lucky enough to
have a lawn that was originally planted in good rich topsoil,
you won’t have to work near as hard as somebody like me, who
has a lawn that is planted in sandy gravel. The soil at our
house has little nutritional value, nor does it have the ability
to retain any amount of moisture. By mid May my lawn starts
drying out. It is very difficult for us to keep our lawn looking
nice.
Lawns are one
area where a little clay in the soil is a good thing. Of course
standing water is not good, but having soil that has the ability
to retain some moisture is helpful. If you happen to be
installing a new lawn, here's a news flash from my lawn care
tips that will make all the difference in the world: Add
lots of organic matter before you install your new lawn if you
have sand or gravel type soil. The easiest way to do this
is to find some good rich topsoil and spread that over your
existing soil.
Because most
lawn grasses grow so vigorously, they need additional amounts of
nutrients added in order to stay looking nice. Just use one of
the four step programs offered by the fertilizer companies. Most
of these programs also include weed control along with the
fertilizer. Here in the north we basically have two concerns
with weeds in our lawns.
Crabgrass can be
a problem, and I do consider it a weed. In order to control
crabgrass you must use a pre-emergent herbicide that will
prevent the crabgrass seeds from germinating. In order for this
herbicide to be effective you must apply it early in the spring
while the soil temperature is still below 45° F.

Broadleaf weeds
such as Dandelions are another problem, although fairly easy to
control with a broadleaf weed control. Most broadleaf herbicides
are mixed in with the fertilizers, and must be applied when the
grass and weeds are damp. The wet foliage will cause the
herbicide to stick to the weed, giving the herbicide time to be
absorbed by the weed. Once absorbed the herbicide translocates
through the weed plant and kills it completely.
These types of
herbicides are considered “selective” since they seem to
know the difference between a grass plant and a weed. That’s
why they only kill the broadleaf weeds and not the grass itself.
However, many people have different kinds of thick bladed grass
in their lawn such as quack grass. Quack grass is on the
ugly side, and can really detract from a lawn. The problem is,
it is still in the grass family, and “selective” herbicides
leave it alone because it is a card carry member of the grass
family.
So what’s a
person to do?
In order to get
rid of these thick bladed grasses you must use a
“non-selective” herbicide, and “non-selective”
herbicides don’t care who they kill. Well, at least that’s
true in the plant kingdom. When you use a “non-selective”
herbicide you must understand that everything that you spray is
going to die, but it really is the only effective way to rid
your lawn of undesirable thick bladed grasses. This type of
treatment is effective if you have isolated areas that contain
wide bladed grasses. You’ll have to spray all the grass in the
area, then reseed with good quality grass seed.
My herbicide of
choice for this type of spraying is RoundUp®. It is believed
that RoundUp® does not have any residual effect, which means
that it does not linger in the soil. That means that the new
grass seed or the young grass plants will not be affected by the
herbicide. Being a non-selective herbicide you must be careful
when spraying, making sure that the spray does not drift onto
other plants or lawn areas that you do not want to kill.
To keep the
spray from drifting adjust the nozzle so that the spray pattern
is narrow with larger spray droplets. You do not want a fine
atomized spray if there is danger of spray drift. It also helps
to keep the pressure in the sprayer as low as possible. Pump the
sprayer a minimum number of times, to keep the pressure low. You
just want enough pressure to deliver the spray, but not atomize
it to the point that it can be easily carried by the wind.
Buy a sprayer
just for herbicides and mark it as such. You never want to spray
plants with a sprayer that has been used for herbicides.
Once you have
sprayed the area you want to kill, wait three days before doing
anything else. After a period of three days the grasses that you
sprayed may not look any different, but if they have been
properly sprayed, they will die. It takes three days for the
herbicide to translocate throughout the entire plant, then the
plants will die. So even though the weeds and grass plants look
fine, you can start digging and chopping and not worry about
them growing back. If you start digging and chopping before the
three day period you will interrupt the herbicide, and the weeds
and grass you were trying to kill may come back.

If you happen to
be installing a new lawn, make sure you spray all the weeds and
thick bladed grasses before you start. Once you have the lawn
installed, you sure don’t want to go through all the trouble
of killing areas of your lawn and reseeding. If you make sure
that all of these undesirables have been killed before you
start, you’ll be way ahead of the game.
When selecting
grass seed, you should always use a blend that is recommend for
your area. Here in the north a popular blend contains fine
bladed perennial rye grass, fescue, and blue grass. Keep in mind
that it takes blue grass seeds 28 days to germinate, while most
perennial rye grasses germinate in 5 or 6 days, so you never
want to plant a lawn that is 100% kentucky blue grass. Before
the blue grass seeds have a chance to germinate, every kind of
weed imaginable will already be actively growing in your lawn.
With a blend,
the faster germinating grasses come up quick, and act as a nurse
crop for the slower germinating seeds. Having a blend also gives
you some protection in case some new pest comes along that
attacks certain types of grasses.

People often ask
if they have to have their lawn hydro-seeded in order for it to
be nice. The answer is no. Hydro-seed is not some kind of magic
formula. It is nothing more than a fancy way to apply grass
seed. A hyrdo-seeder is just a machine that mixes water, grass
seed, fertilizer and mulch into a slurry that is sprayed onto
your lawn. The ingredients are exactly the same that you would
use if you seed by hand, with the exception of the mulch.
And contrary to
popular belief, hydro mulch is no better than good old fashioned
straw. In my opinion straw is a much, much better mulch. The
primary advantage to hydro-seed is that the grass seed is
thoroughly soaked before it is applied, which assures
germination. That’s a huge advantage if your seeding along a
freeway where it is not practical to wet the seed after it has
been applied. At your house, it really doesn’t mean much. Hand
seeding works just fine.
With either
method, you still have to water just as much once the seeding is
done. Many people are lead to believe that hydro-seed doesn’t
have to be watered as much as hand seed. This is a huge
misconception. If you fail to water hydro-seed once it is
applied, it will still germinate and little tiny grass plants
will appear. But just a few hours without water on a hot day,
and those little tiny grass plants will wither and die. This is
a big problem because once the seed has germinated, it is spent.
All the water in the world will not make that spent seed produce
another grass plant.
Hydro seed has
it’s benefits, but for the residential lawn it’s not all
that important. Why do I claim that straw is a better mulch than
hydro-mulch? Think about how the hydro-mulch is applied. It is
mixed with the seed, fertilizer and water as a slurry, and
sprayed on the lawn. The mulch has not been applied over top of
the seed which is how mulch is supposed to be applied, it is all
mixed together. Some of the seeds are under the mulch, and some
of the seeds are on top of the mulch. Mulch can’t do much good
when the seeds are resting up on top of it. They might as well
be sun bathing!
Now think about
the process of hand seeding. The seed is spread on the soil,
then you should take a push broom and drag it backwards over top
of the seeded area. This applies a very thin layer of soil over
most of the seeds. Then you spread the straw over top of the
soil. The pieces of straw are scattered in all directions, with
many of them criss-crossing each other.
Remember the
movie, “Honey I shrunk the Kids”? The part where they are
walking through the lawn and the blades of grass are huge
compared to them? This is what it’s like to be a grass
seed under a mulch of straw. Those little tiny grass seeds are
lost under the straw, and that's exactly what you want to
protect them from the intense rays of the sun.
As the sun
works it’s way across the sky the grass seeds actually receive
filtered sunlight. Enough sun to warm the seeds so they grow,
but also enough shade to protect the tender young grass plants.
As the grass plants grow, they also raise the mulch with them to
a degree, providing additional shade for the seeds that
haven’t germinated yet. The shade that straw mulch provides
also helps to retain the moisture around the seeds. Grass
seeds will never get this kind of protection from hydro mulch.
Another trait of
hydro-seed is that as the slurry dries, it becomes a blanket
over the lawn. In the event of a heavy rainfall, running water
tends to get under this blanket and carry it away, leaving big
areas with no seed at all. They make a glue that you can
actually add to the hydro seed mix, but my experience has shown
that the glue will hold the hydro seed in place a little longer,
but when it does wash out much larger areas wash because they
are glued together.
With hand
seeding, each seed is independent, and they fall between the
nicks and crannies of the soil. In the event of heavy rain, the
running water must be severe enough to wash the soil away before
the seeds can be moved. I’ve installed hundreds of lawns using
both techniques, for the difference in cost I’ll take the hand
seeded lawn any day.
