Spring is an especially important
season for your lawn grasses. What you do or don�t do in the
Spring can effect how your lawn looks year round. Basically
what you do to your lawn in the spring is setting the
foundation for a good growing season. There are basically
eight steps you should take in the Spring to insure that you
have a good foundation set for your lawn to prosper into the
summer and fall.
Equipment
Maintenance
I quite often see this as one of the
last steps in a spring lawn prep program. I have to part from
the crowd on this one. I can�t see why you would want to take
care of your equipment after you�ve completed your Spring
maintenance.
Better to get all
your equipment in shape before, that way your not trying to cut the grass
with a dull mower or any other horticultural atrocities. If
you haven�t done it in the fall now is a good time to
sharpen the blades on your mower, do an oil change (Note, don�t
change your oil over your lawn, any spills on the the grass will probably
result in a patch of dead grass). Check your rake and
straighten out the tines if necessary. Have you ever used a rake
that had bent times and gone over the same spot a
dozen times without getting the debris you were trying too? Check you
Fertilizer and Seed broadcaster (spreader) oil if necessary,
add air to the wheels and make sure they are free and clear of
old chemicals. Same for your sprayer if you have one, clean
out any old water or chemicals test to make sure it works and
replace any seals or gaskets that may have
deteriorated.
Cleanup
Now is the time to get
rid of twigs, leaves etc. A thorough raking of the lawn is in
order. It isn�t necessary to dig in with the rake but it is
important to get rid of the debris so that your fertilizers
and amendments as well as water have a chance to reach the
soil.
Mow
You could of course
be tempted to mow over all the winter debris but I wouldn�t
advise it. A nice mowing, preferably on the high side for your
grass type is a fundamental start to all the next steps you�ll
be taking. Check out the section on
mowing for mowing
tips.
Aerate
I am a huge fan of
aerating lawns. This is a key factor in your Spring Lawn prep.
De-Compacting the soil, giving it room to open up and allowing
the fertilizers to work their way into the soil is, in my
opinion, one of the most important things you can do for a
lawn. Whether you buy a pull behind core aerator or rent a
power aerator, make sure it is a core or plug type aerator.
The holes left behind will quickly fill in and the plugs will
disappear back into the lawn bed over the next few weeks. Your
lawn will love you for it! Here is a section dedicated to
aerating that
will be helpful.
Dethatch
I�m not a big fan of de-thatching, I
prefer to aerate and let the action of the aeration break into
the thatch and help it along in decomposition. Many lawn
experts highly recommend thatching so I have to believe there
are circumstance where thatching is appropriate. I believe
that this is chiefly with grasses that grow in clumps such as
fescue�s. Grasses that grow via rhizomes and develop a mat of
interlaced �runners� can benefit as well. My only caveat is
that I would hire someone with a power de-thatcher rather then
use a pull behind detatcher with the steel tines on it. A
power de-thatcher will cut and pull the thatch up. A pull
behind de-thatcher will tear apart the network of rhizomes,
you lawn will recover but wont look very pretty after your
done.
Fertilize & Add
Amendments
Now is the time to fertilize, giving
your grass the nutrients they need promote healthy growth. As
a rule I dislike fertilizing in the summer. The warm season
grasses tend to tolerate summer fertilization well but cold
season grasses such as fescue will not do well with high
nitrogen application, especially when the temperature is over
90F.
Your grass will benefit from other
amendments as well. Lime is the most common amendment and
should be added if your soil alkalinity is to low, in most
cases it is ok to add lime to almost any grass type without
testing. Don�t Lime Centipede or Carpetgrass though unless you
have had your soil tested and the alkalinity is extremely low.
Centipede and Carpetgrass prefer acid soils and lime will
generally create an environment that Centipede and Carpetgrass
will not thrive in.
Iron is another
amendment that should be added at this time. Most experts
agree that iron should not be added if the temperature is over
90F. Some fertilizers already have an iron amendment in them,
if yours does not then products such as Ironite, chelated
iron, or ferrous sulfate can be added at this time to prevent
iron chlorosis. Plants require iron to manufacture
chlorophyll, High PH as well as other environmental conditions
can deplete your lawn of iron, resulting in yellowing or
browning of the grass. Here is a link to a page on this site
dedicated to
Lawn fertilization .
Herbicides, Pre-emergent�s,
Insecticide
A well kept and healthy lawn should
have little problem with weeds as the dense turf and frequent
mowing should keep out any weeds. However, since this is
reality we are all occasionally plagued with weeds, crabgrass
and other noxious plants. A pre-emergent is probably the best
solution, applied in the spring this will help keep the weeds
down and allow the lawn to develop a dense turf to further
control weeds. One consideration to take into account now is
whether you will be overseeding, if you are the use of a
pre-emergent or herbicide is NOT recommended.
Since we keep a number of pets I
generally apply Insecticide to my lawn several times a year. I
usually don�t start applying until late spring and continue
every four weeks until late fall. There are a number of
insecticides suitable for use on lawns, most are broad
spectrum so will work on fleas and ticks (Which is as a pet
owner is one of my concerns). I prefer a liquid application as
it is more economical. However, a granular application tends
to last longer.I don�t think there is really any difference in
overall effectiveness between the two.
Overseed and Top Dress
If you have any bare spots in the lawn
that you did not overseed in the fall then you should tackle
those spots now, in the early spring for the cool season
grasses and in the late spring or even early summer for the
warm season grasses. Preparation is much the same as if you
were seeding a new lawn, just on a much smaller scale. Loosen
the first several inches of soil, remove debris and rocks, rake
in the seed to the desired depth for the grass variety you
are planting and put a thin layer of mulch such as
wheat straw over it. If you have access to a roller it
is a good idea to roll the seed in as
well. Water daily for the first several weeks and gradually space out
the watering until your seedlings have matured and have at least three or
more leave per plant.One exception to this is centipede, I like to wait until
later in the spring season, even early summer before overseeding. Even then I
use a nurse crop such as carpetgrass since centipede is
a very slow grower and wont germinate until the soil is
consistantly warm.
Top dressing is an option at this time
of the year. For those of you that have poor soil condition
top dressing with peat moss or screened topsoil may be a good
idea to help your lawn along in the summer.
